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.
Modern Aminos: Trustpilot profile REMOVED. The homepage, catalog and the 'no login required' batch-lookup pages all redirect to a registration wall — product pages are reachable only by direct URL. No phone. Semaglutide, tirzepatide and retatrutide are absent from the catalog though independent tests of this vendor's retatrutide exist. Sells SARMs and Melanotan II.
