the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol, thats just me

BB

i use bac water even for a single-use vial because it stings less, which is not the reason it exists

BB

temperature of the diluent does not matter. how fast you push it in does, thats one data point

the powder is stuck to the stopper, do i care

dead space in a standard insulin syringe hub is small but it is not nothing over a month
do not add more bac water to an already reconstituted vial, you have lost track of the concentration

FA

sanity check my maths before i pin myself with something stupid

CH

give it 7 minutes at room temperature before you decide it has not dissolved

U1

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

U1

if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
aim the diluent at the glass wall, not at the powder. it goes in gentler

right so if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space

the last few units are a real loss. i accept it rather than tilting the vial and drawing air, i could be wrong

VB

Inter-lab diff for lot D-0718: 97.4% vs 98.6%. Within expected range.

FA

if i add 0.5ml to a 30mg vial what concentration am i actually at

FA

anyone got a photo of what a properly dissolved vial looks like

my 10mg vial weighed 11.4g on the jewellery scale, is that wrong
