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.
Learn moreBIEST 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.

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.
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.
If you have a uterus, yes. Estrogen thickens the uterine lining, and progesterone protects it. After hysterectomy, estrogen alone is safe.
Not necessarily. Both work. BIEST appeals to patients seeking a lower dose, a gentler profile, or a compounded approach.
