Ipamorelin
📝 LAB NOTES
Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue studied for its activity at the growth hormone secretagogue receptor (GHS-R1a), also known as the ghrelin receptor. Research has explored its ability to stimulate growth hormone (GH) release and its potential influence on endocrine signaling, GH-related pathways, body composition, bone metabolism, tissue recovery, and other biological processes associated with the growth hormone axis.
Ipamorelin is of particular research interest because early preclinical studies characterized it as a selective growth hormone secretagogue with less stimulation of adrenocorticotropic hormone (ACTH) and cortisol pathways than some earlier growth hormone-releasing peptides under the experimental conditions studied.
TARGETED RESEARCH USE
Growth hormone secretion, GHS-R1a and ghrelin receptor signaling, endocrine regulation, GH and IGF-1-related pathways, pulsatile growth hormone research, body composition, bone metabolism, muscle-related biological processes, tissue recovery pathways, protein metabolism, and age-related changes in growth hormone signaling.
