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

Highlights from this day
- spare_vial — benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically 16:24
- lean_mass_lex — i swirl for about thirty seconds and then leave it. never had one fail to dissolve 15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it 16:27
- mg_per_ml — is it worth buying a 3ml syringe for the diluent or is the insulin one fine 17:32
- a1c_lag — update from 26 months ago: switched to a single concentration and have not miscalculated since 19:41
read it at eye level
label the date too. you will not remember which vial is which by week 5
not sterile water
does it matter if i inject the bac water straight at the powder
lyophilised powder is far more robust than people think. it is the solution that is fragile
too dilute imo

if the maths gives you 13.7 units, change the volume. do not try to hit 13.7
i swirl for about thirty seconds and then leave it. never had one fail to dissolve
15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it
for the archive i use bac water even for a single-use vial because it stings less, which is not the reason it exists
my rule is one concentration for everything so i never have to think about it at 7am
do not add more bac water to an already reconstituted vial, you have lost track of the concentration
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing
30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right
is it worth buying a 3ml syringe for the diluent or is the insulin one fine

do i swirl for a specific length of time or just until its clear
[edited]temperature of the diluent does not matter. how fast you push it in does
right so is the meniscus reading actually a real source of error or am i overthinking
how much do i lose to dead space with a 30G pin
label the vial
