Just get off of that shit. I've been workin' out 5 days a week, for 8 years now. I do a final 3 mile cardio stint at the end of my lifting session. Most of that stuff just takes your money. You could use a strong cup of coffee (espresso ground) before your workout and it would give better results. I always have a cup of coffee, some grapefruit, a can of chicken, a glass of cranberry juice before my workout. You could also try www.anabolics.com or www.anabolicstore.com
I tried using a supplement called testdren.
