Ipamorelin Dosage: Why There Is No Established Dose
The only peptide here still sitting in FDA's category 2 list, under the 503B interim policy — added September 29, 2023 and still listed as of the page's April 2026 revision.
Where Ipamorelin stands with the FDA
“A study published in literature identified serious adverse events including death when ipamorelin was administered intravenously for improving gastric motility.”
There is no dose to report
No FDA-labeled dose exists, and we found no published human dosing we were willing to present as a protocol. FDA states it lacks sufficient information to know whether ipamorelin would cause harm via several injectable routes.
We would rather tell you this than publish a number. Pages that rank for “ipamorelin dosage” routinely state precise-looking figures with no citation attached to them. A number without a source is not more useful than an honest absence — it is less useful, because it looks like it came from somewhere.
Convert your prescribed dose to syringe units
If a clinician has prescribed Ipamorelin for you, the number that matters next is how far to draw the syringe — and that depends on how much bacteriostatic water went into the vial, not on the peptide itself.
This converts a dose your prescriber has already given you into a volume and a number of units on a U-100 insulin syringe. It does not suggest a dose, and it does not tell you whether a peptide is appropriate for you. Most research peptides have no FDA-approved dosing, so there is no “standard” number for us to fill in. Doses here are in micrograms (mcg) — confusing mcg with mg is a 1,000-fold error and the single most common way people get this wrong.
Enter the dose your prescriber gave you, in micrograms, to see the volume and syringe units.
Your 5 mg vial in 2 mL of bacteriostatic water is —.
