#reconstitution 2025-05-06

i was wrong about this last year: it is fine to draw cold, it just stings more going in

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

if you draw up with a bigger pin and inject with a fresh one you lose a bit more to dead space

yep 10 units

whats the smallest volume you would trust yourself to measure on a u100

check your maths

thats fine

20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy

give it 8 minutes at room temperature before you decide it has not dissolved
a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with

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

my vial pulled the water in on its own, is that the vacuum or did i do something

i use bac water even for a single-use vial because it stings less, which is not the reason it exists, your mileage will differ

sorry to jump in a slightly collapsed cake is cosmetic. a puddle in the bottom is not
one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that

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

the last few units are a real loss. i accept it rather than tilting the vial and drawing air, ill dig out the number

coming back after 18 months, has the pinned recon volume advice changed

write the date on

for the archive pick the volume so your dose is a whole number of units. thats the entire trick

30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right

Channel stats, last 30 days: 50 messages from 10 members.

thats 5mg/ml

unrelated but can i add more bac water later to a vial ive already reconstituted

one unit is 0.01ml

update from 6 months ago: switched to a single concentration and have not miscalculated since

read it at eye level

a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with
