All research peptides

Every lot is assayed by reverse-phase HPLC-UV for purity and confirmed by LC-MS for identity, 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 our guide on how to read a COA explains what the purity and mass-spec results mean.

Orders ship in plain, unmarked packaging from within the US, fully tracked, dispatched the next business day after payment clears, with 2 business day delivery once on the way. 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.

Compounds are supplied lyophilized, generally kept frozen before reconstitution and refrigerated once in solution. Reconstitute with bacteriostatic water in a laboratory setting; our free reconstitution calculator works out the concentration and syringe draw for any vial size, and the storage guide covers shelf life before and after reconstitution.

Checkout is by card, processed securely by Stripe. Your full card number never touches our servers, and the charge shows a neutral descriptor on your statement.
