A Patient Guide

New to hormone replacement therapy?

“Replacing all of our deficient hormones — thyroid, testosterone, DHEA, and estradiol — to the levels we had in our youth is beneficial to both our health and quality of life.”
— Neal Rouzier, MD

For Women

Perimenopause & menopause are not a personality change.

Estrogen, progesterone, and testosterone begin shifting in your late 30s — long before your last period. The symptoms (sleep loss, anxiety, weight gain, low libido, brain fog, hot flashes, joint aches) are real, they are physiological, and they are treatable. Modern bioidentical HRT is one of the most well-studied tools we have for protecting long-term cardiovascular, bone, brain, and metabolic health.

For Men

Andropause is real — and almost no one is told.

Menopause is widely discussed; its male equivalent, andropause, is almost ignored. From age 30 onward, testosterone falls roughly 1% per year. The result — fatigue, lost drive, weaker workouts, low libido, brain fog, mood changes — is too often dismissed as “normal aging” or treated with antidepressants. It is not normal, and it is not inevitable. Bioidentical testosterone therapy, done correctly, is safe and protective.

The Science

What is bioidentical hormone therapy?

Bioidentical hormones are structurally and chemically identical to the hormones your body produces on its own. Your receptors recognize them, your body metabolizes them the way nature intended, and the side-effect profile is dramatically better than the older synthetic hormones used in the studies you may have heard scary headlines about.

At Body Tonic RX we use only pharmaceutical-grade bioidentical hormones — testosterone, estradiol, progesterone, thyroid, and DHEA — sourced from licensed U.S. pharmacies and dosed to physiologic, youthful levels under provider supervision.

Cardiovascular protection

Healthier cholesterol, blood pressure, and vascular function.

Lean muscle & strength

Easier to build muscle, harder to gain visceral fat.

Sharper mind & mood

Better focus, memory, motivation. Fewer mood swings and anxiety.

Deep, restorative sleep

Falling asleep faster, staying asleep, waking refreshed.

Libido & intimacy

Restored desire, performance, and sexual satisfaction.

Skin, hair & vitality

Improved collagen, hydration, hair quality, and overall glow.

The Key Hormones

Which hormones decline with age — and what they actually do.

Both

Testosterone

The primary hormone of strength, libido, drive, and lean muscle — essential for men AND women. Through conversion to estradiol it also supports bone density, mood, and cardiovascular health.

Common low-hormone symptoms

  • Low libido and sexual satisfaction
  • Fatigue and lost drive
  • Loss of muscle, increased belly fat
  • Brain fog, low motivation, mood changes
  • Poor recovery, weaker workouts

Both

Estrogen (Estradiol)

For women, estradiol governs cycle, skin elasticity, vaginal and urinary health, bone density, cardiovascular protection, and cognitive function. For men, the small amount converted from testosterone is essential for libido, erections, bone strength, and heart health — which is why we do NOT routinely use estrogen blockers in men.

Common low-hormone symptoms

  • Hot flashes and night sweats
  • Vaginal dryness, painful intimacy, recurrent UTIs
  • Sleep disruption, mood swings, anxiety
  • Dry, thinning skin and hair
  • Bone loss, joint aches

Women

Progesterone

The calming, sleep-supporting hormone. Balances estrogen, protects the uterine lining, supports mood, and is often the first hormone to decline in perimenopause.

Common low-hormone symptoms

  • Insomnia, restless sleep, 3 a.m. wake-ups
  • Anxiety, irritability, PMS
  • Heavy or irregular periods
  • Breast tenderness and bloating

Both

Thyroid (T3 / T4)

Your metabolic thermostat. Without optimal thyroid, no other hormone works correctly. Regulates temperature, energy, weight, mood, hair, and cognition.

Common low-hormone symptoms

  • Fatigue and unexplained weight gain
  • Cold hands, cold feet, cold all the time
  • Hair thinning, dry skin, brittle nails
  • Slowed thinking, low mood
  • Constipation and sluggish digestion

Both

DHEA

A precursor your adrenals make less and less of after 30. Supports immune function, stress resilience, cognition, libido, and is foundational to testosterone and estradiol production.

Common low-hormone symptoms

  • Chronic stress and burnout
  • Reduced libido and stamina
  • Slower recovery from illness
  • Loss of vitality and motivation

A Common Story

“My doctor said my labs are normal.”

Most primary care physicians use lab reference ranges that span every adult between 20 and 90 — which means a 45-year-old can be at the bottom of the range and still be told she's “fine.” Normal is not optimal.

A healthy 25-year-old man typically runs testosterone around 800–1000 ng/dL. A 50-year-old in the “normal” range may be at 280 — technically inside the lab cutoff, but a long way from where his body wants to be. The same is true for free testosterone in women, progesterone, thyroid, and DHEA.

We measure comprehensively — and we treat to physiologic, youthful levels, not just to the lowest passing grade on a lab printout.

How HRT Is Delivered

Multiple routes — tailored to you.

Subcutaneous injections

Daily or twice-weekly micro-doses using insulin-sized needles. The most precise way to optimize testosterone for men and women.

Topical creams

Compounded testosterone, estradiol, or progesterone applied daily. Ideal for those who prefer no needles.

Pellets

Bioidentical hormone pellets placed just under the skin every 3–5 months for steady, hands-off delivery.

Oral & vaginal

Oral micronized progesterone for sleep and uterine protection; vaginal estradiol for genitourinary symptoms.

What to Expect

Your first 6 months on HRT.

  1. Week 1

    Comprehensive lab panel

    Full hormone, metabolic, and cardiometabolic workup. Hormones, thyroid, lipids, insulin, inflammation markers, and more.

  2. Week 2

    Provider consultation

    Review labs in detail with your nurse practitioner. Build your personalized protocol — including dose, route, and any adjunct therapies.

  3. Weeks 2–4

    Start therapy

    Most patients notice the first energy and sleep changes within 2–3 weeks. Libido and mood typically shift between weeks 3–6.

  4. Week 8

    Follow-up labs & symptom review

    We check that levels are landing in the optimal range and fine-tune the dose. Subtle adjustments are normal.

  5. Months 3–6

    Body composition & long-term gains

    Muscle, strength, body fat, skin, hair, mood, and stamina continue improving over months 3–6 — accelerated by training and nutrition.
