no sir, nolvadex is a SERM and will only block estrogen at the receptor point (basically only helps block gyno build up, but does nothing for adverse health effects due to increased estrogen) you need and aromatase inhibitor (which actually controls the estrogen itself). I personally would go with 12.5mg of aromasin every other day and adjust from there accordingly. Good to have the Tamoxifene (nolvadex) on hand and can be used for your PCT
