While GHK-Cu is not a growth hormone secretagogue, it exerts potent localised effects relevant to both hair and skin: Promotion of angiogenesis , increasing capillary density around follicles Stimulation of stem cell migration and differentiation Inhibition of transforming growth factor beta (TGF-) , a cytokine associated with follicular miniaturisation Enhancement of collagen and elastin synthesis , improving scalp elasticity and barrier function Topical GHK-Cu formulations, available through Dn Research in research-grade purity, can be incorporated into routine scalp applications to directly support the hair follicle microenvironment

Reported outcomes include: Falling asleep faster Fewer nighttime wake-ups More vivid dreams (a sign of longer REM cycles) Improved mood, cognitive performance, and recovery MK-677 significantly enhanced REM and slow-wave sleep in both younger and elderly subjects, suggesting therapeutic potential for sleep disorders and age-related GH decline.
