GHK-Cu vs BPC-157
GHK-Cu is a copper-binding tripeptide for skin, hair, and dermal remodeling. BPC-157 is a soft-tissue and GI healing peptide.
Attribute
GHK-Cu
BPC-157
Mechanism
Copper-binding tripeptide; stimulates collagen, elastin, and dermal remodeling.
Angiogenic pentadecapeptide; VEGFR-2 signaling and fibroblast migration for soft-tissue repair.
Standard dosing
1–2 mg SC 2–3x weekly, or topical 0.05–0.2% for aesthetic use.
500 mcg SC twice daily loading, then once daily 4–6 weeks.
Indications
- Skin remodeling
- Hair restoration adjunct
- Wound healing
- Tendonitis / tendinopathy
- Ligament sprains
- GI mucosal inflammation
Strengths
- Dual injectable + topical utility
- Aesthetic + regenerative overlap
- Excellent GI + soft-tissue coverage
- Local injection near injury site possible
Cautions
- Copper accumulation with chronic high-dose use
- Avoid in Wilson's disease
- Compounded 503A only
- Pause 48h around surgery
- Avoid in active malignancy
FAQs
- Can they be stacked?
- Yes. GHK-Cu topically for skin/hair alongside BPC-157 SC for underlying soft-tissue is a common med-spa stack.
- Is GHK-Cu injectable or topical?
- Both. Injectable for systemic regenerative use, topical for aesthetic dermal outcomes.
