My opinion....... Get your liver values checked........do your cycle...half way through.....get them checked again....and then again at the end.....and let us know.
Even if it IS metabolized in the liver and raises values it will not KILL you, or do any REAL permanent damage.
I'm sure drinking alcohol on a regular basis and or the use of Tylenol/Advil probably does more hepatic damage than most of the shit we pump into our bodies.
