I've done a winny only cycle for 8 weeks @ 100mgs ED and only used clomid for PCT. The post that Jenetic put up was awesome and had some very valuable information in it....but like he said...there is no one size fits all methodology for PCT. First I suggest you look at the intended purpose and function of HCG, Nolva, and Clomid. If I were using a steroid that had a high affinity towards aromatization I would without a doubt incorporate Nolvadex. Nolvadex itself is intended to block the bodies estrogen receptors....by doing so estrogen is still floating around in your body....but your receptors are blocked and thus your body en essence can not detect the high levels of Estrogen. Nolva does aid in the reovery of natural testosterone production, but I feel that Clomid is far superior for that specific purpose. With a steroid like winny Nolva will help with recovery, but Clomid would be a far better and much more effective choice. With a winny only cycle for 6 weeks you wouldn't need HCG...as I feel that Clomid alone will suffice. When I do winny only cycles I stick to the standard 300mg of Clomid on day 1....100mg of Clomid on day 2 for 10 days...and then 50mg of Clomid for another 10 days...that will push your total PCT regime to 21 days which is completely effective for almost any short cycle.....a cycle consisting of a highly aromatizing steroid should have a PCT regime of clomid and nolva. Bro..i'm tellin ya..Clomid will do you just fine. Read some studies on Clomid, Nolva, and HCG and see for yourself.
