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.
Global Aminos: The lab (Freedom Diagnostics) appears only on the certificate image, never in page text; the certificate carries a search code (Glob2604060054) and reports 10.31mg vs 10mg label. No legal entity, address or phone. GLP products sold as GLP-S (1) / GLP-T (2) / GLP-R (3) with no stated identity, and one page describes its GLP product as an 'antagonist'. 38 reviews.
