I am getting 5mg Humatrope in 28 separate vials for 28 days of the month. If I understand the great info post on HGH, if 6mg = 18iu's then my 5mg =15iu's. And if 5.5 on a slin dart = 1iu, then I am getting a little LESS than 3iu's in each vial or 15iu's. Exactly 3 iu's on a slin dart would be 5.5 x 3 =16.5iu's. If I want to do 4iu's each day, then I need to get to 22 on a slin dart. IS THIS CORRECT???????
