This is excellent information!! Thank you! I agree. My endocrinologist seemed to think the estro #s were in check. But, it seems that my body is very sensitive to hormonal levels. Small doses of test had a ridiculous anabolic affect on me (in the gym). Estro was elevated slightly but in range so my endo did nothing. So I agree with you that even though they were in range, they probably were causing my body to react in a negative way. And finally, I couldnt agree more with the comment about the extra boost from the DHT. Thanks again for the comment and response!
