I have been seeing a lot of recomendations for doing a rotating split of 2 wks Clen and then 2 wks ECA. It sounded like something I would like to do, but always had this thought stuck in the back of my head that for some reason this would not be very effective because of receptor downgrading since they are both Beta Agonists. Well, after doing some research I just found this older article that had some very interesting notions in it and wanted to see what everybody else thinks of it or from there own personal experiences.

And a brief summary: People often want to compare ephedrine to Clenbuterol. This is fine as long as you realize that they act in different ways. Clenbuterol is a specific beta-2 adrenergic agonist. As such, Clenbuterol interacts directly with beta-2 receptors on muscle and fat tissue. Ephedrine, on the other hand, is not a direct beta-2 agonist. In fact, ephedrine is a poor ligand for the beta-2 receptor. Instead, ephedrine stimulates the release of noradrenaline from sympathetic nerve terminals. The noradrenaline then goes on to interact with muscle and fat cells as a nonspecific adrenergic agonist. This simply means that noradrenaline activates beta-2 receptors, but also other beta-receptors as well as alpha-receptors. So to compare ephedrine and Clenbuterol you must take into account their differences.
The differences between ephedrine and Clenbuterol are important. For example, Clenbuterol is a very potent beta-2 agonist. As a result, within 14 to 21 days, the beta-2 receptors on muscle and fat cells will be drawn into the cell membrane to reduce their availability to Clenbuterol. Then, if you continue to take it, they will be disassembled all together, leaving you insensitive to Clenbuterol. It then takes at least 2-3 weeks for receptors to replenish themselves on muscle and fat cells. Once again, ephedrine is different with respect to down regulation. Ephedrine, being a much weaker agonist, does not cause rapid desensitization and/or down-regulation of adrenergic receptors.
The catching part: Ephedrine and Clenbuterol have two different, yet similar mechanisms of action. Nevertheless, don’t use Clenbuterol and ephedrine at the same time,
or even in an alternating fashion. Both drugs work through the beta-adrenergic receptor, however, Clenbuterol will shut down beta-receptors within a few weeks. Taking ephedrine at that time will do little for you. Better to use ephedrine from the start of your diet, only switching to Clenbuterol no further than 3 weeks out from the contest.
Please let me know what you guys think on this one.
