Table 5 Genes relevant to DNA repair affected by GHK 4.7 GHK vs GHK-Cu 4.7 GHK vs GHK-Cu There are many studies that obtain significant results with copper-free GHK, but the copper chelator bathocuproine abolishes the GHK effects
For patients pursuing systemic regenerative protocols, wound healing support, or broader anti-aging applications where body-wide distribution is the goal, injectable has a legitimate clinical role under physician supervision through an accredited compounding pharmacy
GHK-Cu works through a different mechanism, supporting the follicle environment rather than blocking DHT
Capsules, injections, nasal sprays, creams, and suppositories have all been proposed
Intramuscular injections generally cost $50-150 per shot, administered 1-2 times weekly initially, then monthly for maintenance
