Our Guarantees
98% Purity Guarantee
NorthPeptide backs every order with a minimum 98% purity guarantee. If independent testing shows purity below 98%, you get a full refund.
Laboratory Tested
Products are sent to independent laboratories and every figure they report is published on our test results page before you order — laboratory, date, and who commissioned the test. These are panel tests rather than per-lot runs, so they do not trace to the individual vial you receive, and the page says so plainly.
Ships from the US
Orders ship from within the United States with tracking and are processed within 1–2 business days. If there's a problem with your order, contact us and we'll make it right.
