I don’t think that the body can tell whether its testosterone is endogenous or exogenous…it just knows that the levels are too high! When the levels get too high it tries to decrease production. Now I don’t know if it decreases LH or it uses some other mechanism. It seems apparent that almost everyone that gets an effect, notices a taper off of peak effects. This indicates to me at least, some compensation going on. Perhaps best results will be found with cycling the time on and time off. That will be up to the experimenters to try. I am indeed intrigued with the concept, but am currently experimenting with the thread on GH stimulation ( 500mg L-carnitine with 25 mg ornatine, I think the thread is called “Fountain of Youth”) and don’t want to have too many variables floating around.
also if the increased testosterone exacerbates the conversion to DHT and increases hair lose for those prone to it.
