Maquart 1988 J Clin Invest showed that GHK-Cu at nanomolar concentration stimulates type I collagen synthesis by fibroblasts by 60-200 %, of glycosaminoglycans (hyaluronic acid, heparan sulphate) and proteoglycans

The assay for -glutamylcysteine synthetase activity is based on the formation of GSH from cysteine, glutamate and glycine in the presence of the excess of glutathione synthetase

For example, in 2015, a randomized clinical trial of elderly men with sarcopenia found that 15g of daily collagen peptide supplementation, in combination with resistance training, led to improvements in multiple parameters: muscle strength, fat mass, and fat-free mass.40 For another example, a 2023 study of subjects with ultrasound-confirmed musculoskeletal inflammation concluded that locally injected collagen peptides could effectively and safely treat collateral ligament pain, indicating positive implications for physical recovery.41 It isnt clear how collagen compares to other peptides in facilitating these outcomes, as head-to-head studies arent available
