anyone worked out a recon volume that puts 1mg on a round unit mark

Highlights from this day
- vial_ledger — i write the mg/ml on the vial with a sharpie the moment i reconstitute it 21:11
- deadspace — my 10mg vial weighed 11.4g on the jewellery scale, is that wrong 21:24
- cagri_curious — im getting bubbles in the barrel every single time, what am i doing wrong 22:03
- fridge_thermo — give it 4 minutes at room temperature before you decide it has not dissolved 22:32
check your maths
took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience
write the date on

foam is bad
pick the volume so your dose is a whole number of units. thats the entire trick
do not add more bac water to an already reconstituted vial, you have lost track of the concentration, not advice obviously

too dilute imo
⚠️1💀1😂1
thats 5mg/ml
i use bac water even for a single-use vial because it stings less, which is not the reason it exists, i think
quick one nobody here should be telling you a dose. we can check your arithmetic, thats a different thing
20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
*mg/ml, obviously
while im here the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol
im getting bubbles in the barrel every single time, what am i doing wrong

does temperature of the bac water matter at all
label the date too. you will not remember which vial is which by week 26
dead space in a standard insulin syringe hub is small but it is not nothing over a month
Reminder set. I will post here in 9 days.
ok so lyophilised powder is far more robust than people think. it is the solution that is fragile

30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right, for what its worth
how do you all measure a half unit, or do you just not
read it at eye level
give it 4 minutes at room temperature before you decide it has not dissolved

yep 10 units
