An Aib-His-D-2-Nal-D-Phe-Lys-NH2 pentapeptide that potently and selectively activates the growth hormone secretagogue receptor (GHS-R1a) in pituitary somatotroph cells to drive growth hormone release with a receptor selectivity profile that eliminates the prolactin and cortisol co-secretion characteristic of first-generation GH secretagogues including GHRP-6 and GHRP-2 and making it an indispensable research tool for studying GHS-R1a receptor pharmacology and Gq/11-calcium signal transduction, the structural determinants of GHS-R1a subtype selectivity separating GH release from prolactin and cortisol co-stimulation, pituitary somatotroph cell biology and selective GH secretory mechanisms, the complementary and synergistic regulation of GH release by GHRH and selective GHS-R1a agonists, IGF-1 axis downstream biology under selective GH stimulation, the comparative pharmacology of selective versus non-selective growth hormone secretagogues across the GHS-R1a agonist class, and the ghrelin axis biology of selective receptor engagement without the endocrine co-secretion confounds of first-generation GH secretagogue research, Researchers and institutions across Ireland can source verified, research-grade Ipamorelin directly from our Irish peptide supply, with domestic-speed dispatch and complete batch documentation

There was no increase in adverse digestive symptoms in the cinnamon groups, compared with placebo (Zelicha 2024)
While there are several ways you can improve your sleep quality, such as not drinking caffeinated beverages late in the day or avoiding bright screens a few hours before bedtime, glycine may also help
