Testosterone HRT for trans men: what TikTok gets right and wrong

What did @leemonline actually say?

In this reply video, @leemonline made three distinct claims about testosterone therapy. First, that continuing T is what keeps their body looking and functioning the way they want, including erectile function. Second, that they're willing to accept hair loss as a trade-off. Third, and most medically interesting: "stopping or missing my teetos is very fatigue-inducing," to the point of sleeping "for like a week straight." They also speculated, half-jokingly, that stopping completely might "make me go into a coma."

The tone is personal and anecdotal, which is fine. But anecdotes shared to 6,800 viewers carry weight, and the fatigue claim in particular deserves a closer look because it blends a real physiological phenomenon with some notable exaggeration.

Does the science back this up?

Partially, yes. The fatigue part has a real biological basis, though the severity described is likely exaggerated. The hair loss connection is well-established. The erectile function claim is more complicated than the video lets on.

When someone on exogenous testosterone misses doses, serum testosterone levels drop, sometimes sharply depending on the ester used. Testosterone cypionate, for example, has a half-life of roughly 8 days (Bhasin et al., 2010, New England Journal of Medicine). As levels fall, people commonly report fatigue, low mood, and reduced energy. This is a real, documented withdrawal-adjacent effect, particularly in individuals whose endogenous production has been suppressed by long-term exogenous T use.

However, sleeping "for like a week straight" from a missed dose is not consistent with what the pharmacokinetics suggest. You'd see a gradual decline, not an immediate crash into hibernation. The fatigue is real. The scale described here is probably personal hyperbole.

On hair loss: DHT-driven androgenetic alopecia is a legitimate concern with testosterone therapy, particularly in those with genetic predisposition. Rogan, which likely refers to Rogaine (minoxidil), is commonly used to slow this. That's accurate terrain.

What did they get wrong (or right)?

They got the general concept right. Missing testosterone doses after long-term use does cause fatigue. Testosterone does play a role in sexual function and body composition. DHT is connected to hair loss. These are real phenomena.

Where it gets shaky: the "coma" speculation, even framed as a joke, misrepresents what testosterone cessation actually does. Stopping testosterone does not cause loss of consciousness. What it can cause is a period of hypogonadal symptoms including fatigue, depression, reduced libido, and muscle loss while the hypothalamic-pituitary-gonadal axis slowly recovers, if it recovers at all after prolonged suppression (Ramasamy et al., 2014, Journal of Urology).

The erectile function claim also needs nuance. Testosterone contributes to libido and erectile function, but it's not the sole driver of erections. Vascular health, psychological factors, and nitric oxide pathways all play significant roles. Saying "I want to be able to have erections, so I'm keeping T" frames it as a direct on/off switch, which it isn't.

• Fatigue from missed doses: plausible and common
• Severity described (week-long sleep): almost certainly exaggerated
• Hair loss trade-off: accurate framing
• Erections depending entirely on T: oversimplified
• Stopping T causing a coma: inaccurate, even as a joke it could mislead

What should you actually know?

If you're on testosterone and you miss a dose or are considering stopping, here's what the evidence actually supports.

Missing a dose of testosterone cypionate or enanthate will cause a gradual decline in serum T levels over several days, not an immediate crash. Symptoms of low testosterone, including fatigue, low mood, and brain fog, may appear as levels fall. This is a documented experience, not drama.

Stopping testosterone entirely after long-term use is a more serious decision. Endogenous testosterone production is often suppressed after extended exogenous use (Coviello et al., 2004, Journal of Clinical Endocrinology and Metabolism). Recovery of the HPG axis is not guaranteed and can take months. For transgender men who have undergone long-term T therapy, this is particularly relevant because the baseline gonadal function may differ significantly from cisgender men with hypogonadism.

If you're experiencing significant fatigue from missed doses, that's worth discussing with a prescribing provider, not just accepting as an inevitable side effect. Dose timing, ester selection, and injection frequency all affect how dramatically levels fluctuate between doses.

Hair loss management with minoxidil is a reasonable and evidence-supported approach for those who want to slow androgenetic alopecia while maintaining T therapy (Messenger and Rundegren, 2004, British Journal of Dermatology).
