Clomid does not cause gyno or fatty deposits. It also does not effect the amount of estrogen in your system. It just blocks the receptors estrogen attaches to. Clomid is just as effective as an anti-e as novla and even more so since it fools the pituitary into releasing LH. The problem that arises post cycle for many is they discontinue use of nolva (which blocks estrogen receptors as well) when they take thier last donse of test for example. If its sust however, they will still have a couple weeks where the test decaonate is in thier system and being released. During this time they wont have nolva in thier system to block estrogen and they will still have test aromatizing and being converted to estrogen. Basically put nolva should be used all the way up to the point when you switch to clomid and then it can be discontinued.
If using anastrozole, it will prevent the conversion of test to estrogen and a blocker like novla is not needed. Anastrozole should be used through cycle and until the clomid therapy is complete. Anastrozole has been shown to help in the release or FSH which will trigger the teste's to producse sperm, which accompanied with clomids ability to help production of LH should get you back on your feet.
