Research context.
Public references are less standardized than GHK-Cu. Nexus should treat AHK-Cu identifiers as supplier-COA dependent and verify whether the vial is free peptide, copper complex, acetate salt, or another counter-ion form.
Verification standard.
Every Nexus Laboratory batch ships with a Certificate of Analysis documenting HPLC purity (target ≥98%), mass spectrometry identity (expected versus observed mass), and endotoxin screening — verified by third-party laboratory testing and publicly archived. Review Nexus lab verification.
AHK-CU is part of the Nexus Cosmetic & Skin catalog. Copper peptides and cosmetic signaling compounds. Each listed variant is priced from the consolidated Nexus catalog and intended for qualified research use only.
