Optima Chemical Supply is a research peptide vendor - also called a supplier or source - indexed on PeptideScouter. Prices below are refreshed daily.
Optima Chemical Supply sells as Optima Supply from its own storefront at optimasupply.is and lists an address in Milwaukee, Wisconsin. The catalog spans the common research categories, including experimental compounds, from incretin agonists such as retatrutide and tirzepatide to repair peptides like BPC-157 and TB-500, along with blends, capsules and tablets. The vendor states every batch is tested by independent third-party labs, each vial carries a QR code linking to its batch certificates, and products are labeled with the milligram content measured in testing rather than a rounded figure. Its on-site lab-results library shows the reports on file per product. Purity reports cover most, while endotoxin, heavy-metal and sterility reports are posted for some. Unused items in intact original packaging can be returned within 30 days of purchase, with a free return label, and defective or damaged items are replaced. Shipping is free on orders over $300.
