A lot of people keep asking the same boring question. Why do I recommend Aromasin over Nolvadex or Clomid over Nolvadex and so on.
First of all I don't recommend anything. Aromasin, Clomid and Nolvadex are three very different drugs and cannot be substituted one for the other.

Nolvadex is the first drug used to [U]prevent gyno[/U]. That's it. Was introduced to the world of bodybuilding back in the late 70s by Dan Duchaine.
While it's an effective anti-gyno solution it's not an Estrogen blocker or an Aromatase inhibitor. It's NOT. All it does is to bind to estrogen receptors in breast tissue and redirect estrogen to muscle tissue. Today we know that estrogen in muscle tissue blunts IGF-1 production (Note: This is the most important growth factor for gaining lean mass). We know that estrogen also reduces muscle fibre size and so on.

This makes Nolvadex inapropriate as a drug both on and off cycle. It's especially inapropriate as a PCT drug when you need to retain most of the mass acquired during the cycle.

I agree. It was clever once it was discovered but now that we have third generation Aromatase inhibitors like Arimidex, Aromasin and Letrozole that not only prevent testosterone aromatization but boost IGF-1 production as well, it's more than stupid to continue to use Nolvadex as a bodybuilding drug.

Clomid ? Clomid is also a SERM but it's so weak of a SERM that no bodybuilder uses it for this purpose. It's a great drug that boosts fertility a.k.a. sperm production off cycle. Usually compliments HCG or is used alone in milder cycles.
