for the prostate, zinc and saw palmetto. People with bph are usually very low in zinc. You also lose zinc when you ejaculate, so if your on cycle and walking with wood, shooting 2-3 times a day, 50-100 mg zinc a day might help. For liver i use liv 52 and milk thistle. I always have my liver functions tested throughout a cycle and have never had any problems. I stay on those supps year round.
