@drleprovost's TRT safety tips pass the fact-check

What did @drleprovost actually say?

The advice here is pretty concise. @drleprovost tells viewers three things to do when injecting testosterone: keep the injection site clean, get regular blood work, and use "certified pharmaceutical grade testosterone" rather than unverified sources. That's essentially the whole message. No dosing claims, no cure claims, no stacking recommendations. For a TikTok aimed at a general audience, the scope is narrow and practical.

Worth noting: the caption mentions "don't buy it off the street," which the transcript softens to just using pharmaceutical grade testosterone. Either framing is pointing at the same real risk, which is counterfeit or contaminated testosterone from unregulated sources. It's a legitimate concern and one that gets underplayed in online TRT communities.

Does the science back this up?

Yes, on all three points, the evidence is solid. This isn't a controversial take. These are standard-of-care recommendations repeated in clinical guidelines from the Endocrine Society and the American Urological Association.

On injection site hygiene: intramuscular and subcutaneous injections carry a real infection risk when done at home without sterile technique. A 2019 review by Fink et al. in Translational Andrology and Urology specifically flagged skin preparation and sterile needle use as under-discussed but important safety factors in self-administered TRT. Abscess formation and cellulitis from contaminated injection sites are documented complications, not theoretical ones.

On blood work: testosterone therapy shifts hematocrit, red blood cell mass, and can affect lipid panels and PSA levels. The Endocrine Society's 2018 clinical practice guideline recommends monitoring hematocrit at 3 and 6 months initially, then annually. Skipping labs isn't a personal choice issue here, it's how you catch polycythemia before it causes a clot.

On pharmaceutical grade testosterone: counterfeit anabolic steroids and testosterone products are well-documented. A 2014 study by van der Nagel et al. in Drug Testing and Analysis found significant concentration variability and contamination in seized anabolic steroid products. Using unverified sources means you don't know what you're injecting.

What did they get wrong (or right)?

Honestly? They got the basics right. There's nothing clinically wrong in this video. The advice is accurate, appropriately brief, and doesn't overstep into dosing or disease-cure territory. Credit where it's due.

The one real criticism is what's missing rather than what's wrong. "Regular routine blood work" is vague. Viewers watching this who are new to TRT may not know that hematocrit monitoring is specifically time-sensitive, or that estradiol levels also warrant tracking given testosterone's aromatization to estrogen. Saying "get blood work" without any scaffolding around what or when leaves a gap that a motivated viewer will fill with whatever Reddit thread they find first.

The phrase "certified pharmaceutical grade" is also slightly imprecise. In the US, testosterone is a Schedule III controlled substance dispensed through licensed pharmacies, and there's no separate "certification" tier for pharmaceutical grade in the way the phrase might imply. Compounded testosterone from licensed 503A pharmacies is not equivalent to FDA-approved brand-name products. Viewers should understand that distinction when seeking care.

What should you actually know?

If you're on or considering TRT via injection, the three points in this video are a reasonable floor, not a ceiling. Clean injection technique matters and includes more than just a clean spot: it means a new needle every time, proper skin prep with alcohol and letting it dry, and rotating injection sites to prevent lipohypertrophy.

Blood work cadence matters more than just frequency. Early in therapy, labs at 3 months catch problems before they compound. A one-time annual check after years of stable therapy is different from skipping monitoring entirely in your first year. Talk to your prescriber about what panel makes sense for your situation.

And on sourcing: in the US, testosterone requires a prescription. If someone is selling it without one, or if a telehealth platform is not collecting labs and doing proper intake, those are red flags regardless of how pharmaceutical the product looks. Regulatory status matters for patient safety, not just legal compliance.
