TRT coaching claims on TikTok: what the science actually says

What did @coachedbyzane actually say?

Zane's core argument is that 250mg of testosterone per week is not a cycle, just TRT for most people, and that anyone serious about bodybuilding gains should start at 350mg instead. He says 250mg won't make you "look like a bodybuilder" or produce "crazy size gains." The implication is clear: if you want results, go higher.

This is a common position in bodybuilding circles, and it's not entirely without basis. But the way it's framed collapses an important distinction between therapeutic dosing for a diagnosed medical condition and performance enhancement, and that matters a lot more than Zane seems to think.

Does the science back this up?

Partially, but the framing is off in ways that could genuinely mislead people. Clinical TRT doses typically range from 75mg to 200mg per week, depending on the patient, their baseline testosterone levels, and the protocol. 250mg already exceeds standard therapeutic dosing for most men.

The landmark Bhasin et al. (2001, New England Journal of Medicine) dose-response study found that 300mg per week of testosterone enanthate produced significant increases in lean mass and strength in healthy young men, and 600mg produced more. So Zane is right that 350mg will likely produce more visible hypertrophy than 200mg. But framing 250mg as "just TRT" erases the fact that supraphysiologic dosing, even at 250mg, carries cardiovascular, hematologic, and endocrine risks that scale with dose and duration. A 2023 meta-analysis by Grandahl et al. in Andrology confirmed dose-dependent adverse effects on lipid profiles and hematocrit even at moderate supraphysiologic doses.

What did they get wrong (or right)?

He got one thing right: there is a real pharmacological difference between replacing testosterone to normal physiologic levels and using it to push above those levels for performance. That distinction is real and worth making.

But he got the framing wrong, and arguably dangerously so. Saying 250mg is "just gonna be TRT" conflates a medically supervised treatment for hypogonadism with recreational hormone use. Actual TRT is prescribed based on lab values, symptoms, and clinical judgment, not a weekly milligram target someone heard on TikTok. For a man with naturally low testosterone, 100mg per week might restore normal levels. For someone with normal baseline testosterone, 250mg per week will push them significantly above the physiologic range. Calling that TRT is inaccurate.

His suggestion that 350mg is a "way better starting point" for a cycle is particularly irresponsible. Recommending specific doses to a general audience with unknown health histories, no lab context, and no physician oversight is not coaching. It's unsupervised medical advice.

What should you actually know?

The clinical definition of TRT is not a fixed milligram number. It is a personalized protocol designed to restore testosterone to the normal physiologic range, typically 300 to 1000 ng/dL, based on your own bloodwork and symptoms. The dose required to achieve that varies significantly between individuals.

250mg per week of testosterone cypionate or enanthate will push most men with normal baseline testosterone well above the upper physiologic range. That is by definition supraphysiologic dosing, which is what bodybuilders use in cycles, not what endocrinologists prescribe for hypogonadism. Bhasin et al. (1996, NEJM) established that even 600mg per week did produce substantial muscle gains, but also suppressed natural testosterone production entirely and altered lipid profiles. The gains Zane is promising come with tradeoffs he does not mention.

Anyone considering testosterone use for any reason, whether for hypogonadism symptoms or performance goals, should be working with a licensed medical provider, getting baseline labs, and monitoring hematocrit, lipids, blood pressure, and hormonal markers throughout. No TikTok coach can substitute for that.

The bottom line

Zane is working with a real pharmacological concept but applying it sloppily and in a way that minimizes legitimate health risks. The "250mg is just TRT" framing is wrong on clinical grounds and potentially harmful if it normalizes supraphysiologic testosterone use without medical supervision. The recommendation to start a cycle at 350mg directed at a general audience is the kind of content that belongs behind a clinical consultation, not a TikTok comment box.
