Some say Carao extract works, I have tried it and not found that to be the case with me. Tribulus is another one that people use and I have personally felt that it has helped me in the past.
Well theres Herbal V from CVS
Tribulis , Horney goat weed(didn't do crap 4 me),Carao extract,then moving on up to the bigger leagues theres Test,Viagria,Cialias just to name a few!
First of all go to the doc and check your hormone levels....you have to find out first if there are something wrong with your test production or you just are stressed, etc..After that you have to lear how to treat your sex drive..
