Gel vs. injections for FTM testosterone: what the data says

What's this video probably claiming?

Based on the caption framing "which ONE IS BEST" alongside hashtags like #androgel and #shotday, this video is almost certainly positioning testosterone injections as superior to topical testosterone gel for FTM (female-to-male) transgender men pursuing masculinization. The creator, operating as a "trans coach," is likely arguing that injections produce faster muscle gains, better body composition changes, or more consistent hormone levels. This kind of head-to-head framing is extremely common in FTM fitness communities on TikTok, where anecdotal experience often gets packaged as clinical guidance. The problem is that "best" depends entirely on the individual, the goal, and the clinical context. A trans coach with personal experience is not the same as a prescribing clinician reviewing your labs. That distinction matters more than any injection schedule preference.

What does the science actually show?

The honest answer is that both delivery methods can achieve therapeutic testosterone levels when dosed appropriately, but they have meaningfully different pharmacokinetic profiles. Testosterone cypionate or enanthate injected intramuscularly or subcutaneously produces a peak within 24-48 hours and a trough before the next injection, creating a supraphysiologic-to-low swing that some people feel acutely. Testosterone gel (like AndroGel 1% or 1.62%) produces steadier serum levels day to day, which some studies suggest may be preferable for mood stability. A 2019 study by Hembree et al. in the Journal of Clinical Endocrinology and Metabolism confirmed both methods achieve equivalent masculinization endpoints over 12-24 months including voice deepening, clitoral enlargement, and body fat redistribution. Auer et al. (2018, Andrology) found no statistically significant difference in lean mass gains between injection and gel users when total testosterone exposure was matched. The "injections are better for gains" narrative has more gym culture behind it than peer-reviewed support.

Where does the social media noise diverge from clinical reality?

The biggest divergence is the conflation of bodybuilding logic with gender-affirming HRT. In the FTM fitness TikTok space, injection protocols are often discussed using language borrowed from cisgender male performance enhancement communities, including weekly injection timing, peak chasing, and the idea that higher or more frequent dosing equals better results. This is misleading for several reasons. First, FTM testosterone therapy is typically managed to maintain serum testosterone in the physiologic male range (300-1000 ng/dL per Endocrine Society guidelines), not to maximize anabolism. Second, gel transfer risk to partners and children is a real clinical concern that rarely gets mentioned in these videos. The FDA has issued warnings specifically about secondary exposure via skin contact. Third, cost and insurance coverage differ significantly by formulation, and that practical reality shapes real-world access more than any "which is best" framing acknowledges.

What should you actually know?

If you are an FTM individual on or considering testosterone therapy, the delivery method that works best for you is the one you will use consistently, that your prescriber can monitor appropriately, and that fits your life. A 2021 retrospective by Deutsch et al. in Transgender Health found that adherence, not delivery method, was the strongest predictor of achieving target testosterone levels. Subcutaneous injections, which are less commonly discussed in lay content, have grown in clinical popularity because they produce slightly lower peak-to-trough variation than intramuscular and are easier for self-administration. If a creator is telling you injections will produce dramatically better physique results than gel without referencing your baseline labs, your dosing schedule, or your prescriber, that is fitness content dressed up as medical guidance. Get your labs checked. Talk to a clinician who specializes in gender-affirming care. The answer to "which is best" is not a TikTok format answer.
