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.
Glow Aminos: Catalog, prices, certificates, lab name and company identity are all behind registration, which we do not do. Trustpilot is 4.3 across 10 reviews, unclaimed — far below our 50-review threshold. The gate and template are identical to Flawless Compounds, which suggests a shared operator. Scored on what is public: almost nothing.
