What did @kokofaceyoga actually say?
The creator describes a weekly testosterone injection routine, explicitly stating "every Wednesday I do testosterone shot" and walking viewers through drawing up roughly 20 units (milliliters, presumably) from a vial, sterilizing the injection site, and self-injecting into the gluteal muscle. She mentions skipping estrogen but using testosterone, and stops short of showing the actual injection on camera.
To be clear about what this video is: it is a real-time demonstration of self-administered intramuscular testosterone, filmed and posted to a platform with millions of young viewers. The caption nods to medical supervision, but the content itself is a how-to walkthrough. That tension between the disclaimer and the demonstration is worth examining closely.
Does the science back this up?
Testosterone replacement therapy is a legitimate, FDA-approved treatment, and self-injection at home is clinically standard for patients who have been properly trained. The procedure itself, drawing from a vial and injecting intramuscularly into the gluteus, is textbook. The concern here is not whether TRT works. It does, when indicated.
The clinical evidence for TRT in women is actually more nuanced and contested than in men. A 2019 consensus statement by the Global Consensus Position Statement on the Use of Testosterone Therapy for Women (Wierman et al., published in the Journal of Clinical Endocrinology and Metabolism) found that low-dose testosterone has evidence for treating hypoactive sexual desire disorder in postmenopausal women, but noted that supraphysiologic dosing carries real risks including virilization, lipid changes, and cardiovascular effects. The "wellness optimization" framing that circulates on social media sits well outside what that consensus covers.
What did they get wrong (or right)?
Credit where it is due: sterilizing the vial top and injection site before drawing and injecting is correct practice. Not showing the actual injection to avoid platform violations suggests some awareness of content boundaries. Saying "consult a qualified medical professional" in the caption is the right message, even if the video content somewhat undercuts it.
What is missing matters more. The creator does not mention a diagnosis, a prescribing physician, or any indication for therapy. She does not clarify the concentration or actual dose of the testosterone she is drawing, describing it only as "20 millimeter, I guess," which is imprecise language that could genuinely confuse viewers about units. Intramuscular testosterone for women is dosed very differently than for men, and self-injection without proper training increases risk of nerve injury, infection, and injection-site reactions (Bhasin et al., 2010, New England Journal of Medicine). The casual framing of a medical procedure as a weekly wellness ritual normalizes hormone use without any clinical context.
What should you actually know?
Testosterone is a controlled substance in the United States and requires a prescription. It is not a supplement. Self-injection demonstrated casually on social media, without showing the prescription, the diagnosis, or the clinical supervision behind it, creates a misleading impression that this is something anyone can or should do at home on a schedule.
For women specifically, FDA-approved testosterone formulations do not exist in the U.S. as of 2024. Prescriptions are off-label. That does not make them wrong, but it means there is a real physician-patient relationship and ongoing monitoring that should be happening. Viewers who see this video and decide to source testosterone independently, or replicate the technique without training, face serious risks including infection, hormonal imbalance, and legal consequences.
The bottom line: what you are watching is a trained individual administering a prescribed medication, almost certainly under medical supervision we cannot verify from the video. What it looks like to an uncritical viewer is an invitation to try this themselves. Those are two very different things.
