i got my sample in the mail yesterday, and took it today before my back workout. i gotta say, this stuff was REALLY strong to me. pumps were awesome, energy was through the roof, and i was burning hot and sweating like a pig (i normally barely sweat at all). i personally would use the product, but probably at half dosage, because it made me a little too jittery and seemed a bit too potent for me (i weigh 188lbs).
overall however, thumbs up from me. :thumbsup:
just curious, what is the caffeine content per serving? it felt pretty high. i skipped my coffee today, but i'm used to drinking 3-4 cups of coffee during the day and i NEVER get this much of an energy rush.
