Reminder: this board does maths, not dosing. Nobody here tells another member what amount to take.

Why "more water" keeps confusing people, including me for a month.
The vial contains a fixed amount of peptide. Water changes nothing about that amount. What it changes is concentration, and concentration is the divisor between the dose you want and the volume you draw.
So doubling the water halves the concentration and doubles the units for the same dose. Nothing is diluted in any sense that matters; you are simply reading a bigger number off the same barrel. Pick the water volume that puts your usual dose on a whole number of units and life gets easier.

Correction: that gives 100 units, not what you have written. 5mg into 2mL is 2.5mg/mL and the division follows from there.

Bacteriostatic or plain sterile water?

Working has to be shown on arithmetic posts. Added a note asking for it rather than removing this one.

The arithmetic in full: concentration is mass over volume, so 5mg into 1mL gives 5mg/mL. A U-100 syringe is graduated at 100 units per millilitre, so 1mg is 1 divided by 5 millilitres, which is 20 units.

This. Showing the working is the fastest way for somebody else to spot the mistake.

That is a non-fasting value and the interval you are comparing it against is a fasting one.

Corrected the concentration in the title, which contradicted the body. Nothing else touched.

That is sterile water, not bacteriostatic. Same appearance, different product, and it matters for a multi-draw vial.
