BIEST — short for "bi-estrogen" — is a compounded blend of two estrogens, most often estriol and estradiol, prepared for each individual patient by a U.S. 503A compounding pharmacy. Because it's compounded per prescription, a licensed provider and the pharmacy tailor the estriol-to-estradiol ratio and dose to you rather than dispensing one fixed strength off a shelf.

It's used for menopausal symptom relief and delivered as a topical cream applied to the skin on a schedule your provider sets. Like other estrogen therapies, BIEST is generally paired with progesterone if you still have a uterus, to protect the uterine lining. Your provider reviews your personal and family history, adjusts the ratio and dose to your response, and follows up over time.

Exact strengths vary by prescription; your provider decides whether BIEST is appropriate — and which ratio fits your symptoms — during your online visit.

Understanding the cause

Why are menopause symptoms happening in the first place?

Around perimenopause and menopause, the ovaries produce less estrogen — and that decline is behind the symptoms women notice most: hot flashes, night sweats, and vaginal dryness. Estrogen influences temperature regulation, tissue moisture, sleep, and mood, so when it falls, comfort and quality of life often take the hit. Estrogen therapy replaces some of what's declined, and BIEST does it with a two-estrogen blend compounded to you.

Symptoms often persist

Some menopause symptoms, like vaginal dryness, generally don't resolve on their own over time — untreated, they tend to persist or progress rather than fade.

It's treatable and individualized

If hot flashes, night sweats, or dryness are interfering with daily comfort, that alone is reason enough to talk to a provider — and a compounded blend lets the estriol-to-estradiol ratio be tailored to your symptoms.

Know the difference

OTC menopause supplement vs. single-estrogen Rx vs. compounded BIEST — what's the difference?

The short answer: over-the-counter supplements offer plant-based support with variable evidence, a single-estrogen prescription replaces estradiol at fixed strengths, and compounded BIEST blends two estrogens at a ratio and dose a provider tailors to you.

Many women try supplements first and find the effect inconsistent. A provider-prescribed estrogen is the next step up: BIEST offers the same at-home cream routine, but with a licensed provider in the loop and a blend built for your symptoms instead of a fixed off-the-shelf product.

How it works

How does a compounded estrogen blend work?

It replaces some of the estrogen that declines at menopause, using a two-estrogen blend compounded to your ratio and dose, then adjusted by your provider over time rather than sold in one fixed strength.

I

Estrogen declines

Around menopause, estrogen falls — the drop behind hot flashes, night sweats, and vaginal dryness.

II

BIEST is compounded

A 503A pharmacy blends estriol and estradiol to your provider's prescription and prepares your cream at the ratio chosen for you.

III

Balance & monitor

Your provider fine-tunes the ratio and dose and, if you have a uterus, pairs it with progesterone — with follow-up over time.

Who it's for

Who is BIEST for?

It's for women in perimenopause or menopause who want an estrogen therapy compounded to their individual needs and prefer a topical cream.

Bothersome menopause symptoms

Hot flashes, night sweats, or vaginal dryness that are interfering with daily comfort or sleep.

You want an individualized blend

You'd rather have the estriol-to-estradiol ratio and dose tailored to you than take one fixed off-the-shelf strength.

You prefer a topical cream

A needle-free, at-home routine applied to the skin on a schedule your provider sets — not as-needed.

You want provider guidance

You want a licensed provider to review your history, adjust your ratio and dose, and follow up over time.

When it's not the right fit

If you still have a uterus, estrogen is generally paired with progesterone to protect the uterine lining — estrogen alone may be appropriate only after a hysterectomy. And if you have a history of estrogen-sensitive cancer, blood clots, unexplained vaginal bleeding, or are or could be pregnant, those need evaluation before starting any estrogen — mention them in your visit.

Safety & side effects

⚠ Estrogen needs uterine protection

If you still have a uterus, BIEST is generally paired with progesterone to protect the uterine lining. BIEST is a compounded preparation and is not FDA-approved; it's provider-guided and monitored, and isn't right for everyone — tell your provider your full personal and family history before starting.

As an estrogen therapy, possible side effects your provider watches for include:

  • Breast tenderness
  • Bloating or nausea
  • Headache
  • Spotting or breakthrough bleeding
  • Skin irritation at the application site

Tell your provider about all conditions and medications, and any history of estrogen-sensitive cancer or blood clots. Seek care for chest pain, shortness of breath, leg swelling, or sudden severe headache. Your provider reviews your history, adjusts your ratio and dose, and follows up over time.

BIEST / HRT FAQ

What is BIEST and am I a candidate?

BIEST — "bi-estrogen" — is a compounded blend of two estrogens, typically estriol and estradiol, used for menopausal symptom relief. You may be a candidate if you're in perimenopause or menopause with bothersome symptoms and prefer an individualized, topical estrogen. A licensed provider reviews your symptoms and history to decide whether it's appropriate for you.

How is BIEST different from estradiol alone?

Estradiol is a single estrogen — the primary estrogen used in menopausal hormone therapy. BIEST is a compounded blend of two estrogens (usually estriol and estradiol), with the ratio tailored to you by your provider and a 503A pharmacy. Your provider helps decide which approach fits your symptoms and preferences.

Do I need progesterone with BIEST?

If you still have a uterus, BIEST — like other estrogen therapies — is generally paired with progesterone to protect the uterine lining. If you've had a hysterectomy, estrogen alone may be appropriate. Your provider decides the right combination for you.

Is BIEST FDA-approved?

BIEST is a compounded preparation, made for an individual patient by a 503A pharmacy pursuant to a valid prescription — compounded medications are not FDA-approved. It's prescribed and monitored by a licensed provider. Your provider can talk through the differences between compounded and FDA-approved options.

What are the side effects and how is it monitored?

As an estrogen therapy, possible side effects include breast tenderness, bloating, headache, spotting, and skin irritation at the application site. Because hormone therapy carries individual risks and benefits, BIEST is provider-guided and monitored — your provider reviews your history, adjusts your ratio and dose, and follows up over time.

How is it prescribed and shipped?

After your online visit, a licensed provider reviews your information. If BIEST is appropriate, your compounded cream is prepared by a 503A pharmacy and ships discreetly to your door in unmarked packaging, with refills to keep you on schedule. Prescription approval is not guaranteed and is subject to provider review.
