Very solid pre-workout.  I take 2 scoops before workout and sometimes add a scoop of Purple Wraath and extra creatine.  Does what it should, clean energy with no crash and good ingredient profile.  Only the original Jack3d can get 5 stars...

Cellucors' C4 is the "standard" for preworkout supplements. Enough stimulation for an advanced trainer and a tolerable level for a beginner with 150mg caffeine per serving (2 espressos....) and small amount of advantra-z (synephrine) that has a proven metabolic enhancing and fat burning effects. I always have a tub in stock and cycle it on alternating days. Its great!
