so are you saying stack eca with t3 one week then the next just eca..if so why is that
fat loss drugs like clen and t3 tend to down regulate quickly and lose their effectiveness, basically you body gets used to them. and if you stay on very long that is never easy on you thyroid.
the rational has allways been to alternate t3 and clen or t3 and ECA 2 weeks on 2 weeks off, some do 2 days on 2 days, to keep you body from desensitizing. because they work through slightly different mechanisms.
hugeandripped could no doubt give you a much more loquacious answer, but that is basically the gist of it
