Beyond that landmark study, the evidence base includes research showing GHK-Cu enlarges hair follicle size, extends the anagen (active growth) phase, stimulates dermal papilla cells (the cells that control follicle activity), promotes angiogenesis (blood vessel growth) to the scalp, and reduces the DHT-related inflammation that causes follicle miniaturization in androgenetic alopecia

This study showed that doses of 500-1000 mg were sufficient to reduce markers of oxidative stress
half-life: ~30 min2 hours Plasma levels decline ~60% with age (~200 ng/mL at age 20 ~80 ng/mL at age 60) Influences expression of ~31% of studied human genes linked to repair and regeneration Stimulates collagen type I and III synthesis by up to 70% in studied models Activates fibroblasts
