GHK-Cu
Skin, hair, healing
The copper peptide that rebuilds skin, hair, and the extracellular matrix.
Also sold as
Research chemical vendors can't legally label products with the real name, so GHK-Cu often appears under coded SKUs. If you're shopping and see any of these, it's the same compound:
- GHK
- Copper Peptide
- GHK-Copper
Codes shown are for identification only.
Your draw
What it actually is
A naturally occurring tripeptide (Gly His Lys) bound to copper. Plasma levels drop sharply with age. Restoring it activates fibroblasts, increases collagen and elastin synthesis, and accelerates wound healing.
Why people use it
- Reversing skin thinning, fine lines, and laxity
- Hair regrowth in androgenic and stress related thinning
- Faster recovery from cosmetic procedures (microneedling, laser)
- Subcutaneous injection systemically; topical for targeted skin work

Typical timeline
General pattern for the Healing category. Individual response varies.
- Week 1Subtle. You may notice slightly less pain or better range of motion. Don't push injuries yet.
- Weeks 2–4Clear improvement in pain and tissue tolerance. Begin controlled loading of the injured area.
- Weeks 4–8Peak repair phase. Function returns. Keep dose consistent — skipping days slows the curve.
- Post-cycleGains generally stick if you also fixed the underlying mechanics (form, load management, mobility).

The reconstitution math
- 1Reconstitute the 50 mg vial with 3 mL of bacteriostatic water. Tilt — don't shake.
- 2Concentration becomes 16,666.667 mcg/mL (16.667 mg/mL).
- 3For a 2 mg dose, draw 0.120 mL — that's 12 units on a 1 mL insulin syringe.
- 4One vial gives you approximately 25 doses.
Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
