Growth hormone, for its part, increases cellular replication, encourages collagen synthesis in your skeletal muscles, and stimulates the production of a separate hormone called insulin-like growth factor-1 (IGF-1), which helps regulate the process by which your body creates fat.1 2 3 Given these qualities, a higher concentration of circulating growth hormone can lead to improved exercise training, increased muscle strength, and a decreased propensity for fat accumulation.4 Despite belonging to the same category and effecting a common outcome, CJC-1295 and ipamorelin have distinct mechanisms of action: CJC-1295s mechanism of action CJC-1295 mimics a chemical from the hypothalamus called growth hormone-releasing hormone (GHRH), which tells the pituitary gland to release growth hormone.5 Ipamorelins mechanism of action Ipamorelin is an analog of ghrelin, a hormone originating from the cells in your stomach.6 As such, it binds to the brains ghrelin receptor and, like GHRH, stimulates growth hormone secretion from the pituitary
