I've tested quite a few myself and so far I'm liking DAA and Endosurge. The Endosurge covers Macuna and Nettle Root and gives a really nice libido boost. I tried Erase for estrogen control but, even at low doses (1 pill 25mg per day), it bothered my joints too much. Nutraplanet has an excellent deal on the Endosurge/Erase combo when their in stock. Have never tried Formadrol or Betaine so can't comment on them but am interested in topical Formasurge.
Not a fan of Trib products.
