Info taken from the Chemical Wizardry Anabolic Steroid Database:
Clen Cycles usually last 6-12 weeks. After 2 weeks, the Beta-2 receptors down regulate and impairment of T4 to T3 conversion is impaired. Research shows that using it for two days on then two days off prevents attenuation.
Apparently, clen has a half-life in the body of 48 hours making it pretty much irrelevant when you take it. This means that two days on, two days off, conserves the number of pills you use in a cycle rather than for receptor downgrade which occurs around two weeks. The three weeks off between cycles counterbalances the receptor downgrade; the two days on, two days off reduces the side effects since on the third day of two-on two-off the concentration is highest.

Af for my personal knowledge, 2 weeks on, 3 weeks off is good.
As for a cycle, I would do one similar to the one that Little Girl did. I suggest to go with the Primo before the Winny. The probability of sides is weaker...
