I really have to question that. For most people it has the opposite effect. It's never really been understood. It could be some weird negative feedback loop that some peopel have. Neverthless, when the steroid gurus were saying how horny CLomid made them, thousands of guys were saying how great it was. I waas the only person to come out against it, and naturally, was attacked for it. Over a decade later, more and more guys admitted that it killed their libido and left them with weak ejaculate and it is now understood that all the studies on Clomid raising testosterone did so only temporarily. In other words...it's a useless drug.
