What did @kid_addy_x actually say?
The creator's on-camera transcript doesn't actually address testosterone delivery methods directly. What they said on camera was about self-confidence and personal maintenance. The testosterone comparison, specifically the claim that injections produce "amazing and very fast" results compared to gel, appears in the caption only, not spoken aloud in the clip.
So right away, we're fact-checking a caption claim, not a verbal one. That matters, because captions often carry claims that wouldn't survive a second of eye contact with a camera. The core assertion is: injections are faster than gel, gel "will still get you there" but at a slower pace. That's actually a reasonable claim on its surface, and it deserves a fair look at the evidence.
Does the science back this up?
Partially, yes. Testosterone injections, particularly cypionate or enanthate, do produce higher peak serum testosterone levels than transdermal gels, and those peaks arrive faster after each dose. But "faster results" is doing a lot of work in that sentence, and the science doesn't fully support the implication that masculinizing outcomes happen quicker with injections over time.
A 2019 study by Spratt et al. in Transgender Health found that both transdermal and injectable testosterone effectively achieved therapeutic serum levels, but the pharmacokinetic profiles differed significantly. Injections create a peak-and-trough cycle, while gels maintain steadier, lower daily levels. A 2021 systematic review by Cocchetti et al. in Journal of Clinical Endocrinology and Metabolism found no significant difference in the rate of physical masculinization outcomes, such as voice changes or clitoral growth, between delivery methods when total testosterone exposure was equivalent. In other words, how fast you see results depends more on your total testosterone levels than on how it gets into your body.
What did they get wrong (or right)?
They got the general direction right but oversimplified the mechanism. Saying injections are faster isn't wrong if you're talking about how quickly serum levels rise after a single dose. But the implication that this translates to faster masculinization for trans men isn't well supported by comparative outcome data.
What the caption gets wrong, or at least glosses over, is that gel underperformance is often a dosing and absorption issue, not an inherent weakness of the delivery method. Skin absorption varies widely between individuals. Some people on gel achieve excellent levels. Some don't, because of skin pH, application site, or body fat distribution. The Spratt et al. data showed wide variance in gel absorption specifically. So the better framing would be: injections are more predictable, not necessarily faster in terms of physical changes.
There's also a real conversation to have about side effect profiles. Injections create testosterone spikes that some patients find cause mood fluctuations, acne flares, or erythrocytosis risk at higher rates than gel. That tradeoff gets no mention in the caption.
What should you actually know?
If you're considering switching delivery methods, the most important variable isn't injection versus gel in the abstract. It's your actual serum testosterone levels and how consistently you hit your target range. A person on gel who achieves stable levels in range may masculinize at the same rate as someone on injections, according to the comparative data available.
That said, injections do offer one practical advantage: compliance. Gel requires daily application, correct skin prep, and no transfer risk to others for several hours. Missing doses or applying incorrectly tanks your levels. Injections, given weekly or biweekly, remove a lot of that daily friction. For many trans men, that consistency is what actually drives better outcomes, not the delivery mechanism itself.
Any change to your testosterone delivery method should go through a clinician who can monitor your levels before and after the switch. Hematocrit, hemoglobin, and blood pressure should be checked regularly regardless of method. Self-directed switches based on social media impressions are not the move here.
The bottom line
The caption makes a claim that sounds intuitive but is not cleanly supported by outcome data. Injections are not proven to masculinize trans men faster than gel when total testosterone exposure is matched. They do produce higher, faster peaks per dose, and they may offer better real-world consistency for some people. The creator's enthusiasm is understandable, but the framing sets up a comparison that the clinical literature doesn't fully endorse. Gel isn't a consolation prize. It's a different tool with different tradeoffs.
