Understanding the Science The science of GHK-Cu is grounded in three interconnected areas: copper biochemistry in mammalian tissues, the coordination chemistry of histidine-containing peptides, and the cellular and tissue-level biology in which the tripeptide and the copper it carries have been studied

Because making and purifying peptides is so complicated, it's hard to switch suppliers, which makes choosing the first source even more important
GH secretagogues like Sermorelin and Ipamorelin have been used clinically for years with good safety profiles
IGF-I, which mediates most of the effects of GH on skeletal metabolism, promotes chondrogenesis and increases bone formation by regulating the functions of the differentiated osteoblasts[357, 358]
