Highlights from this day
  • sulphur_burp — gross powder mass is not net peptide. water and counterion are in that number, for what its worth 14:43
  • mhra_unlicensed — ok so lyophilised powder is far more robust than people think. it is the solution that is fragile 18:01
  • swirl_not_shake — sorry to jump in sanity check my maths before i pin myself with something stupid give it 8 minutes at room temperature before you decide it has not dissolved 18:08

update on the earlier thing 10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use

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

RR

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