What does GHK-Cu stand for?

GHK is the amino-acid chain glycyl-L-histidyl-L-lysine, a three-part peptide that holds copper. Cu stands for the copper in that complex. This site's GHK-Cu profile lists the chemical name Copper Tripeptide-1, another name of copper peptide, and molecular weights of 340.38 daltons for the peptide alone and 402.92 daltons with the copper. A 1988 paper on skin cells cited on that page spells the complex as glycyl-L-histidyl-L-lysine-Cu2+. The letters are short for the chain, not a brand. On their own, they say nothing about whether a cream, a capsule, or a shot has been tested.

Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.

Part of names, absences, and legal limits. Brand versus molecule, side effects this site's citations did not measure, how long the trials actually ran, what national legal-status fields can say, and why two-compound answers do not scale to a larger stack.
