My brother (mid 30’s) has been feeling fatigued, irritable and just overall rundown. No issues with libido but, is having a problem with getting and keeping erections. He has a pretty easy office job but, by his own admission does tend to push it with training. I think his training along with trying to stay lean all the time may be the biggest factors.
Any specific tests/labs worth getting that may give him some direction?
Also, from where Quest, Labcorp etc.?
