Open peptide vendor directory

A listing is a claim, not a verdict

Every company on this page put itself here. A submission is written by the company, reviewed by a moderator for accuracy and category fit, and published — nothing about that process measures whether the vendor is any good. It confirms the business exists, sells what it says it sells, and has a working address on the open web. Read a directory entry the way you would read a company's own about page, because that is what it is.

The judgement lives one page over. /vendors carries the ranked reviews — scored on pricing, COA practice, shipping and ordering experience, with the methodology published alongside the table. A company can appear in this directory and be absent from those rankings, and the reverse is just as common. Neither position implies the other.

What a submission has to include

Four fields are mandatory and the form will not submit without them: the company name, a reachable website URL, a contact email that accepts mail, and at least one product category. Everything else — description, logo, country or region, and the specific peptides a company wants surfaced on its profile — is optional, and a listing that skips them renders as a thinner page.

Submissions land in a pending state. Only a moderator can move a listing to approved, and until that happens it is invisible to everyone except its owner — the database enforces that directly rather than trusting the application layer. Listings are free during the founding period and move to a flat annual fee afterwards, and a listing can be updated or withdrawn at any time on request.

Checking a company before you order

Directory presence is worth very little on its own. These are the checks that separate a real supplier from a confident one, in the order they are worth doing:

• Match the COA to the vial in your hand. A certificate is only evidence if its batch number matches the lot printed on the label. A single certificate reused across every product is a marketing asset, not a test result.
• Look for the identity test, not just purity. An HPLC purity figure says how much of the vial is one compound. Mass spectrometry says whether that compound is the one on the label. Both belong on the certificate.
• Check the certificate is dated and signed. No analysis date, no analyst, or no lab name means the document cannot be traced back to anyone.
• Confirm where it ships from. Shipping origin sets customs exposure and transit time, and a vendor that will not state it plainly is telling you something.
• Compare per milligram, not per vial. A cheaper vial is routinely the more expensive compound once you divide by the mass inside it.
• Place a small first order. The behaviour worth testing — packaging, cold-chain handling, transit time, and what support does when something arrives wrong — cannot be read off a website.

What the directory holds today

3 approved listings, shipping from United States, across 4 categories: Aesthetics / topicals, Blends & stacks, Single peptides, Tissue repair. That is a small directory and it is stated plainly rather than padded — every entry here was submitted and reviewed rather than scraped, and the count only moves when a real company asks to be added.
