First of all I am 60 yrs old as of may, also due to cluelessness in my youth I have not used aas, though in recent years I have used moderate amounts of ph's. I just finishedl eight weeks of Novedes xt according to the directions on the bottle and I was making moderate strength gains, two days after stopping I bench pressed my usual amount and it went up like butter. I added weight and did it again added more weight. after adding 30 lbs and still lifting easily I stopped. It was mind blowing. Two days later I am no more achy than usual!
