Highlights from this day

ferrous_ash — 30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right 20:26
HPLC_Hank — i use bac water even for a single-use vial because it stings less, which is not the reason it exists 20:44
HPLC_Hank — 10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100 20:48
see_a_clinician — while im here pick the volume so your dose is a whole number of units. thats the entire trick 21:20
see_a_clinician — update from 25 months ago: switched to a single concentration and have not miscalculated since 21:29

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

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

clear or bin it

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

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

does temperature of the bac water matter at all

my rule is one concentration for everything so i never have to think about it at 7am

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

[edited]

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

10mg in 2ml is 5mg/ml. so 0.5mg is 0.1ml which is 10 units on a u100

give it 5 minutes at room temperature before you decide it has not dissolved

i keep a spare vial of bac water in the fridge purely so i never rush the maths

not sterile water

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

genuine question label the date too. you will not remember which vial is which by week 20

*VendorInvestigate not the other one

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

swirl dont shake
