Ipamorelin is a selective pentapeptide growth hormone secretagogue developed to stimulate ghrelin receptor activity with minimal interaction across competing endocrine pathways. It has been studied in growth-axis research for its relationship to pulsatile growth hormone release, recovery signaling, and IGF-1 modulation in controlled experimental settings. Its receptor selectivity distinguishes it from earlier secretagogue compounds associated with broader hormonal activity profiles. Lyophilized powder, 3mL vial. Sold at 10mg per vial.
