Interestingly, Ethanol treatment significantly reduced the viability of HepG2 cells, while GSH dose-dependently showed a positive influence on cell viability
Still, researchers caution that findings are largely preliminary and drawn from small cohorts rather than large, sex-stratified clinical trials
Nobody has published human pharmacokinetics showing what happens to the copper after a subcutaneous GHK-Cu injection: how much dissociates locally, how much reaches the liver, whether repeated administration accumulates, what happens to ceruloplasmin and serum copper over weeks
However, this is an area where caution is especially important
A prescription is required to ensure you receive pharmaceutical-grade peptides that meet the highest quality standards
On the topical side, the most well-known study used a nano-lipid carrier to help GHK-Cu sink deeper into the skin
