During the two 'off' weeks, an ECA stack can be used as required. ECA will not cause such a pronounced down regulation and desensitization of the receptors, certainly not to the extent of clen. Ephedrine has a short half life in contrast to clen which results in times throughout the day where the betas will partially recover from stimulation by adrenaline and nor-adrenaline. Potency is also much weaker that that of clen, as it is not a specific agonist. Ephedrine is also thought to increase the conversion of endogenous/exogenous T4 to T3 through the activation of deiodinase enzymes responsible for this process. This is important as clen is known to slow the rate of T4 to T3 conversion. As a side note, some bodybuilders will use T3 concurrently with the Clenbuterol/ECA cutting cycle (together with certain anabolic/androgenic steroids no doubt!) in an attempt to at least maintain plasma T3 levels.
Hey guys you are absolutely ridiculous to think that this is safe for you. It’s very hard on athletes and bodybuilders so it should be about 45% harder on your body compared to theirs. The average athlete has exercise-induced bradycardia and high VO2 maxes… please be very very very careful because you don’t have any of this. In fact the increase in oxidant stress on your system may increase your chances of certain types of cancers. Remember almost all of you are not a trained athlete and there WILL be repercussions.
