Humanin dosage chart: how many units on the syringe

What a unit on a U-100 syringe measures

A U-100 insulin syringe is graduated in insulin units, not in milligrams of peptide. One unit is one hundredth of a millilitre. The barrel measures volume and nothing else.

So every conversion here has two steps. First, concentration: milligrams in the vial divided by millilitres of bacteriostatic water added. Second, volume: your dose in milligrams divided by that concentration, then multiplied by 100 to read it as units.

The consequence is that no dose has a fixed unit value. The same 1 mg of Humanin sits anywhere on the barrel depending on how much water went into the vial. A unit number quoted without the vial size and the water volume is meaningless, which is why the table carries all three columns rather than just the last one.

Three things to notice in the chart

First, water volume scales the units linearly while the dose stays the same. A 1 mg dose from a 10 mg vial moves from 10 units to 20 units to 30 units as the water goes from 1 mL to 2 mL to 3 mL. The amount of Humanin leaving the vial is identical in all three rows. More water does not make a dose weaker, it spreads it across more of the barrel.

Second, one row runs off the end of the syringe. A 5 mg dose from a 10 mg vial in 3 mL comes to 150 units, and a standard U-100 barrel holds 100. That row is flagged because it cannot be drawn in one go. It would need two draws, which doubles the chance of a measurement error, or a different reconstitution volume.

Third, the 3 mL rows give a concentration of 3.33 mg/mL, a repeating decimal rounded for display. The unit figures there are clean whole numbers only because these particular doses divide neatly. Change the dose and you will land between graduation marks.

Combinations the chart does not cover

Humanin is sold in 5 mg and 10 mg vials. The chart here is computed for the 10 mg vial only. A 5 mg vial at the same water volume gives a lower concentration, so any given dose occupies more units. Do not read those figures across from the 10 mg rows.

The dose column reflects amounts that appear in vendor listings, which is 1 mg and 5 mg. A listing is not a recommendation. We report what appears on labels and convert it to syringe units. We take no position on whether either amount is reasonable, and this site has no medical review process that could support such a position.

If your vial, water volume or dose is not shown, the arithmetic is the same. Concentration equals milligrams divided by millilitres. Units equal dose divided by concentration, times one hundred.

What is not known about Humanin

Humanin is not approved by any regulator for human use. There is no approved label, no dosing schedule and no official reconstitution instruction to check numbers against.

We hold no reliable human pharmacokinetic data for Humanin. This site therefore makes no claim about its half life, how long it stays in circulation, how quickly it clears, or whether repeated doses accumulate. We also make no claim about what it does or whether it produces any effect at all.

The table is a volume calculation. It answers how far up the barrel a stated milligram amount reaches at a stated concentration. It does not answer whether that amount should be drawn, how often, or by whom. Those are clinical questions.

One practical note on the arithmetic itself: it assumes the vial contains the labelled amount, that all of it dissolves, and that you added exactly the water volume you intended. None of those is guaranteed with an unapproved compound, and an error in any of them shifts every figure in the chart with no visible sign.

What we do not know

We hold no reliable human pharmacokinetic data for Humanin, 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 1 mg of Humanin?

It depends on how the vial was reconstituted. From a 10 mg vial in 1 mL of bacteriostatic water, 1 mg is 10 units on a U-100 syringe. From the same vial in 2 mL it is 20 units, and in 3 mL it is 30 units. The milligram amount is identical in all three cases.

Why does the 5 mg dose in 3 mL not fit the syringe?

That combination comes to 150 units, and a standard U-100 insulin syringe holds 100 units. It cannot be drawn in a single pull. Using less bacteriostatic water at reconstitution brings the same dose into a single barrel, as the other rows show.

Does adding more bacteriostatic water reduce the dose?

No. It reduces the concentration, so the same milligram dose occupies more units on the syringe. The quantity of Humanin drawn up is unchanged. Water volume changes how the dose is measured, not how much peptide there is.

How often should Humanin be injected?

This site does not answer that. We hold no reliable human pharmacokinetic data for Humanin, so we make no claim about half life, clearance or accumulation, and nothing here supports a dosing frequency. There is no approved label to refer to either.

Can I use this chart for a 5 mg vial?

Not directly. The computed table on this page is for the 10 mg vial. A 5 mg vial at the same water volume has a lower concentration, so the unit figures differ. Recalculate using the vial contents and the water volume you actually used.

Is Humanin safe or effective?

We do not answer that. Humanin is not approved by any regulator for human use, and this page has no medical review behind it. It converts milligrams to syringe units and makes no claim about safety, effect or outcome.
