For a Havoc cycle the Nolva only really needs to be run at 20/20/10/10. 120mg of Nolva is way to much Nolva. I would also run some liver support while on the Nolva as it is also somewhat toxic to the liver.
the side affects of damage to the liver arent something you can really tend to see right away. Back in arnie's day guys ran d-bol for up to 14 weeks and I'm sure they didnt think they were getting liver damage either. On the same hand I dont feel havoc is that harsh that you need to go crazy with all this support stuff. Milk Thistle actually interferes with the absorbtion of the prohoromone, there were studies done on this, so its best to just take milk thistle before or after the cycle just to help your liver recover better. Where you should get worried about your liver is when your taking havoc and then going out slamming down beer after beer, then your gonna have some serious problems.
I could care less if you take liver support or not it is your body. Havoc is a 17a methylated steriod period and should be treated as such. To say you do not need any supports is foolish. Any methyl can and will be harsh on the liver and many people have blood pressure problem on it.
