Internet bro science about testosterone has evolved into something resembling a horoscope: If you read a list of symptoms of “low T” on the Internet nearly everyone will think they have a problem.

There’s a parallel problem where the testosterone replacement therapy industry has diverged from its original stated purpose of replacing missing testosterone. The trend now is to prescribe excessive doses, beyond what the person ever naturally had. It’s basically a doctor-prescribed steroids when overdosed, but that’s also what a lot of people think they want.

Even crazier, some of the TRT clinics are now prescribing anabolic steroid compounds that were only FDA approved for severe muscle wasting disorders and cancer patients. The subreddits even had scripts you could follow to trigger certain clinics to prescribe the steroids for a time.
