DHT will make you lean, estrogen will make you fat. They both compete for the same receptor cells and DHT tends to slightly over power estrogen in this battle. So Proviron is an androgenic steroid in itself, and I don't recommend using a steroid to help yourself get off of steroids. I would recommend it over any other AI's or Serms during a cycle because it would not only block estrogen but it could even add a little more anabolism to the mix. Just beware of hairloss and possible prostate problems because Proviron can increase those problems. I'm already struggling with my hairline and that's the only reason that I won't use it.

Arimidex (Anastrozole), Aromasin (Exemestane), and Femara (Letrozole) will actually stop or slow down the body's conversion of testosterone into estrogen. They block or even destroy the aromatase enzymes in the body that cause testosterone to convert into estrogen. That can increase the amount of testosterone that your body produces as well as increase the amount of free testosterone in your body because almost none of the testosterone is converted into estrogen. I actually believe that using both finasteride (blocks DHT) and an AI can increase your free testosterone greatly due to almost zero conversion into estrogen or DHT, but that's just my theory.

Nolvadex and Clomid block estrogen by acting like an estrogen. So the Nolvadex or Clomid fills the receptor sites so that the estrogen cannot. Nolvadex and Clomid aren't nearly as strong as an AI because they do not stop estrogen from forming, but they are much safer on the body. With Nolv or Clo you still have estrogen in your body but it is not causing the physical effects. Estrogen is very important for your immune system and healthy cholesterol levels. Nolvadex is reported to decrease your levels of IGF-1 and that is the only reason why I don't normally recommend it. I do recommend it for longer cycles (16 weeks or more) because it is much healthier for the body than to have almost zero estrogen for several months out of the year. Because I would rather live longer with slightly smaller gains than to be a giant muscular dead guy. Clomid is great for PCT but it has some small side effects like changing your mood a little.
