503A/503B Compounded BHRT vs. Commercial FDA-Approved Bioidentical Hormones: Price Arbitrage, Testosterone Dosing for Women & Pharmacy Markups
“Bioidentical” does not mean compounded. FDA-approved estradiol patches, gels and oral micronized progesterone are bioidentical, tested for consistent dosing, and usually cost $15–$45 a month through insurance or $25–$85 with a discount card. Compounded creams and troches typically cost $65–$160 a month, are rarely covered, and are not FDA-approved.
Over a year, that is roughly $180–$1,020 for approved generics versus $780–$1,920 for compounded hormones. Compounding still has a role — for allergies to inactive ingredients, unavailable doses, and testosterone for women, which has no FDA-approved US product.

01Bioidentical, compounded and FDA-approved are three different things
Marketing often blurs these words. Separating them makes the decision much easier.
- Bioidentical
- A hormone with the same chemical structure as the one your body makes: estradiol, progesterone, testosterone. It describes the molecule, not how it is made or regulated.
- FDA-approved
- A manufactured product reviewed by the FDA for safety, effectiveness, dose consistency and manufacturing quality, with a standard label.
- Compounded
- A preparation mixed by a pharmacy for an individual prescription or, at outsourcing facilities, in larger batches. Not FDA-approved, even when it contains bioidentical hormones.
FDA-approved bioidentical options you can get today
- Estradiol: patches (generics of Climara, Vivelle-Dot, Minivelle and others), gels (Estrogel, Divigel and generics), a spray (Evamist) and oral tablets.
- Progesterone: oral micronized progesterone (generic Prometrium), the FDA-approved bioidentical progestogen for endometrial protection.
- Combination: an oral estradiol plus progesterone capsule (Bijuva).
- Vaginal: estradiol cream, tablets, inserts and ring, plus prasterone (DHEA) vaginal inserts.
Common compounded formulas
Bi-est or tri-est creams (mixtures of estriol with estradiol and sometimes estrone), progesterone creams or troches, testosterone creams, and pellets. Estriol is not in any FDA-approved US product, so formulas containing it are always compounded.
A 2020 report from the National Academies of Sciences, Engineering, and Medicine found insufficient evidence to support the safety and effectiveness of most compounded bioidentical hormone preparations and recommended limiting their use to patients who cannot use an FDA-approved product. ACOG and The Menopause Society likewise recommend FDA-approved hormone therapy for most patients.

03503A vs 503B compounding: what the numbers mean
The numbers refer to sections of the Federal Food, Drug, and Cosmetic Act that define two kinds of compounding.
503A compounding pharmacies
Traditional compounding pharmacies prepare medications for individual patients based on a prescription. They are overseen mainly by state boards of pharmacy and must follow United States Pharmacopeia standards for compounding, but they are not required to follow the full current good manufacturing practice (cGMP) rules that drug makers follow. Most compounded creams and troches for menopause come from 503A pharmacies.
503B outsourcing facilities
Outsourcing facilities register with the FDA, follow cGMP requirements, are subject to FDA inspection, and can compound in larger batches without patient-specific prescriptions for supply to clinics. Many hormone pellets come from 503B facilities. Being 503B means stronger manufacturing oversight, but the products are still not FDA-approved: no clinical trials were required to show they work or are safe at the doses used.
What to ask your pharmacy
- Is it a 503A pharmacy or a 503B outsourcing facility?
- Is it accredited (for example, by the Pharmacy Compounding Accreditation Board)?
- Does it test batches for potency and, for sterile products, sterility? Can it share a certificate of analysis?
- What base is the cream made in, and how should it be applied for consistent absorption?
For the pellet-specific version of this question, see pellets vs patches.
04Testosterone dosing for women: the case where compounding is common
Testosterone is where compounded and approved routes overlap most, because there is no FDA-approved testosterone product for women in the US. Testosterone is a Schedule III controlled substance, so prescribing requires a DEA-registered clinician and, for electronic prescriptions, certified e-prescribing software.
What the evidence supports
The 2019 Global Consensus Position Statement on testosterone for women, endorsed by major menopause societies, supports testosterone for postmenopausal women with hypoactive sexual desire disorder — low desire that causes distress — after other causes are addressed. It does not support testosterone for energy, mood, bone or muscle as a primary indication, citing insufficient evidence.
How it is usually dosed
- Approved male product, small dose: a fraction (roughly one-tenth) of a typical male daily testosterone gel dose, applied to the skin. Using an approved product off-label gives known manufacturing quality, but measuring tiny doses from a male pump or tube takes care.
- Compounded cream: a pharmacy prepares a female-strength cream so a measured daily amount gives the intended dose. More convenient, but not FDA-approved and potency can vary between batches.
- Pellets: not recommended by the consensus statement, because doses can produce levels well above the female range and cannot be adjusted.
Monitoring
Check total testosterone (84403) at baseline and about three to six weeks after starting, aiming to keep levels within the premenopausal female range, then periodically. Reassess at six months; if there is no meaningful benefit, the consensus advises stopping. Watch for acne, hair growth and scalp hair thinning.
Cost is modest either way: a compounded female testosterone cream commonly runs $30–$70 a month, and a male gel used at a small dose can last many months. Our menopause longevity protocol covers testosterone in the context of a full plan.
05Switching from compounded to FDA-approved hormones
If you are on a compounded cream or troche and want to move to an approved product — to save money, use your insurance or get more predictable dosing — the switch is usually straightforward. Plan it with your prescriber rather than stopping abruptly.
- Step 1 — Gather your details. Bring the exact formula, strength and daily amount from your pharmacy label, how long you have used it, and how your symptoms are controlled. Note any bleeding.
- Step 2 — Pick an approved equivalent. Your clinician will choose a starting estradiol patch or gel dose based on your symptoms rather than trying to convert a cream milligram for milligram, because cream absorption varies. Common patch starting doses run 0.025–0.05 mg a day.
- Step 3 — Replace progesterone cream with oral micronized progesterone if you have a uterus, for example nightly or in a cyclic schedule your clinician sets. This is the most important safety step.
- Step 4 — Reassess in 6–12 weeks. Adjust the dose up or down in standard steps based on symptoms. Routine estradiol blood levels are not usually needed when symptoms are controlled.
- Step 5 — Decide about testosterone separately. If your compounded formula included testosterone, discuss whether you still need it and, if so, a monitored transdermal dose.
What the switch typically saves
Moving from a $110-a-month compounded combination to generic estradiol and progesterone at $25 a month in copays saves about $1,000 a year, or $3,000 over three years. If your deductible applies to prescriptions, a discount card may cost less than insurance until you meet it.
Some people notice a short adjustment period of a few weeks — breast tenderness, spotting or changes in sleep — while the dose settles. Unexpected or persistent bleeding needs evaluation. If you are moving from pellets instead of creams, the timing is different; see pellets vs patches.
07Who should choose which
FDA-approved bioidentical hormones fit most people who…
- Want estradiol and progesterone identical to their own hormones with tested, consistent dosing.
- Have insurance pharmacy coverage, or want the lowest cash price with a discount card.
- Have a uterus and need reliable endometrial protection.
- Want a dose that can be adjusted in standard steps.
Compounding may be reasonable when…
- You are allergic to an inactive ingredient (an adhesive, peanut oil in some progesterone capsules, or a dye) and no approved alternative works.
- You need a dose or form that no approved product offers, and your clinician documents why.
- You and your clinician choose testosterone and prefer a female-strength cream over a fraction of a male gel, with blood-level monitoring.
Be cautious when…
- Compounded hormones are presented as “safer” or “more natural” than approved bioidentical products. The molecules can be the same; the testing is not.
- The plan relies on saliva or urine levels to set doses.
- A clinic sells the compounded product itself and does not offer a prescription you can fill elsewhere.

FAQFrequently asked questions
Are bioidentical hormones the same as compounded hormones?
No. Bioidentical describes the molecule: estradiol, progesterone and testosterone identical to what your body makes. Many bioidentical hormones are FDA-approved, including estradiol patches and gels and oral micronized progesterone. Compounded hormones are mixed by a pharmacy and are not FDA-approved, even when the hormone inside is bioidentical. You can get bioidentical hormone therapy without compounding.
Why are compounded hormones more expensive?
Compounded preparations are made in small batches, are rarely covered by insurance, and are sometimes sold through clinics with a markup. Typical prices run $65–$160 a month, compared with $15–$45 in copays for approved generics through insurance or $25–$85 with a discount card. Ask for the prescription so you can price it at more than one pharmacy.
Is there an FDA-approved testosterone for women?
Not in the US. Testosterone prescribed to women is off-label, either a small fraction of an approved male gel dose or a compounded female-strength cream. It is a Schedule III controlled substance. Evidence supports it mainly for distressing low sexual desire after menopause, dosed to keep blood levels in the female range, with testing at baseline and a few weeks after starting.
What is the difference between a 503A and a 503B pharmacy?
A 503A pharmacy compounds medications for individual patients under state board oversight and USP standards. A 503B outsourcing facility registers with the FDA, follows manufacturing-grade cGMP rules, is inspected by the FDA and can make larger batches for clinics. Neither makes the product FDA-approved; 503B means stronger manufacturing oversight, not proof that the formula is safe and effective.
When does compounded BHRT make sense?
Compounding is reasonable when you cannot use an approved product, for example due to an allergy to an inactive ingredient or a need for a dose no approved product offers, and for testosterone, which has no approved female product. Ask your clinician to document the reason, name the pharmacy, and explain how dose and uterine protection will be monitored.
