Alex Eubank's TRT levels: what the numbers actually mean

What did @sulekchat actually say?

This clip is a repost of fitness influencer Alex Eubank discussing his recent bloodwork while on testosterone replacement therapy. He says his testosterone came back "right around 1500" — which he acknowledges is "a little bit higher than I would want" — and that he lowered his dose from 200 mg per week to 150 mg per week as a result. He also mentions he injected 100 mg the night before his blood draw, then fasted and tested in the morning.

To be clear: Eubank is describing self-directed dose adjustments on a controlled substance based on lab results. That context matters for evaluating everything else he says.

Does the science back this up?

He got the unit wrong but the concern right. He said "1500 kilograms per deciliter," which is not a real unit. He almost certainly meant 1,500 ng/dL (nanograms per deciliter), the standard way testosterone is reported in U.S. labs. That is not a minor slip — units matter in medicine.

As for whether 1,500 ng/dL is high: yes, it is. The normal adult male reference range is typically 300–1,000 ng/dL, though some labs cap it at 1,100 ng/dL. The American Urological Association's 2022 clinical guidance on testosterone therapy recommends targeting mid-normal physiological ranges and flags supratherapeutic levels as a reason to adjust dose or frequency. Bhasin et al. (2010, New England Journal of Medicine) showed dose-dependent increases in adverse events — including erythrocytosis and cardiovascular strain — at higher testosterone concentrations. Sitting at 1,500 ng/dL is meaningfully above therapeutic targets, not just slightly.

What did they get wrong (or right)?

He got the timing of his blood draw wrong in a way that inflated his result. Eubank says he injected 100 mg of testosterone the night before his blood work. For injectable testosterone cypionate or enanthate, peak serum levels typically occur 24–72 hours post-injection. Testing the morning after an injection likely caught him near peak concentration, not trough. Trough testing — drawn just before the next scheduled injection — is the clinical standard because it reflects the lowest point in the cycle and gives a more conservative, clinically meaningful number. Spratt et al. (2017, Journal of Clinical Endocrinology and Metabolism) specifically address timing artifacts in TRT monitoring.

On the other hand, he did the right thing by getting blood work and adjusting dose downward when levels came back elevated. That is exactly what responsible TRT monitoring looks like, at least in principle. Reducing by 50 mg weekly and planning a recheck in eight weeks is a reasonable interval, consistent with standard monitoring protocols.

What should you actually know?

If you are on or considering TRT, a few things from this clip deserve your attention. First, where you are in your injection cycle when you test changes your result significantly. Always test at trough unless your provider instructs otherwise. Second, 1,500 ng/dL is not a goal — it is a red flag. Sustained supratherapeutic testosterone raises hematocrit, which increases clotting risk, and may suppress HDL cholesterol. Corona et al. (2016, European Journal of Endocrinology) reviewed cardiovascular outcomes across TRT studies and found risk signals at higher concentrations. Third, dose adjustments on a controlled hormone should involve a licensed provider reviewing your full panel — not just total testosterone, but hematocrit, PSA, estradiol, and LH/FSH if relevant.

Eubank seems to be working with a provider to some degree, but the self-directed framing of this video normalizes adjusting controlled substances without explicit clinical oversight. That is not a template most people should follow.

Bottom line: what did he actually get right and wrong?

Credit where it is due: he tested, he acknowledged his levels were too high, and he lowered his dose. Those are responsible instincts. But he reported his units incorrectly, and his blood draw timing likely inflated his result, which means his actual trough level could be meaningfully lower than 1,500 ng/dL. Before changing a dose, that distinction matters. The eight-week retest plan is solid, but only if the next draw is timed correctly — at trough, not the morning after an injection.
