Testosterone's mood effects: TikTok's experience vs. science

What did @isntkyl actually say?

Honestly? Not much that can be fact-checked. The transcript from this 93.5K-view TikTok is a string of lyrics or vocal sounds, not medical commentary. The words captured, "her, her, her, her, oh, I'm ill," along with fragments that read like song lyrics, contain zero health claims about testosterone or TRT. The caption says "10/10 side effect" and notes the creator has "no one to talk to about it," which implies a personal experience with a testosterone-related side effect, but that experience never gets named or described in the spoken content.

This matters because the video is tagged under TRT content and has significant reach. The gap between what the caption implies and what the transcript actually delivers makes this impossible to fact-check in a traditional sense. We're working with a vibe, not a claim.

Does the science back this up?

There's nothing specific here to test against the literature. That said, the caption framing, a side effect rated "10/10" with social isolation around it, is worth taking seriously as a context clue. FTM individuals on testosterone therapy report a wide range of side effects, and the emotional component of navigating those changes without community support is well-documented.

A 2021 study by Unger et al. in the Journal of Clinical Endocrinology and Metabolism noted that transgender men on testosterone frequently report mood changes, shifts in libido, and physical changes that can be disorienting, particularly in the first year of therapy. Lack of access to informed peer support compounds the psychological burden. The creator's caption, "I got no one to talk to about it," maps onto findings that social support significantly affects how patients process hormone therapy experiences.

What did they get wrong (or right)?

There's nothing factually wrong here because there are no facts being stated. No dosage claims, no cure claims, no pseudoscience. What the creator got right, implicitly, is that side effects from testosterone therapy are real, can be surprising, and can feel isolating. That's accurate.

What's missing is specificity. A video with nearly 100,000 views that tags TRT content but offers no actual information, accurate or otherwise, is a missed opportunity at best and a source of confusion at worst. Viewers searching for FTM testosterone side effect information will find a video that gestures at an experience without describing it. That's not dangerous, but it's not helpful either. Credit where it's due: the creator isn't spreading misinformation. They're just not spreading information.

What should you actually know?

If you're on testosterone therapy, whether for gender-affirming care or hypogonadism treatment, side effects are real and varied. They include acne, voice changes, increased libido, mood fluctuations, polycythemia, and changes in lipid profiles. Some are more surprising than others, and many patients report feeling underprepared by their providers.

A 2020 review by Irwig in Endocrine Reviews found that long-term safety data for testosterone in transgender men is still accumulating, and that individualized monitoring matters more than any single protocol. If you experience a side effect that feels significant, whether it's "10/10" good or bad, that's worth a direct conversation with your prescribing clinician, not just a TikTok caption. Telehealth platforms that specialize in hormone therapy can offer more consistent access to that kind of follow-up than many in-person systems currently do.

• Do not adjust your dose based on social media content, including this video.
• A side effect that feels positive is still a physiological change worth tracking.
• Peer community matters for mental health outcomes during hormone therapy, and finding one is a legitimate clinical priority.
