Anything that gets your heart rate up is not good to take prior to exercise. But, young and dumb have been doing it for generations and it won't stop with you. Haven't you heard of all these kids, your age, dropping dead on basketball courts, football fields, etc!

You may survive it, most likely will! If you already have a minor mental prob.; leave it alone! There will never be enough studies to say what it does to your brain and it already needs a bit of help!

If I could cut & paste: Veggii says it best; "Sounds like you made up your mind. You'll do as you want!" 'Are you still here?"

You have every explanation in the world above, not to do the latest craze! Coca-cola with aspirin has a new high and this is it for today's generation?! today's athletics, have taken that crap and find out years later, It Was Bad for Me! Like boxers who kill their family's. Guess, it would be a 'stepping stone' drug for you to get something else if it doesn't do what you want!

Apparently, you want to buff your body for looks. That is superficial and you sound determined! I admire exercise nuts, use to be one.

Let us know if you have a stroke, if your heart rate gets too high. Natural exercise will increase your heart rate, which is the purpose of exercise. You don't need it with the above proper advice!:thumbsup:

So, drink the stuff, take your pulse, skip the exercise and toke! You want to take care of and not abuse your body with supplements. Take care of yourself, a bit better! :hippy:
