View on PubMed [PubMed] Effects of Human Growth Hormone in Men over 60 Years Old (NEJM, 1990) Landmark New England Journal of Medicine clinical study demonstrating that GH administration in men over 60 with low IGF-1 levels reversed body composition changes associated with aging: lean body mass increased, adipose tissue mass decreased, and skin thickness improved over six months
Mechanism Comparison Shared Pathway Both peptides activate GHSR-1a on pituitary somatotrophs, triggering: GHSR-1a Gq/11 PLC IP + DAG intracellular Ca release PKC activation Ca influx GH vesicle exocytosis This is fundamentally different from how GHRH analogs (CJC-1295, Sermorelin) work (GHRHR Gs cAMP PKA), which is why combining either GHRP with a GHRH analog produces synergistic GH release (Veldhuis et al., 2009)
Always swirl gently or roll the vial between your palms to mix
