Oneday Compounds is a research peptide vendor - also called a supplier or source - indexed on PeptideScouter. Prices below are refreshed daily.
Oneday Compounds sells from its own storefront at onedaycompounds.com, which requires an account to view products and prices, and lists an address in Ogden, Utah. The catalog spans the common research categories, from incretin agonists such as retatrutide and tirzepatide, sold under in-house OC- product codes, to repair peptides like BPC-157 and TB-500, along with blends, sprays, capsules and reconstitution solution. The vendor states every lot is tested before release by an independent US lab accredited to ISO/IEC 17025, on a seven-point panel covering identity, net content, purity, multi-vial conformity, sterility, endotoxins and heavy metals. Its on-site COA library is searchable by lot number and keeps certificates for sold-out earlier lots alongside the lot currently shipping. All sales are final. A damaged or incorrect item reported with photos within 7 days of delivery may be replaced, and no refunds are issued. Free US shipping applies to orders of $250 or more after discounts.
