Ipamorelin is marketed for sleep, recovery and muscle gain by boosting the body's growth-hormone release. Unlike injecting growth hormone, it prompts a hormone pulse. Human research has measured that pulse, not proven those recovery benefits. Serious events, including deaths, were reported during IV research; safety of other injections remains uncertain.

Research & sources
Evidence
Small human pharmacology work shows a short growth-hormone release after exposure. Controlled evidence does not establish meaningful recovery, sleep, fat-loss or lean-mass outcomes.
Interactions & monitoring
Possible fluid retention, numbness, headache and glucose effects; injection-site, sterility, contamination and mislabeling risks; uncertain long-term safety.
Glucose control, edema, neurologic symptoms and injection-site complications; clinical review is appropriate for persistent or severe symptoms.
Medical context
No approved U.S. indication for bodybuilding, general anti-aging, recovery or fat loss. Products sold for those uses are unapproved.
