The Hormone Symphony Model views estrogen, progesterone, and testosterone as interacting instruments rather than independent supplements. A change to one can alter the behavior or conversion of the others. For example, aromatase can convert testosterone into estrogens, and abdominal adiposity may influence which pathway becomes dominant. The clinician therefore assesses symptoms, metabolic state, body composition, conventional labs, and—when useful—pathway-oriented testing before choosing a formulation and delivery method. Bioidentical progesterone is distinguished from synthetic progestins, and estrogen is not assumed to be replaceable by testosterone conversion alone. The patient's experience matters because patches, injections, troches, pellets, and other forms can produce different practical responses. Monitoring continues after treatment begins, with the complete regimen rebalanced when pain, mood, cognition, fat distribution, or laboratory patterns change.
Origin
Extracted from Habits & Hustle, where Dr. Tyna Moore compared balanced hormone care to a symphony requiring all of its instruments.
Core principles
- 01Hormones operate as an interacting system.
- 02Bioidentical progesterone is not interchangeable with synthetic progestins.
- 03Testosterone conversion depends partly on aromatase activity and fat distribution.
- 04Symptoms, pathways, and laboratory findings should be interpreted together.
- 05Delivery method and dose can materially change patient response.
How to run it
- 1
Map the hormonal system
Review symptoms, cycle or menopausal status, body composition, metabolic health, medications, and relevant risks. Establish which hormones and pathways need evaluation.
Pro tip Include changes in pain, cognition, sleep, mood, and fat distribution.
Watch out A single laboratory value cannot describe the whole hormonal system.
- 2
Test strategically
Use appropriate blood testing and, when clinically useful, pathway-oriented tests to understand levels and conversions. Interpret results in conjunction with symptoms.
Pro tip Repeat testing after meaningful dose or delivery changes.
Watch out Testing without clinical context can encourage treatment of numbers rather than people.
- 3
Balance the instruments
Consider estrogen, real bioidentical progesterone, and testosterone together. Give each prescribed component a specific role in the overall plan.
Pro tip Explain why each hormone is included or excluded.
Watch out Do not assume synthetic progestins behave like progesterone.
- 4
Account for conversion
Evaluate whether testosterone may be aromatizing in an unfavorable way, particularly when abdominal adiposity or rising estrone is present. Adjust the system rather than simply increasing one hormone.
Pro tip Watch trends in body shape, pain, and symptoms alongside laboratory changes.
Watch out Testosterone cannot always be relied upon to provide favorable estrogen support.
- 5
Match delivery to response
Choose among appropriate patches, injections, compounded preparations, or other delivery forms based on clinical needs, access, cost, and patient response.
Pro tip A conventional pharmacy may provide affordable bioidentical options.
Watch out More expensive or compounded delivery is not automatically more effective.
- 6
Retune over time
Monitor outcomes and adjust the complete regimen as physiology changes. Reconsider dose, ratios, and delivery method when new symptoms emerge.
Pro tip Make controlled changes so the source of improvement or deterioration remains visible.
Watch out Changing multiple hormones simultaneously can make the response impossible to interpret.
In the wild
Moore described initially becoming leaner on testosterone, then gradually developing a more apple-shaped midsection and worsening pain. Testing showed very high estrone, leading her to question whether testosterone was converting unfavorably rather than supplying the estrogen effect she wanted.
→ Testing and symptom patterns prompted a reassessment of relying on testosterone alone.
Moore reported obtaining little benefit from previous estrogen delivery approaches until she used a patch. The patch produced a markedly different subjective response, including calm and reduced pain, illustrating why delivery cannot be treated as interchangeable.
→ An individualized delivery method produced the desired therapeutic response.
Common mistakes
Playing only one instrument
Using testosterone, estrogen, or progesterone alone without examining the rest of the system can create imbalance or miss an important need.
Confusing progestins with progesterone
Synthetic progestins do not have the same cellular effects as real bioidentical progesterone and should not be treated as identical.
Ignoring aromatization
Assuming testosterone will always convert into a favorable estrogen profile overlooks aromatase activity, abdominal fat, and estrone.
Is it for you?
Best for
Qualified clinicians and patients evaluating individualized bioidentical hormone replacement during perimenopause and menopause.
Not ideal for
It is not suitable for self-directed hormone stacking or for replacing contraindication screening with symptom-based experimentation.
From the transcript
“And I think all of I think of all of these as like a symphony. We need all the instruments, right?”
“But relying solely on testosterone, I I think I don't think is it.”
“So we use progesterone, natural, real bioidentical progesterone, to offset any issues with estrogen.”
