GHK-Cu acetate is a complex of the tripeptide Gly-His-Lys and a copper(II) ion that has wound healing and anti-inflammatory activities. It increases proliferation and the levels of collagen and secreted pro-matrix metalloproteinase-2 (MMP-2) in isolated human fibroblasts. GHK-Cu increases levels of collagen and glycosaminoglycans (GAGs) and the expression of decorin in the wound tissue of rats. It decreases LPS-induced increases in the levels of reactive oxygen species (ROS), IL-6, and TNF-α in RAW 264.7 cells when used at a concentration of 10 μM.3 GHK-Cu (10 μg/g) prevents LPS-induced decreases in lung superoxide dismutase (SOD) activity and glutathione (GSH) levels and reduces LPS-induced increases in the number of cells and the level of total protein in bronchoalveolar lavage fluid (BALF) in a mouse model of acute lung injury.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
