Its very simple. You have 1mg of IGF which equals 1,000 mcg. Now the easiest way I know how to do this is to add 1 ml/cc of the solution you wish to use. This is how to break it down. Every 10 on the slin pin is equal to 100 mcg. So if you want to do 60 mcg of IGF ed, then it would be 6 notches, since 1 = 10 mcg.
So here it is:
1 mg IGF = 1,000 mcg IGF
Mixed with 1 ml/cc of solution
1 unit = 10 mcg
5 units = 50 mcg
10 units = 100 mcg
100 units (1 cc) = 1,000 mcg
