vienna_vial — if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration, i could be wrong 22:52
bac_water_bill — i use bac water even for a single-use vial because it stings less, which is not the reason it exists 23:05
vienna_vial — pick the volume so your dose is a whole number of units. thats the entire trick 23:19

does it matter if i inject the bac water straight at the powder

my rule is one concentration for everything so i never have to think about it at 7am, we shall see

the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol

is a slightly cloudy solution ever ok or is that always a bin it

sorry to jump in my 10mg vial weighed 11.4g on the jewellery scale, is that wrong

is it worth buying a 3ml syringe for the diluent or is the insulin one fine

if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration, i could be wrong

why does everyone say 2ml specifically and not 1ml

my vial pulled the water in on its own, is that the vacuum or did i do something

the meniscus thing is real. read it at eye level or you are guessing by a unit either way, i think

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/ml

bac water

label the vial

pick the volume so your dose is a whole number of units. thats the entire trick

i write the mg/ml on the vial with a sharpie the moment i reconstitute it

20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy

the jewellery scale is a good habit but calibrate it, they drift badly
