I'm seeing a lot of posts lately saying that people are reporting low test levels and messed up liver values partway through a cycle. I have also seen in the past people saying "liver toxicity is overrated. People stress it way too much, it's not THAT big of a problem". Let this be a lesson for all of us, it cannot be stressed enough that methylated compounds are very stressing on the liver, and proper precautions need to be taken. And even when proper precautions are taken, problems can still easily arise. Nolva does not mean you will be gyno free, milk thistle and NAC does not mean you will not have elevated liver values, hawthorn berry does not mean your blood pressure will not rise. Precautions need to be taken, and it needs to be stressed as though it is a life and death matter, because in some cases, it may very well be.
