Hi Mate, Yea I have tried it - it was one of the better tribulus based products, it worked ok. I am since using AXIS HT http://www.british-bodybuilding.co.uk/AxisHT.shtml this works better for me and has more of a spectrum of ingredients - including ZMA. I dont think you can go wrong with it.
Educate the public so bodybuilding gets the respect it deserves - we are ATHLETES!
