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.
EZ Peptides: Trustpilot profile REMOVED. Semaglutide, tirzepatide and retatrutide are sold as EZP-1P / EZP-2P / EZP-3P with no stated identity on the page — only older certificate labels reveal it. 'TB-500 Frag 17-23' is a fragment, not full-length TB-500 (a separate TB4 product exists at $68). Age gate says 21+, Terms say 18+. 'Pay with crypto, save 10%'.
