Originally identified by Loren Pickart in human plasma, GHK-Cu has been the subject of extensive cellular biology and biochemical research literature for over five decades, with research contexts examining tissue biology, cellular signaling pathways, copper-binding peptide chemistry, and extracellular matrix research
Side effects: Very rarely skin symptoms and hypersensitivity reactions
The testes contain an abundance of GSH-dependent dehydroascorbate reductase, which keeps vitamin C itself in a reduced condition [171, 172]
