GHK-Cu reversed years of sun damage. Age spots fading, skin texture smoother. The copper peptide mechanism stimulates collagen and elastin. Injected version works better than topical for me. No side effects.
9 days since first dose of GHK and finally had the sting. Skin looks younger, hair seems thicker. Wound healing accelerated noticeably. Not for tanning - that's melanotan. But for anti-aging skin effects, GHK-Cu is excellent.
GHK-Cu completely transformed my skin. Wrinkles reduced, elasticity improved, fine lines faded. Collagen production is visibly increased. Also noticed faster wound healing. The stinging sensation at first is normal - it means it's working.
