Independent supplier index

Verified reviews of peptide suppliers, scored 0–100.

Every supplier is measured on five weighted categories — price, delivery speed, product effectiveness, communication and packaging. No stars, no sponsored placement.

Read this first. Peptides listed on this site are research chemicals. Nothing here is medical advice, an endorsement, or a recommendation to use any compound. Peptide Pilot sells nothing and takes no vendor money.

01 · Unfiltered reality

Sold as “research chemicals only”, bought as something else

Virtually every peptide on the market is sold under a research-use-only designation. These products have not gone through the approval process that governs consumer medicines, and in most jurisdictions they are not legal to sell for human use. That designation has not stopped a very large number of people from buying them anyway. Pretending otherwise helps no one. Because the category sits outside normal regulation, there is no authority tracking the legal landscape, regulatory shifts, exit scams, under-dosed batches or plainly false marketing claims. That gap is the reason this site exists: a transparent, public watchdog rather than a storefront.

02 · Supply chain transparency

Almost all raw material originates in China

Whether a vendor synthesises, lyophilises or simply bottles domestically in the US, UK or EU, the underlying active pharmaceutical ingredient overwhelmingly originates from Chinese manufacturers. “Made in the USA” on a label usually describes the final fill-and-finish step, not the origin of the molecule. This is not automatically a mark against a supplier — several Chinese facilities produce excellent material — but it does mean a flag on a vial tells you nothing about purity. Independent batch verification is the only measure of safety and purity that carries real weight.

03 · Our verification mission

We check COAs against the labs that issued them

A certificate of analysis is a PDF, and PDFs are trivially edited, recycled across unrelated batches, or invented outright. Peptide Pilot contacts independent analytical testing laboratories — Janoshik, MZ Biolabs and others — to confirm that a report a vendor publishes matches an actual record on file at that lab, for that batch, on that date. When a report cannot be matched, the supplier's verification badge is withheld and the discrepancy is recorded on their profile. Verified reporting raises a supplier's standing here; falsified reporting is published.
