ok 1st thing you need to do is go find the guy who gave you that advice and kick him in the nuts.

2nd never listen to him again.
Start out by reading this link and pay close attention to the pct section. After you run a pct you need to get bloodwork done and find out where your hormone levels are. Testosterone total & free. Estrogen total and sensitive, fsh and a few others. You might even be a candidate for trt at your age and since it made you feel that much better.
You have to be carful though especially on cycle because it's much easier to injury yourself, especially the shoulders at our age. I turn 52 in a few weeks. I am just past the 2 year mark from my shoulder surgery also so i speak from experience.
