Hey you might wanna read this article if you haven't already.. it'll show why exactly the 2week on/off method is a poor choice while using clen.. just some food for thought
its found here..

So Let´s re-examine that first point I made: Clen vs. clen+ exercise produce roughly the same results for the first 2 weeks! This tells me that the 2 weeks on and 2 weeks off schedule for clen dosing is far from optimal, and if you want the quasi-anabolic effect from the clen, it´ll take more than 2weeks on (6 weeks apparently). In addition, since clen alone is similar to clen+ exercise for those first 2 weeks...why would you ever use a 2on/2off protocol? Keep in mind that animal responses to beta-agonist/antagonists differ a bit from ours but I´m sure that you get the idea that 2on/2off is not a great dosing protocol. If I were using clen, I´d be using it for 6-12 weeks at a time, if I expected to get maximum results from it, but certainly, the most dramatic effects on fat loss appear to be in weeks 1-2. The reasons for the further increase in FFM around week 6 despite no changes in %fat or fat mass is not easily explained... It might be that clenbuterol can increases FFM through another nonreceptor-mediated pathway, which would be very good for us, since the anabolic effects would also be applicable in humans, despite the fact that animals often respond more dramatically to beta-agonist/antagonists, due to receptor properties.. However, clenbuterol is highly lipophylic and can also enter muscle tissue (12), so that could indicate a possible mechanism of work. Maybe that would explain the significant increase in FFM of 13 kg in at 8 wks in the study? Certainly, muscle protein synthesis (MPS) must be a part of it, since clen will increase MPS in your body (17)& But it has even been speculated that the growth-promoting effect of clenbuterol may be specific to muscle and that the drug may act in a not-yet-understood manner which circumvents (!) the physiological mechanisms responsible for the control of muscle growth (13). This may mean that clenbuterol can help blast you past "sticking points" in your training by circumventing the usual mechanisms by which anabolism is experienced! It is of note that both muscle composition and fiber size has been shown to increase with administration of clen (14).
