I been reading on the boards that you should match the time on (cycle) to the time off (recovery), meaning if you're on a cycle for 12 week you should take off 12 weeks for recovery. I know guys that only take 5-8 weeks off for recovery and their doing 10-14 weeks cycles. Is there any evidence proving that the body recovers in just a few weeks? or matching the time on is just to be safe.
