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.
AMC Essentials: No testing laboratory is named anywhere we could find — the site says 'Independent Labs' and 'Verifiable Certificates' without saying who. No legal entity or street address on Our Company, Contact or Terms. GLP-class products are sold as AMC-1S, AMC-2T and AMC-3R with no stated identity or CAS number, so they are excluded from our Price Index.
