Ipamorelin is a small peptide with a short history and a clear regulatory position: it was developed by a major drug company, never approved anywhere, and today exists only as a research compound. The maths on this page is straightforward — a 5 mg vial and 2 mL of water is the combination most guides use as their example, and this page starts there.
What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide — a chain of just five amino acids — that selectively activates the ghrelin receptor (GHS-R1a), making it a growth hormone secretagogue: a compound that signals the pituitary gland to release growth hormone. It was developed by Novo Nordisk in the 1990s under the code NNC 26-0161. Development for postoperative ileus reached Phase 2 and was discontinued after the trial did not meet its primary endpoint, and no active clinical development programme was identified as of August 2026.
It is not approved by the FDA for any indication, anywhere. There is no FDA-approved ipamorelin product and no approved label. The FDA placed ipamorelin acetate in Category 2 (bulk substances that may present significant safety risks) in September 2023, and in October 2024 its compounding advisory committee voted 0 in favour, 12 against (1 abstention) on adding it to the 503A bulks list. It is not on the 503A or 503B bulks lists, and WADA prohibits it at all times under S2.
The vial maths.
Vials are sold as 2 mg, 5 mg and 10 mg, with 5 mg the size most reconstitution guides use as their default example.
Worked example — 5 mg vial, 2 mL of BAC water, example dose 300 mcg (0.3 mg):
- Concentration: (5 × 1,000) ÷ 2 = 2,500 mcg/mL
- Each unit holds 2,500 ÷ 100 = 25 mcg
- Units for the example dose: 300 ÷ 25 = 12 units (0.12 mL)
- Doses in the vial: 5,000 ÷ 300 = 16.7 doses (about 16 full doses)
If your dose is written as 0.3 mg, that is 300 mcg — multiply by 1,000, or tap the mg toggle and type 0.3 directly. The same 5 mg vial in 1 mL of water would be twice as strong per unit, so the same example dose would take 6 units instead of 12. The water volume is half the calculation.
Storage (commonly cited):
Unmixed powder refrigerated at 2–8 °C, or frozen at −20 °C for longer storage, protected from light. Once mixed, refrigerate at 2–8 °C, protect from light, do not re-freeze. Sources commonly cite around 28 days (some say 21 days, some 30 days, one says 4–6 weeks) — no published stability study for home-reconstituted ipamorelin was found, so treat any window as a planning figure.
FAQs
How many units do I draw for my ipamorelin dose?
Work out the concentration first: a 5 mg vial in 2 mL is 2,500 mcg/mL, so each unit holds 25 mcg and your units = your dose in mcg ÷ 25. Different vial or water? The calculator recomputes instantly.
My dose is written as 0.3 mg. How do I enter that?
0.3 mg is 300 mcg (multiply by 1,000), or tap the mg toggle on the dose field and type 0.3. At 2,500 mcg/mL that example dose is 300 ÷ 2,500 = 0.12 mL = 12 units.
Does the amount of water change my ipamorelin dose?
It changes the concentration, not the total peptide. The same 5 mg vial is twice as strong per unit in 1 mL as in 2 mL, so your unit count halves. Recalculate whenever your mix changes.
Is ipamorelin FDA-approved?
No — not for any indication, anywhere. It is sold as a research chemical.
