Testosterone boosters and TRT: separating sport medicine facts from hype

What did @dr.lisandroilla actually say?

Honestly, it's hard to tell. The transcript from this video is largely incoherent, referencing something called the "Bursus Association" and vague plans to make future videos. There are no specific, extractable medical claims about testosterone, TRT, or injury prevention in the words actually spoken.

The hashtags, however, tell a different story. Tags like #testosteronebooster, #prevenciónlesiones (injury prevention), and #trt strongly suggest the video was intended to connect testosterone therapy with athletic injury prevention. That framing matters, because it shapes what viewers walk away believing, even when the spoken content is muddled. We're fact-checking the implied message as much as the literal transcript here, and that's a legitimate approach when the hashtag strategy is clearly deliberate.

Does the science back up TRT for injury prevention?

The evidence connecting testosterone optimization to injury prevention is real but limited, and it is routinely overstated in sports medicine content on social media.

Testosterone does play a role in musculoskeletal health. It supports muscle protein synthesis, bone mineral density, and tendon collagen production. A 2016 review by Bhasin et al. in the New England Journal of Medicine confirmed dose-dependent improvements in muscle mass and strength in older hypogonadal men receiving testosterone therapy. Separately, research by Smith et al. (2012, Journal of Clinical Endocrinology and Metabolism) showed associations between low testosterone and increased fracture risk in aging men.

But here's the problem: showing that low testosterone is bad for musculoskeletal integrity is not the same as showing that testosterone supplementation prevents sports injuries in athletes or otherwise healthy individuals. Those are different questions, and the second one has almost no robust randomized controlled trial data behind it.

What did they get wrong, or right?

Because no specific factual claim was clearly made in the transcript, there is nothing to grade as definitively correct or incorrect from the spoken words alone.

What we can critique is the implied framing. Pairing #testosteronebooster with #prevenciónlesiones and #trt in a single post nudges viewers toward assuming testosterone boosters, whether OTC supplements or prescription TRT, are a validated injury prevention strategy. They are not. Over-the-counter "testosterone boosters" lack regulatory oversight and have negligible clinical evidence for any meaningful hormonal effect, according to a 2020 analysis by Balasubramanian et al. in the World Journal of Men's Health.

Prescription TRT for diagnosed hypogonadism is a different matter entirely. It has legitimate clinical indications. But conflating the two categories, as the hashtag set does, is misleading and potentially harmful to viewers who may self-medicate with unregulated supplements based on this content.

What should you actually know?

If you are a clinically hypogonadal patient, confirmed by two fasting morning serum testosterone draws below established thresholds, TRT under physician supervision has real, evidence-backed benefits for muscle mass, bone density, and quality of life. That is settled enough science.

If you are a healthy athlete looking to "boost" testosterone for injury prevention, the evidence does not support that approach. Supraphysiologic testosterone use carries documented risks including erythrocytosis, cardiovascular strain, and suppression of the hypothalamic-pituitary-gonadal axis, per a 2019 review by Mulhall et al. in the Journal of Urology.

Sports medicine content on TikTok has a real problem with scope-creep, where clinically appropriate treatments get repositioned as general performance enhancers. That gap between "treats a disease" and "optimizes a healthy person" is where patients get hurt, financially and physically.

• Always get baseline bloodwork before any hormonal intervention.
• Distinguish between diagnosed hypogonadism and "low-normal" testosterone in a healthy person.
• OTC testosterone boosters are not equivalent to, and should not be discussed alongside, prescription TRT.
