Orals are only harsh in that aspect when methylated. Certainly with TR3ST you still have to worry about lipids and BP but those are things you have to worry about on injection cycles too which are often run 14 weeks and often up into the 20 week ranges. Many stay on all year long cruising and blasting with no health issues they just keep an eye on the blood work. If he has been using TUDCA during this run he should not even really have any liver damage to speak of from the low doses of EPI he has been running, taking 4 weeks off the methyls his liver values will be back in normal levels anyway. Believe it or not the level that these designers actually effect the liver when run with proper support and adequate water is very minimal. Especially the ones currently on the market. Not like anything out now is anywhere near as toxic as superdrol was.Bottom line the layout he has it would not be a problem for him at all assuming he does not have a form of liver disease already. Obviously if his liver is already in trouble then that is completely different. For a healthy liver recovery from the 4 week EPI cycle should be no problem in time to pick up another methy in 4 weeks. It is pretty common practice now to run methyls for 8 weeks concurrently. Since the introduction of TUDCA there has been a big change in safety for running them longer. Typically toxicity comes from the bile ducts becoming blocked so the toxins can not be released so they are held in the liver causing inflammation and scarring. TUDCA causes the bile ducts to continue to flow so the toxins are no longer just sitting there in the liver compounding the damage. So now there is far less initial damage and recovery is easy peasy. As an example I ran a 16 weeker recently, the first 4 weeks was 50mg dmz, 50mg halo, and 40mg LMG per day, then I went to EPI @90 a day and Hex at 135 a day for another 5 weeks and then started Tren-Devastation which is non-methylated. I went and had bloodwork done 3 weeks after I finished the EPI so a total of 9 weeks on high dosed methyls and 3 weeks later I was in the normal range for all my liver values. Consider that I tend to get a lot of sides this is pretty impressive proof of the livers ability to recover quickly.
