The Structure Protocol

What it addresses

Collagen synthesis declines 1–1.5% annually after the mid-20s. The Structure Protocol delivers GHK-Cu — a naturally occurring copper tripeptide that signals fibroblasts to produce collagen, elastin, and glycosaminoglycans — directly to the skin at full potency through freeze-dried point-of-use activation.

Research across six decades documents GHK-Cu's role in tissue remodeling, antioxidant defense, and angiogenesis. Plasma GHK-Cu levels decline approximately 50% between early adulthood and the 60s — this protocol restores that signaling environment.
