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.
Optima Supply: Trustpilot profile removed for guideline violations (read 5 Sep 2026) — no independent review base exists, and the site still displays a review badge without disclosing the removal. BPC-157 10mg is $85 on its product page and $55 on the homepage. Lot-to-vial matching relies on a vendor-stated QR system we could not verify; many basket reports are vendor-hosted PDFs.
