As someone who is generally against testosterone supplementation… hell no that’s a terrible comparison. How extrogenous testosterone affects the HPTA axis and the returns/dependence, is nowhere near what opiates do to your mu/delta opioid neuroreceptors.

Opiate neuroreceptors autodownregulate, for one, so that means tolerance/dependency gets worse over time. That doesn’t happen with testosterone at all. Also, TRT would not have diminishing returns, after you get past the first few weeks. Some of that is tuning E2 levels, etc; most of it is psychological result of expectations (think placebo effect).

You risk issues at common doses, like cardiovascular damage (which tend to be higher doses than TRT), but these issues don’t compare with opiates.
