RANKED BY REGULATOR RECORDS · UPDATED OCTOBER 24, 2026
Verified peptide suppliers
97 of 149 peptide manufacturers and CDMOs in the directory clear every check below. 78 have a GMP record with a regulator; 19 more are established research-grade synthesis houses. Order comes from the evidence on each profile, not from reviews or opinion.
Every company in the regional lists has a GMP record with a regulator and no FDA warning letter or import alert in the last five years. Within each region, a higher score ranks first, then more peptide APIs with an active US Drug Master File.

How this list is built
It starts from every listing classed as a manufacturer or CDMO (149 today). A company is removed if its website is offline (5) or it has an open FDA action or a warning letter or import alert in the last five years (8). The rest need a High confidence score (90+), which takes either a GMP record with a regulator or an established company, as set out on the scoring page.
Companies with a regulator GMP record go in the first table; established companies without one go in the second. Within each table, a higher score and more peptide APIs with active US DMFs rank first. DMF counts come from the FDA's quarterly Drug Master File list; see peptide API manufacturers by molecule.
A company missing from the list may simply be missing evidence we can check. If you make peptides and hold a regulator GMP record, submit or update your listing.
Frequently asked questions
Can a supplier pay to be on this list or move up it?
No. Inclusion and order come only from the regulator records and company facts on each profile. Paid Verified reviews, featured slots and ads on the rest of the site have no effect here, and there are no affiliate links or discount codes on this page.
Why isn't my research peptide vendor on this list?
This list covers manufacturers and CDMOs, the companies that make peptides at GMP or research scale. Retail research-peptide sellers are scored on a separate rubric built around lot-level lab reports, and you can compare them in the main directory.
What counts as a GMP record here?
An FDA inspection, a EudraGMDP certificate, or a certificate from a named regulator such as PMDA, MFDS or NMPA. "cGMP facility" wording on a company's own website does not count.
Does a US DMF mean the FDA approved the manufacturer?
No. A Drug Master File lets a finished-drug applicant reference the manufacturer's data. It shows the company has documented a peptide API for the US market, not that the FDA approved it. Many CDMOs file under their clients' programs, so a missing DMF does not keep a company off the list.
How often is the list updated?
It is rebuilt from the directory every time a profile changes, and DMF counts follow the FDA's quarterly Drug Master File list. A new FDA warning letter or import alert removes a company from the list on the next update.
