In rabbit studies, GHK-Cu treatment was associated with wound contraction and granulation tissue formation
It is produced during normal glutathione-dependent peroxide reduction and can be converted back to GSH by glutathione reductase
Therefore, NO can mediate ROS-induced lipid peroxidation (LPO)
To round out the formula, Vitamins C and E, milk thistle extract and L-cysteine hydrochloride are added to support glutathione activity and synthesis, helping your body maintain its antioxidant defenses
FDA staff's own briefing document, posted publicly ahead of the meeting as part of the docket, proposes that TB-500 (free base) and TB-500 acetate not be added to the list, citing incomplete physicochemical characterization, a lack of evidence of effectiveness for wound healing (including an in-vitro fibroblast study in which TB-500 reportedly did not induce wound healing), and insufficient nonclinical and clinical safety data
