i'd go for powerfull myself. l-dopa helps with any sleep issues during PCT, and that will help you keep more if not all of your strength gains. no you cannot just cycle again... that's silly. actually its a good way to screw up your test production. you need more time off after PCT which should equal the cycle length. so if 8 week cycle, 4 week pct, then another 8 weeks off minimum, preferably 12.
