Full research summary5 citations

Ipamorelin is a selective GHS-R1a agonist and the cleanest of the growth hormone releasing peptides. It drives a natural GH pulse without dragging cortisol, prolactin, or appetite up with it, which is why it became the default GHRP in CJC-1295 research stacks. Human pharmacokinetics are already established in published clinical work.

Storage & handling

Freeze-dried at -4F; in solution 36-46F and best used within 28 days, after which potency gradually fades (structure-based estimate, no published data).

Research cautions

Contraindicated where there is active malignancy of any kind, since GH/IGF-1 signaling can promote tumor growth; sustained GH-axis stimulation also worsens insulin resistance.
