BPC-157 vs GHK-Cu
An educational, source-based comparison of BPC-157 and GHK-Cu — how each peptide works, what it's researched for, and what to know before going deeper.
A pentadecapeptide (15 amino acids) derived from a protective protein found in human gastric juice. Research suggests it modulates the nitric oxide system, upregulates growth hormone receptors in injured tissue, and promotes angiogenesis (formation of new blood vessels) — mechanisms associated with accelerated tendon, ligament, muscle, and intestinal mucosa repair in preclinical models.
- Tendon-to-bone healing
- Ligament and muscle recovery
- Gastric ulcer protection
- Inflammatory bowel models
- Neuroprotection (rodent)
- • Human clinical trials are limited — most research is preclinical.
- • Not FDA-approved for human therapeutic use.
- • Quality, purity, and dosing of compounded peptides vary widely.
A naturally occurring tripeptide (Glycyl-L-Histidyl-L-Lysine) that forms a complex with copper(II) ions. Research indicates it modulates ~4,000 human genes, downregulating those associated with inflammation and tissue breakdown while upregulating genes tied to collagen synthesis, antioxidant defense, and stem cell activation.
- Collagen and elastin synthesis
- Wound healing
- Hair follicle stimulation
- Skin barrier and antioxidant capacity
- Anti-glycation in dermal fibroblasts
- • Topical formulations have decades of cosmetic safety data; injectable use is less studied.
- • Copper sensitivity is rare but possible.
- • Compounded injectable GHK-Cu is not FDA-approved.
