10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use

lyophilised powder is far more robust than people think. it is the solution that is fragile

if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way
10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use

weigh it first

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

bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
the meniscus thing is real. read it at eye level or you are guessing by a unit either way

Batch lookup A-2418: 6 independent reports on file, earliest 2024-11-11.

benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically, ask me again in a month

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

aim the diluent at the glass wall, not at the powder. it goes in gentler

check your maths

i was wrong about this last year: it is fine to draw cold, it just stings more going in

thats 5mg/ml

one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that

it foamed. is it ruined

foam is bad

not sterile water

do you let it come to room temp before drawing or draw it cold

is it normal for the cake to look slightly collapsed on one side

give it 6 minutes at room temperature before you decide it has not dissolved

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

does benzyl alcohol matter if im finishing the vial in one go

coming back to this is the meniscus reading actually a real source of error or am i overthinking

dead space

nope, redo it
