That is a good link. If you need a supplement to help you wake up (not to be mistaken for faux intensity), what have you tried already? Different people react in different ways to supps. Ephedrine doesn't really bost my energy, nor does clen. However, a cup of coffee will do it to me every time.
Are you getting enough carbs in before your workout? Try eating a high-carb meal 1.5 hours before your workout. I also down plenty of simple sugars before my workout as well. If I need a little kick, I'll take 200mg of caffeine.
