Reconstitution
From a vial label to a syringe reading: the calculator, the cross-compound chart, the worked examples and the terminology guide. Concentration is vial amount divided by water volume; everything on this page is that division and its consequences. Research use only.

Reconstitution Math Examples
Worked examples from label to syringe, step by step, in the same arithmetic the calculators run.
How the math works
The three formulas every page here uses, the constants they rest on, and the sources for them.
How much water, and how many units
Reconstitution arithmetic is three divisions and nothing else. The concentration is the vial amount divided by the water volume: 10 mg in 2 mL is 5 mg/mL, which is 5,000 mcg/mL. What one syringe mark holds is that concentration divided by a hundred, because one U-100 unit is a hundredth of a millilitre — so 5,000 mcg/mL puts 50 mcg in a unit. And the units for any amount are the amount divided by that figure: 250 mcg is five units at 50 mcg a unit.
Two consequences follow, and between them they answer most of what is asked about a vial. The water volume never changes how much peptide the vial holds, so it never changes how many amounts the vial contains — it changes only how many units each one reads, which is what decides whether a draw can be measured accurately. And a unit figure quoted without its vial size and its water volume cannot be converted back into micrograms by anyone, which is why every table in this section carries all three.
What is not here: how to mix a vial, how to store it afterwards, and how long a reconstituted vial keeps. Those are on medibact.com’s reconstitution guide, which covers the procedure itself. This section is the arithmetic and the per-compound figures.
Every compound, vial sizes and unit size
The 52 compounds the calculator is preset for, with the vial sizes each preset carries and what one U-100 unit holds if that vial is reconstituted in 1 mL. 28 have a written page with the sourced figures; the rest link to their calculator, which runs the same arithmetic for any volume.

The unit column is the quickest read in the table. A vial whose figure is large — 500 mcg a unit for a 50 mg vial in 1 mL — puts a small amount inside one or two marks on the syringe, where a half-mark misreading is a large fraction of it; a vial whose figure is 1 or 2 mcg puts an ordinary amount at tens of units. More water moves a compound down that column without changing anything in the vial. The cross-compound version of the same arithmetic, at 1, 2 and 3 mL for every common vial size, is the reconstitution chart.
