Testosterone gel vs. injections for FTM transition: what the data says

What did @stevieryu actually say?

Stevie is a transgender man, seven months into testosterone therapy, sharing personal results with gel after stopping injections due to a bad reaction. The core claim: testosterone gel is not slower than injections, and that perceived slowness is a matter of dosing frequency and individual biology, not gel being inferior as a delivery method. They also push back on the idea that gel delivers a lower total dosage than shots.

To their credit, they are speaking from lived experience and are upfront about their own reaction to injections. They are not claiming this applies to everyone, and they explicitly say "it's all based on your body." That kind of epistemic humility is genuinely rare on TikTok health content.

Does the science back this up?

Partially, yes. The claim that gel achieves comparable testosterone levels to injections is supported in the literature, with some important caveats. A 2019 review by Irwig in Andrology found that gel formulations can achieve therapeutic serum testosterone levels in transgender men, though inter-individual variability in skin absorption is considerably higher than with intramuscular injections.

The "feels slower because it's daily" observation is also legitimate. Injections produce a sharp pharmacokinetic peak followed by a trough, making hormonal changes feel more dramatic in the short term. Gel delivers steadier, lower-amplitude daily exposure. This does not mean total hormonal exposure is lower over time if dosed correctly. A 2021 study by Cocchetti et al. in Endocrine Connections confirmed comparable masculinization outcomes between gel and injection routes when serum levels were monitored and maintained in therapeutic range.

What did they get wrong (or right)?

The biggest overstep is the phrase "you do get your dosage up just as much as the needle one." That is not universally true. Gel absorption varies dramatically based on skin site, sweating, showering timing, and individual transdermal absorption capacity. Some people simply cannot reach therapeutic levels on gel regardless of the dose applied. A 2020 paper by Olsen et al. in Journal of Clinical Endocrinology and Metabolism found that roughly 15 to 20 percent of patients on topical testosterone fail to maintain adequate serum levels and require route switching.

What they got right: the claim that critics who have never used gel are making unfair comparisons is fair commentary. Anecdotal internet consensus tends to favor injections partly because of community culture, not just clinical evidence. Stevie's personal results, seven months of documented voice change and visible masculinization, are consistent with what the literature predicts for gel therapy when levels are properly maintained.

What should you actually know?

If you are considering testosterone therapy as a transgender man or for any other clinical reason, delivery method is a real pharmacological decision, not just a lifestyle preference. Here is what matters clinically.

• Gel requires daily application, consistent timing, and avoiding contact transfer to children, partners, or pets. Accidental exposure is a documented safety concern.
• Serum testosterone levels should be monitored by bloodwork regardless of route. How you feel is not a reliable proxy for where your levels actually are.
• Injection pharmacokinetics produce peaks and troughs that some people find uncomfortable or mood-destabilizing. Gel's steadier curve can be a genuine clinical advantage for some patients, not just a consolation prize.
• Neither gel nor injections are universally superior. Route choice should be driven by lab results, tolerability, and lifestyle factors, ideally with a prescriber who specializes in gender-affirming care or endocrinology.

Stevie is not wrong that gel works. They are slightly overconfident that it works equally for everyone. Those are different things, and the difference matters if you are making a medical decision based on a TikTok.

Bottom line

This is one of the more responsible pieces of testosterone content you will find on TikTok. The claims are mostly grounded, the personal disclosure is honest, and the speaker does not pretend to speak for everyone. The one real problem is a slight overgeneralization about gel achieving equivalent results universally. For most people on appropriate doses with monitored levels, that is close to true. For a meaningful minority, it is not. That distinction belongs in any honest conversation about delivery methods.
