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.
Peptira: Trustpilot profile REMOVED (read 19 Sep 2026; a third-party read on 18 Sep showed 4.5 across 244 reviews, so the removal is recent). Legal entity is Peptira LLC but the only address published is a P.O. Box (Chadron, NE 69337) — no street address. The 61-peptide catalog sits beside pressed raws and 'other' categories; check what you are buying.
