These mechanisms are investigational
The free GHK tripeptide was first isolated from human plasma in 1973 by Loren Pickart, and the copper-bound form has been studied since the 1980s as a regenerative-research reference compound.nnActive research areas include extracellular matrix gene expression, collagen and decorin regulation, matrix-metalloproteinase modulation, antioxidant pathway activity, and copper-mediated cell signalling

Its a smart alternative to synthetic HGH for anti-aging support
On the other hand, there is no evidence that the Fragment 176-191 presents some of the hGH-associated risks like edema, hypertension, acromegaly, diabetes, or glucose intolerance
