From a small clean-room suite in Gilbert, Arizona, Oath Peptides began with one non-negotiable pledge: every peptide must meet the highest benchmark of purity—then prove it through USA-based verification. We source pharma-grade amino acids, synthesize under ISO-certified protocols, and validate each lot using orthogonal analytical HPLC paired with mass spectrometry to confirm both purity and molecular identity. Independent U.S. laboratories also verify the actual fill amount, ensuring that every vial contains the stated milligram quantity or more.

Only batches that document ≥99% purity and exact identity earn our label. Each vial is marked with a batch number that researchers can enter on our website to instantly access the full test results for that lot.

That same commitment to verifiable quality drives how we scale. Whether developing new 5 mg and 10 mg variants or expanding production for multi-center research, we treat every order as an extension of our promise: USA-verified, Gilbert-crafted, absolutely pure. By reinvesting in advanced analytical equipment and upholding a rigorous chain-of-custody system, we ensure researchers receive peptides they can trust—today, tomorrow, and for every breakthrough yet to come.
