Pat,
I was replying to Bryony's comment, not criticizing you. Ignorant means uninformed or uneducated, not stupid. Your question about wanting to know if you need a T-blocker while currently using saw palmetto (which just happens to be one of the best known T-blockers) leads us to think you do not know what saw palmetto does. This makes us think you have not researched the herbs you are taking to find out what they do and how they affect your body, both good ways and bad. In Bryony's sweet way, he was subtly recommending that you might want to do some more reading around here, this is called research, to find out more of what is going on and how all these different herbs work. Most, if not all of your questions will be answered by reading previous threads and their posts on this forum. 
By the way, AbiDrew did answer your question. 
I was not intending to offend you and apologize that you took it that way.
