Bioidentical HRT for Women Over 40: Testosterone, the Dutch Test, and Why Mail-Order Hormones Fall Short

Cole Siefer (co-founder, host), Dr. Rose (naturopathic physician, acupuncturist)33:27HRT for WomenDecember 18, 2025

Episode Summary

Dr. Rose and Cole Siefer walk through the full picture of bioidentical hormone replacement therapy (BHRT) for women, covering why testing matters, how testosterone factors into female health, and the critical differences between bioidentical and synthetic hormones. The episode addresses common patient frustrations around being dismissed by conventional doctors and explains why a cookie-cutter approach (including online hormone services) falls short of what women actually need. The conversation also covers the hormonal triangle of thyroid, adrenals, and sex hormones, and how menopause-related weight gain, joint pain, and brain fog are connected to declining estrogen and testosterone.

Key Topics

  1. 1

    Why baseline blood work matters even before starting BHRT

  2. 2

    When a Dutch test (urine hormone metabolites) is needed and why it is more specific than serum testing

  3. 3

    Testosterone in female health: libido, motivation, mental clarity, and muscle tone

  4. 4

    Bioidentical vs. synthetic hormones: chemical identity, safety profile, and sourcing

  5. 5

    Why oral birth control is not an appropriate solution for menopausal symptoms

  6. 6

    At what age or symptom threshold women should consider coming in

  7. 7

    The hormonal triangle: thyroid, adrenal, and ovarian hormones interacting as a system

  8. 8

    Why online hormone services (e.g., mail-order BHRT) cannot replicate individualized care

  9. 9

    How BHRT is monitored and adjusted over time

  10. 10

    Peptides as a complement to BHRT for joint pain, sleep, and anxiety

Quotable Moments

Women can be symptomatic for 10 to 15 years before we look at the blood work and say, 'Oh yeah, you're menopausal.'

Dr. Rose

I have never seen that happen with all the women that we prescribe testosterone to. Dosed appropriately, I'm not seeing unwanted body hair.

Dr. Rose

There's no clinical reason why conventional medicine uses synthetic over bioidentical. Maybe it's cheaper, maybe it's approved by insurance. There's no clinical answer.

Dr. Rose

These glands have a complex relationship with each other. In conventional medicine there's this idea that the thyroid is off on an island, the adrenal glands are off by themselves, and the ovaries are separate. All of these hormones are in the blood together.

Dr. Rose

Whatever is given through a mail-order service, there's no individualized chemistry, no metabolism assessment, no medication review. We spend an hour with somebody after having the blood work done. It's so individualized, and that's what every woman deserves.

HRT for Women FAQ

Testosterone is critical for women beyond libido. It supports drive, motivation, mental clarity, and muscular strength. When dosed appropriately, it does not cause unwanted body hair. Most postmenopausal women have low testosterone and benefit from optimization.

The Dutch test measures sex hormone metabolites, showing what happens at tissue and receptor level rather than just blood levels. It is the gold standard for managing ongoing bioidentical HRT because it reveals how the body actually processes prescribed hormones.

Bioidentical hormones are chemically identical to your body's natural hormones, usually sourced from wild yam or soy. Transdermal bioidentical estrogen avoids the blood clot risk associated with oral synthetic estrogen, including birth control pills.

Yes. Declining estrogen affects connective tissue lubrication, causing joint pain along with dry skin, dry hair, and vaginal dryness. This lesser-known menopausal symptom improves when estrogen and testosterone are optimized through bioidentical HRT.

Mail-order services ship cookie-cutter doses without individualized testing, medication review, or chemistry assessment. A proper approach involves comprehensive blood work, an hour consultation, and precise dosing of specific hormone subtypes tailored to the individual.

Perimenopause can start at 35. Women with PCOS may benefit in their 20s or 30s. The perimenopausal transition offers the greatest preventive value: catching women in their late 40s to early 50s reduces future risk of dementia, cardiovascular disease, and osteoporosis.
