Our objective is to present the pharmacological mechanisms, safety profiles, and regulatory status of prominent approved and unapproved peptides marketed direct to patients, including AOD-9604 (anti-obesity drug 9604), BPC-157 (body protection compound 157), CJC-1295, FS-344 (follistatin-344), GHK-Cu (glycyl-l-histidyl-l-lysine copper), ipamorelin, MOTS-C (mitochondrial ORF of the 12S rRNA type-c), sermorelin, SS-31 (elamipretide), tesamorelin (Egrifta), T4 (thymosin beta-4), and TB-500 (thymosin beta-4 fragment)
The tripeptide has high affinity for copper, and most of GHK's documented biological activity in the published literature is mediated by the copper complex particularly its effects on antioxidant enzyme activity, ECM remodeling, and gene expression
