Preclinical — Animal / cell-model data onlyWhat it is
A selective ghrelin receptor agonist studied for its effect on pulsatile growth hormone release. Clinical development was discontinued.
Ipamorelin is a selective ghrelin-receptor agonist that produces a clean GH pulse with minimal effect on cortisol or prolactin. Clinical development was discontinued.
Research context
Studied in relation to:
- GH-release research
Points in its favour in the literature:
- Selective, minimal cortisol/prolactin effect
- Predictable short pulse
Caveats and unknowns:
- Clinical development discontinued
- Limited long-term human data
- Prohibited in sport
Handling & reference data
Route in published researchSubcutaneous injection is the route most commonly described in the research literature.
Reported half-lifeshort (~2 h)
Published clinical / research context (not instructions)Reported research ~100–300 mcg per dose, 1–3× daily.
Storage (lyophilised)Lyophilised (freeze-dried) powder: refrigerate at 2–8 °C short-term, or freeze at −20 °C or below for long-term storage. Keep sealed and out of light.
Reconstituted solutionOnce reconstituted: keep refrigerated (2–8 °C), protect from light, do not freeze. With bacteriostatic water, commonly used within ~4 weeks; with plain sterile water, within ~24–48 h.
Worked reconstitution example (arithmetic only)e.g. 5 mg vial + 2 mL → 2.5 mg/mL.
