My favorite pre-workout rush stack is 50mg ephedrine, 400mg caffeine, and 3-5 Thailand dianabol. Not to get ahead of myself but the amino acid L-tyrosine will work by its own mechanism to stimualte neural firing and immediate strength gain (for this you will need at least 2, not more than 4 grams). Make sure you have an empty stomach, add some carbonation (like a Red Bull), and the whole mix gets into your system much faster. Yeah, I dreamed this once, I umm...never actually did it. Remember too, I am fairly young and although I may be a physique/physiology,drug/bodybuilding obsessed maniac - have no cardiovascular risk factors (high blood pressure, cholesterol, clogged arteries, etc).
