I tried it. It's for increasing the amount of free test.
I didn't feel much from it at all, maybe a little acne.
Lots of people at BB.com love it, well they did, it isn't the big thing right now, and of course what isn't hyped now is ignored.
As much as others hate it, I honestly felt better on t-bomb II more than any natural test booster, and I've tried plenty.
