They want to lose fat, protect muscle, maintain energy, support hormones, reduce metabolic risk, and avoid the frail or depleted look that can happen with rapid weight loss
Low glutathione levels are linked to chronic fatigue and low energy production
in fibroblast culture models it stimulates collagen, elastin, and glycosaminoglycan synthesis at picomolar to nanomolar concentrations (10 to 10 M), and modulates metalloproteinase (MMP-1, MMP-2, MMP-9) activity and their inhibitors (TIMP-1, TIMP-2), functioning as a general regulator of extracellular matrix remodeling ( Mechanistic research establishes that GHK activates TGF- and integrin 1 pathways during tissue repair, attracts immune and endothelial cells to wound sites, and restores gene expression patterns toward a healthier fibroblast phenotype in models of aging and radiation damage ( A 2018 review in IJMS characterizes its role in collagen production, nerve outgrowth stimulation, and dermal stem cell marker expression ( For Research Use Only
