How much muscle can you actually gain on TRT in year one?

What did @user6976169776594 actually say?

The creator is responding to a viewer who says their doctor flagged testosterone levels of 1,165 ng/dL as too high while on 125 mg of testosterone per week. The creator's advice: tell the doctor to "kiss your ass" and find a new one. Their reasoning is that 1,165 is "barely just over high normal" and shouldn't cause problems as long as blood work stays consistent. They also disclosed that they personally maintain levels of 2,800 ng/dL and claim their blood work "always comes back perfectly fine." They criticized the doctor for focusing on numbers rather than symptoms, and questioned why no aromatase inhibitor (AI) was prescribed. While they stopped short of explicitly saying to ignore the doctor, the message was clear.

The creator's frustration with symptom-blind medicine has real merit in some corners of TRT practice. But the specific claims about what testosterone levels are "safe" deserve serious scrutiny.

Does the science back this up?

Partly, but not in the way the creator implies. The claim that 1,165 ng/dL is harmless with consistent monitoring has some clinical support, but 2,800 ng/dL is a different conversation entirely, and conflating the two is a problem.

The normal physiologic range for total testosterone in adult males is typically 300 to 1,000 ng/dL, with some labs extending the upper limit to 1,050 or 1,100 ng/dL. A level of 1,165 ng/dL is above reference range but not dramatically so. Studies on testosterone therapy, including Bhasin et al. (2010, New England Journal of Medicine), suggest that supraphysiologic levels do carry dose-dependent risks, including erythrocytosis, cardiovascular stress, and suppression of endogenous production. The TRAVERSE trial (Lincoff et al., 2023, New England Journal of Medicine) found that testosterone therapy in middle-aged and older men did not significantly increase major cardiovascular events at therapeutic doses, but participants were not being maintained at 2,800 ng/dL.

The creator's personal claim of running 2,800 ng/dL long-term with clean labs is unverifiable and pharmacologically unusual. At that level, hematocrit elevation and cardiovascular strain are well-documented concerns that do not always show up in a standard metabolic panel.

What did they get wrong (or right)?

They got one thing right: doctors who refuse to treat symptoms because a number falls slightly outside a reference range are a genuine problem in TRT care. The literature supports individualized treatment, and a blanket refusal at 1,165 ng/dL without clinical context is arguably too rigid.

But here is what they got wrong. First, equating 1,165 ng/dL with 2,800 ng/dL as similarly manageable is not supported by evidence. These are meaningfully different physiologic states. Second, the suggestion that "blood work always comes back fine" at 2,800 ng/dL ignores that standard panels often miss early polycythemia risk, left ventricular changes, or lipid shifts that require specialized testing. Shabsigh et al. (2005, BJU International) noted that hematologic and cardiovascular parameters need specific monitoring at supraphysiologic levels, not just a routine panel. Third, the AI advice, while not entirely wrong as a concept, is delivered without any nuance about when AIs are actually appropriate, and blanket AI use has its own risks including bone density loss and libido suppression.

What should you actually know?

If your testosterone level on TRT is modestly above the reference range and you feel well, a conversation about the risks and benefits with an informed physician is reasonable. Immediately dismissing a doctor over a cautious reading is not.

Reference ranges exist for a reason, even if they are imperfect. The Endocrine Society's clinical practice guidelines (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism) recommend targeting mid-normal physiologic levels during TRT, roughly 400 to 700 ng/dL, for most men. Levels above 1,000 ng/dL are associated with increased erythrocytosis risk, and hematocrit should be checked before and during therapy. A doctor flagging 1,165 ng/dL is not necessarily being unreasonable. They may be doing their job. The appropriate response is a conversation, not a dismissal. Seeking a second opinion from a TRT-experienced clinician is a reasonable step. Taking dosing cues from a TikTok creator who runs 2,800 ng/dL and frames it as no big deal is not.
