Highlights from this day
  • mg_per_ml — i use bac water even for a single-use vial because it stings less, which is not the reason it exists 21:49
  • night_pin — the meniscus thing is real. read it at eye level or you are guessing by a unit either way, not advice obviously 21:52
  • two_eight_c — quick one if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space 22:09
  • two_eight_c — aim the diluent at the glass wall, not at the powder. it goes in gentler temperature of the diluent does not matter. how fast you push it in does 22:27
  • mg_per_ml — ok so the last few units are a real loss. i accept it rather than tilting the vial and drawing air 22:42

i have never once regretted using a rounder number and a slightly bigger volume

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

im getting bubbles in the barrel every single time, what am i doing wrong

how much do i lose to dead space with a 31G pin

thats fine

ok so is there any reason not to just always use 2ml

NP

is it normal for the cake to look slightly collapsed on one side
