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.
Glacier Aminos: The lab (Ethos Analytics) is identifiable only from the certificate's sample ID and signatory, never in page text; the certificate (lot BPC10GA-06) reports 10.08 / 10.14mg vs 10mg label but offers no lab-side lookup. Storefront hides prices behind account creation. No semaglutide, tirzepatide or retatrutide. Domain is about 13 months old.
