update from 19 months ago: switched to a single concentration and have not miscalculated since

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

does benzyl alcohol matter if im finishing the vial in one go

right so the powder is stuck to the stopper, do i care

Testing queue: 3 submissions open, 21 awaiting dispatch.

ok so 5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose

update on the earlier thing swirl it. do not shake it. the foam is denatured protein and you are not getting it back

i have never once regretted using a rounder number and a slightly bigger volume

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

anyone else find the 40mg vials harder to get fully dissolved than the small ones

temperature of the diluent does not matter. how fast you push it in does
the jewellery scale is a good habit but calibrate it, they drift badly

read it at eye level

nobody here should be telling you a dose. we can check your arithmetic, thats a different thing

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

how do you all measure a half unit, or do you just not

is the meniscus reading actually a real source of error or am i overthinking

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

the last few units are a real loss. i accept it rather than tilting the vial and drawing air

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