I've tried it before, as have some of my friends.
It claims to boost testosterone in some way or another, and libido.
I'll admit I had some fun on it. Not sure that I gained much size... but give it a shot.
It took me about 4-10 caps to feel anything.. I was taking milk thistle aswell, incase the TT is liver toxic at all.
I'd avoid alcohol while supplementing this, as I have seen one of my good bros get raged on this.
good luck
