Ipamorelin

Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It stimulates growth hormone release with minimal effect on cortisol or prolactin, making it one of the cleaner GH-releasing peptides available.

Quick facts

Half-life
~2 hours
Administration
Subcutaneous injection
Primary use
Growth hormone release, recovery

How it works

Ipamorelin mimics ghrelin and binds to the GHS-R1a receptor in the pituitary gland, triggering a selective pulse of growth hormone. Unlike other GHRPs, it does not significantly raise cortisol or prolactin levels.

Reported benefits

  • Clean, selective growth hormone release
  • Improved muscle recovery and lean mass
  • Better sleep quality and depth
  • Minimal side effect profile compared to other GHRPs

Typical dosing protocol

Dosing

100–300 mcg per injection, 2–3x daily (often combined with CJC-1295)

Cycle length

8–12 weeks
