you can absolutely just always use 2ml, and honestly most of us should
#reconstitution 2025-03-02
it should be completely clear with no floaters. cloudy means stop
write the date on
anyone got a photo of what a properly dissolved vial looks like
yep 10 units
bac water or sterile water for something im going into weekly for 7 weeks
my vial pulled the water in on its own, is that the vacuum or did i do something
took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience
coming back to this is there any reason not to just always use 2ml
why does everyone say 2ml specifically and not 1ml
what do you do with the last 8 units when you cant draw them cleanly
check your maths
thats 5mg/ml
is it worth buying a 3ml syringe for the diluent or is the insulin one fine
update on the earlier thing dead space in a standard insulin syringe hub is small but it is not nothing over a month, thats just me
if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration, we shall see
weigh it first
nope, redo it
how do you all measure a half unit, or do you just not
not sterile water
whats the smallest volume you would trust yourself to measure on a u100
label the date too. you will not remember which vial is which by week 10
thats fine
if i add 5ml to a 10mg vial what concentration am i actually at
do you draw up with the same pin you inject with
if the maths gives you 13.7 units, change the volume. do not try to hit 13.7
aim the diluent at the glass wall, not at the powder. it goes in gentler
gross powder mass is not net peptide. water and counterion are in that number, i could be wrong
is the meniscus reading actually a real source of error or am i overthinking
anyone worked out a recon volume that puts 1mg on a round unit mark
follow up if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space
bac water
swirl dont shake
pick the volume so your dose is a whole number of units. thats the entire trick
how much do i lose to dead space with a 31G pin
the last few units are a real loss. i accept it rather than tilting the vial and drawing air
dead space
5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose
