This is consistent with GHK-Cus known role in upregulating collagen synthesis in dermal fibroblasts, a mechanism confirmed in a comprehensive review in Biomolecules documenting GHK-Cus influence across more than 4,000 human genes involved in tissue remodeling and repair
The FDA indicated it was not aware of any basis for compounding using salt forms that would meet FD&C requirements, reporting that products containing these salts, such as semaglutide sodium and semaglutide acetate, have not been shown to be safe and effective. 16 The risk of overdose is also higher with compounded versions
A second strategy is to induce an overexpression of endogenous and exogenous DNA repair genes (such as overexpression of O6-alkylguanine DNA alkyltransferase and yeast AP endonuclease) to enhance the efficiency of endogenous DNA repair and to reduce mutagenesis and associated carcinogenesis (177, 178)
This expansion is being implemented through demonstration authorities, not a permanent change in law, but it represents a significant shift
