Reference values from published literature. The lot certificate is the authority for a specific vial.
Store unopened vials of freeze-dried powder at −20 °C, protected from light and moisture. Short periods at room temperature in transit do not affect lyophilised material. Let a vial reach room temperature before opening so condensation does not form inside.
We ship within the United States only, by FedEx 2Day, cold-packed and tracked, with delivery expected by 5 p.m. on the scheduled delivery date. Orders placed before 10 a.m. PT (1 p.m. ET) on business days ship the same day. No weekend dispatch. Shipping is free on peptide orders over $250.
Online payment for US orders is not yet available. We only list payment methods that are live, and card payment will be added once approved. Orders ship only after payment is received. All sales are final. Replacement applies only to damage, loss in transit or a wrong item.
GHK-Cu: COA pending. The certificate is published on Lab Results as soon as the lot is released.
