A selective growth-hormone secretagogue with a clean side-effect profile.
Last reviewed Oct 7, 2026 · How we rate evidence · Report an error
Ipamorelin triggers the pituitary to release growth hormone (GH) by activating the ghrelin receptor, without notably raising cortisol or prolactin. It reached human trials (post-surgical bowel recovery) but was never approved.
Ghrelin-receptor (GHS-R1a) agonist producing a short, pulsatile GH release. Often paired with a GHRH analog (CJC-1295, sermorelin) for a stronger combined pulse.

Phase 2 human trials for postoperative ileus; GH-release effects are well documented in humans. How we rate evidence
Dose-dependent GH release confirmed in human pharmacology studies.
Frequently reported when dosed before bed.
Leaner mass / less fat reported; controlled evidence is limited.
Seen in animal studies.
“Anecdotal” means reported by users, not shown in controlled trials. Sources
Not recommendations. These are commonly cited ranges, shown so you can see what real-world use looks like.
| Plan | Dose | Frequency | Duration | Route |
|---|---|---|---|---|
| Standard Inject on an empty stomach (2h after food); fasted state improves GH release. | 200 mcg | 1–3× daily (often bedtime) | 8–12 weeks | Subcutaneous |
| Higher | 300 mcg | 2× daily | 8–12 weeks, then break | Subcutaneous |
Set up for Ipamorelin. Switch vial size any time. Educational math only, not dosing advice.
At a common mix of 5 mg of Ipamorelin in 2.5 mL of water (2 mg/mL), these commonly reported doses come to the following on a U-100 insulin syringe (100 units = 1 mL). They are examples of the arithmetic, not recommendations.
| Reported plan | Dose | Draw to | Volume |
|---|---|---|---|
| Standard | 200 mcg | 10 units | 0.1 mL |
| Higher | 300 mcg | 15 units | 0.15 mL |
Concentration (mg/mL) = vial mg ÷ mL of water; units = dose (mg) ÷ concentration × 100. A different vial size or amount of water changes every number above.

Powder
Freezer / fridge
Keep sealed vial in the freezer (−20 °C) for long-term storage; fridge (2–8 °C) is fine for a few weeks. Keep dry and out of light.
After mixing
~30 days
Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light.
Travel
Keep cool
Short trips at room temperature are generally fine for powder; keep mixed vials cold.
Investigational only. Not an approved drug; compounding status has changed over time, so verify with the FDA 503A categories page.
Regulations change often — verify with the FDA, EMA, MHRA, Health Canada, TGA and WADA before acting.
In studies, ipamorelin is notable for not meaningfully raising cortisol or prolactin at normal doses.
Natural GH peaks during deep sleep; a fasted pre-sleep dose may reinforce that.
It depends on the mix. At a common mix of 5 mg of Ipamorelin in 2.5 mL of water (2 mg/mL), 200 mcg is 10 units (0.1 mL) on a U-100 insulin syringe. The formula is dose in mg ÷ concentration in mg/mL × 100. Change the vial size or water in the calculator and the units update. This is math, not a dose recommendation.
Bacteriostatic water (0.9% benzyl alcohol) — allows multiple draws from one vial. A common mix is 5 mg + 2.5 mL, which gives 2 mg/mL. Less water makes a stronger mix and fewer units per dose; more water makes a weaker mix and more units. Pick the amount that lands your dose on an easy-to-read line.
Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light. Plan on about 30 days once it is mixed, and discard it sooner if it turns cloudy or has particles. The calculator shows how long a vial lasts at your dose and flags a vial that outlasts its shelf life.
Evidence rating (3/5): Phase 2 human trials for postoperative ileus; GH-release effects are well documented in humans.
