Ipamorelin dosage chart: how many units on the syringe

How to read the chart

The table covers a 5 mg Ipamorelin vial, the most commonly listed size, reconstituted with 1 mL, 2 mL, or 3 mL of bacteriostatic water. Find your water volume, then find the dose in milligrams. The last column is the mark you draw to on a U-100 insulin syringe.

The first thing to notice is that the units column changes even when the dose does not. A 0.1 mg dose is 2 units in one column and 6 units in another. Nothing about the amount of peptide changed. Only the amount of water it is dissolved in changed. Units measure volume, not drug.

The second thing to notice is that the relationship is strictly proportional in both directions. Doubling the water doubles the units. Tripling the dose triples the units. There is no rounding trick or correction factor. If your own numbers do not behave this way, you have made an arithmetic error somewhere.

The third thing: the 3 mL column produces the largest unit numbers. Larger numbers are easier to draw accurately, because the same physical wobble at the plunger represents a smaller fraction of the total. That is the practical argument for diluting more, and it is a measurement argument, not a biological one.

The arithmetic behind the numbers

A U-100 insulin syringe is graduated so that 100 units equals 1 mL. One unit is therefore one hundredth of a millilitre. That is the only conversion the syringe performs. It has no knowledge of what is inside it.

Concentration is the vial contents in milligrams divided by the water added in millilitres. The chart shows this directly: the 5 mg vial reaches 5 mg/mL with 1 mL of water, 2.5 mg/mL with 2 mL, and 1.67 mg/mL with 3 mL. Once you know the concentration, the volume you need is the dose divided by that concentration, and the units are that volume expressed in hundredths of a millilitre.

This is why writing the concentration on the vial label after mixing matters more than remembering the dose. The dose is a number you chose. The concentration is a physical property of the liquid in front of you, and it is the only thing that lets anyone, including you two weeks later, convert milligrams to syringe marks correctly.

Vials other than 5 mg

Ipamorelin is also listed in 2 mg and 10 mg vials. The chart on this page does not cover them, and the unit values in it do not transfer. A vial with a different milligram content, mixed with the same water volume, produces a different concentration, and therefore a different unit count for the same dose in milligrams.

The method is identical, though. Divide the vial's milligram content by the millilitres of water you added to get the concentration. Divide your dose by that concentration to get the volume. Convert that volume into hundredths of a millilitre to get units. Do not assume that because a dose looked like a familiar unit count on a previous vial, the same mark is correct on a new one.

This is the single most common source of error with reconstituted peptides. The vial looks the same, the syringe looks the same, and the label rarely says anything useful after mixing.

What this page does not tell you

There is no reliable human pharmacokinetic data for Ipamorelin available to us. This site therefore makes no statement about its half life, how long it takes to clear, whether it accumulates with repeated administration, or how administrations should be spaced. Any timing schedule you have seen elsewhere did not come from data we can verify.

Ipamorelin is not approved by any regulator for human use. This page is not medically reviewed and does not answer clinical questions. It does not tell you what dose to use, what to expect, what adverse effects occur, or whether the compound is safe or effective. Those questions belong to a clinician with access to your history, and this page cannot substitute for one.

The dose figures in the chart are the amounts that appear in vendor listings. Their presence here reflects what is commonly written down, not an assessment that any of them is appropriate. The arithmetic is correct regardless of whether the dose is.

What we do not know

We hold no reliable human pharmacokinetic data for Ipamorelin, so this site makes no claims about its half life, how long it takes to clear, or how it accumulates. The arithmetic below concerns concentration and volume only.

This page answers arithmetic and handling questions. It does not tell you what dose to take, what to expect, or whether anything is appropriate for you, and there is no medical review behind it.

Common questions

How many units is 0.1 mg of Ipamorelin?

It depends entirely on how much water you added to the vial. From a 5 mg vial in 1 mL of bacteriostatic water, 0.1 mg is 2 units on a U-100 syringe. From the same vial in 3 mL, the same 0.1 mg dose is 6 units.

Does adding more water reduce the dose?

No. The milligrams you draw stay the same if you adjust the unit count correctly. More water lowers the concentration, so the same dose occupies more volume and reads as more units. The chart shows this for the 5 mg vial across 1 mL, 2 mL, and 3 mL.

Which water volume should I use?

This page does not recommend one. The trade-off is mechanical: larger water volumes give larger unit numbers, which are easier to draw precisely, but they use more of the vial's volume per dose. The chart lets you compare the unit counts for 1 mL, 2 mL, and 3 mL before you mix.

Can I use the chart for a 10 mg vial?

No. The chart is calculated for a 5 mg vial only. A 10 mg vial mixed with the same water volume has a different concentration, so the unit counts differ. Recalculate using your vial's milligram content divided by the millilitres of water you added.

How often should Ipamorelin be administered?

We cannot answer that. We hold no reliable human pharmacokinetic data for Ipamorelin, so this site makes no claims about half life, clearance, accumulation, or dosing intervals. This page covers concentration and volume arithmetic only.

What if my syringe is not U-100?

Then the unit marks mean a different volume and the chart does not apply. All figures here assume a U-100 insulin syringe, on which 100 units equals 1 mL. Check the barrel markings before drawing anything.
