Its over the counter like a vitamin man, its milkthistle... you know the weeds in the grass (if you rip the leaves off a milky substance comes out... the pills are a form of that, an d the definitely heal the liver more than not taking them... most body builders who take steriods (which damages the liver when taken orally) take about 1000mg a day. Id suggest taking about 1500 for your situation.. its not going to damage you in any way if you take too much.. I can go and pick it up at a GNC here in canada, I dont know what the equivalent would be in the states, or if you have a GNC there, but its well worth it and its relatively cheap..
