Highlights from this day
  • luerlok — for the archive can i add more bac water later to a vial ive already reconstituted aim the diluent at the glass wall, not at the powder. it goes in gentler 17:58
  • travel_cooler — do not add more bac water to an already reconstituted vial, you have lost track of the concentration, for what its worth 18:12
  • travel_cooler — weighing the vial before you reconstitute is the only way to catch an underfill took me a year to stop over-diluting. the measurement error at 4 units is worse than… 18:15
  • two_ml_two — it should be completely clear with no floaters. cloudy means stop 20:09

for the archive can i add more bac water later to a vial ive already reconstituted
aim the diluent at the glass wall, not at the powder. it goes in gentler

yep 10 units

do not add more bac water to an already reconstituted vial, you have lost track of the concentration, for what its worth

bac water or sterile water for something im going into weekly for 8 weeks

weighing the vial before you reconstitute is the only way to catch an underfill
took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience

coming back to this do i swirl for a specific length of time or just until its clear

nobody here should be telling you a dose. we can check your arithmetic, thats a different thing

DE

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

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

DD

gross powder mass is not net peptide. water and counterion are in that number, we shall see

DE

temperature of the diluent does not matter. how fast you push it in does

DE

ok so the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol, n of 1 obviously

too dilute imo

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

⚠️1

thats 5mg/ml

ok so update from 2 months ago: switched to a single concentration and have not miscalculated since

TM

it should be completely clear with no floaters. cloudy means stop

unrelated but label the date too. you will not remember which vial is which by week 31
