What is BIEST 50:50 cream?

(50% estriol, 50% estradiol)

BIEST 50:50 balances estriol and estradiol equally, offering more symptom relief than the 20:80 blend for patients with moderate to severe hot flashes or night sweats. Apply topically for gradual, steady absorption.

What's in it

  • BIEST (50:50)Estrogen: eases menopause symptoms

50:50

a balanced estriol-estradiol blend for moderate symptoms

Apply 0.5-1.5 grams daily to clean skin. Your physician titrates based on symptom control and lab work.

Is it right for you?

  • Who it's for

    Women who need a stronger estrogen effect through the skin.

  • What sets it apart

    Half estradiol, half estriol: more estradiol than the 20:80 blend, so it is stronger at the same amount.

  • Worth knowing before you start

    Compounded Bi-Est is not FDA-approved. FDA-approved estradiol patches and gels exist.

Results you can feel

  • Fewer hot flashes

    the most dramatic change from estrogen therapy

  • Better sleep and mood

    as night sweats settle and hormones stabilize

  • Bone protection

    estrogen slows bone loss at menopause

  • Steadier energy

    many patients report clearer, more stable daily rhythms

The science of bioidentical estrogen

A 50:50 blend offers more estradiol activity while retaining estriol's gentler tissue profile. Transdermal delivery reduces first-pass hepatic metabolism.

BIEST conlleva the same safety profile as all estrogen therapy: clot, stroke, and gallbladder risk. Your physician monitors your blood pressure and reviews risk factors at every visit.

Important safety information and common side effects

BIEST is a prescription hormone combination with real benefits and real risks. Common effects include breast tenderness, bloating, nausea, headache, spotting, and injection-site reactions. Estrogen therapy increases risk of blood clots, stroke, gallbladder disease, and, with a uterus, requires progesterone to prevent endometrial cancer. Not prescribed with breast cancer, blood clots, unexplained vaginal bleeding, liver disease, or pregnancy. Smoking raises clot risk. Seek care for chest pain, shortness of breath, leg swelling, severe headache, or vision changes. Tell your physician about every medication.

Frequently asked questions

How do I use BIEST (50:50) Cream?

Applied to the skin, once a day. The starting prescription is 1 mL (4 clicks, 0.75 mg) each time. Your physician sets your own dose and it is printed on your label.

Where do I apply it?

Inner forearm or inner thigh.

What strengths does BIEST (50:50) Cream come in?

The pharmacy carries 7: 0.75 mg/mL, 2.75 mg/mL, 2 mg/mL, 1.25 mg/mL, 1.5 mg/mL, 3 mg/mL, 1 mg/mL. Your physician chooses which one you get.

How much arrives in each shipment?

1 tube at the starting strength, shipped to your door from a licensed US pharmacy.

Should I start with 20:80 or 50:50?

Your physician sets the starting ratio based on symptom severity. Starting with 20:80 allows tolerability assessment; if symptoms persist, your physician may increase to 50:50. Some patients start directly at 50:50 if symptoms are significant.

Is BIEST really bioidentical?

Yes. Estriol and estradiol are both bioidentical, meaning their chemical structure matches what your body made. BIEST is a compounded formula mixing these two in a specific ratio.

Do I need progesterone with BIEST?

If you have a uterus, yes. Estrogen thickens the uterine lining, and progesterone protects it. After hysterectomy, estrogen alone is safe.

Is BIEST better than estradiol alone?

Not necessarily. Both work. BIEST appeals to patients seeking a lower dose, a gentler profile, or a compounded approach.
