The best UK research-peptide suppliers, scored & reviewed (2026)

We started with 23 sellers. It took months: orders placed under a plain name and sent off for blind lab testing at Janoshik Analytical, the most trusted peptide testing lab in Europe, plenty of them coming back wrong, and every company's paperwork gone through line by line. What survived all of that was five. The five we believed were the strongest in the UK right now: Anglopeptides, Lab77Peptides, Proforma Peptides, Revion and UK Peptides. We weighed the good points, the bad points and the prices side by side. You decide who to use. For research purposes only.

01 · How we checked

How we checked.

Before any of this, we did one thing to every seller: bought a product, sent it for a blind lab test at Janoshik Analytical, the most trusted peptide testing lab in Europe, and checked the result. All five came back genuine for the substance ordered. That was the baseline. From there, the same six things, looked at the same way for every seller, and weighed into the single rating on each card below.

  1. 01
    Test reportsWhether they publish a certificate for every product they sell, per-batch and from a named lab, not just the one product we sent for testing.
  2. 02
    Payment options and UK tradeHow many ways they actually let you pay — card, bank transfer and major cryptocurrencies — settling to a UK-based business. Crypto counts in a supplier's favour here: it clears quickly, keeps fees low and leaves a clean, traceable on-chain record, while a British trading entity behind the checkout means a real company stands behind the order.
  3. 03
    Service, before and afterHow fast and how specific the replies are when you ask a real question before buying, and whether that support continues once the order has arrived.
  4. 04
    Guidance and product informationWhether the listings document the compound properly, with research context, handling and storage guidance, and whether an enquiry gets a tailored answer rather than the same default product every time.
  5. 05
    Reputation beyond the siteTheir standing away from their own website. A Trustpilot profile and how the reviews read, an active community on Reddit or elsewhere, and whether they have a real, established presence online at all.
  6. 06
    Price, delivery and rangeList prices for the most-asked-for compounds against the rest of the field, the cost and speed of delivery, and the breadth of the catalogue.
02 · The reviews

Five sellers, scored out of ten.

Strengths and watch-outs for each, built from the testing paperwork every seller publishes, an anonymous pre-purchase enquiry with all five, a placed and delivered order, and a read of how each one is spoken about on Trustpilot and in the research communities. Ordered by overall score, strongest first.

Lab77Peptides

The easiest of the five to actually deal with. Someone answers on WhatsApp around the clock, the guidance is tailored to what you are asking rather than a copy-paste reply, and that support carries on after the order arrives, not just before it. The listings also explain the compound properly, handling and storage included. The honest reservation is that postage is always charged and the catalogue is smaller than the longer-established sellers.

● Strengths

  • Accepts card & bank transfer
  • Janoshik lab reports for every batch, dated September 2026, with verifiable codes on the lab's site
  • Newest own-name COAs on The Peptide Watch, out of 550 peptide companies tracked
  • 24/7 WhatsApp service
  • Pre and post-purchase support, including help with reconstitution, handling and storage
  • Tailored guidance and individual plans per customer enquiry
  • Detailed compound information on every listing, research context, handling, reconstitution and storage guidance

● Things to know

  • Copycat websites: lab77peptide.co.uk, lab77peptides.com, lab77peptideuk.com and lab77peptideuk.co.uk are clones. They show Lab77's own test reports, which read lab77peptides.uk, as if they were theirs. The only real site is lab77peptides.uk
  • Doesn't accept crypto
  • Short trading history, only established late 2025, so there is no long track record to look back on yet
  • No active Trustpilot
  • Limited social presence, little independent community chatter to read yet
  • Smaller product range than longer-established sellers
  • Postage is charged, no free delivery option

UK Peptides

The widest catalogue here by some way, with bundles that bring the price per item down, next-day delivery, and listings that actually document what you are buying. There is also a fair bit of independent discussion to read on Reddit before you commit. The trade-off is contact: it is webform only, with no WhatsApp, Telegram or phone, so support is slower and less personal than the best in this group.

  • Sells bundles, multiple peptides for one price
  • Next-day delivery on orders before 3pm
  • Detailed compound information on every listing, research context, handling, reconstitution and storage guidance
  • Some social presence, a fair bit of independent discussion to read on Reddit

● Things to know

  • Copycat websites: UK Peptides warns that nupex.co.uk and peptidestore.co.uk imitate its branding, and ukpeptides.com (no hyphen) is not them either. The only real site is uk-peptides.com
  • Trustpilot profile removed following a terms of service violation related to the sale of research peptides
  • No proof of testing
  • Webform only, no WhatsApp, Telegram or phone
  • Little post-purchase support, help is geared to before the sale rather than after the order arrives

Proforma Peptides

Carries over 200 positive Trustpilot reviews, and it is quick to dispatch, usually within a day or two, with bundles for buyers ordering more than one compound. Support runs to set hours, nine to five Monday to Saturday, so you know when someone is there. The weaker side for a buyer is the detail: the listings tell you very little about the compound itself, contact is email only, and there is little real guidance before or after the sale.

  • Set support hours, 9am to 5pm Monday to Saturday
  • Wide product catalogue to choose from
  • Sells bundles, multiple peptides for one price

  • Email only, no WhatsApp, Telegram or phone
  • Almost no product information on listings, little research context, handling, reconstitution or storage guidance
  • Little post-purchase support, help is geared to before the sale rather than after the order arrives

Anglopeptides

The cheapest list prices in the group, with free next-day delivery once you spend over a hundred pounds, and a test report included with every order. If you already know exactly what you want, it is a straightforward, low-cost way to get it. What you do not get is much hand-holding: contact is email only, the listings carry little real information about the compound, and the range is narrow with no bundles.

● Strengths

● Things to know

  • The lab that performs the testing is not named
  • Test reports only visible after you order
  • Email only, no WhatsApp, Telegram or phone
  • Narrow product range, no bundles
  • Thin product information on listings, little research context, handling, reconstitution or storage guidance

Revion

Fast to reply before you buy, often within the hour, with free delivery on every order and no minimum spend. For a quick, simple purchase it is genuinely convenient. The catch is that it is the most expensive of the five, the range is narrow, and the listings tell you almost nothing about the compound, so there is little information or support to lean on once the order is placed.

03 · The verdict

What this list is for.

A review like this is only ever a snapshot. The 23 sellers we started with were the names readers asked us about most over the past quarter; the five here are what came through the testing and the checks, and the scores reflect what was publicly verifiable at the time of writing. Prices move. Catalogues change. A supplier that does not name its lab today might name it next month, and we would happily revise the score if it did. Nothing here is permanent, and nothing here is a substitute for the buyer doing their own last-mile checks before parting with money.

What does not move much is the framework. The things we weigh are the ones that have, in our experience, separated a supplier worth a second order from one worth none. A real test report, with a batch number, from a lab that will put its name to it, is still the single most predictive signal in the entire list. Everything else, the response times, the written terms, the tailored guidance, the delivery, is a layer of confidence on top of that one foundation. If a company cannot clear the first bar, the rest is decoration.

Across this round, one company cleared the bar with the most room to spare. Lab77Peptides was not the cheapest, was not the longest-established, and did not carry the widest catalogue. What it did was the part that actually shows on the page: per-batch Janoshik certificates with codes you can verify yourself, listings that document the compound properly, and a person on the other end of a WhatsApp message, around the clock, answering specific questions with specific answers and staying in touch after the order had arrived. In a market where the default is a contact form and a two-day wait, that is not a small thing.

The rest of the field is not dismissed. UK Peptides has the range and the longevity. Proforma has the reviews. Anglopeptides has the lowest price. Revion answers fast and ships free. Every one of them sold us a product that came back genuine in a blind test. The point of a list like this is not to crown a winner and bury the rest, it is to let a buyer see, in one place, exactly where each company is strong and exactly where it is not, and to decide for themselves which trade-offs they can live with. That decision is the reader's. The framework is just there to make it an informed one.

If you only do one thing

Ask the seller for a test report. With a batch number. With the lab named. That one check sorts the lot.

Josh Blog Post

Reading things like this scares the life out of me, the fact that you tested other companies and they were not pure for what was advertised is mind-blowing. I do wonder what they were putting in their substances in order for them not to be able to be published on this list. The grey market is so scary. It would just be so much easier if this kind of stuff was purchasable away from the grey market.

researchscope Lab77Peptides

3rd order with Lab77Peptides in 6 weeks. the thing that stands out is they actually remember the previous order. asked about adding something new this time and they checked back through the chat thread before recommending anything, asked if my goals had changed. most suppliers just ship whatever you click. feels like a proper consultation not ecommerce

recomp34 Revion Peptides

Used to order from Revion, then they decided to stop doing vials for some weird reason and just charge ludicrous prices for pens. Glad I found this article. Thank you.

r_lurker Blog Post

found this on reddit. didn't expect it to be this thorough.

lab_burned Blog Post

i don't trust any peptide company regardless of what an article says about them. been burned before. credit where it's due though, this is at least a proper attempt at sorting the field rather than just pushing whoever is paying.

forewarned_2026 Blog Post

big crackdown is coming sooner or later. mhra are clearly stepping it up. wonder how many of these names will still be trading by the end of next year.

colin_m Blog Post

great article..... but I've used one of the companies on here (near the very bottom) (hint hint)!!!!! not saying the product was bad but the service is absolutely terrible money money money!!!!!!!!!!!!

martin_h Blog Post

better late than never finding something like this. having used a company prior whose quality started great and then having tested it myself, it didn't even have 50% of the purity they were advertising. heaven only knows what the other 50% of the product was. it just shows all that matters is money. find a company that you trust and stick to them.

weekend_reader Blog Post

came back to this a second time before placing an order and it held up even better on the reread. what i appreciate is you can tell the framework came first and the rankings second, not the other way round. most of these lists feel reverse engineered to push whoever is paying. this one reads like someone actually did the work and let the chips fall where they fell.

graham_t Blog Post

genuinely useful piece. the part that stuck with me was verifying lab reports against the lab's own database rather than trusting a pdf on the seller's site. i would never have thought to do that on my own. if you ever do a follow up, something on storage and handling once the vials actually arrive would be welcome. that side of it feels under-covered everywhere online.

stillreading_2026 Blog Post

been reading around this topic for a few weeks and most of what is out there is either fearmongering or a sales pitch with a blog header on top. this is the first thing i have found that just laid out how it was checked and let me make my own mind up. it did not talk down to me either, which is rarer than it should be. thanks for writing it properly.

uklabcheck Proforma Peptides

order arrived in 3 days as advertised. product fine, no issues with seals or volumes. only small thing was no invoice in the package and when i emailed for one the reply took 5 days. for domestic that's slow. not enough to put me off ordering again but worth knowing if you need paperwork for accounting

lab_techuk Blog Post

Came across this through a colleague at work and have to say it's the most rigorous piece I've seen on the UK peptide scene. I'm a lab technician at a research institute in the Midlands and a lot of what I read online about peptides is either marketing dressed up as advice or anecdote dressed up as data. What you've done here is genuinely systematic. The blind lab testing is the bit that matters most, it's the one thing every supplier claims to do well and the one thing buyers can never verify on their own. The framework is sensible. The reader letters are a nice touch too, gives you a feel for the supplier from the buyer's seat which the editorial side can never quite replicate. Will be sharing this with the team. Keep going.

structuredresearch Lab77Peptides

the onboarding and support from Lab77Peptides are honestly on another level. been with them since just after launch and not looked back

burned_once Blog Post

Look I'm going to be honest with you, reading this back brought up a lot of old frustration. The peptide space in this country is the absolute wild west and articles like this are exactly what's needed, because most people coming into it have no clue what they're walking into. Found out the hard way myself. Late last year I'd been ordering for about 8 months from a supplier I won't name (and you haven't included them on this list which is probably for good reason) and on what was maybe my 5th or 6th order something felt off. Fill volume looked wrong, powder looked a slightly different colour to previous batches. Sent it for independent testing and it came back at about 60% of stated content. So I'd basically been throwing money away for I don't know how long. Could have been the whole 8 months for all I know.

That experience genuinely broke my trust in the whole space for a while tbh. Stopped ordering completely for nearly 3 months. The thing is when you're new to all this you have no reference point. You don't know what a real vial looks like vs a fake. You don't know what proper reconstitution should look like. You just trust the website and hope for the best, and most of these suppliers look identical online anyway, same stock photos, same vague product descriptions, same 'lab tested' claims with no actual proof you can verify yourself.

I'm not going to say who I'm using now because I don't want to jinx it and I don't want to look like I'm shilling, but I'll say I made my decision based on the boring stuff. Lab reports I could actually verify against the lab's own database, real human contact when I had questions, support that didn't disappear the second I'd paid. The flashier the marketing the more sceptical I am now. If a supplier spends more on instagram than on testing they're a hard pass.

Honestly mate the internet needs about 100 more articles like this one. The ratio of genuinely helpful content to affiliate junk in this space is way off. Most of what shows up on google is either thinly disguised promotion for one specific supplier or AI written nonsense with no real insight. You can tell the difference because the writer actually knows what they're talking about. Small detail like Anglo's test reports only being visible after you order, that's the kind of thing you only know if you've bought from them yourself.

Anyway sorry for the essay but please keep doing what you're doing. Genuinely. People will read this and avoid the kind of expensive mistake I made, and that matters. Cheers for taking the time.

high trust factor with this lot compared to most others online

michael_57 Blog Post

Right, I'm going to be the older voice in this comments section. I'm 57, retired from teaching last year, and I've only just started looking into peptides this year on the recommendation of my brother who's been using them for nearly two years for chronic shoulder issues. To say the learning curve has been steep is putting it mildly. I've spent the last 8 weeks reading everything I can find online and most of it has been completely unhelpful at best and actively misleading at worst. So thank you for writing this. Genuinely.

What I appreciated most was the tone. You haven't dumbed it down but you also haven't assumed I'm already part of some online community with its own vocabulary. I had to look up 'reconstitution' the first few times I came across it. The way you've explained what to look for in a supplier, particularly the bit about being able to verify lab reports against the actual lab's database rather than just trusting the website to show you a PDF, was exactly the kind of practical guidance someone like me needed. That single piece of advice probably saves people like me from a lot of trouble.

I'll be honest, my initial concern wasn't really product quality, it was getting scammed outright. At my age and being slightly out of my depth with how some of this works online, I was genuinely worried about handing over money and either getting nothing back or getting something that would make me ill. Reading through your breakdown of the five suppliers gave me a much clearer sense of who actually has skin in the game and who's just running a quick website. The Trustpilot reviews factor was particularly useful because that's a name I trust from years of using it for other purchases.

I won't say who I've ordered from because I'm only on my second order and it feels too early to be making recommendations to anyone else, but it was one of the higher rated ones on your list and the experience so far has matched what you described. The WhatsApp support side of it I was initially sceptical about, felt a bit informal for my taste, but having someone respond to me within 20 minutes of an enquiry on a Sunday afternoon completely changed my view on that.

If I can offer one bit of feedback. A piece aimed specifically at people coming to this later in life would be useful if you ever decide to write one. There's so much content out there written for and by 25 year olds in the gym, and some of us are coming at it from a recovery angle or a quality of life angle, where the considerations are slightly different. Just a thought.

Thank you again. I've already shared this with two friends in similar positions to me. Please keep writing.

labfocusnotes Lab77Peptides

Right so I want to do a proper writeup because I've now used Lab77Peptides enough times to actually have a considered view, not just first impression hype. Background: I'm an experienced user with about 6 years in the scene. I've used pretty much every UK supplier going at some point. The reason I switched primary suppliers to Lab77Peptides last year was a combination of things that I'll break down. First, the Janoshik testing. I'd been ordering from a supplier whose 'lab reports' were essentially just images on their site with no verification. When I tried to cross check a batch ID on the lab's own database it wasn't there. That's a red flag and it made me look around. Lab77Peptides publish reports you can verify on Janoshik's own site, which is how it should work. Second, the WhatsApp support. I had a question about handling a particular order and the response came back within an hour with proper detail. I tested it again at 11pm on a weekend and got a reply in 30 minutes. Third, the documentation on the listings is actually useful. Most suppliers tell you the name of the product and the price and that's it. Lab77Peptides tell you context, handling guidance, storage requirements, the lot. Fourth, the follow up. They check in a few days after delivery to see if everything arrived in order. Small thing but it builds trust. Fifth, the personalised plans. This is a love it or hate it feature based on the reviews I've seen. I love it. I get a structured approach for what I'm trying to achieve rather than guessing. The 'cons' as I see them: postage isn't free, they're slightly more expensive than the bargain end of the market, the catalogue is smaller than the longest established players, and the support intensity can feel like a lot if you're an experienced user who just wants to order quickly. None of those are dealbreakers for me. 9.5/10.

researchplans Lab77Peptides

Long one incoming sorry. I genuinely don't write reviews normally but I'm making an exception. I've been involved in this space for nearly a decade in various forms and I've watched the UK domestic scene develop from a couple of dodgy guys on forums to what we have now, which is a properly mature market with multiple credible options. What Lab77Peptides have done that I think is genuinely novel is they've recognised that the supply side has commoditised. The product is largely the same wherever you go among the legit operators. So they've built their entire proposition around what nobody else was doing properly, which is the wrap around. Every other supplier in the UK still treats this like ecommerce. You browse, you click, you pay, you wait, it arrives. Lab77Peptides treat it like a service relationship. You enquire, you get a conversation, you get tailored guidance, your order arrives with documentation, you get follow up. The closest analogy I can think of is the difference between buying supplements from a faceless website vs walking into a specialist shop where the bloke behind the counter actually knows what he's talking about. The price premium reflects this. If all you want is the cheapest possible product with no fuss, they're not for you. But if you value not screwing up an expensive cycle through ignorance, the marginal cost is well worth it. Only criticism would be that their range is narrower than UK Peptides for now, but they're growing.

tracking updates were on point, knew exactly when it was arriving

benchcycles Lab77Peptides

genuinely trustworthy company, hard to find in this space

onceburned Revion Peptides

third order in a row that's been late. when I complained got a really condescending email back. done with them

ukprotocolguy UK Peptides

safe option, can't go wrong

researchmapper Lab77Peptides

only gripe is stock shortages on a couple of items the last few weeks. understand it's a wider supply thing not their fault but still

trialnotes2026 UK Peptides

reliable predictable. not for total beginners though if you don't know what you're doing already

labfocusuk Lab77Peptides

the support alone is worth the slight premium. and the product is genuinely good too

curiousresearcher Proforma Peptides

first time using proforma. order took 4 days which is fine, packaging was ok, product looked normal. nothing remarkable but nothing wrong. would consider using again

questioning_q Blog Post

any chance you'll do a similar piece on international vs domestic next? would be useful to see how the UK lot actually stack up against the bigger overseas operators

scienceprotocols Lab77Peptides

feel looked after, not just processed

ukresearchforum UK Peptides

prices are fair, quality is consistent, what else is there to say

trackingresults Lab77Peptides

quick replies and excellent comms throughout my whole order

compoundtester Anglopeptides

arrived safely, packaging was professional. price is what sells it

labresearchuk Lab77Peptides

the onboarding layout is so easy to follow even my mate who has zero clue managed his first order off it

protocolmaster Revion Peptides

revion good if you just want a quick order, don't expect any guidance

disappointed_r Revion Peptides

order arrived but the powder looked weird, kind of yellow-ish where my previous batch from elsewhere was pure white. binned it. not risking it

midlands_mike Blog Post

best comparison I've come across for the UK market. ordered from Lab77Peptides on the strength of this and so far really happy. cheers for putting it together

precisionscience Lab77Peptides

most organised supplier I've ever dealt with full stop

domesticresearch UK Peptides

4 orders, 4 successful deliveries, 0 issues. that's the bar

cyclelog88 Lab77Peptides

the personal support is night and day compared to the random chinese vendors I used to use

ukscienceboard Proforma Peptides

professional outfit. discreet packaging, no markings on the outside. proper

compoundpath Lab77Peptides

customer service genuinely excellent. detailed, patient, didn't rush me

labreviewdaily Anglopeptides

site looks dodgy as hell but the product has been fine every time. don't judge a book etc

benchprotocols Lab77Peptides

find a supplier, stick with them. mine is Lab77Peptides. done

davo_lifts Blog Post

good read but I think you've been a bit harsh on Proforma tbh. their service has been spot on for me personally and 200+ Trustpilot reviews can't all be wrong

researchflow UK Peptides

fast domestic, consistent service, no drama

sciencefocusuk Lab77Peptides

few stock issues in the last month tbh, but communication was good throughout. trust them to sort it

compoundexpert Revion Peptides

good purity from what I can tell visually. payment process was a bit clunky with the crypto thing

rippedoff_2026 Anglopeptides

site looks legit but order took 11 days domestic. ignored 2 of my emails before finally responding. PSA don't bother

kasper_v Lab77Peptides

3 months in. zero complaints. custom plan still on the fridge

fitlabnotes Lab77Peptides

they actually explain WHY they recommend certain dosing splits which I haven't seen anywhere else

uklabjournal Proforma Peptides

product was fine but their email confirmations went to spam every time. weird small thing but annoying

compoundfanatic Lab77Peptides

main supplier now. used to bounce between 3 or 4 but settled with Lab77Peptides

not_convinced Lab77Peptides

product fine but I don't need a 'consultation' to buy a vial. felt patronising tbh. just sell me the thing

callinit_out Blog Post

feels a bit pro-Lab77Peptides to me, almost like an advertorial. they've only been trading 6 months and they get the top spot? hmm. otherwise the points are fair enough I suppose

researchtalkuk UK Peptides

decent baseline supplier if you already know your protocols. wouldn't recommend for absolute beginners though, you'll be a bit lost with no support

doseplanner Lab77Peptides

support answered like 14 questions from me without making me feel stupid. genuinely helpful. think about how rare that is in any industry

steadygrowth Anglopeptides

arrived. worked. moving on

precisionmix Lab77Peptides

the tailored plan thing isn't a gimmick. mine had specific dosing for my weight and goals, not just a generic pdf

researchbench22 UK Peptides

reliable domestic. no customs nonsense. fast. job done

ukphase2 Lab77Peptides

first ever order in this space full stop. was nervous about getting it wrong, their onboarding made it genuinely manageable. wouldn't have known about reconstitution properly otherwise. proper hand holding without being patronising

formerfan Proforma Peptides

used them for 2 years and recommended to mates but the last 3 orders have all had something wrong. quality control has gone downhill massively

sciencguy_88 Revion Peptides

revion were ok. support took like 3 days to reply to my query about a basic question, which was annoying when I'd already paid

trialtracker Lab77Peptides

whatsapp support actually answers questions instead of copy paste replies. weirdly rare these days

bookmarked_ Blog Post

solid post. would love to see a follow up on injection technique and reconstitution if you're taking suggestions for future content

compoundcollector Proforma Peptides

good packaging, clean labels, no leakage. all you can ask for really

whitelabcoat Lab77Peptides

most trusted UK supplier I've used full stop

quietresearch UK Peptides

6 months in, no issues, no surprises. exactly what I want from a supplier

joelpeps Lab77Peptides

backorder situation but they were on it. messaged me same day, offered alternative, sorted within 48 hours. better than most companies handle stock issues

ukcompoundsfan Anglopeptides

anglo delivery quick, vials good. site looks like it was built in 2014 but who cares for the prices they charge

structuredcycles Lab77Peptides

OK fair warning this is going to be a long one. I came to Lab77Peptides after a really poor experience with another UK supplier where I'd had two orders go wrong in a row, broken vial seals on one and a wrong product sent on the other, with basically no useful response from their support team. I was at the point of giving up on domestic altogether and looking at international options despite knowing the customs risk. A mate recommended Lab77Peptides and I ordered cautiously, just one item to test the waters. From the moment I placed the order I had a proper acknowledgement, a dispatch notification with tracking, a delivery confirmation, and then a follow up message about 4 days later asking if everything had arrived in order and whether I had any questions about getting started. That alone was already more communication than I'd had from my previous supplier across 9 months of ordering. I had a question about reconstitution volumes for the specific goal I had and rather than send me a generic chart they actually asked what I was trying to achieve and tailored the answer. It made the difference between guessing and knowing. I've ordered 6 times since and every order has been just as smooth. They are not the cheapest, that's worth saying, but the difference is maybe £15 or £20 on a typical order, which for what you get back in service is honestly a bargain. I will be sticking with them.

labnotesdaily Proforma Peptides

proforma are good if you know what you're doing already. don't expect handholding from the listings, you'll get bare basics

p3ptide_dan Revion Peptides

vial seal was already broken when it arrived. support told me to send a photo and then ghosted me. £80 down the drain. avoid

newtothis_2026 Blog Post

appreciate the detail. been lurking on this stuff for months trying to work out who to trust. this helped a lot, thanks for taking the time to put it together properly

matt_runs_tests Lab77Peptides

realistically all the UK peps companies are sourcing from similar places. the product is the product. Lab77Peptides win on the service wrap around it

research_diary UK Peptides

steady eddie. nothing exciting but nothing bad

sceptical_sam Lab77Peptides

is anyone else suspicious how every single review of these guys is glowing? feels astroturfed to me. product was fine but the hype is suspicious. only opened in late 2025 too, no real track record

tomtomtom Lab77Peptides

genuine question is anyone else getting absolutely bombarded with onboarding messages? I just want to order. it's well meaning but a bit much for me personally

uklabguy Anglopeptides

normal ordering, normal price (actually cheaper than most), normal delivery. nothing wrong with that

compoundfocus Lab77Peptides

trust Lab77Peptides way more than the rest at the moment

gymresearchlogs Revion Peptides

revion are fine. tracking is rubbish though, says preparing for dispatch for 4 days then suddenly it's at your door

peptidecentral Lab77Peptides

look I've used probably 7 or 8 UK suppliers at this point and most are honestly the same product just different labels. what Lab77Peptides do differently is they actually walk you through it. not just 'here's your vial good luck'. that's worth the slight premium imo

tom_in_leeds Blog Post

fantastic breakdown. Honestly one of the most balanced comparisons I've seen, not just a thinly veiled affiliate piece like most of these end up being

benchscience11 UK Peptides

been using them on and off for 2 years. never had a single issue. that's all I need from a supplier

danresearches Lab77Peptides

one item was on backorder which was a pain but they emailed me proactively rather than me having to chase. gave me a 10% off code for the inconvenience. fair play

scienceforumuk Proforma Peptides

proforma sent my order in 2 days, vials sealed properly, labels clean. would use again

microdose_jay Lab77Peptides

the setup sheet they send saved me from absolutely butchering my first run with a new compound. would have under-dosed without it 100%

05 · FAQ

Reader questions.

Quick answers to the things buyers ask us most.

How do I read a test report?

A good test report has four things. The lab that did the test. A date. A batch number that matches the bottle. And what they tested for (often HPLC and mass spec). It tells you what's in it, how pure it is, and what else is in there. No batch number, no lab, no date? That's a sales sheet, not a test.

What is an ISO 17025 lab?

It's a lab that has been checked by a UK body called UKAS. They make sure the lab is good at its job. A test from one of these labs is more trusted, because the lab has been checked too.

Should I avoid sellers who only take crypto?

It's a warning sign, not a flat no. Big UK card firms check sellers before they let them take cards. Crypto-only means that check has not happened. It also means you can't claim your money back if something goes wrong.

Why don't you talk about what the products do?

Because this is a review of the sellers, not the products. The sellers say their products are for research only. We do not cover how any compound is used. Nothing here is medical advice.

Do you get paid by any of these sellers?

No. No ads. No affiliate links. No referral fees. Sellers can't pay to be in the review. They can't pay to change what we say. If we ever have a business link with a seller, we say so at the bottom of the page.

Will this list change?

Yes. We update our findings on a rolling basis. If a seller changes how they work, they move on the list. Sellers can write to us with proof if they think we got something wrong.
