Electrolytes reconstitution calculator
The short answer
Arithmetic for Electrolytes, not a dose. Enter the vial label, the water you add, and the amount per draw you were given. Research peptides are usually dosed in micrograms.

Dose
This calculator never sets a dose
Research peptides are usually dosed in micrograms.
Preset chips stop unit errors. Type your own amount over any of them.
The tool converts a number you already have. It does not recommend one.
What is in the vial
Common vial sizes.
Bacteriostatic water you add
This changes how concentrated the vial is, not how much peptide is in it. 2 mL is the most common. A standard vial holds about 3 mL; the larger options are for blends and big vials that come in bigger glass.
Amount per draw
Research peptides are usually dosed in micrograms.
Syringe
Insulin barrels are printed in units, where 100 units is 1 mL. Luer barrels are printed in millilitres. Pick the one in your hand.
0.3 mL insulin (30 units, half-unit marks)
Fill in the vial, the water and the amount per draw to see the result.
How the math works for Electrolytes
Concentration equals the amount on the Electrolytes vial label, converted to micrograms, divided by the water volume in milliliters. The volume you draw equals the amount you enter divided by that concentration. Multiplying that volume by 100 converts it to units on a U-100 insulin syringe, and the calculator rounds to the nearest mark your syringe can show. Draws per vial is the total in the vial divided by the amount per draw.
Frequently asked questions
Where do the amount presets on this Electrolytes calculator come from?
Research peptides are usually dosed in micrograms. They exist to stop unit errors, which are the expensive kind here: entering a milligram amount into a field set to micrograms is a thousandfold mistake that a plain calculator answers with a confident zero. They are not a recommendation, and nothing on this page sets an amount for you. Type your own amount over any preset; the arithmetic is the same either way.
What is in a Electrolytes vial before reconstitution?
A lyophilized (freeze-dried) powder. The label states the total amount in the vial, for example a number of mg, not a concentration per mL. Concentration only exists after bacteriostatic water is added: the label amount divided by the water volume. The calculator does that division and then converts the amount you enter into a syringe volume.
How do syringe units work for Electrolytes?
Insulin syringes are marked in U-100 units, where 100 units equals 1 mL, on 0.3, 0.5 and 1 mL barrels. The calculator divides the Electrolytes concentration by 100 to get the amount in each unit, then divides the amount you enter by that figure to get the mark to pull to. The result is rounded to the nearest readable mark on the syringe you choose: half-unit marks on 0.3 mL, 1-unit marks on 0.5 mL, 2-unit marks on 1 mL.
How long can reconstituted Electrolytes be kept?
A multi-dose vial mixed with bacteriostatic water is commonly given a 28-day discard window, the USP 797 default, stored at 2 to 8 C and protected from light. Label the vial with the mix date and discard date; the calculator's print label does this. Cloudiness or floating particles mean the vial should not be used. Manufacturer or pharmacy labeling for Electrolytes takes precedence over the default window.
