i just got my pins in today for hgh. its a 29g 1cc/ 100 unit needle. so when i try to figure out what 2ius are is where i get screwed up. from what i have read ius are measured differently according to their strengths and types. ex: was 100iu of vitaminc C is not the same as 100iu of vitamin A. WTF !! how many units is equal to 1iu ???
one site said
1 ml = 18 iu i think this one is correct
1ml= 3.3 ius
