Adding exogenous testosterone to the system might be very different than relying on the system's own T production. It's reasonable that there are more homeostatic effects (upstream and downstream of the T) when you're just working with your body's own testosterone even if it's on the high end of the ref range. You'd skip that when you inject it.
