Vendor status
Closed peptide vendors
Closed peptide vendors and shops that went offline: 29 lab-tested shops that were deactivated, stopped listing products, reported payment problems or no longer have a working website.
- Each status is quoted from its source: Finnrick's vendor listing, or our own check of the shop's website on Oct 14, 2026.
- “No working storefront” is not the same as closed. Some shops sell through messaging apps, and 10 of these had a sample tested in the last 60 days.
- Each row names a shop whose samples of the same peptide graded A or B.
