I did that my first cycle for PCT and didn't see any visable effect compared to the rest of my cycles to warrant doing it again. My diet, protien intake and training regimine was spot on for my first 2 cycles and again like I said, nothing extra in kept gains to warrant using both. I have since found that proviron and nolvadex does wonders for me as where clomid isn't anything I will buy again as long as I can get the other two compounds. Just my two cents on this issue. Then again my cycles where fairly low doses for shorter periods of time (10 - 12 weeks) Maybe clomid exhibits better effects for longer cycles. I really don't know.
