FAQ
Before you send an RFQ.
How does AHK-Cu differ from GHK-Cu?
Both are copper-complexed tripeptides with different sequences: AHK-Cu is Ala-His-Lys (Copper Tripeptide-3), GHK-Cu is Gly-His-Lys (Copper Tripeptide-1). They have separate CAS numbers and are separate SKUs.
What is on the COA?
HPLC purity against our NLT 98.0% release specification, MS molecular-weight identity, the lot number and test dates. Published lots are in the public COA library, and independent testing of your sample is welcome.
Can you supply it under our own label?
Yes, from 100 kits (1,000 vials): your label, carton and insert on our vials. Neutral label is the default. See OEM details.
