yes sir. u may want to go with something stronger. tylers liver detox u can get from the AF store on this site. it is prescription stuff u can get it there though, some formality. otherwise get some liver cleanse from gnc. it has milk thistle and many other roots and herbs in it that help clean out the liver. so its milk thistle and more. your fine though. thats a little over a month. man i did 6 months of winny cause i thought it was harmless back when i knew jack shit and didn't come on her. i copied my best friend who did winny straght for 2 years. no liver damage for him or me. i don't care a lot fo bros don't believe but i begged this kid to get off the winny once i learned what it would do to the liver, he stayed on for 2 years not listening. so with 40 days your fine, but yes take percaution anyway. everyones liver is different
