Injectable GHK-Cu reaches follicle-depth tissue at 10 to 20 times the concentration of topical serums, making it more effective for moderate-to-advanced loss
This accumulation contributes to liver disorders and alcohol associated toxicity symptoms, including hangovers
Another review of studies involving BPC-157, as well as TB-500, GHK-Cu, and several other peptides, similarly found a lack of evidence to support clinical use of the substances
Alternatives to Injecting GHK Topical copper peptide treatments such as serums, creams & even copper nasal sprays are a financially accessible and routine-friendly alternative to GHK-Cu injections
