bacteriostatic water for anything multi-use. sterile water has no preservative in it at all, still working it out
weigh it first
one unit is 0.01ml
if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space
yep 10 units
do you let it come to room temp before drawing or draw it cold

give it 9 minutes at room temperature before you decide it has not dissolved

update from 15 months ago: switched to a single concentration and have not miscalculated since

sorry to jump in if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
why does everyone say 2ml specifically and not 1ml
not sterile water
nope, redo it
10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100

is it worth buying a 3ml syringe for the diluent or is the insulin one fine
30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right

does benzyl alcohol matter if im finishing the vial in one go
20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
