30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right

Highlights from this day
- auckland_aliquot — follow up how long after reconstituting before its actually dissolved 22:03
- slow.taper — slightly off topic but i use bac water even for a single-use vial because it stings less, which is not the reason it exists 22:05
- fridge_thermo — 10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use, take that with a pinch of salt 22:21
- glasgow_vial — dead space in a standard insulin syringe hub is small but it is not nothing over a month 23:18
5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose
Assay note: MKM lot G-0641 reported at 99% of label content.
too dilute imo
label the date too. you will not remember which vial is which by week 29
follow up how long after reconstituting before its actually dissolved

i was wrong about this last year: it is fine to draw cold, it just stings more going in

slightly off topic but im getting bubbles in the barrel every single time, what am i doing wrong
[edited]if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space, i could be wrong
anyone got a photo of what a properly dissolved vial looks like
aim the diluent at the glass wall, not at the powder. it goes in gentler
the meniscus thing is real. read it at eye level or you are guessing by a unit either way
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing
bac water
10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use, take that with a pinch of salt

dead space
[edited]is there any reason not to just always use 2ml
anyone else find the 10mg vials harder to get fully dissolved than the small ones

slightly off topic but the jewellery scale is a good habit but calibrate it, they drift badly
swirl dont shake
coming back to this the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol
label the vial
check your maths
update from 19 months ago: switched to a single concentration and have not miscalculated since
thats 5mg/ml
does it matter if i inject the bac water straight at the powder
you can absolutely just always use 2ml, and honestly most of us should
i write the mg/ml on the vial with a sharpie the moment i reconstitute it

i swirl for about thirty seconds and then leave it. never had one fail to dissolve
not sterile water
right so give it 9 minutes at room temperature before you decide it has not dissolved, thats one data point
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing, someone check my working
clear or bin it
thats the vacuum
nope, redo it
round numbers
weighing the vial before you reconstitute is the only way to catch an underfill
temperature of the diluent does not matter. how fast you push it in does

yep 10 units
do you draw up with the same pin you inject with
write the date on

do not add more bac water to an already reconstituted vial, you have lost track of the concentration
what do you do with the last 50 units when you cant draw them cleanly
whats the smallest volume you would trust yourself to measure on a u100
pick the volume so your dose is a whole number of units. thats the entire trick
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, i could be wrong
i have never once regretted using a rounder number and a slightly bigger volume
🙏1📉8
thats fine
foam is bad

read it at eye level
i keep a spare vial of bac water in the fridge purely so i never rush the maths

my 10mg vial weighed 11.4g on the jewellery scale, is that wrong
does benzyl alcohol matter if im finishing the vial in one go
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
swirl it. do not shake it. the foam is denatured protein and you are not getting it back
