KAMURAEstablished uses for specific hormone products
Menopausal symptoms; evidence depends on the hormone, route and indication.
Bioidentical hormone creams (BHRT)
The hormones themselves are real medicine with real evidence. What is not established is that a pharmacy-mixed, individually dosed version is better than the regulated product — and it is harder to dose accurately.
Custom blends are not proven equivalent or superior
Check the exact ingredients, delivery route and preparation. An ingredient study does not establish the performance of every blend.

What is it?
A pharmacy mixes hormones — usually estradiol (E2), estriol (E3), progesterone or testosterone — into a cream, gel or pessary at a strength written for one person. "Bioidentical" means the molecule is structurally identical to the hormone your body makes. That is also true of several regulated, manufactured products, so the word describes the molecule, not the compounding.
Why this formulation?
Legitimate reasons exist: a strength that is not manufactured, an allergy to an excipient in the commercial product, a combination (such as estriol with estradiol) that is not sold ready-made, or a delivery form a person tolerates better. Less legitimate is compounding purely so a clinic can market a bespoke formula.
What can the research tell us?
Menopausal hormone therapy has a large, genuine evidence base for hot flushes, night sweats, vaginal symptoms and bone protection. That evidence comes almost entirely from standardised, manufactured products. Compounded versions have been studied far less; major menopause and endocrine societies have repeatedly noted that compounded hormones are not proven superior, have formulation and dose-consistency concerns that require checking with the pharmacy. The hormone is evidenced; the compounding is not.
Read the supporting sources ↓What to discuss about alternatives
Ask whether a regulated, manufactured hormone product would do the same job. For most people it would, with better dose consistency and clearer safety data. Compounding should be the answer to a specific problem with the commercial option — not the default starting point.
Contexts to discuss with a clinician
- Menopausal symptoms when a manufactured product is unsuitable — for example an allergy to an ingredient in it
- A strength or combination that is genuinely not available commercially
- Vaginal or genitourinary symptoms where a specific local preparation is wanted
Details worth checking
- Absorption through skin varies a lot between people, so the dose applied is not the dose delivered
- Saliva hormone testing is widely marketed alongside these creams and is not considered reliable for guiding dosing
- Estrogen without adequate progesterone protection, in someone with a uterus, raises endometrial risk
- Cream transferring to a partner or child through skin contact
- Claims that compounded hormones are "safer" or "natural" compared with regulated ones — that is marketing, not evidence
