I think by definition testosterone replacement therapy (TRT) is Testosterone Replacement Therapy. If you are at higher than normal levels, this exceeds replacement dosage in theory. That doesn't mean some people or their bodies may not find the best "new balanced environment" at levels a bit above what most consider normal. There's a lot of moving parts and getting the system solid and balanced at different point when the original equilibrium is shot seems a blend or art/science/experience. My unprofessional opinion is that if you are monitoring bloods and vitals with care, you are probably okay but as others have said, my word means nothing to YOUR health at the end of the day.
