#reconstitution 2025-12-11
Thursday24 messages8 participantstimes are UTC
Highlights from this day
- dublin_dose — follow up 20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy, thats just me 22:50
- escalation_anxiety — a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with 22:54
- VialBot — Verification log updated: QST — evidence added, status unchanged. 23:36
how long after reconstituting before its actually dissolved
10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100
ok so it should be completely clear with no floaters. cloudy means stop
i was wrong about this last year: it is fine to draw cold, it just stings more going in, thats one data point
my 10mg vial weighed 11.4g on the jewellery scale, is that wrong

check your maths
follow up 20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy, thats just me
a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with
U-100 syringe: 1 unit = 0.01 ml
10u = 0.10 ml
25u = 0.25 ml
50u = 0.50 ml
100u = 1.00 ml
mg drawn = ml drawn x mg/ml✅11👍12
is there any reason not to just always use 2ml
write the date on
why does everyone say 2ml specifically and not 1ml
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing
gross powder mass is not net peptide. water and counterion are in that number, thats just me
is a slightly cloudy solution ever ok or is that always a bin it
i keep a spare vial of bac water in the fridge purely so i never rush the maths, still working it out
i use bac water even for a single-use vial because it stings less, which is not the reason it exists

follow up the jewellery scale is a good habit but calibrate it, they drift badly

lyophilised powder is far more robust than people think. it is the solution that is fragile
right so a slightly collapsed cake is cosmetic. a puddle in the bottom is not
does benzyl alcohol matter if im finishing the vial in one go
