I have read a lot of threads on here where people are posting their cycles along with their PCT for critique. I guess there is one thing that still confuses me and I have yet to see it brought up recently. I guess i really don't understand the what the point is of running both Nolvadex and Clomid during PCT. As I understand 20 mg of Nolvadex is equivalent to 150mg of Clomid. They are both a SERM and both are said to have a natural test increase of 150% over baseline. I have normally run an AI during my cycle and used Nolvadex alone in the past and had no issues with natural test levels returning or estrogen rebound. Anyone care to educate me a little further as to what the purpose of running both would be?
