GHK‑Cu (Copper Tripeptide‑1) by Hilma Biocare — regenerative peptide
GHK‑Cu is a copper‑bound tripeptide (gly‑his‑lys) that acts as a signal molecule in tissue repair, wound healing and skin rejuvenation. Its small size enables rapid diffusion through the intercellular space, where it regulates copper‑ion availability for essential enzymatic processes.
Key properties
- Accelerated wound healing: Improves closure of chronic or poorly‑circulated wounds and lowers scar formation.
- Antioxidant & anti‑inflammatory: Boosts antioxidant enzymes, reduces inflammatory cytokines and protects cells from oxidative stress.
- Gene‑regulatory activity: Modulates >4 000 genes linked to cellular rejuvenation and repair.
- Collagen & moisture synthesis: Stimulates fibroblasts, increases collagen, elastin and hygroscopic molecules, enhancing skin texture and hair growth.
Dosage & administration
- Route: Sub‑cutaneous injection into fatty tissue (commonly abdominal).
- Injection protocol: Alternate injection sites with each dose.
- 30‑day cycle (two 15‑day phases):
- Days 1‑15 – 1 mg /day
- Days 16‑30 – 2 mg /day
The regimen relies on cumulative tissue exposure rather than peak levels; an optional repeat cycle can follow a 30‑day break.
- Missed dose: Continue the schedule as normal; do not double the next dose.
Contra‑indications
- Active malignancies.
- History of hormone‑dependent cancers (consult oncologist).
- Pregnancy or lactation (insufficient safety data).
Drug interactions
- Combines well with most regenerative peptides (e.g., NAD+, N‑Acetyl Semax) when administered from separate vials.
- Do **not** mix different peptides in the same syringe or vial.
- Always verify compatibility with a physician.
Side effects
- Generally well‑tolerated.
- Most common: mild transient redness at the injection site.
Compatibility with other products
GHK‑Cu is frequently stacked with NAD+, N‑Acetyl Semax, peptide‑based regenerative protocols and anabolic regimens under professional supervision, providing synergistic tissue‑repair benefits.
Conclusion
GHK‑Cu by Hilma Biocare offers a research‑grade copper peptide that supports wound healing, antioxidant defense, collagen synthesis and overall skin‑health, with a simple sub‑cutaneous dosing schedule and minimal side effects when used correctly.
