Well the only time i've tried clen i managed to stay on it for 3 days and the headaches were so bad at such a small dosage that i said fuck that shit. Not to mention that even though i've done complete cycles of m1t (esp. if you're not running test or at least 4ad along with it), that stuff can make you feel pretty shitty as well, so the two together are probably not the best thing you could do.
