Query: works but at what cost

I used half the recomended dosage for a month, had great workouts and then had a routine physical amd guess what. My Alt and Ast liver enzymes were over double what they should be. I do drink socially, however 2 months after I discontinued use of no xplode and kept everything else consistant my liver enzymes dropped back to the normal range. This stuff is very dangerous and should be removed from the market.
