biosynthesis of glutathione Synthase - an overview Pathway showing biosynthesis and metabolism

Rat full-thickness wounds (6mm diameter, 13-day study) treated with GHK showed 64.5% reduction in wound size compared to 45.6% for vehicle-treated and 28.2% for control group, accompanied by significantly lower TNF- and elastin-degrading MMPs

UV light catalyzes copper ion oxidation, which breaks the peptide-copper coordination bond and renders the compound biologically inactive

Glutathione depletion can lead to increased oxidative stress, DNA damage, and impaired detoxification

They partner with independent labs to conduct quality testing on all of their products

The tissue has had enough time to undergo cellular turnover and strengthening
