I USE MILK THISTLE YEAR ROUND !! Regardless if I am on CYCLE or not... IT HAS NEVER DIMINISHED any GAINS that I know of from it's use while using it with the multitude of orals that I have put into my body... then again... I wouldnt know the difference would I??

Seeings how... since I used it with them and have never used them without it I dont know what kinda gains I would have achieved had I not been eating milk thistle ... so i guess it COULD inhibit gains but since I have gained just FINE and my LIVER is in PRIMO condtion... I dont see why people wouldnt just take the MILK tHistle as a PREVENTATIVE measure, ya know?
