Independent peptide review platform · Est. 2024 · No ads · No sponsors · No affiliates

Peptide supplier reviews, lab tests and prices you can check yourself.

Peptigrity is an independent peptide verification platform. We publish 13,474 third-party HPLC lab tests, 947 buyer reviews and daily-read prices across 766 peptide shops shipping to the US, Europe, the UK, Canada and Australia, and we run a peptide forum where buyers compare notes. Every shop gets a trust score it cannot pay to change. We don't sell peptides — we verify them.

As of 2026-10-16. This is the number of certificates published on the platform. The Purity Index reports a smaller indexed figure — the subset that meets its inclusion rules (at least five tests per compound, recency-weighted).

Who Peptigrity is for

two sides of one record

Peptigrity serves the people who buy research peptides and the shops that sell them. Both read the same public record; neither can edit it.

Buyers and researchers

Check a shop before you pay

Find a shop's trust score, its third-party purity results and what other buyers experienced, then compare its prices per milligram against the market.

  • Look a shop up, or browse the ranking
  • Check the lot number on your vial against a COA on file
  • Ask the forum when the record is thin

Peptide shops

Claim your page, show your tests

Claim your listing through your shop's official email, upload lab tests and price lists, answer buyers on your shop board, and embed a badge that states facts about your record — never an endorsement.

  • Claiming is free; so is listing
  • Tests you submit are marked as shop-provided
  • No shop can pay to change its score

Top-rated peptide suppliers by Trust Score

recomputed when new data lands · last 16 Oct 2026, 08:42 UTCBrowse all 766 shops →

The trust score is a number from 0 to 100 on every shop page. Half of it is the average HPLC purity from independent lab tests; the other half is the average of buyer reviews. Lab verified means the shop has at least one third-party test on file; a shop with reviews but no tests is marked Reviews only, so you can see what the score rests on. “Ships from” is what a shop states about its warehouses — it is recorded, not verified.

Peptide suppliers by shipping region

where the shops dispatch from and ship toFilter shops by region →

Peptide buyers are everywhere; the shops are not. Most tested shops dispatch from the United States, a smaller group from the EU and the UK, and a growing number ship direct from China. Where a shop dispatches from decides customs exposure, delivery time and whether a seized parcel is reshipped — so the region is a first filter, not a footnote. Regions are what shops state about their warehouses; shops that have not stated one appear in the last cell.

Latest peptide lab tests (HPLC)

13,474 on file · 225 shops tested in the last 6 monthsAll lab tests →

An HPLC purity figure says how much of what is in the vial is the stated peptide; 99% or above is the usual pass mark for a research-grade vial, and anything under 95% is a reason to ask questions. Tests reach Peptigrity three ways: buyers send a vial to an independent lab and submit the certificate, shops submit their own (marked as shop-provided), and we collect published certificates from shop and lab websites. Every result is published, whatever it shows — a failed test stays on the shop's record next to the passes.

The independent labs behind these results

All testing labs → · Compare lab prices →

Peptigrity does not run a lab. Every purity figure on the site traces to a certificate from an independent laboratory, and each lab has its own page with the tests it has run, its stated methods and its prices. These are the labs that appear most often in the record.

Check your vial, compare the price

two tools buyers use before and after ordering

Check your vial's lot number

A certificate of analysis is only worth something if it matches the vial in your hand. Type the lot or batch number printed on your vial and Peptigrity shows every COA on file for that lot — which lab ran it, the purity it found and the shop it came from — or tells you plainly that no certificate is on file.

Peptide prices, read daily

Per-milligram prices are read from public storefronts every day, only from shops that have third-party lab tests on file, and shown with the vial size so you compare like with like. Promotions are posted by claimed shops themselves and never change a ranking.

Most-tested peptides

118 compounds · purity across brands, prices and a guide for eachAll peptides →

Every compound page gathers what the record says about one peptide: average HPLC purity across every tested brand, which shops stock it and at what price per milligram, and a plain-language guide to what it is and what it is approved for, where that applies. The 8 below carry the most lab tests on file.

Recent peptide supplier reviews

947 on fileAll reviews → ·

Reviews on Peptigrity come from registered buyers and rate four things separately — product quality, delivery, customer service and price — so a five-star delivery does not hide a two-star product. Reviews are still scarce in this market, so read a review together with the shop's lab record rather than on its own; photos of the vial received and the lot number are the proof that carries most weight. Shops cannot remove or reorder reviews.

Peptide forum

shop talk, lab results, prices, protocols · no vendor money, no censorship of criticismAll discussions →

The forum is where the record gets discussed: a shop that stopped answering, a lab result that looks off, what people are paying for a compound this month. It is open to read without an account, flat rather than split into sub-forums — the boards below are filters on one stream — and moderated only for spam and impersonation; criticism of a shop stays up. Threads link straight to the shop pages, lab tests and prices they talk about.

How Peptigrity works, and who built it

What Peptigrity is

Peptigrity is an independent peptide shop review platform. It publishes community-submitted reviews, third-party HPLC lab test results and trust scores for peptide shops, and runs the forum where those records are discussed. It operates independently from every shop, manufacturer and testing laboratory in its database: no advertising, no sponsorship, no affiliate commissions, no paid placement. No shop pays to modify its score, boost its ranking or suppress a review. Outbound links to shops carry no affiliate or tracking parameters.

Why it exists

The research peptide market operates outside pharmaceutical regulation — a grey market in the literal sense — and independent re-testing has repeatedly found that a meaningful share of supplier-provided certificates overstate purity, misidentify the compound or carry fabricated batch numbers. Peptigrity addresses three problems that follow from that:

  1. Unverified quality claims. Shops publish their own purity numbers. Peptigrity aggregates results from independent laboratories, submitted by buyers and collected from public certificates, and marks shop-provided tests as such.
  2. Fragmented buyer feedback. Experiences are scattered across Reddit, Telegram and forum posts that are hard to search. Peptigrity consolidates them into one structured profile per shop with sub-ratings for quality, delivery, service and price.
  3. No accountability for mislabeling. A shop selling underdosed or impure product faces no public consequence unless buyers share results. Peptigrity publishes every lab result, whatever it shows, as a permanent record on the shop's page.

How a trust score is built

Two equally weighted sources: the average of community reviews (50%) and the average HPLC purity from independent tests (50%). Objective purity data and subjective buyer experience are treated as equally important. Shops with tests on file are marked Lab verified; shops with reviews but no tests are marked Reviews only. Scores recompute whenever a new review or test lands. The full rules, including how supplier-provided certificates are handled, are on the methodology page.

01

Community reviews

Registered buyers rate quality, delivery, service and price; lot numbers and vial photos encouraged.

02

Independent lab tests

Third-party HPLC certificates, each linked to the lab that ran it and the shop it came from.

03

Trust scores

Reviews 50% + lab purity 50%. Recomputed on new data. No shop can pay to change it.

04

Open record

Methodology published, the Purity Index as the public purity statistic, crawl policy public, data open to researchers and AI assistants via llms.txt.
