The only HCG i can find is in amps and each amp is 2000iu and comes with 3 amps.......If i run HCG for 2-3 weeks b4 PCT at 250iu a day.....how will i determine what 250iu is? i'm also getting told One shot every 5-6 days. Starting off with one shot of 3000 IU somewhere in the last week of your stack, then another 3000 5 days later, then drop to 1500 5 days later and a last shot of 1500 6 days after that, could i do either one? I have never done HCG b4 so i also have one more question....it says that it does not come with water and to mix it with any kind of distilled water, how would i do that and what is iu in cc's?
