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.

The certificate we opened is an ILS Laboratories report (COA-2026-413074, lot BPC10005, 10.7mg vs 10mg) with an ILS access code — while the certifications page credits Freedom Diagnostics.
