I personally used 2 bottles had great and very vivid dreams, increased libido that my gf hated, alpha male feeling but I wasn't aggressive and am not by nature (played football so I had an outlet at the time) and cant say I saw LBM gains from it but at my age test boosters only seem to offer so much. Best way to find out is diving on in. What else ya running with it, training routine, current goals? I do believe that it is best used in combination with others. Hope ya got one heck of a deal as the stuff is pricey AF!
