#30Growth Hormone & Body Composition
Ipamorelin
selective ghrelin/growth-hormone-secretagogue receptor agonist
Evidence: other human studyReviewed 2026-07-25
Investigated uses
- No adequately documented human investigated use for the exact catalog identity/formulation was identified; any vendor-promoted goals were excluded from evidence grading.
Mechanism and hypotheses
- Ipamorelin is a synthetic pentapeptide ghrelin-receptor agonist with growth-hormone-releasing activity.
- Hypothesized: Claims of selective recovery, sleep or body-composition benefit are not supported by an approved indication or robust outcome trial.
Human evidence
- No qualifying controlled human efficacy study for the exact catalog identity/formulation was identified in this review. Limitations: This is a bounded search conclusion, not proof that no report exists; identity, language and indexing limitations may apply.
Safety highlights
- Human route-specific safety is limited; endocrine and gastrointestinal effects may occur.
- FDA notes serious adverse events, including deaths, in an intravenous gastrointestinal-motility study; causality and relevance to other routes are uncertain.
Regulatory context
No FDA-approved ipamorelin drug was identified; FDA lists ipamorelin among substances presenting significant compounding safety concerns.
