Cosmetic peptides

Every lot, including GHK-Cu (Copper Peptide), PT-141, Melanotan 2, is assayed by reverse-phase HPLC-UV for purity and confirmed by LC-MS, then ships with a certificate of analysis matched to the batch number printed on the vial. Look up any batch on the Verify COA page before you buy, and independent third-party testing of any lot is available on request.

Orders ship in plain, unmarked packaging from within the US, fully tracked, with next business day dispatch once payment clears. Card payments are handled by Stripe and show a neutral name on your statement. If a package is lost, held, damaged or wrong, our delivery guarantee reships or refunds it, no dispute needed.

They are supplied lyophilized, generally kept frozen before reconstitution and refrigerated once in solution, within each compound stability window. Reconstitute with bacteriostatic water in a laboratory setting; our free reconstitution calculator works out the concentration and syringe draw for any vial size.
