Let's say someone has been on trt for a year or more, and already have complete shutdown. If they were to continue with their regular dose of testosterone but take a one time dose of 5000iu, what might be experienced? I doubt it would increase testosterone since their testicles are atrophied and body has not been producing hormones for some time, but would it have any effects (not side-erects per say) on mood, libido, or ability to produce muscle? Obviously it might reverse some of the atrophy but I want to know about the subjective effects
