It supposedly increases your testosterone level, but it also hurts the liver. I used to take it back in 2012 and when I went to get a blood test in 2014, it dramatically increased my liver enzymes (meaning I had some damage to the liver)

damn.. you ever get it checked again?
stuff like this is why i stay away from most supps. i'm taking some whey now and I still worry somewhat. I personally wouldn't try fat burners, test boosters, or those kinds of things. I especially stay away when I see tons of stuff in the ingredient label.
I've known people who just want to "try everything", I really don't get it. Some of the stuff they take, years later we find out it can be lethal, like DNP or whatever that crazy lethal fat burner is:
