cycling between clen/ECA/NYC...why?

[DepressiveJuice]

they all use the same receptors dont they? so if you use two weeks of clen and follow it up with two weeks of eca or nyc, your receptors wouldnt have a break since both eca and nyc use the same receptors that clen does. or am i getting screwed up here?

i think the clen works on a different receptor
