I agree with the above suggestions. Nolva is a SERM, which means that the compound attaches to estrogen receptors in areas of the body. With the SERM attached to the receptor, estrogen can not attach to those receptors and cause growth and all the other things estrogen does to the body. However it does not affect the amount of estrogen circulating in the body, so estrogen still effects those areas which do not have estrogen receptors. Water bloat is an example of an area or process in which a SERM has no affect.
In order to lower your overall estrogen levels you must use an aromatase inhibitor or an AI, such as aromasin or arimidex. These compounds block the enzyme called aromatase which is responsible for converting androgens into estrogen. Using an AI results in a reduction of the overall estrogen level in the body, thereby reducing the negative effects of estrogen for bodybuilders like gyo and water bloat. Its important to ensure that you get your AI dosage level correct for optimal effect as too little estrogen will also have negative consequences like mood changes, low libido, and muscle growth reduction. If using an AI start at 1/4 of the tablet dose and work your way up until you find your optimal level.
