FAQ
AHK-Cu — frequently asked by B2B buyers.
What form and vial sizes does Pepti supply AHK-Cu in?
AHK-Cu ships as a lyophilized (freeze-dried) blue-tinted powder in sealed 20 mg and 50 mg vials. Bulk powder and custom fill weights are available on request. Minimum order is 50 vials.
What documentation comes with each lot?
Every lot ships with a Certificate of Analysis reporting HPLC purity, mass-spectrometry (MS) identity confirmation, and appearance. TDS/SDS and additional third-party COA verification are available for private-label and import files on request.
What purity specification does Pepti hold for AHK-Cu?
Standard specification is not less than 98% by HPLC. Exact per-lot purity, water content, and copper content are stated on the COA; tighter specifications can be quoted for specific formulation or regulatory requirements.
How does AHK-Cu differ from GHK-Cu?
Both are copper-complexed tripeptides, but the sequences differ: AHK-Cu is Ala-His-Lys (Copper Tripeptide-3) while GHK-Cu is Gly-His-Lys (Copper Tripeptide-1). They are distinct compounds with separate CAS numbers and are stocked as separate SKUs.
Can Pepti support private-label and OEM orders?
Yes. We provide OEM and private-label services including custom vial labeling, fill weights, cosmetic-grade documentation, and bulk raw-material supply. Site framing is research-use / B2B; regulatory classification and finished-product compliance in the buyer's market remain the buyer's responsibility.
