AHK 200mg (Tripeptide-3) is the copper-free Ala-His-Lys peptide powder from Peptide Sciences, used in cosmetic formulation research.
AHK Research Overview
Copper-free AHK allows formulators to test the peptide alone or add copper in controlled amounts. It is used as a baseline when studying the effect of copper complexation in AHK-Cu.

Research Considerations
Using copper-free AHK alongside AHK-Cu gives formulators a clean way to determine whether a given effect requires copper, which also guides decisions on product colour and stability.
Quality Control, COA and Shipping
Consistency between lots is checked by HPLC and mass spectrometry, so researchers can compare results across experiments with confidence. Each order ships with a lot-specific Certificate of Analysis and cold-chain packaging.
