Continue ShoppingMinuteman Peptides exists for one reason: American researchers deserve a supplier that answers the call — every batch verified, every certificate published, every order shipped from US soil.
Ready at a minute’s notice
Our namesake is the citizen-soldier who kept his powder dry and his musket ready. We run our supply chain the same way. Research-grade peptides are synthesized and lyophilized to strict quality standards, held as stable freeze-dried powder, and dispatched fast so your work never waits on us.
We are an American company serving American laboratories. We manufacture and fulfill domestically, and we ship exclusively within the United States.
Verified, not promised
Every lot is independently tested by third-party US laboratories using HPLC and mass spectrometry before it is released. We guarantee 98% or better purity on every peptide we sell — and we publish the Certificate of Analysis for each batch so you can confirm identity, purity and endotoxin results for yourself.
No batch reaches a shelf until its paperwork does. If a lot does not meet our purity standard, it does not ship.
