the insulin syringe thing finally clicked for me and I want to write it down, which sounds obvious until you try to state the evidence for it. Research-use-only material is not approved for human use, so treat everything in this thread as arithmetic about solutions rather than instructions for a person. I keep a…
write the concentration on the vial in marker, that is the whole post
The dead space question sent me down a rabbit hole for a week. It is a fraction of a unit and it is the same every draw.
If your calculation produces a fraction of a unit, the concentration is wrong for your dose. Change the water volume until the numbers land on whole units.
a U-100 syringe reads 100 units to the millilitre, every time
units are a volume on a U-100 syringe, not a dose
more water is not more drug, it is the same drug in a bigger volume
more water is not more drug, it is the same drug in a bigger volume
Disagreeing with this line only: adding more water is not a safety margin, it is a different divisor.
reconstituting at a round concentration makes every later dose easy

Adding one thing — put the date on the label too. Concentration plus date and you can never mix two vials up.
