3% bf? Bro that is extremely diffcult and very unhealthy. Anything below 7% is unhealthy unless you are competing for a show.Originally Posted by gettingjackedandtan
Clen is not "anabolic", it is slighty anti-catabolic when on a restricted calorie diet.
If Clen is a true beta 2 receptor agonist, there is no reason for it not to be anabolic. Human muscles are full of beta 2 receptors ready to react under the order of Clenbuterol. Intense exercise can increase the beta 2 receptor density in muscles, creating a potential synergy. This would mean that training should increase the muscle sensitivity to Clen. The problem is, such results have not been observed, even in animals. In fact, animals given Clenbuterol and then intensively trained show very poor results. Later researchers demonstrated that the muscle building properties of Clen were not derived from a specific activation of beta 2 adrenoceptors as previously thought. Rather, Clen acts on a still unidentified atypical beta receptor. Then, it was thought that Clen would act on the newly discovered beta 3 receptors. Next, action on beta 4 was hypothesized. Both proved to be wrong as far as anabolism is concerned. In order to explain the lack of effect of Clen on anabolism in humans I think it is safe to conclude that we do not possess a significant amount of those atypical beta receptors in our muscles.
Of course, animal studies were performed with huge dosages starting with a rough equivalent of 50-60 tablets of 20 mcg a day. But even in increasing the dosages close to unsafe amounts (using a beta 1 receptor antagonist to minimize the side effects of Clen on the heart), no one ever experienced the strong anabolic action of Clen.
