This stimulates the synthesis and release of endogenous growth hormone. Growth hormone subsequently acts on the liver and other peripheral tissues, increasing: Insulin-like growth factor 1 Insulin-like growth factor binding protein 3 GH-dependent metabolic signaling Lipolytic and tissue-remodeling pathways In the Phase 3 studies, mean IGF-1 increased substantially during the initial 26-week treatment period

At the same time, the number of senescent cells, associated with damage or stress that secretes proinflammatory factors (SASP or senescence-associated secretory phenotype), increases with age in many key tissues, including the kidneys, lungs, blood vessels, and brain SAM may not get the same level of media attention as NAD+, but that doesnt stop it from being less useful: S-adenosylmethionine, or SAM, has been used for several years in the treatment of hepatic conditions and osteoarthritis and more recently in the treatment of clinical depression
