This article is by Bill Lewellyn the author of Anabolics 2000 and Anabolics 2002. The assertion is similar to one that caused a lot of debate here (and on BB.com) before.

Interestingly, Bill quotes several studies that seem to support his assertion.

I can't say that I am sold on the idea, but the economic implications intruige me:

Nolvadex, used for 10 days at a dosage of 20mg daily, increased serum testosterone levels to 142% of baseline, which was on par with the effect of 150mg of Clomid daily for the same duration (the testosterone increase was slightly, but not significantly, better for Clomid)

One Nolvadex 20mg is a hell of a lot cheaper than three Clomid 50mg!
