Sermorelin, Tesamorelin, and Ipamorelin: How to Choose the Right Growth Hormone Peptide January 15, 2026 Peptide therapy has opened the door to a new way of supporting the bodys natural ability to heal, recover, and adapt over time
Ghrelin Receptor (GHS-R1a) Selective Activation Ipamorelin acts as a highly selective agonist of the growth hormone secretagogue receptor (GHS-R1a), mimicking the natural hormone ghrelin without affecting other pituitary hormone secretion: Selective binding to GHS-R1a receptors without stimulating ACTH, cortisol, or prolactin release Rapid onset of growth hormone pulse generation (peak levels within 40-60 minutes) No significant effect on appetite stimulation unlike other ghrelin mimetics Preserved feedback regulation through endogenous growth hormone-releasing inhibitory mechanisms Research indicates that ipamorelin releases growth hormone with potency and efficacy similar to GHRP-6 (EC50 approximately 1.3 nmol/L) but with superior selectivity for growth hormone secretion
