What is AHK-Cu??
AHK-Cu (Alanine-Histidine-Lysine Copper Tripeptide-3, CAS 49557-75-7) is a synthetic copper-binding tripeptide specifically engineered to target hair follicle signalling. Unlike the naturally occurring GHK-Cu (Copper Tripeptide-1), AHK-Cu is lab-designed with superior copper-binding stability and a more follicle-directed mechanism — stimulating dermal papilla cells, promoting VEGF-mediated angiogenesis around the follicle, and extending the anagen (growth) phase. It also retains collagen and elastin synthesis activity relevant to skin remodelling research.

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
