Sermorelin is a synthetic analog of the first 29 amino acids of growth hormone releasing hormone (GHRH 1-29). Unlike HGH, it stimulates the pituitary to produce GH in a pulsatile, physiological manner rather than delivering exogenous GH. FDA-approved for pediatric GH deficiency diagnosis and treatment; widely prescribed off-label by anti-aging and longevity physicians. Advantages over exogenous HGH: preserves pituitary function, more physiological GH pulses, lower feedback suppression, significantly lower cost. Often combined with GHRP-2 or ipamorelin to maximize GH pulse amplitude via dual-axis stimulation.

Plain-English Snapshot

Sermorelin is currently categorized as a gh secretagogue compound.

Evidence scoring has not been fully computed yet, so interpret this profile as preliminary.

Safety scoring is incomplete. Start conservatively and monitor carefully.

Core mechanism

GHRH receptor agonist in anterior pituitary somatotrophs; increases cAMP via Gs-coupled receptor; amplifies pulsatile GH release; preserves hypothalamic-pituitary axis
