Testosterone levels are sharply declining in the US for reasons that are not well understood. And testosterone for is an absolutely critical hormone for men. If somebody starts at the low end, which at this point is going to be many, if not most, Americans, then testosterone supplementation is going to significantly and genuinely improve their wellbeing. There are numerous side effects, which are dealt with with other drugs (which is why steroids/testosterone often turn one into a walking pharmacy), but addiction is most certainly not one of those side effects.

There's no "falsely improved wellbeing". It's absolutely genuinely improved wellbeing, in the same way that if somebody was significantly deficient of some vitamin or nutrient, then supplementing it would similarly "genuinely" improve their wellbeing. This is why plummeting testosterone levels are a very serious thing. Because a certain minimum level is necessary for reasonable quality of life, and supplementation or increasing it naturally is very non-trivial.
