Is TRT underdosing real, or just a social media narrative?

What did @trtover40 actually say?

The creator argues that most clinics deliberately start men on low testosterone doses not out of medical caution but out of self-protection. His framing: "if they give you too much they could lose their license, if they give you too little you're just a bit frustrated." He then describes a psychological trap where men on subtherapeutic doses blame themselves for fatigue, brain fog, and low motivation rather than questioning whether their dose is actually adequate.

This is a specific structural argument about how clinic incentives shape dosing decisions, and it deserves a specific response, not a generic "talk to your doctor" brush-off.

Does the science back this up?

Partly yes, and more than most endocrinologists would like to admit. The evidence that symptom resolution requires serum testosterone levels well above just "normal range" is real and growing.

A 2016 study by Bhasin et al. published in the New England Journal of Medicine (the Testosterone Trials) found that men treated to higher testosterone levels within physiological range showed meaningful improvements in sexual function, physical capacity, and mood compared to placebo, but the improvements were dose-dependent. Getting a man's total testosterone from 180 to 320 ng/dL, which is technically "normal," is not the same as getting him to 600 ng/dL, also technically normal. Both are "in range." Only one may resolve symptoms.

Khera et al. (2016, Journal of Sexual Medicine) noted that symptom thresholds for hypogonadism vary significantly between individuals, which means a population-level "normal" range does not reliably predict when a specific patient will feel better. The creator is not wrong about this biology.

What did they get wrong (or right)?

The creator gets the subjective experience right. The "almost" framing is actually a clinically documented phenomenon. Men who are partially treated report worse quality of life in some studies than untreated men, because they lose the psychological escape hatch of thinking treatment might help them.

Where he oversimplifies is the framing that clinics underdose primarily for liability protection rather than legitimate medical conservatism. That is a partial truth stretched into a villain narrative. Supraphysiologic dosing does carry real risks: erythrocytosis, cardiovascular strain, and suppression of fertility. Morgentaler et al. (2015, Mayo Clinic Proceedings) documented that while testosterone therapy is generally safe in hypogonadal men, individual cardiovascular risk assessment is genuinely necessary. Clinics that start conservatively are not just protecting themselves. They are also not wrong to do so.

The claim that staying low "leaves men stuck feeling almost better" is accurate for some patients. It is not a universal indictment of conservative starting doses.

What should you actually know?

If you are on TRT and still symptomatic, the first question worth asking is not "am I underdosed" but "what are my actual numbers." A trough total testosterone below 400 ng/dL with persistent symptoms is a legitimate conversation to have with your prescriber. Free testosterone matters too, particularly if SHBG is elevated, which labs often miss unless specifically ordered.

The creator's call to "stop asking if TRT works, start asking if yours works" is genuinely good framing. TRT is not a single treatment. It is a titrated intervention, and symptom persistence should prompt lab review, not patient self-blame.

However, the solution is not simply demanding a higher dose. Estradiol balance, thyroid function, sleep apnea, and iron status all affect how men respond to testosterone. A man who feels flat on TRT may be aromatizing aggressively, not underdosed. These are not interchangeable problems.

Work with a prescriber who measures trough levels, free testosterone, estradiol, and hematocrit, and who adjusts based on symptoms alongside numbers. If your clinic refuses to discuss your symptom picture at all, that is a fair reason to seek a second opinion.
