FAQ

Common TRT questions from users researching clinics and treatment options.

What is testosterone replacement therapy (TRT)?

TRT is a medical treatment that restores testosterone levels in men diagnosed with low testosterone, also called hypogonadism. It is prescribed and monitored by a licensed provider.

What are the symptoms of low testosterone?

Common symptoms include fatigue, low sex drive, erectile dysfunction, reduced muscle mass, increased body fat, brain fog, mood changes, and slower recovery. Lab testing is required because symptoms overlap with other conditions.

What testosterone level is considered low?

Many guidelines use around 300 ng/dL as a reference point, but diagnosis usually requires two separate morning blood tests plus symptoms consistent with testosterone deficiency.

What is the difference between total testosterone and free testosterone?

Total testosterone includes both protein-bound and unbound hormone. Free testosterone is the unbound portion your body can use, so symptoms can still occur with normal total levels if free testosterone is low.
