As of 2026-11-08. Lab tests published counts every certificate on the platform; the COA benchmarks count a smaller set, single vials only.
Peptigrity is an independent peptide shop review platform that publishes buyer reviews, third-party lab test results, Trust Scores and per-milligram prices for peptide shops, and runs a peptide forum where those records are discussed. The platform tracks 1,078 shops across 118 peptides, with 14,430 lab tests published as of 2026-11-08.
Peptigrity operates independently from every shop, manufacturer, and testing laboratory in its database. It carries no affiliate links, and listing and claiming are free for shops and labs. Links to a shop's website pass through peptigrity.com/go/ so we can count how many buyers we send each shop; they carry no affiliate code and earn no commission. No shop pays to modify its score, boost its ranking, or suppress negative reviews.
Buyers and shops read the same public record, and no shop can edit or remove the reviews or lab results on it. Shops can claim their page for free to reply to reviews, post on their own board and keep their details current, and testing labs can claim theirs to answer questions and keep their stated facts current. Claiming changes nothing about a Trust Score, a ranking or which reviews are shown.
The research peptide market operates outside pharmaceutical regulation. In the grey market for peptides, nobody between the factory and the buyer is answerable for a batch, so a vial's label and a lab's certificate of analysis (COA) are the only evidence of what the vial holds. Even on the certificates shops choose to publish, Peptigrity's COA benchmarks find that about 1 in 15 single-vial certificates (6.8%) measured less than 95% of the labeled amount, while fewer than 1 in 300 (0.28%) showed under 95% purity (verified October 2026).
Peptigrity addresses 3 specific problems in the peptide market:
Peptigrity provides 9 resources for peptide buyers, all free to use:
Every listed shop, ranked by Trust Score or grouped by when a third-party lab last tested it, with filters by shipping region.
Third-party HPLC certificates, searchable by compound, shop or lab, each labeled by who sourced the vial and published whatever the result.
A lot-number lookup: type the code printed on your vial to see every certificate on file for that lot, what the lab measured against the label, and whether the lab's own portal confirms the report.
Shop talk, lab results, testing help and scam watch, open to read without an account. Criticism of a shop stays up, and every moderation action is published on a public log.
Per-milligram prices read automatically from the public storefronts of shops with third-party lab tests on file, each with the date it was read. Prices exclude shipping, taxes and customs, and the lowest figure is often a bulk vial.
A page for every compound tracked: what it is, how it works and what it is approved for where that applies, with any lab tests on file and the shops that list it.
Independent peptide testing laboratories, each with the tests it has run and, where the lab states them, its methods and prices. Peptigrity accredits, endorses and ranks none of them.
Calculators that turn a vial size and a water volume into syringe units, a testing planner that matches your question to a test and a lab, and a peptide tracker that checks your vial's lot against certificates on file.
Research-backed guides on peptide quality verification, compound profiles, and harm reduction.
The Trust Score is a number from 0 to 100 shown on every shop page that has reviews or lab tests on file. As of October 2026 it combines 2 equally weighted data sources, and each one counts for more as the data behind it grows:
Objective purity data and subjective buyer experience are treated as equally important signals. Because each channel is weighted by its own volume, a shop needs both buyer reviews and lab tests to reach the top of the ranking. Claiming a page, posting promotions, moderation and karma never enter the score.
Shops with at least one published lab test carry a “Tests on file” label; shops with reviews but no lab tests carry “Reviews only”, and shops with neither carry “Provisional”. A label says what is on record, not how good the shop is. The full formula, its smoothing constants and every change to it are set out on How Peptigrity actually works, the platform's methodology page.
Peptigrity is founder-run and independent, and has operated since 2024. A developer maintains the platform, and staff post on the forum as @Peptigrity, marked with a Staff badge. The platform is not affiliated with any peptide shop, manufacturer, testing laboratory, or pharmaceutical company. Peptigrity does not sell peptides, does not run a laboratory, and does not recommend doses or vendors.
