Copper-binding tripeptide for skin, hair, and tissue remodeling.
01 · Overview
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine bonded to copper) first isolated from human plasma in 1973. Plasma levels drop from around 200 ng/ml at age 20 to under 80 ng/ml by age 60 — a decline that tracks with visible aging.
What makes it useful is that it does two things at once: delivers copper to fibroblasts (which need it to build collagen and elastin) and directly signals genes involved in tissue repair and antioxidant defense. Skinnier research shows it modulates over 4,000 human genes toward a 'younger' expression profile.
02 · Fit
Anyone focused on skin quality, early hair thinning, or scar remodeling — a common gateway peptide for aesthetic goals.
03 · Mechanism
GHK-Cu modulates collagen and elastin synthesis, upregulates antioxidant defenses, and improves wound remodeling via copper delivery to fibroblasts.

05 · Protocols
Reference protocols paraphrased from published research and common clinical practice. Individual response varies. Work with a qualified provider before running anything below.
Skin quality (subcutaneous)
Protocol
1–2mg subcutaneous daily, injected in the abdomen or thigh
Duration
8–12 weeks on, 4 weeks off
Notes
Rotate injection sites. Systemic dosing helps overall skin, not just the injection area.
Hair support (subcutaneous or scalp)
Protocol
2mg subcutaneous daily, OR compounded scalp serum at 0.05–0.2%
Duration
12+ weeks — hair cycles are slow
Notes
Often combined with topical minoxidil. Give it a full follicle cycle before judging results.
Post-procedure / scar remodeling (topical)
Protocol
Compounded 0.1–0.2% cream applied twice daily
Duration
6–12 weeks after the procedure
Notes
Wait 24–48 hours post-procedure before starting to avoid irritation.
Baseline reconstitution
Reconstitute 100mg with 5ml BAC water for 20mg/ml.
06 · Combinations
Pairs naturally with glutathione for antioxidant support and skin tone, and with BPC-157 when recovering from a procedure. TB-500 is a common add for anyone chasing broader connective-tissue repair.
07 · Safety
08 · Trivia
09 · FAQ
Subcutaneous gives systemic effects (whole-body skin, hair, healing). Topical is stronger locally for a specific area (a scar, a wrinkle, the scalp). Many users do both.
No. You may see a faint blue dot at the injection site for a few minutes — that's the copper visible through thin skin. It fades quickly.
Skin texture usually shifts around week 4–6. Deeper firmness and elasticity keep improving through week 12.
