What did @alexeubank2.0 actually say?
Alex Eubank posted his testosterone bloodwork showing a result of 930 ng/dL and used it to respond to accusations that he takes more testosterone than he admits to. His core argument: 930 ng/dL falls within the "natural range" of 300 to 1100 ng/dL, therefore he could not be taking supraphysiological doses. He also mentioned lowering his dose recently and says he feels the best he ever has, mentally and physically.
To be fair, he is being more transparent than most fitness influencers. Posting actual bloodwork numbers is a step above vague denials. But the argument he's making, that being "in range" proves you're not on TRT or not on a significant dose, is where things get complicated fast.
Does the science back this up?
Not cleanly. The 300 to 1100 ng/dL reference range is real, but using it to argue against exogenous testosterone use is a logic problem, not a biology problem. Someone on a carefully titrated TRT dose can absolutely land at 930 ng/dL. That is, in fact, the entire goal of therapeutic TRT.
The American Urological Association (AUA) guidelines recommend targeting mid-normal physiological testosterone levels, typically 400 to 700 ng/dL for most hypogonadal patients, though some individuals do run higher under physician supervision. A 2018 paper by Mulhall et al. in the Journal of Urology noted that TRT patients on testosterone cypionate or enanthate commonly achieve levels between 500 and 1050 ng/dL depending on dose, ester, and timing of the blood draw relative to injection. A result of 930 ng/dL is fully consistent with someone on a moderate TRT protocol, not just natural production.
The reference range tells you where a result lands. It does not tell you how the person got there.
What did they get wrong (or right)?
The range cited, 300 to 1100 ng/dL, is approximately correct for total testosterone in adult males, though lab-specific reference ranges vary slightly. Quest Diagnostics and LabCorp both use ranges close to this. That part checks out.
What does not hold up is the implied conclusion. Saying "I'm in the natural range" while on TRT is technically possible but logically misleading. Being within a reference range does not mean your testosterone is endogenously produced. It means your number falls within a distribution that was established using both young and older men, many of whom are not optimized. A 22-year-old elite-level physique athlete sitting at 930 ng/dL could be completely natural. A 25-year-old on 150 mg/week testosterone cypionate could also land at 930 ng/dL, depending on injection timing and individual metabolism.
He also says he "lowered his dose," which implies there is, in fact, a dose. That is worth noting. He does not explicitly claim to be natural, to his credit, but the framing around "natural range" does conflate being within a reference range with being off exogenous hormones.
What should you actually know?
If you are trying to interpret your own testosterone bloodwork, or someone else's, a single total testosterone number tells you very little without context. Timing of the draw matters enormously on injectable testosterone protocols. Drawing blood at trough (just before the next injection) versus at peak (24 to 48 hours post-injection) can produce dramatically different results. A 2021 study by Ramasamy et al. published in the Journal of Sexual Medicine found that peak-to-trough variation on weekly injections can span several hundred ng/dL in the same individual.
LH and FSH levels are far more informative for determining whether testosterone is endogenously produced. On exogenous testosterone, LH and FSH are typically suppressed near zero because the hypothalamic-pituitary axis receives negative feedback. Eubank's post shows total testosterone only. Without those gonadotropin values, the bloodwork is incomplete for the purpose he is using it.
This does not mean he is lying about anything. It means the evidence he presented does not actually answer the question his critics were asking.
