@smoothest_criminal I don’t know where you and @xevox get your training guidelines from, but it is absolutely not recommended to overtain.
Overtraining, among other things, raises cortisol, thus lowering testosterone. It provides no added benefits and It breaks down muscle (catabolism) instead of building it. It is counterproductive and puts you at greater risk for injury, and negative effects, as you’ve related.
Overtraining has to do with how many sets you perform. From the NCSF guidelines, each training protocol has different set limits, e.g. strength training has a set limit of 24 sets, hypertrophy a limit of 40 sets.
With all due respect, both of you sound clueless when it comes to training. Do you get your training guidelines from blogs and forums?
To answer your question, I think it’s harder to overtain on TRT because you are exogenously raising your testosterone levels, but I still think it’s not recommended.
Why did you go on TRT to begin with? I have to wonder whether you were overtraining to the point of exhaustion and that caused high cortisol and low T.
If I were you, I’d structure workouts more carefully. Stick to a regimen and specific set limits. Recovery and repair are more important than the workouts.
Your objective is to stimulate the muscle, not kill it. I don’t picture you made great gains working out in the manner you have. If you have made gains, I’d say they’d be better if you followed a proper training regimen.
