I have 18 IU in a vial and I am using 0.2mL which comes out to 3.7 IU per shot, Mon-Fri. Actually am feeling a little better, but really feel I have f-ed up this cyc. Started Tue night, it is only Thurs and couldn't make it to the gym today. All I have had to eat is 1 bowl oats and 1 prot shake...Hope tommorrow is better....
