gross powder mass is not net peptide. water and counterion are in that number
#reconstitution 2026-03-17
how long after reconstituting before its actually dissolved
10mg vial
+ 1.0ml -> 10.0 mg/ml 0.5mg = 5u 1mg = 10u
+ 2.0ml -> 5.0 mg/ml 0.5mg = 10u 1mg = 20u
+ 2.5ml -> 4.0 mg/ml 0.5mg = 12.5u (dont)
+ 5.0ml -> 2.0 mg/ml 0.5mg = 25u 1mg = 50uthats the vacuum
nope, redo it
my 10mg vial weighed 11.4g on the jewellery scale, is that wrong
ok so if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
write the date on
i use bac water even for a single-use vial because it stings less, which is not the reason it exists
read it at eye level
is it normal for the cake to look slightly collapsed on one side
check your maths
one unit is 0.01ml
swirl dont shake
the powder is stuck to the stopper, do i care

i have never once regretted using a rounder number and a slightly bigger volume
the last few units are a real loss. i accept it rather than tilting the vial and drawing air, ill dig out the number
one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that, take that with a pinch of salt
i swirl for about thirty seconds and then leave it. never had one fail to dissolve
round numbers
anyone worked out a recon volume that puts 10mg on a round unit mark
do not add more bac water to an already reconstituted vial, you have lost track of the concentration
i was wrong about this last year: it is fine to draw cold, it just stings more going in
unrelated but 10mg in 1ml is 10mg/ml, so 2.5mg is 25 units. thats the one i use
if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
anyone got a photo of what a properly dissolved vial looks like
bac water
if i add 2ml to a 2mg vial what concentration am i actually at
