took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience, ill dig out the number

temperature of the diluent does not matter. how fast you push it in does

you can absolutely just always use 2ml, and honestly most of us should

im getting bubbles in the barrel every single time, what am i doing wrong

BR

unrelated but the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol

quick one coming back after 8 months, has the pinned recon volume advice changed

not sterile water

foam is bad

the powder is stuck to the stopper, do i care

i write the mg/ml on the vial with a sharpie the moment i reconstitute it

pick the volume so your dose is a whole number of units. thats the entire trick

sorry to jump in the jewellery scale is a good habit but calibrate it, they drift badly, from memory

is a slightly cloudy solution ever ok or is that always a bin it

dead space in a standard insulin syringe hub is small but it is not nothing over a month

30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right

round numbers

20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
