Ipamorelin
Ipamorelin is a selective compound that triggers growth hormone release, originally developed by Novo Nordisk. It stimulates growth hormone without significantly affecting cortisol or prolactin levels. It has been studied in clinical trials for postoperative recovery.

Overview of Ipamorelin
Selectively activates ghrelin receptors to stimulate growth hormone release without significantly affecting cortisol or prolactin levels.
Selectively binds and activates ghrelin receptor (GHS-R1a) in the pituitary, triggering GH release with high selectivity.
Produces dose-proportional increase in circulating GH levels, allowing for predictable dosing strategies.
Preserves natural pulsatile GH patterns due to short half-life (~2 hours), maintaining physiological rhythm.
Does not significantly increase cortisol, ACTH, or prolactin, a notable difference from other GHRPs.
Minimal appetite stimulation compared to other ghrelin mimetics, which is preferred for those not seeking appetite increase.
Often combined with CJC-1295 or other GHRH analogs (proposed), amplifying GH response through complementary pathways
