Highlights from this day
- tga_notice — i was wrong about this last year: it is fine to draw cold, it just stings more going in 10:10
- cat_on_the_tray — i keep a spare vial of bac water in the fridge purely so i never rush the maths, thats one data point 12:41
- typosquat_tay — if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way, anyway 13:19
- tga_notice — while im here swirl it. do not shake it. the foam is denatured protein and you are not getting it back, from memory 14:10
- typosquat_tay — genuine question 15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it 14:24

write the date on
20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
i use bac water even for a single-use vial because it stings less, which is not the reason it exists
while im here the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol
too dilute imo

label the vial
my vial pulled the water in on its own, is that the vacuum or did i do something
thats fine
the meniscus thing is real. read it at eye level or you are guessing by a unit either way
coming back to this why does everyone say 2ml specifically and not 1ml
quick one sanity check my maths before i pin myself with something stupid
thats 5mg/ml
i keep a spare vial of bac water in the fridge purely so i never rush the maths, thats one data point
anyone got a photo of what a properly dissolved vial looks like
weigh it first
not sterile water
if the powder is on the stopper, tap it down before you add anything. it will still dissolve either way, anyway
benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically
check your maths
read it at eye level
while im here swirl it. do not shake it. the foam is denatured protein and you are not getting it back, from memory

if the maths gives you 13.7 units, change the volume. do not try to hit 13.7, ask me again in a month
