Sermorelin Acetate – 10mg

Sermorelin Acetate—also known as GRF (1-29) amide—is a synthetic, amidated 29-amino acid peptide that corresponds to the functionally active amino-terminal segment of endogenous human Growth Hormone-Releasing Hormone (GHRH). Stabilized as an acetate salt, it represents the shortest fully functional fragment of native GHRH capable of binding to and activating pituitary receptors. In preclinical research models, Sermorelin Acetate is widely used to study the regulation of the hypothalamic-pituitary-somatic axis, offering an experimental framework to observe growth hormone production that is constrained by natural negative feedback mechanisms.

Key Features & Characteristics

• Mechanism of Action: Binds selectively to GHRH receptors on anterior pituitary somatotrophs, activating the adenylate cyclase–cAMP–PKA signaling cascade to stimulate growth hormone release. [1]
• Physiological Feedback: Preserves native hypothalamic-pituitary feedback loops; its effects are regulated by somatostatin, avoiding the receptor down-regulation or excessive surges associated with exogenous growth hormone. [1, 2]
• Short Pharmacokinetic Half-Life: Exhibits rapid clearance from systemic circulation, with an experimental half-life of approximately 11–12 minutes, making it ideal for tracking acute pituitary response dynamics. [1, 2]
• Physical Form: Produced via high-fidelity peptide synthesis and supplied as a highly stable, white lyophilized powder requiring precise fluid reconstitution. [1, 2]

Primary Research Applications

• Somatotropic Secretion & Pulsatility: Extensively utilized to map the physiological mechanisms of pulsatile growth hormone secretion and to assess the functional secretory reserve of the pituitary gland. [1, 2]
• Anabolic Metabolism & Tissue Repair: Investigated for its downstream capacity to elevate hepatic Insulin-like Growth Factor 1 (IGF-1) levels, which influences muscle protein synthesis, nitrogen retention, and connective tissue repair. [1, 2]
• Body Composition & Cellular Aging: Studied in metabolic and gerontological models to observe adjustments in the fat-to-lean mass ratio, bone mineral density dynamics, and the modulation of age-related somatotropic axis decline. [1, 2]
