thursday_thea — do not add more bac water to an already reconstituted vial, you have lost track of the concentration, ymmv 19:30
ollie_orders — is there any reason not to just always use 2ml 20:01
low_and_slow — give it 6 minutes at room temperature before you decide it has not dissolved, i think 20:34
pharmac_pen — can i add more bac water later to a vial ive already reconstituted 22:33

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

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

if i add 3ml to a 40mg vial what concentration am i actually at

⚠️4

one unit is 0.01ml

❤️17

yep 10 units

thats fine

*that should say weekly

benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically

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

do not add more bac water to an already reconstituted vial, you have lost track of the concentration, ymmv

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

label the date too. you will not remember which vial is which by week 4

nobody here should be telling you a dose. we can check your arithmetic, thats a different thing

is there any reason not to just always use 2ml

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

it should be completely clear with no floaters. cloudy means stop

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

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

🧪17

if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space, i could be wrong

bacteriostatic water for anything multi-use. sterile water has no preservative in it at all

how do you all measure a half unit, or do you just not

can i add more bac water later to a vial ive already reconstituted

bac water
