GHK-Cu
Supports collagen production, skin repair, and hair growth
Rebuilds skin, hair, and connective tissue.
A copper-carrier tripeptide that signals fibroblasts to lay down collagen, elastin, and glycosaminoglycans — the core scaffolding of youthful skin.
- Best-documented effect: skin firmness, wound healing, and hair density.
- Activates stem cells in hair follicles when applied topically.
- Reduces visible lines and thickens dermis in clinical dermatology studies.
GHK-Cu is a small copper-binding peptide that your body produces naturally — but levels decline sharply with age. It signals skin cells to make more collagen and elastin (the proteins that keep skin firm), accelerates wound healing, reduces inflammation, and may increase hair follicle size.
How long it stays, how it leaves.
Fixed dosing — not weight-adjusted. The calculator handles reconstitution math for common vial sizes so you inject the right volume every time.
Three tiers, three goals.
What people actually report.

Before you start.
- Your body already makes this naturally, so it's well-tolerated
- Cream/topical is the most common and safest way to use it
- Talk to a doctor before injecting
Combinations worth knowing.
