Female testosterone therapy at one month: what the science says

What did @grayson.smith12 actually say?

Grayson posted a one-month check-in on testosterone replacement therapy, prescribed after blood work confirmed "really low natural testosterone." She's using a topical testosterone cream applied daily and reports her main symptoms, "really bad fatigue and brain fog," have improved noticeably. She also preemptively addressed common fears, saying she hasn't grown "abnormal facial hair or gotten acne" from treatment. Her biggest reported win is no longer crashing hard in the 2-3 PM window. She framed the video explicitly as a personal update, not medical advice, closing with a note that this "might be a good option for you."

That last line is worth paying attention to. She's sharing an experience, but the framing nudges viewers toward self-identification, which matters when we're talking about a hormone that requires a confirmed diagnosis to prescribe responsibly.

Does the science back this up?

Mostly, yes, with some important asterisks. Low testosterone in women is a real clinical condition, and fatigue and cognitive complaints are among the most consistently documented symptoms. One month is also a reasonable window to start feeling some effects, though it's on the early end.

A 2019 systematic review by Davis et al. in The Lancet Diabetes and Endocrinology found that testosterone therapy in women improved sexual function and, to a lesser extent, wellbeing and fatigue, based on randomized controlled trial data. The brain fog piece is trickier: testosterone does influence cognitive function through androgen receptors in the brain, but the direct evidence linking low-dose female TRT to measurable cognitive improvement is thinner than the fatigue data. A 2021 review by Islam et al. in Nutrients noted that androgen deficiency correlates with cognitive complaints in women, but causation via supplementation is less clearly established.

The afternoon energy crash she describes is also plausible. Cortisol and testosterone interact, and some research suggests low androgens may amplify midday cortisol dips, though this mechanism in women specifically needs more study.

What did they get wrong (or right)?

She got the basics right. Blood work before prescribing, a doctor involved, a topical formulation, clear reporting of both positive effects and at least one side effect (increased hunger). That's a more responsible framing than most TRT content on TikTok.

The facial hair and acne claim deserves nuance. She says she hasn't experienced either, which is true for many women on low-dose testosterone cream, but these are real and documented risks, not myths to dismiss. A 2021 trial by Huang et al. in Menopause found androgenic side effects, including acne and hair changes, occurring in a meaningful minority of women using topical testosterone, particularly at higher doses. One month is also an early window for these effects to appear, as androgenic skin changes can take several months to develop.

Her comment that balancing testosterone helps with "migraine" is the weakest link in the video. There is some observational data suggesting hormonal fluctuations trigger migraines in women (particularly estrogen drops), but testosterone as a migraine treatment is not established. Framing it as a known benefit is an overreach not supported by current clinical evidence.

What should you actually know?

Female testosterone deficiency is under-discussed and under-diagnosed, but that doesn't mean every woman with fatigue and brain fog has low testosterone. Those symptoms overlap with thyroid dysfunction, iron deficiency anemia, sleep disorders, depression, and a dozen other conditions. Blood work is not optional here, it's the starting point, which Grayson did correctly.

Topical testosterone cream for women is typically prescribed at doses far lower than those used in men. It is not the same formulation or dose, and viewers should not assume their male partner's gel or patches would work the same way. The FDA has not approved any testosterone product specifically for women in the United States as of 2024, meaning prescriptions are off-label, which is legal and common but means dosing and monitoring standards vary by provider.

One month of feeling better is encouraging but not a complete picture. Testosterone therapy requires ongoing monitoring of blood levels to avoid supraphysiologic dosing, which carries its own risks including cardiovascular and hematologic effects. Anyone considering this should be working with a provider who checks levels regularly, not just at the start.
