Researchers interested in skin-visible anti-aging effects tend to study GHK-Cu
Pre-treatment of HGF with trisulfides and nitration Recombinant mouse HGF (carrier protein-free) was pre-treated with glutathione trisulfide (GSSSG) and lipoic acid trisulfide (LASSS) at mole ratios (HGF : trisulfide) of 1:0 (with solvent alone), 1:400, 1:1000, and 1:4000 at pH 7.4, 25C just prior to the peroxynitrite protocol (optimized at a molar ratio 1:2000 relative to HGF, pH 7.4, 37, for 30 min), which was previously demonstrated to induce maximal nitration of Y198 and Y250 located in the -chain under physiological conditions as described previously 32
Now, researchers from the University of Washington report in Aging Pathobiology and Therapeutics that the GHK peptide prevents sleep-deprived learning impairment in aging mice
Glutathione, a natural antioxidant found in most cells, plays a key role in maintaining cellular health
The appropriate amount depends on the form, reason for use, concurrent precursors, medical history and clinician guidance
Thats where professional treatments come in
