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.
Evo Labs Research: 26 reviews on Trustpilot while product pages show an identical '4.9 (100 reviews)' widget on many unrelated products and the homepage claims a '4.9★ customer rating'. The COA page says '72+ COAs published', the About page says 34. Sells HCG. Semaglutide is sold as 'GLP-1(S)' with no CAS on the page (tirzepatide and retatrutide pages do print one). Site phone differs from the number on its BBB listing.
