There are websites online such as Peptides Direct and Auspep that sell it
First identified in human plasma in the 1970s, this small tripeptide glycyl-L-histidyl-L-lysine, bound to a copper ion has become one of the most extensively referenced compounds in dermal and wound-healing research literature, largely because its copper-binding structure gives it a distinct mechanism from most other peptide sciences on the market
Reported activities include fibroblast stimulation, controlled intracellular copper delivery, modulation of collagen and glycosaminoglycan synthesis, and broad changes in gene expression across stress-response and tissue-repair networks
Respiratory Tissue Repair and Protection COPD fibroblast restoration occurs at 10 nanomolar concentration, restoring lung fibroblasts ability to contract and restructure collagen while elevating integrin beta 1 expression
It works best for localized disease or as a complement to systemic treatment for targeted management of persistent plaques
