Common TRT mistakes: what the evidence says vs. what TikTok says

What did @otmenshealth actually say?

The creator made a straightforward case for smaller, more frequent testosterone injections using thin gauge needles, based on personal experience with scar tissue buildup from years of larger needle use. His core argument: "the science has evolved" and daily subcutaneous or shallow intramuscular injections with a 30-gauge, half-inch needle beat infrequent shots with bigger needles. He also mentioned a weekly dose range of "140 milligrams to 200 milligrams a week" and noted that scar tissue changes how testosterone absorbs. This is real-world, experienced-user advice, not clinical guidance, and that context matters when evaluating it.

Does the science back this up?

On the core needle-size and frequency argument, yes, largely. The evidence for smaller, more frequent injections producing more stable testosterone levels is reasonably solid. A 2021 paper by Grober et al. in the Canadian Urological Association Journal confirmed that subcutaneous testosterone injections with small-gauge needles produce comparable pharmacokinetics to intramuscular delivery with significantly less injection-site discomfort. The scar tissue concern is real too. Repeated intramuscular injections with large-bore needles are associated with progressive fibrosis in injection sites, a well-documented complication in the nursing and sports medicine literature. A 2010 review by Mishra et al. in the Journal of Clinical and Diagnostic Research described how repeated gluteal injections cause fibrotic contracture, exactly the "crunch crunch" the creator describes.

What did they get wrong (or right)?

He got more right than wrong, which is worth acknowledging. The move toward smaller gauge needles, rotating sites broadly across quads, shoulders, and lats, and daily dosing to flatten the peak-trough hormone curve are all consistent with current clinical thinking. Where he slides into imprecision is the dose framing. Stating "140 to 200 milligrams a week" as if this is a normal, standard range glosses over the fact that therapeutic TRT protocols vary widely by individual and are determined by bloodwork, symptoms, and clinical judgment, not a general range cited in a video. That framing, while not dangerous in isolation, normalizes doses that sit at the upper end of replacement therapy and nudge toward performance use. The sterile abscess comment is clinically accurate as a risk of poor injection technique, though the creator conflates it slightly with scar tissue as if they are the same problem. They are not. One is mechanical fibrosis, the other is an inflammatory or infectious complication.

What should you actually know?

Injection technique genuinely matters on TRT because this is, as the creator correctly says, not a short-term game. Research supports rotating sites broadly, using smaller gauge needles (27-30 gauge for subcutaneous or shallow IM), and more frequent dosing to reduce hormonal variability. A 2020 study by Pastuszak et al. in Urology found that men on more frequent lower-dose injection protocols reported better mood stability and fewer androgenic side effects compared to weekly or biweekly large-dose injections. The "vein care" analogy the creator uses is imperfect but the underlying point is sound: injection sites are a finite resource if you treat them badly. What this video does not give you is any guidance on whether these doses are right for you, how to monitor for complications, or when to involve a clinician. Those gaps matter. Injection site fibrosis and abscesses are manageable but they require medical attention, not a TikTok protocol adjustment.
