A friend of mine who works out said that it is best when stacking 1AD and Nor19 to take both for 2 weeks on/ 2 weeks off for 14-16 weeks and than take Tribestan for 3 weeks after. His reasoning is that your body won't shut down natural test production if you do it this way. He also said it's healthier and you won't get as much sides.

Is he speaking truth?
