In the literature it is also known as glycyl-L-histidyl-L-lysine-Cu2+, and in dermatology and cosmetics as Copper Tripeptide-1.<\/p>\n<h2>GHK-Cu in research \u2014 mechanism &amp; evidence<\/h2>\n<p>Research attributes to GHK-Cu possible involvement in collagen synthesis, in the remodeling of extracellular matrix, in inflammatory regulation and in healing processes. Some of the evidence comes from skin and cellular research, but the scope of controlled clinical trials is limited.<\/p>\n<h3>Sources &amp; further information<\/h3>\n<p>For a full list of sources and studies, see the \"More info\" tab on this page, or browse<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GHK-Cu\" target=\"_blank\" rel=\"noopener\">GHK-Cu studies on PubMed<\/a>.<\/p>\n<h2>Reconstitution and storage of GHK-Cu<\/h2>\n<p>GHK-Cu usually comes as a freeze-dried powder.
