autoregulatory control of mitochondrial glutathione homeostasis Glutathione: Regulation and Functions Mitochondrial glutathione transporter SLC25A40 regulates

While glutathione provides many benefits, it is not a magic pill for either weight loss or perfect skin

A separate study demonstrated that copper-free GHK increases stemness and proliferative potential of basal epidermal cells, with increased integrin expression suggesting enhanced stem cell activity (Badenhorst et al., 2012)

In one mouse study, researchers found that the peptide reduced the pain felt by the animals in their paws when placed on a mildly hot plate. The authors explained that this could be because GHK is similar in structure to cimetidine, a histamine H2 receptor antagonist sometimes given to reduce pain in certain digestive conditions.3 10 In rodents, doses as low as 0.5mg/kg were found to be effective in delivering these anti-pain effects.25 In a 70kg human, an equivalent dose would be around 5.6mg, though thats likely higher than necessary: pharmaceutical-grade GHK-Cu normally ranges from 0.5 mg to 2.5mg per injection

The micro-channels created by the needles also temporarily increase permeability, improving topical GHK-Cu uptake if applied in the post-procedure window
