10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100

Highlights from this day
- mcg_not_mg — the last few units are a real loss. i accept it rather than tilting the vial and drawing air temperature of the diluent does not matter. how fast you push it in does 17:59
- VialBot — Recon calculator: 30mg in 5ml = 2mg/ml. 18:27
- cold_pack_carla — follow up 30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right 18:30
- cold_pack_carla — my vial pulled the water in on its own, is that the vacuum or did i do something 19:39
- rotate_the_site — temperature of the diluent does not matter. how fast you push it in does if you cannot read the mark confidently, your volume is too small. redo it at a lower… 20:46
not sterile water
10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use, thats one data point
dead space in a standard insulin syringe hub is small but it is not nothing over a month
clear or bin it
unrelated but bac water or sterile water for something im going into weekly for 5 weeks
check your maths

dead space
swirl dont shake
nope, redo it
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all

yep 10 units
follow up 15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it, for what its worth
my vial pulled the water in on its own, is that the vacuum or did i do something

foam is bad

is it normal for the cake to look slightly collapsed on one side
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing

the jewellery scale is a good habit but calibrate it, they drift badly

weighing the vial before you reconstitute is the only way to catch an underfill, i could be wrong
took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience
temperature of the diluent does not matter. how fast you push it in does
if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way
if the maths gives you 13.7 units, change the volume. do not try to hit 13.7
you can absolutely just always use 2ml, and honestly most of us should, still working it out
