TRT Eligibility FAQ
5 questions answered about eligibility for testosterone replacement therapy.
Who qualifies for TRT?
You may qualify for TRT if you have two morning testosterone levels below 300 ng/dL along with symptoms of low testosterone such as fatigue, low libido, erectile dysfunction, depression, or muscle loss. Your physician will evaluate your complete medical history and rule out other causes before prescribing.
What testosterone level is considered low?
Most medical guidelines define low testosterone as a total testosterone level below 300 ng/dL, measured via morning blood draw. However, many TRT specialists consider levels below 400-500 ng/dL as suboptimal, especially when accompanied by symptoms. Free testosterone should also be evaluated alongside total T.
What is the optimal testosterone level on TRT?
Most TRT physicians aim for trough testosterone levels of 600-1000 ng/dL (measured the morning of your injection, before your next dose). Free testosterone should be in the upper quartile of the reference range. Optimal levels vary by individual — the goal is symptom resolution with minimal side effects.
Can you get TRT if you are under 30?
Yes, men under 30 can receive TRT if they have documented low testosterone. However, younger men should explore root causes first (sleep, stress, obesity, pituitary issues) and consider fertility-preserving alternatives like enclomiphene before committing to lifelong TRT. A thorough workup is essential.
Can women take testosterone replacement therapy?
Yes, women can benefit from low-dose testosterone therapy for symptoms like low libido, fatigue, and cognitive changes, particularly after menopause. Female TRT uses much lower doses (5-10mg/week vs 100-200mg/week for men). It should be prescribed by a provider experienced in female hormone therapy.
