Twice daily, topical, clinician-prescribed
Older subjects had cysteine and glycine added to their diets to increase glutathione levels, which spiked within two weeks, improving insulin resistance and fat burning
Speed of results: GHK-Cu shows measurable collagen changes within 4 to 8 weeks
Using Connectivity Map data from the Broad Institute, researchers found that GHK modulates 4,000+ genes
Extremely small or large individuals may adjust slightly, but most researchers use standard fixed doses successfully
Additionally, GSEA analysis of iSPN + mut at 3 months revealed a significant reduction in the expression of genes associated with the first stage of the cellular respiration process glycolysis and the tricarboxylic acid cycle, followed by a further decrease at 8 months (Supplementary Table 1b,c,e,f)
