What did @dr.anika.ackerman actually say?
The creator, presenting herself as a physician, offered three categories of practical HRT advice for women. On progesterone, she said it can be used by anyone regardless of uterine status and called it "nature Xanax" for sleep and anxiety. On testosterone, she suggested using low-dose men's gel products as a cheaper alternative to compounding pharmacies, and said it should be applied in the morning to avoid insomnia. On estrogen, she clarified that vaginal estrogen can be used alongside a patch without "doubling up" systemically, and that patches absorb better on the buttocks than the abdomen.
These are presented as provider-facing tips a patient can bring to their appointment, not self-prescribing instructions. That framing matters for evaluating the claims.
Does the science back this up?
Mostly, yes, with some important caveats. The core claims about progesterone's sedative properties, vaginal estrogen's low systemic absorption, and patch placement are reasonably well-supported. The testosterone timing claim has plausible mechanistic logic but limited direct evidence in women.
Progesterone's sleep-promoting effects are well-documented. A 2008 study by Schussler et al. in Gynecological Endocrinology confirmed that oral micronized progesterone increases NREM sleep stages, likely through its conversion to allopregnanolone, which acts on GABA-A receptors. That is the actual mechanism behind the "nature Xanax" comparison, and it is a reasonable one, though "Xanax" implies anxiolytic potency that the evidence only partially supports.
On vaginal estrogen, the North American Menopause Society (NAMS) 2023 position statement confirms that low-dose vaginal estrogen results in minimal systemic absorption and does not require progestogen protection in most women. Using it alongside a systemic patch is standard practice in genitourinary syndrome of menopause (GSM) management.
Patch placement on the buttocks versus the abdomen is supported by pharmacokinetic data. A 1994 study by Chetkowski et al. in Obstetrics and Gynecology found that buttock application produced higher and more consistent estradiol levels than abdominal sites in some formulations.
What did they get wrong (or right)?
The testosterone section deserves the most scrutiny. Recommending that women use men's testosterone gel products is not straightforwardly wrong, but it is clinically messier than presented. Men's gels are not FDA-approved for use in women, and dosing precision is harder because the concentrations are calibrated for male physiology. The creator acknowledges needing to do a separate dosing video, which is the right instinct, because dose matters enormously here.
The claim that progesterone "can be given to anyone even if you don't have a uterus" is where reasonable physicians disagree. The traditional indication for progesterone in HRT is uterine protection against estrogen-driven endometrial hyperplasia. Using it purely for sleep or anxiety in someone without a uterus is an off-label choice with some evidence but not universal guideline support. It is not dangerous, but calling it universally appropriate glosses over individualized risk-benefit conversations.
The morning testosterone timing advice is mechanistically sensible since testosterone can be energizing, but there is no strong randomized evidence in women specifically comparing morning versus evening application for sleep outcomes. It is reasonable clinical advice, not an established fact.
The patch-on-the-buttocks recommendation is genuinely useful and underreported. Credit where it is due.
What should you actually know?
If you are on HRT or considering it, this video is not a bad starting point, but it compresses nuance in ways that could matter to your individual situation. A few things worth knowing before your next appointment.
- Vaginal estrogen for GSM symptoms is considered safe even in breast cancer survivors by many oncology guidelines, including ACOG 2022, though patients should discuss with their oncologist.
- Progesterone for sleep is a real effect, but oral micronized progesterone (like Prometrium) is the form studied for this. Synthetic progestins like medroxyprogesterone acetate do not share the same mechanism and should not be assumed equivalent.
- Men's testosterone gel used off-label in women introduces compounding challenges of its own, including contamination risk for partners and children. It is not automatically simpler than a compounded product.
- Patch absorption can vary by skin site, individual metabolism, and adhesion. If your levels are inconsistent, site rotation and placement are legitimate things to discuss with your provider.
- None of these tips replace a hormone panel and a conversation with a clinician who knows your history.
