Although it may be exasperated by running steroids/prohormones, declining T and the need to go on TRT it is not necessarily the result of running steroids/prohormones, and happens to many men who have never run a cycle.
Andropause is very real.
It is the male equivalent to menopause, except that menopause is market by a sudden absence (of menses), while andropause usually (but not always) starts in one mid 30s and continues to gradually decline thereafter. There tends not to be any suddenness, until one day you realize that you truly feel lethargic and usually suffer from reduced libido and erection quality issues (or, medically, no longer having raging hard-on syndrome).
