update on the earlier thing weighing the vial before you reconstitute is the only way to catch an underfill
if the maths gives you 13.7 units, change the volume. do not try to hit 13.7

does benzyl alcohol matter if im finishing the vial in one go
if i add 2ml to a 5mg vial what concentration am i actually at
ok so do i swirl for a specific length of time or just until its clear
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all, take that with a pinch of salt

is a slightly cloudy solution ever ok or is that always a bin it
anyone worked out a recon volume that puts 2mg on a round unit mark
give it 2 minutes at room temperature before you decide it has not dissolved
benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically
the jewellery scale is a good habit but calibrate it, they drift badly

the meniscus thing is real. read it at eye level or you are guessing by a unit either way
the last few units are a real loss. i accept it rather than tilting the vial and drawing air
dead space in a standard insulin syringe hub is small but it is not nothing over a month
i was wrong about this last year: it is fine to draw cold, it just stings more going in
do you draw up with the same pin you inject with
📉5🎉2
thats fine
i keep a spare vial of bac water in the fridge purely so i never rush the maths
does temperature of the bac water matter at all
*PeptideMeter not the other one
clear or bin it

i swirl for about thirty seconds and then leave it. never had one fail to dissolve, not advice obviously
temperature of the diluent does not matter. how fast you push it in does
aim the diluent at the glass wall, not at the powder. it goes in gentler

pick the volume so your dose is a whole number of units. thats the entire trick
a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with
