can receptor sites really burn out or be "tainted" as some would put it?
how long or how many cycles cause this or does correct post cycle and break from chemicals prevent this?
if so how is this possible?
is there a way to combat this?
Receptor down-regulation is a real phenomenon. TIME is the only real way to up-regulate androgen receptors. L-carnitine and a few other products may help shorten the time that AR's need to up-regulate, but other than that they simply need TIME to recover.
AR do not "burn out".
