Preclinical Research on GHK-Cu and Cellular Regeneration Preclinical research on GHK-Cu explores fibroblasts, collagen, glycosaminoglycans, angiogenesis, inflammation, matrix metalloproteinases, tissue inhibitors, and wound models [4], [5], [10], [12]
Many injuries heal but leave behind tissue that functions poorly
The two therapies do not share metabolic pathways or compete for the same receptors, so combining them does not create pharmacological conflicts
It also notes GHK-Cus ability to influence gene expression and promote cellular repair processes that decline with age
The formulation combines reduced L-glutathione with cyclodextrin, ascorbic acid, dexpanthenol and selected extracts such as Leuconostoc/radish root extract ferment filtrate, Lonicera japonica, Lonicera caprifolium and Populus tremuloides bark extract
it is precisely this property that critics flag as an unquantified concern, for example in the context of occult neoplasia or proliferative diseases
