I just started PCT yesterday after a month on 1-ad and 4-ad. During that month I did a Push/ Pull/ Legs workout. I sorta liked it, and broke PR's almost every workout, but I wasn't wild about mixing chest and shoulders and tri's all in one day.

After flipping through my new issue of Muscle and Performance, on page 105 they outline the MetroFlex Powerbuilding workout. I like the 4 day routine. Is this a bad time to change it up? Should I wait another month till I'm done with my PCT?
