Highlights from this day
  • quiet.hours — update on the earlier thing lyophilised powder is far more robust than people think. it is the solution that is fragile 09:40
  • chaser_chris — while im here nobody here should be telling you a dose. we can check your arithmetic, thats a different thing 10:46
  • vacuum_vic — slightly off topic but 10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use, thats just me gross powder mass is not net peptide. water and counterion are… 13:03
  • vacuum_vic — do not add more bac water to an already reconstituted vial, you have lost track of the concentration 13:12

15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it, still working it out

slightly off topic but 10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use, thats just me
gross powder mass is not net peptide. water and counterion are in that number

coming back after 7 months, has the pinned recon volume advice changed

VV

the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol

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

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

label the vial

QH

my 10mg vial weighed 11.4g on the jewellery scale, is that wrong

VV

you can absolutely just always use 2ml, and honestly most of us should
