AHKCU
Cosmetic Peptide
AHK-Cu peptide is a copper-binding tripeptide — the copper(II) complex of L-alanyl-L-histidyl-L-lysine, also known as Copper Tripeptide-3 — structurally related to GHK-Cu. AHKCU is supplied as a research material with third-party HPLC and mass spectrometry testing, for laboratory research use only.

Frequently Asked Questions

AHK-Cu is the copper(II) complex of the tripeptide L-alanyl-L-histidyl-L-lysine (Ala-His-Lys). It's commonly referred to as Copper Tripeptide-3 in cosmetic-ingredient nomenclature and research literature.
AHK-Cu peptide is used in laboratory research examining copper-binding tripeptide chemistry and its effects on dermal fibroblast and dermal papilla cell activity in cell-culture and ex vivo hair-follicle models. It is not used for any human or veterinary purpose.
AHKCU 50 mg is a 50 mg research quantity of AHK-Cu peptide, supplied by Prime Time BioLabs as a sterile lyophilized powder for laboratory use.
Yes. AHK-Cu is a copper-binding tripeptide — three amino acids (alanine, histidine, lysine) joined in sequence and complexed with a copper ion.
AHK-Cu is a structural analog of GHK-Cu, with alanine substituted for glycine at the N-terminus. The two compounds are chemically related but are studied as distinct compounds — research findings on one should not be assumed to apply to the other.
AHKCU 50 mg ships as a sterile lyophilized powder in a light-protected vial containing a nominal 50 mg of AHK-Cu, labeled with its lot number.
Every batch is independently verified using HPLC and mass spectrometry before release. HPLC establishes purity; mass spectrometry confirms molecular identity.
HPLC (high-performance liquid chromatography) measures the target compound's proportion relative to any detected impurities, expressed as a purity percentage. It does not by itself confirm molecular identity.
Mass spectrometry confirms molecular identity by comparing a sample's measured mass against the expected mass for AHK-Cu. It does not report a purity percentage.
Yes. Every batch is third-party tested, and a COA matching the lot number on your vial — including batch number, purity result, and analysis date — is available for download from your account after purchase.
AHK-Cu has been studied in ex vivo human hair-follicle organ culture and in cultured dermal papilla cells, where it has been shown to stimulate follicle elongation and cell proliferation at low concentrations. This evidence base is narrower than GHK-Cu's and is concentrated in cell-based and ex vivo models; robust peer-reviewed human clinical trials specific to AHK-Cu are limited.
No. AHKCU 50 mg is supplied strictly for in-vitro laboratory research use. It is not approved for human or veterinary use, has not been reviewed by the FDA, and must not be used as a food, drug, or cosmetic.
