Overview of Sermorelin
Stimulates natural pulsatile growth hormone release from the pituitary while preserving physiological feedback mechanisms.
Binds to GHRH receptors on pituitary somatotroph cells, triggering cAMP-mediated signaling cascades.
Stimulates natural pulsatile release of growth hormone, preserving physiological secretion patterns and negative feedback.
Increases hepatic IGF-1 production, mediating anabolic effects on muscle, bone, and connective tissue.
Maintains hypothalamic-pituitary axis feedback (unlike exogenous HGH), reducing risk of pituitary suppression.
Short half-life (~10-20 minutes) requires bedtime administration, augmenting the natural nocturnal GH surge
