Highlights from this day
- step_one_sian — dead space in a standard insulin syringe hub is small but it is not nothing over a month 13:24
- split_shipment — right so is it normal for the cake to look slightly collapsed on one side 13:25
- chlorhex — if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space 14:02
nope, redo it

the powder is stuck to the stopper, do i care
sorry to jump in anyone worked out a recon volume that puts 1.7mg on a round unit mark
do you let it come to room temp before drawing or draw it cold
do you draw up with the same pin you inject with
one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that, not advice obviously
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing
one unit is 0.01ml
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
read it at eye level
gross powder mass is not net peptide. water and counterion are in that number
20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy

how long after reconstituting before its actually dissolved
the last few units are a real loss. i accept it rather than tilting the vial and drawing air
it should be completely clear with no floaters. cloudy means stop
yep 10 units
if i add 1ml to a 2mg vial what concentration am i actually at
lyophilised powder is far more robust than people think. it is the solution that is fragile
[edited]swirl it. do not shake it. the foam is denatured protein and you are not getting it back
label the vial
im getting bubbles in the barrel every single time, what am i doing wrong
aim the diluent at the glass wall, not at the powder. it goes in gentler
pick the volume so your dose is a whole number of units. thats the entire trick
write the date on
label the date too. you will not remember which vial is which by week 32
a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with
follow up it foamed. is it ruined
too dilute imo
