alot of people use it for a liver aid. i don't think it would hurt to add it to your PCT if you have been using harsh orals. But I have not personally used it. knoiw alot of people who do use it though for a liver aid. best thing to doo is get bloodwork done post cycle and see what your liver values look like. sometimes people worry to much about their liver when taking orals. I worry myself but only bloodwork will really let you know what is going on. you cant just take milk thistle and assume everything will be OK. Liv-52 is probably a better choice.carnberry juice is always good for your organs. just depends how fucked your liver and kidney values are and you will not know that unless you get bloodwork wich is not very expensive if you have insurance.
