Growth Hormone Secretagogues and Lipolysis Pathways
Growth hormone influences lipid metabolism through multiple mechanisms. GH stimulates lipolysis (fat cell breakdown) through hormone-sensitive lipase activation and inhibits lipogenesis (fat synthesis) through effects on acetyl-CoA carboxylase. The hormone acts on adipocyte GH receptors to mobilize triglycerides from lipid droplets. This mechanism has prompted research into growth hormone secretagogues as compounds studied for fat metabolism effects. The best peptides for fat loss in this class function by elevating endogenous growth hormone secretion, thereby producing similar metabolic consequences to exogenous GH administration while relying on the body's natural feedback mechanisms.
