I do a cut/bulk every cycle, so I think its a great idea. I think 22 weeks is a little long though. My cycles generally don't exceed 16 weeks. Its best to capitalize on pushing calories up to about 8 weeks for muscle gain. After that, myostatin levels are so high, that switching to more of a cut makes sense for the remainder of the cycle since further muscle gain is hindered to next to nothing. Using the rest of the cycle on high androgens to maintain muscle mass makes perfect sense to me. I always end a cycle weighing more with less body fat, and it has worked well
