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

thats the vacuum
if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space
thats fine
if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way
is there any reason not to just always use 2ml
👍1
anyone else find the 15mg vials harder to get fully dissolved than the small ones
whats the smallest volume you would trust yourself to measure on a u100
right so 15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it
label the vial
dead space in a standard insulin syringe hub is small but it is not nothing over a month
my rule is one concentration for everything so i never have to think about it at 7am
30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right

too dilute imo
one unit is 0.01ml

does benzyl alcohol matter if im finishing the vial in one go
clear or bin it
aim the diluent at the glass wall, not at the powder. it goes in gentler, still working it out

i have never once regretted using a rounder number and a slightly bigger volume
