So I've been training for several years, and competing for that time as well.
Cycled the E.C.A stack, and all the old school fat burners out there.
So Preworkouts? Favorites, why do you think others are better, and what do you use?

Here is my prework out that seems to be working

1 1/2scoop Muscle Prime
50g Vitargo (or Carbion/Glycofuse) pending on workout day
10g Glutamine
1 tablespoon of L-Carnitine
3 scoops of ON Energy

2 Polquin Mental Focus
1500mg Ginseng
1000mg Vit C
1600mg Poliquin Beta Alnine

1 hour pre workout

Thanks for the suggestions
