Looking for a new pre work out supplement

[kelleymmm1]

I have taken no explode for a while and protien shakes for after workout. I want something more than no explode I was thinking about muscle techs vapor. What could I take to see results while at the same time helping with endurance. Im in the army and have to take PT test 2mile run push ups and sit ups. So I guess I want to build lean muscle. At the same time I like to lift wieghts. I also see alot of people talking about cycles I guess with a mass stack of some kind. A while back I tried 3 AD but they dont sell it at the gnc anymore. Is there anyone with a little feed back on what I should try? thanks.
