I have esearched alot and read lots of articles by docs,bodybuilders etc, I have talked to some well know amateurs and some aas consultants. And there is no exact answer to this question.
OPTION 1: HCG during cycle - people use around 2x250iu strating 4th or 5th week during the cycle untill the start of PCT
OPTION 2: HCG during the PCT - starting 3 week prior to PCT (1 week overlap with the cycle) with 4 shot at hight amounts 1500-5000iu until the start of the Nolva and/or Clomid
As I know so far, the answer is: USE BOTH METODS and see what works better for YOU
What u think ?
