Did 4 weeks of OT at 60mg a day and var at 30mg for 4 weeks, started feeling like crap so went and liver enzymes were about quadruple what they should have been in both categories, but I was an idiot and didn't take any liver protectants of any kind. Had them checked four weeks later after taking milk thistle and ALA and both numbers were great....lesson learned for me. Had great gains in the 10 pound range and kept maybe half, but I've been dieting as well.
