I chose Nolva based on feedback from many people about Clomid causing tracers and emotional problems. I don't need that shit! Based on feedback from the PCT gurus, Nolva is just as capable, it's cheap, it's readily available, and it's almost side-effect free. I've been on 40mg/day for about a week now and I don't feel any different...that is exactly the point! I've seen soooo many posts from people talking about how Clomid really screwed with their minds. ugh.
