I just posted this in another thread.
Not everyone takes the same precautions on how much time to spend "off," but I guess my personal opinion is to spend twice as much time off as on in general.
This really isn't a matter of right or wrong, just how comfortable one feels in their particular protocol being safe. I personally don't compete, so I have no reason to push the envelope as far as increasing my total time juicing relative to the amount of time off of gear.
