I posted on your Nolvadex question, where that KILLED my sexdrive. I also tried this (Hyperdrol) and I would have to say no drop, but not really a boost. If I HAD to lean towards a side, I would say a slight boost, but mild if that. I'm actually on this right now, finishing up a 2 month cycle. About 3 weeks left and I'm hard as a rock and strenght gains are noticably up!
Sex drive is fine now. This product delivers as advertised.
