TRT on TikTok: separating hormone facts from hype

What did @bull52772 actually say?

The creator made two separate arguments. First, that anyone using pellets, gels, or patches for TRT is simply "wrong" and should be injecting instead. Second, that subcutaneous injections absorb more slowly than intramuscular ones, and that sub-Q is his personal preference because it uses a smaller needle. He then invited viewers to comment their "T-Day" so he could guide them on starting TRT online.

He framed the delivery method debate as a matter of personal preference in the same breath as calling non-injection methods wrong, which is a contradiction worth unpacking. The science on this is more nuanced than he let on, and the invitation to help strangers "start" TRT online without any mention of physician oversight is the part that should give you pause.

Does the science back this up?

The absorption claim is basically correct. Intramuscular testosterone does reach peak serum levels faster than subcutaneous. But "wrong" for gels and pellets? That's not what the evidence says.

A 2017 study by Pastuszak et al. in the Journal of Urology found testosterone pellets produced stable serum testosterone levels over three to six months with high patient satisfaction. Gels, while less predictable due to transfer risk and skin absorption variability, are FDA-approved and appropriate for patients who cannot or will not inject. A 2021 review by Ramasamy et al. in Sexual Medicine Reviews confirmed that all major delivery methods, injections, gels, patches, and pellets, are clinically effective for treating hypogonadism when properly monitored. The method that keeps a specific patient's levels in the therapeutic range and gets them to actually adhere to treatment is the right one for that patient.

On the sub-Q versus IM comparison, a 2017 paper by Olson et al. in the Journal of Clinical Endocrinology and Metabolism found sub-Q testosterone cypionate produced stable trough levels with less peak-to-trough variability than IM in some patients, which is actually an argument in favor of sub-Q, not just a neutral preference.

What did they get wrong (or right)?

He got the absorption mechanics broadly right, and the insulin-needle comparison for sub-Q is accurate and genuinely useful for needle-averse patients. Those are real points worth making.

What he got wrong is the blanket dismissal of other delivery methods. Calling pellets and gels "wrong" is not a clinical position, it's a preference stated as fact. Pellets in particular have a strong adherence argument: you get an insertion every three to six months and stop thinking about it. For some patients, that consistency beats weekly injections every time.

The bigger problem is the framing at the end. Offering to personally coach strangers on how to "start" TRT via TikTok comments, with no mention of blood work, physician supervision, or baseline hormone testing, is not health guidance. It's recruitment. TRT is a regulated treatment. Starting it without a proper diagnosis of hypogonadism, including two morning testosterone draws and a clinical evaluation, creates real risks including infertility, polycythemia, and cardiovascular strain. None of that was mentioned.

What should you actually know?

If you are considering TRT, the delivery method is one of the last decisions you make, not the first. The first step is confirming you actually need it through lab work and a licensed clinician, not a TikTok comment section.

• Sub-Q and IM injections are both effective and evidence-supported. The 2017 Olson et al. data suggests sub-Q may actually produce more stable levels for some patients, so the creator's preference has a scientific basis, even if he understated it.
• Gels and patches are not inferior for every patient. Transfer risk and skin variability are real concerns, but dismissing them entirely ignores legitimate clinical use cases.
• Pellets offer multi-month stability and are supported by outcomes data. They are not "wrong."
• Starting TRT suppresses your body's own testosterone production. This affects fertility. Any clinician-guided TRT conversation should include a discussion of this, especially for younger men.
• Hematocrit elevation is a known risk of TRT across all delivery methods. Regular monitoring is not optional, it is the standard of care.

The mechanics this creator described are not dangerous in isolation. The absence of any safety context around starting TRT is what makes this video a problem at scale, with 55,000 views and a comment-based recruitment pitch attached.
