Highlights from this day

birch_bloods — benzyl alcohol is what makes it bacteriostatic. it is about 0.9% typically 22:22
bea_reconstitutes — i use bac water even for a single-use vial because it stings less, which is not the reason it exists 22:25
apob_over_ldl — quick one a slightly collapsed cake is cosmetic. a puddle in the bottom is not 22:27
birch_bloods — a 3ml syringe for the diluent and a u100 for the dose is the setup most people here end up with, ymmv 22:30
vienna_vial — do you let it come to room temp before drawing or draw it cold 23:03

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

i swirl for about thirty seconds and then leave it. never had one fail to dissolve

quick one a slightly collapsed cake is cosmetic. a puddle in the bottom is not

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

thats the vacuum

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

yep 10 units

is a slightly cloudy solution ever ok or is that always a bin it

foam is bad

anyone worked out a recon volume that puts 10mg on a round unit mark

gross powder mass is not net peptide. water and counterion are in that number, from memory

the meniscus thing is real. read it at eye level or you are guessing by a unit either way

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

label the vial

read it at eye level

do you let it come to room temp before drawing or draw it cold

took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience

is it worth buying a 3ml syringe for the diluent or is the insulin one fine

how long after reconstituting before its actually dissolved

i write the mg/ml on the vial with a sharpie the moment i reconstitute it
