#reconstitution 2026-02-20

too dilute imo

i have never once regretted using a rounder number and a slightly bigger volume, n of 1 obviously

i use bac water even for a single-use vial because it stings less, which is not the reason it exists

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

if the maths gives you 13.7 units, change the volume. do not try to hit 13.7

one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that

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

coming back after 17 months, has the pinned recon volume advice changed

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

a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with

took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience

weighing the vial before you reconstitute is the only way to catch an underfill

gross powder mass is not net peptide. water and counterion are in that number

not sterile water

if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space, from memory

benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically

read it at eye level

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

the last few units are a real loss. i accept it rather than tilting the vial and drawing air, your mileage will differ

10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use, from memory

aim the diluent at the glass wall, not at the powder. it goes in gentler
