To make a long story short a friend of mine took some tamoxifen and then went to play in a competitive soccer match and told me that he was running super fast but he was unable to breathe heavily he could only breathe normally and then felt like he couldn't breathe at all... he says he did some research and he feels that the tamoxifen cause this or the Arimidex or whichever one it was I believe it was actually Arimidex. Is this possible?
