Your Right, Clomid is not to help Gyno, only Anti-E's will do that, examples:
Amimidex
Liquid Dex
Femara
These 3 will block the converstion of Test to Estrogen be about 95%- 98%
Nolvadex will block it about 100%, but can also hinder gains.
Most people will take anti-E with Aromitising Steriods such as Test, D-Ball, A bombs at about .25- .5mg per day to stop bloating. If there nips get sensitive they hit the Nolvadex usually about 20mg ED, through the rest of there cycle. These will stop the gyno.
As for Deca and Fina, gyno occurs from Progestrone and there is not a whole lot you can do. Although some people beleive Bromociptine(sp), or Vitex will help. It's just theory for right now. But there are a bunch of human guinie pigs out there work on a solution.
Clomid needs to be used after your cycle, your nuts are shut down, producing little or no test. So Clomid binds to your Estrogen sites leaving an excess of Estrogen floating around . This tells your Brain (the Hypotalimus) the get your nuts working again because your hormones are out of wack. So your brain sends out LH, and your nuts begin to wake up. With out CLomid your body just stays in flux and it takes months for it to recover. That is why BB used to loss all there gains.
Did I explain this about 70% right?
