My favorite was the old formula for Super Charge Xtreme N.O. Now they changed the formula and simply call it Super Charge Extreme (without the N.O.).
I found some at a GNC so I stocked up on it after it was replaced with the newer version online. I also think Jack3d is one of the most overrated products on the market.
Yep that is the only shit I was taking at the time that would have caused liver issues, my doc is actually pretty smart on gear and stuff of that nature.
