Overview

A naturally occurring copper complex whose levels decline with age. Studied for skin remodeling, wound healing, and hair-follicle stimulation.

Mechanism of action

Modulates ~4,000 genes — many tied to tissue remodeling, antioxidant defense, and inflammation reduction.

Typical protocol

Topical or subQ, 1–3 mg daily for skin/hair protocols.

Storage

Reconstituted: refrigerated 2–8°C, ~30 days.
