TRT for men: separating real benefits from the hype

What did @michaeltalbotvideo actually say?

He's 36, has testosterone levels bouncing between "300 and like low 300s to low 500s," and is asking other TRT users whether his numbers justify starting treatment. He's specifically curious whether his energy fluctuations, good one day and "completely zapped" the next, are caused by testosterone or something else entirely.

To be clear: he's not making strong medical claims. He's asking a question on the internet. That's actually the right instinct in some ways, though the wrong audience. But the framing of his question still contains some assumptions worth examining carefully, particularly the idea that his testosterone range is obviously low enough to explain his symptoms.

Does the science back this up?

His levels are borderline, and that's exactly where the evidence gets messiest. No, his symptoms are not automatically explained by testosterone levels in that range.

The normal reference range for total testosterone in adult men is roughly 300 to 1000 ng/dL depending on the lab, though the Endocrine Society sets its clinical threshold for hypogonadism at consistently below 300 ng/dL (Bhasin et al., 2010, Journal of Clinical Endocrinology and Metabolism). His high end of 500 ng/dL sits comfortably in the normal range. His low end of 300 is borderline but not definitively low.

More importantly, energy fluctuation is one of the least testosterone-specific symptoms a person can have. Sleep apnea, thyroid dysfunction, insulin resistance, depression, and poor sleep quality all produce identical presentations. A 2021 review in Andrology (Zitzmann et al.) specifically noted that symptom overlap between hypogonadism and these common conditions makes clinical diagnosis without repeated lab confirmation unreliable.

What did they get wrong (or right)?

He actually got the uncertainty right. His instinct that the energy swings might be "testosterone or something else" is clinically sound, and he deserves credit for not assuming TRT is the automatic answer.

What's less sound is anchoring the question to a single total testosterone number without mentioning free testosterone, SHBG, LH, FSH, or time of testing. Total testosterone alone tells an incomplete story. Two men with identical total T levels can have wildly different free testosterone levels depending on their sex hormone-binding globulin (SHBG). A man with high SHBG and total T of 450 ng/dL may have less biologically active testosterone than someone with total T of 350 ng/dL and low SHBG (Rosner et al., 2007, Clinical Chemistry).

He also doesn't mention when his levels were drawn. Testosterone follows a diurnal rhythm, peaking in the morning and dropping significantly by afternoon. The Endocrine Society recommends morning blood draws before 10 a.m. for accurate baseline assessment. Testing at different times of day could easily explain a 300 to 500 range without any real physiological fluctuation.

What should you actually know?

Borderline testosterone with nonspecific symptoms is a genuinely complicated clinical situation, and crowdsourcing TRT decisions on TikTok is a bad strategy regardless of how well-intentioned the commenters are.

A proper workup before considering TRT should include at minimum two fasting morning total testosterone draws on separate days, free testosterone, SHBG, LH and FSH to distinguish primary from secondary hypogonadism, a complete metabolic panel, thyroid function tests, and a sleep apnea screening. That's not excessive, that's standard of care (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism).

TRT is not consequence-free. It suppresses the hypothalamic-pituitary-gonadal axis, which matters significantly for a 36-year-old man with two kids who may want fertility options later. Exogenous testosterone reliably suppresses sperm production, sometimes permanently without intervention (Nieschlag et al., 2015, Asian Journal of Andrology). That conversation belongs with an endocrinologist or urologist, not a TikTok comment section.

• If his levels are consistently in the low-normal range after proper testing, a legitimate clinical discussion about TRT is reasonable.
• If his levels are driven by poor sleep, metabolic dysfunction, or obesity, treating the root cause often restores testosterone without exogenous hormones.
• Energy crashes that vary day to day are rarely explained by testosterone alone and warrant broader investigation first.
