Either way, you want to be OFF of the HCG before you start PCT. If you are taking HCG, you aren't giving your body a chance to produce on it's own. Personally, I would suggest running it through the cycle, starting as early as 1 day if you like...or a few wks in. 250-500iu 2x wk, then run it like this, right up to a few days before PCT begins
