Stimulation of hair follicles In studies on hair follicles GHK-Cu: Prolongs the anagen phase (the active growth phase) Stimulates dermal papilla cells (the control center of the follicle) Increases blood supply to follicles (via angiogenesis) This is the research basis for AHK-Cu (an analogous copper tripeptide optimized for hair) and for cosmetic formulations against hair loss

Temporary shedding: Similar to other growth agents, some users report brief periods of increased shedding as follicles cycle into new growth phases

Compounds that influence growth-factor signaling warrant careful oversight, and unsupervised use, especially of products from unregulated sources, carries real risk
