Please spend allot more time on here researching exactly what is post cycle therapy and what you do to your body when you run a "cycle".

For general liver, i would look at AX perfect cycle liver support, a seperate high dose of Milk thisle and AI's Cycle support.
Frankly, if you insist on using this Novedex XT for your PCT and nothing else, I would try to budget liver replacment proceedure once your done with your M1t.
If you really want to do this safely and do not want to run that much risk, you should be looking at other orals less harsh or a non hormonal stack. There is allot of good stuff out there that produce good results with low or less risk. But since you have already commenced the m1t dosage, I would purchase all thats been mentioned immeditly. You only have one liver and PCT is something that needs correctly and not half ass'ed.
