AHK (Tripeptide-3) 200mg Topical Overview
AHK (Tripeptide-3) 200mg Topical from Peptide Science is the synthetic alanyl-L-histidyl-L-lysine tripeptide, the alanine-substituted analog of the naturally occurring GHK plasma tripeptide. Supplied as a topical research formulation for in-vitro hair-follicle and dermal-papilla cell-culture work without the palmitoyl conjugation of Pal-AHK.
Compound Class and Mechanism
AHK retains the histidine and lysine residues that give the parent GHK family its copper-coordination affinity, with the N-terminal alanine substitution providing distinct cell-culture activity from the parent GHK and GHK-Cu forms. Preclinical research has characterised the tripeptide for hair-follicle cell-culture effects and dermal-papilla cell signalling. Browse the broader cosmetic peptide range.
