These dont directly supply the precursor amino acids for glutathione, but they signal your body to ramp up its own antioxidant production, thereby indirectly boosting glutathione levels 23
A 2022 RCT (n=50 androgenetic alopecia patients) used 0.5% GHK-Cu serum, increasing hair count by 22% at 16 weeks versus 8% minoxidil (p=0.01) (Park et al., 2022)
Emu oil can be used on top of this cream if you wish as a penetration enhancer and/or for extra hydration
Post-treatment side effects
It was demonstrated that GSH level affects the selective elimination of mitochondria (mitophagy) in S
On the other hand, the gene expression of mitochondrial biogenesis markers ( PGC1 , AMPK , SIRT1 , NRF2 , and MFN2 ) and mitochondrial activity marker ( COXIV ) in liver-specific GHRKO (LiGHRKO) and wild-type mice are significantly different between the males and females, suggesting that sexual dimorphism may also play an essential role in regulating the mitochondrial biogenesis (Zawada et al., 2015)
