While research confirms the antioxidant and anti-inflammatory benefits of the GHK-Cu copper peptide, that doesnt mean that its a wonder drug, and you are likely better directed to other care solutions for hair growth (although it may help to calm inflammation on the scalp) or weight loss (thats where peptide-based drugs like Ozempic are proven to help)
