SERMORELIN 10MG | Growth Hormone Release

Sermorelin 10mg is a research-grade growth-hormone-releasing hormone analog studied for GH secretion, IGF-1 signalling, body composition and sleep-related GH pulses. This 3 ml vial containing 10 mg presentation is intended for laboratory investigation of longer-duration GHRH receptor studies. Sermorelin binds the GHRH receptor on anterior pituitary somatotrophs and stimulates GH synthesis and release through cAMP and calcium-dependent signalling. Its 29-amino-acid structure retains the receptor-binding domain of native GHRH while being less susceptible to rapid degradation.

The result is a physiological, pulsatile GH signal rather than constant exposure. Walker (Clinical Interventions in Aging, 2006) described sermorelin as a diagnostic and research tool for GH reserve and as a physiological alternative to exogenous GH. Dose-ranging work has shown that GH and IGF-1 responses vary with age, adiposity and gonadal steroid status. The 10 mg presentation supports longer treatment arms, repeated testing and studies of body composition, bone turnover and sleep-associated GH release. It is also used to compare GHRH agonism with ghrelin-receptor agonism.

A larger vial reduces the number of reconstitutions in multi-week protocols and allows matched aliquots across dose groups. Store reconstituted solution at 2-8C and use it within the stability window, because sermorelin can degrade rapidly at room temperature. Store the lyophilised powder at -20C, protect it from light, and reconstitute with bacteriostatic water or an appropriate laboratory buffer according to institutional protocols. Prepare aliquots before freezing and avoid repeated freeze-thaw cycles, which degrade peptide structure and reduce reproducibility.

Open questions include the optimal dosing frequency for sustained IGF-1 elevation, the interaction with gonadal steroids, and whether long-term GHRH stimulation improves body composition without adverse effects on glucose metabolism.
