Half the questions we get are the same question: how many units is this on the syringe. Vial size, water and amount in; the number to draw to, how many draws are in the vial, and what each one costs, out. Save it to your phone and it works with no signal.
Not which compound, not which vendor — how many units. The vial is labelled in milligrams, the amount people talk about is often in micrograms, and the syringe is marked in units of volume. Three systems and a thousand-fold trap between two of them. This keeps them straight, tells you when a dose lands between tick marks, and tells you when you have added so little water the dose is too small to read.

Arithmetic, not advice. This tool converts a vial size, a water volume and an amount into a syringe reading. It does not recommend any compound, amount, or use. Quick-fill amounts are numbers people commonly search for, not suggestions. Compounds are sold by third-party suppliers as research materials. Confirm every number against the protocol you were given.
