quick one you can absolutely just always use 2ml, and honestly most of us should
dead space in a standard insulin syringe hub is small but it is not nothing over a month, still working it out
if the maths gives you 13.7 units, change the volume. do not try to hit 13.7
the meniscus thing is real. read it at eye level or you are guessing by a unit either way
it should be completely clear with no floaters. cloudy means stop
check your maths
too dilute imo

took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience
sorry to jump in 10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100
