GHK-Cu vs NAD+

Two compounds, mechanism by mechanism. Where they overlap, where they don't, and which vendors stock each.

§ 01

Mechanism

ghk-cu

GHK-Cu

Copper peptideGlycyl-L-histidyl-L-lysine-Cu

Naturally occurring copper-binding tripeptide. Well-documented in dermatology literature for collagen synthesis and wound healing.

vs
nad-plus

NAD+

Nicotinamide Adenine DinucleotideNAD

Coenzyme central to redox reactions and energy metabolism in every cell. Levels decline with age, which has driven a research interest in NAD+ supplementation as a longevity intervention.
