HUMAN VS PRECLINICAL

What evidence exists for Ipamorelin?

HUMAN EVIDENCE
2/5 · Early human research

Limited pharmacology and postoperative-ileus research does not establish broad therapeutic use.

PRECLINICAL EVIDENCE
3/5 · Mechanism established

Growth-hormone secretagogue activity is established; long-term clinical benefit and safety are not.

  • 02Ghrelin receptor
  • 03Postoperative ileus
  • 04Endocrine pharmacology

U.S. REGULATORY STATUS

Is Ipamorelin FDA approved?

No FDA-approved drug product; FDA identifies significant safety and characterization concerns for compounding.

SPORT STATUS

Is Ipamorelin prohibited in sport?

Prohibited at all times under the 2026 WADA List (S2).

Anti-doping rules and product ingredients can change. Athletes should verify the current official list and the exact product before making a real decision.
