It would be pointless for him to run PCT for only 4 weeks and then take another 4 off after that cycle. His system wouldn't be nearly recovered enough.

Doing so would put him going into a cycle with an already suppressed system, resulting in full shutdown even faster on the next cycle.

IMO, it would be best to just take off more time between the cycles, I.E. time on = time off.

Unless, he just wants to trash his system, then there isn't a problem.
