got 5000 iu vials of hcg and came with 1 ml amp of im guessing bac water per 5000 iu.....my doc says mix the 5000 iu with 5 ml bac water and that would make 1000 iu per ml obviously...my question is am i better off doing it with the 1 ml it came with or 5 iu's of my own bac water???...also if i do do it with 5 ml of bac water it wont all fit in the small amp with the powder so what do i put it in when i mix it
