I'm nearing the end of a two can Test cycle (Test+Stak). After that, I will be cycling off and running a can of MStak. I did this before a few years back with good results. After completing the two cans of test+stak and then doing the 3 weeks of Mstak, can I pick back up with another cycle of Test+Stak? Should I go a little while completely off everything? How often do you suggest a total break from it all?
