What did @kmartfit actually say?
The creator claimed that "an average dose is anywhere between 100 and 250 milligrams" of testosterone for TRT, and that injection frequency matters, specifically calling out once-weekly and once-every-two-weeks protocols as "improper." The video then pivoted into a direct pitch for a specific clinic, Harley Med, promoting twice-weekly injections as the gold standard for optimization.
This is a promotional video dressed as educational content. The TRT dosage range mentioned is roughly in the ballpark of clinical practice, but the claim that once-weekly injections are categorically "improper" is not supported by evidence. It is a marketing position, not a medical one.
Does the science back this up?
Partially, but the nuance matters. The 100-250mg range loosely reflects what clinicians prescribe, though the lower end of actual physiologic replacement tends to cluster around 75-150mg weekly depending on the ester and individual pharmacokinetics. Twice-weekly injections do reduce peak-to-trough testosterone swings compared to once-every-two-weeks dosing, and that is a real clinical benefit.
However, calling once-weekly injections "improper" overstates the case. Ramasamy et al. (2014, Journal of Urology) and the Endocrine Society's 2018 clinical practice guidelines both support individualized dosing and frequency based on symptom control and serum levels, not a single universal protocol. Some patients maintain stable levels and symptom relief on weekly injections. The pharmacokinetic argument for more frequent dosing applies most strongly to every-two-week protocols, where the trough can drop significantly.
What did they get wrong (or right)?
Credit where it is due: the creator is correct that every-two-week injections are generally suboptimal. This is well-established. Testosterone cypionate and enanthate have half-lives of roughly 7-8 days, meaning a two-week dosing interval produces significant hormonal fluctuation, which many patients experience as mood instability, fatigue, and libido changes in the final days before the next injection.
Where the video goes wrong is in the blanket dismissal of once-weekly protocols. Bhasin et al. (2010, Journal of Clinical Endocrinology and Metabolism) showed that weekly injections of testosterone cypionate can maintain adequate serum levels in many hypogonadal men. Twice-weekly is often preferred, but "often preferred" is not the same as "the only legitimate approach." Framing it as a deficiency in the patient's current clinic, rather than an individual clinical decision, is misleading and conveniently serves as a lead-generation hook for a specific provider.
The dose range of 100-250mg also deserves scrutiny. The upper end of that range, 250mg weekly, exceeds what most endocrinology guidelines recommend for straightforward hypogonadism replacement and enters territory associated with supraphysiologic testosterone levels. Citing 250mg as part of a normal TRT range without qualification is not accurate clinical framing.
What should you actually know?
TRT dosing is genuinely individualized. The goal is to restore testosterone to a normal physiologic range, typically 400-700 ng/dL by most clinical benchmarks, while relieving symptoms. There is no single correct dose or frequency that applies to every patient. Injection frequency is a tool, not a moral judgment about your doctor's competence.
If you are on TRT and experiencing symptoms like fatigue, mood swings, or low libido near the end of your injection cycle, that is worth discussing with your prescriber. It may indicate that your current protocol needs adjustment. But the decision should be based on your lab values, symptoms, and clinical history, not a TikTok creator's clinic referral. Anawalt and Matsumoto (2022, New England Journal of Medicine) summarized the evidence clearly: personalized titration outperforms any fixed protocol across patient populations.
Also worth noting: this video ends with a direct solicitation, "Comment TRT down in the comments below," to funnel viewers to a specific paid service. That does not automatically make the content wrong, but it is a conflict of interest that should be disclosed and weighed accordingly.
