they use the same receptors correct? so you cant cycle 2 weeks clen/2 weeks ephedra? ive been told it will work fine and that it shouldnt be done...?
yes, same beta receptors.
th reason for cycling clen (2 weeks on, 2 weeks of) is to allow your receptors to up-regulate
If you are taking eph in the 2 weeks off from clen, the recpeots are still getting hit and you are impairing the 'recovery process', therefore clen will not work as well when you are back on it after using eph for 2 weeks
