Highlights from this day
- ghent_gradient — do you draw up with the same pin you inject with 07:07
- hair_month_four — the meniscus thing is real. read it at eye level or you are guessing by a unit either way 07:18
- patent_2026 — 15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it my rule is one concentration for everything so i never have to think about it at 7am 08:14
- u100_pat — i was wrong about this last year: it is fine to draw cold, it just stings more going in 08:28
- reship_rita — nobody here should be telling you a dose. we can check your arithmetic, thats a different thing 08:38
weighing the vial before you reconstitute is the only way to catch an underfill

20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy, ymmv
swirl dont shake

thats the vacuum
do you draw up with the same pin you inject with
U-100 syringe: 1 unit = 0.01 ml
10u = 0.10 ml
25u = 0.25 ml
50u = 0.50 ml
100u = 1.00 ml
mg drawn = ml drawn x mg/mlclear or bin it
read it at eye level

does benzyl alcohol matter if im finishing the vial in one go
anyone else find the 20mg vials harder to get fully dissolved than the small ones
you can absolutely just always use 2ml, and honestly most of us should
the meniscus thing is real. read it at eye level or you are guessing by a unit either way
sanity check my maths before i pin myself with something stupid
do you let it come to room temp before drawing or draw it cold
thats fine

the jewellery scale is a good habit but calibrate it, they drift badly
round numbers
[edited]thats 5mg/ml
[edited]yep 10 units
weigh it first
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing
i keep a spare vial of bac water in the fridge purely so i never rush the maths
