The idea behind taking a week off and then using test ace is to shorten the time between taking hormones and PCT. It keeps your test level high the entire time leading into PCT, rather than having it slowly decline as waiting three weeks then starting PCT does. You can start PCT within a matter of days by going that route. I vastly prefer it.
Funny that you mention superdrol. My plan is, in fact to kickstart with dbol then finish with 3 weeks of superdrol. I left that part out of the cycle in my post because I know how I respond to both already.
