Ipamorelin is a synthetic five-amino-acid peptide classified as a growth hormone secretagogue and a ghrelin-receptor agonist. In studies it stimulates the pituitary gland to release growth hormone. It is sold as a research chemical and is not an approved medicine.

How does ipamorelin differ from other GH secretagogues?

Ipamorelin is described as relatively selective: in early studies it stimulated growth hormone release with comparatively little increase in cortisol and prolactin versus some other secretagogues. That selectivity is a key reason it appears so often in peptide research discussions.

What is ipamorelin studied for?

Ipamorelin has been investigated in pharmacology research for growth hormone release and, historically, for conditions like post-operative gut motility. It is not an approved treatment, and human data are limited.

Is ipamorelin FDA-approved?

No. Ipamorelin is not FDA-approved for any indication. It is sold only as a research chemical, and the FDA has flagged several peptide growth hormone secretagogues as unsuitable for compounding.

Is ipamorelin banned in sports?

Yes. Growth hormone secretagogues and their releasing peptides, including ipamorelin, are prohibited at all times in sport by the World Anti-Doping Agency.

What are the reported side effects of ipamorelin?

Reported anecdotal effects include water retention, headache, lightheadedness, and injection-site reactions. Human safety data are limited and long-term effects are unknown, so a licensed clinician should be consulted before any use.

How is ipamorelin reconstituted?

Lyophilized ipamorelin is typically reconstituted with bacteriostatic water added slowly down the vial wall and gently swirled until the solution is clear. See the steps below and our full reconstitution guide.

Ipamorelin dosage

Ipamorelin comes in 5 mg and 10 mg vials. Pick your vial to see exactly how much bacteriostatic water to add and how many insulin units to draw. Reconstitution math and unit conversions for the 5 mg and 10 mg vials. Ipamorelin has no validated human dose; the usage pattern shown is community-reported and anecdotal.

At 2 mL water: 2.5 mg/mL

Calculate for your vial

Enter the mg on your Ipamorelin vial, the bacteriostatic water you added, and your target dose — it works out the exact units to draw on a U-100 insulin syringe, for whatever you personally have.

Check the decimal. A misplaced decimal point here is a 10× dosing error. Re-read every number, and confirm your dose with a licensed clinician before you draw.

Personalize by body weight & height

Ipamorelin · tailored to you

Optional

Growth-hormone release scales with body size, so bigger people tend to sit toward the higher end. The usual range is about 200–300 mcg; the numbers below estimate that for your weight.

Typical flat community dose: 200 mcg – 300 mcg per injection.

Research cites ~1–2 mcg/kg as the practical band, but there is no validated per-kg use instruction — this is an anecdotal estimate, not a recommendation. Many people just use a flat ~200–300 mcg.

Source: Human GH PK studies — ~1–2 mcg/kg cited as clinically practical. Educational only — not medical advice and not a dosing recommendation. Any dosing decision belongs with a licensed clinician.

Reconstitution figures are deterministic measurement math. WikiPeps is a community reference and sells injection supplies only — never peptides. Nothing here is medical advice.
