Caveats
Purgo Labs: Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Everest Peptides: 45 Trustpilot reviews — below our 50 threshold for an independent review base. Certificates are vendor-hosted PDFs, not verifiable at the lab. No street address or phone anywhere on the site. Tirzepatide and retatrutide are sold as 'GLP-2 TRZ' and 'GLP-3 RT' with only a CAS number to identify them. Promotional banners and 'researcher count' claims differ from page to page.
