This supplement has bulbine natalensis, which canboost your natural testosterone production. What I like about it, isthat bulbine will also block estrogen. Also, there is the fadogiaagrestis in it, which will also help with libido and sexualperformance. This supplement has a bunch of many other usefulingredients, and it really works. Check out the Phytoserms-347 byN2BM, I think this is the one your doctor was talking about.
