Hey, Jerome! The haps'?
Yes, 200 is actually quite low for someone your age. Your test' count should be at the very least 300. By way of comparison, at 60, my off-cycle ng/dL is right around 600. So there you are.
But, no, 200mg per week of synthetic test' is not an excessive amount. Moreover, 200mg per week is what your endro' prescribed and that is what it should remain unless and until you find it to be problematic, which I don't think you will. Never will I tell you to go against the advice of your physician, and you shouldn't listen to anyone who would advise you to go against the advice of your physician.
With that said, do you like your physician? Does he or she listen to you and explain things to you?
