How much bacteriostatic water to add and how many units one dose is on an insulin syringe — worked out for 76 injectable peptides, all from the same 10 mg vial so the rows compare.
A peptide arrives as a freeze-dried plug of powder in a sealed vial. Before it can be drawn up it has to be dissolved, and the volume you dissolve it in decides everything downstream: the concentration, how many units on the syringe make one dose, and how long the vial lasts once it is open.
There is no correct volume. Adding 1 ml or 3 ml to the same vial gives the same total amount of peptide — it only moves the decimal point on the syringe. What makes a volume good is whether the resulting dose lands somewhere you can measure accurately. A quarter of a unit is guesswork on gradations printed in whole units; two-thirds of a barrel leaves no room to adjust. The column below picks the smallest volume that puts one dose between about 10 and 50 units, capped at 3 ml because that is what a standard vial holds.
Every row assumes a 10 mg vial and the catalogue's typical dose. Hold a different vial and the arithmetic moves — each row links to that peptide's own calculator, where you can change it.

Every row above says “bac water” and the word is load-bearing. Bacteriostatic water is sterile water with roughly 0.9% benzyl alcohol in it, and that preservative is the only reason a vial can be entered more than once — reconstitute with plain sterile water and you have a single-use vial whether you treat it as one or not. It is also the number to read the “doses per vial” column against: what the difference actually is, who should not use it, and how long each clock runs.
It is one division and one multiplication. Vial mass divided by water added gives the concentration in mg/ml. Dose divided by concentration gives the volume to draw in ml. A U-100 insulin syringe puts 100 units to the millilitre, so multiplying by 100 gives the unit mark. A 10 mg vial in 2 ml is 5 mg/ml; a 250 mcg dose is 0.05 ml; that is 5 units — measurable, but only just, which is why the chart above suggests 3 ml for doses that small.
The reconstitution calculator does it for any combination, the cycle builder runs it across every compound in a cycle and totals the vials, and the half-life table covers the other half of the question — how often, rather than how much.
