dead space in a standard insulin syringe hub is small but it is not nothing over a month
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing

foam is bad
does it matter if i inject the bac water straight at the powder
bac water
weigh it first
the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol, we shall see
sorry to jump in one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that
sorry to jump in aim the diluent at the glass wall, not at the powder. it goes in gentler
anyone got a photo of what a properly dissolved vial looks like
the jewellery scale is a good habit but calibrate it, they drift badly
if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
the meniscus thing is real. read it at eye level or you are guessing by a unit either way
slightly off topic but my rule is one concentration for everything so i never have to think about it at 7am
it should be completely clear with no floaters. cloudy means stop
a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with, thats just me
thats fine
U-100 syringe: 1 unit = 0.01 ml
10u = 0.10 ml
25u = 0.25 ml
50u = 0.50 ml
100u = 1.00 ml

i have never once regretted using a rounder number and a slightly bigger volume
took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience
not sterile water
pick the volume so your dose is a whole number of units. thats the entire trick
i swirl for about thirty seconds and then leave it. never had one fail to dissolve
ok so if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space, ymmv
too dilute imo
label the vial
thats 5mg/ml
can i add more bac water later to a vial ive already reconstituted
update from 3 months ago: switched to a single concentration and have not miscalculated since, ask me again in a month
[edited]i use bac water even for a single-use vial because it stings less, which is not the reason it exists
swirl dont shake
read it at eye level
genuine question label the date too. you will not remember which vial is which by week 8
update on the earlier thing i write the mg/ml on the vial with a sharpie the moment i reconstitute it, your mileage will differ
you can absolutely just always use 2ml, and honestly most of us should, for what its worth
clear or bin it
it foamed. is it ruined
im getting bubbles in the barrel every single time, what am i doing wrong
write the date on
slightly off topic but 20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
check your maths
is a slightly cloudy solution ever ok or is that always a bin it
coming back after 20 months, has the pinned recon volume advice changed
weighing the vial before you reconstitute is the only way to catch an underfill
