tpeter and tripj,
I am still conducting a little study on myself about Arimidex, so I don't want to pass judgement yet. The initial finding is that it has pumped up my libido and erection hardness considerably. But I want to erase all other variables before I conclude something of that extent.
Also, I'm unsure whether the Arimidex is interfering with my finasteride (as mentioned above), and am worried that the original problem, that is to retain/grow hair, will not be solved.
My best advice is to see an endocrinologist and to see what they say. I recommend Dr. Frances Hayes from Yale Med. You can find her information online.
