#reconstitution 2025-07-20

Sunday23 messages5 participantstimes are UTC
Highlights from this day
  • appetite_back — how long after reconstituting before its actually dissolved 10:21
  • tarpit_tam — give it 2 minutes at room temperature before you decide it has not dissolved 10:27
  • tarpit_tam — benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically 11:26
  • septum_sal — i use bac water even for a single-use vial because it stings less, which is not the reason it exists 11:54

while im here 5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose

anyone got a photo of what a properly dissolved vial looks like

SA

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

not sterile water

bac water

genuine question how do you all measure a half unit, or do you just not
i keep a spare vial of bac water in the fridge purely so i never rush the maths

how long after reconstituting before its actually dissolved

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

too dilute imo

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

AB

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

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

thats the vacuum

weigh it first

a slightly collapsed cake is cosmetic. a puddle in the bottom is not

SA

anyone else find the 10mg vials harder to get fully dissolved than the small ones
