Description

GHK-Cu is a naturally occurring tripeptide that binds to copper to form a small, stable complex the skin recognizes. Levels of it drop with age, and most of the modern research on it asks what happens when those levels are restored.

Published work points to its role in collagen and elastin synthesis, hair follicle signaling, antioxidant activity, and wound healing, which is why it shows up across both dermatology and longevity literature.

One of the most-studied peptides in the category, with a strong safety profile across decades of clinical and lab use.
