well common math would tell you that 1ml=200mcg.... .5ml=100mcg... .25ml=50mcg 1ml=100cc's so im assuming your insulin pin is a 50cc so take about 25cc's alittle less if desired and shoot it in your mouth, the only thing to be careful about is if your hands are shaky while drawing it out of the bottle watch out that you dont accidently tip it over, i have had this problem almost everyday of almost spilling, i take 2 doses a day and i have heard not take it after 4pm, so i follow that as a guideline, 8am 50cc and then 3-4pm 50cc also dont take it before you workout because sometimes you shake and feel weird, just take it after you workout and you should be cut in no time, also remember alot of it is in the diet. Good luck bro
