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.
Purus Peptides: The site says every product is 'certified by Janoshik', but the acetic-acid and bacteriostatic-water certificates in its own library — labelled 'Tested by Janoshik' — are issued by Vanguard Laboratory. 26 reviews. No legal entity or street address; a phone number appears in the footer but not on the Contact page. Sells HCG. No standalone TB-500. GLP products sold as PP-2T / PP-3R with no stated identity. The BPC-157 report shows 98.2% purity.
