i started an 8 week cycle of winnie tabs 2 weeks ago.it was all i could get and it was expensive so i am not able to stack it with anything.anyway, my brother is a chemist,he tested the stuff to make sure it was real before i started the cycle. I am starting to see some strength gain now but the last 3 days i have had such a bad stomache ache i stopped taking the stuff yesterday.i also just started taking milk thistle about 4 days ago.I know i should have been taking the milk thistle from the beginning of the cycle but i didnt. my stomache started to hurt the day after i started taking the milk thistle.so i was wondering if anyone has ever had any probs with milk thistle or if it is probably the winnie.i am 30 years old,5' 9",215 lbs.,been lifting for about 8 years.this my 1st cycle and i was taking 40 mg a day.has anyone ever gone to the doctor to have thier liver checked.is there such a test?,is it covered by insurance?
