Turn a vial and a volume of bacteriostatic water into the exact mark to draw to. Concentration, millilitres, syringe units and administrations per vial, calculated live.

A lyophilized peptide vial arrives as dry powder. The label tells you how many milligrams are inside, but not what to draw, because that depends on a decision you have not made yet: how much bacteriostatic water to add.
Once you choose that volume, three numbers follow automatically. Concentration is the peptide divided by the water. Draw volume is your target amount divided by that concentration. Syringe units are the draw volume scaled to your syringe, where a U-100 barrel marks 100 units per millilitre.
The arithmetic is simple. The errors are not, because the units keep shifting: labels in milligrams, targets in micrograms, volumes in millilitres, syringes in units. Most mistakes are conversion slips, not maths failures. That is the specific problem this tool removes.
Each page loads with typical vial values for that compound, plus reported ranges and cited research.
