    WHAT IT IS

    Two estrogens,
    one preparation.

    If you have questions about Bi-Est, they are worth raising with your prescriber. Our guide on how to ask your doctor about compounded medication can help you start that conversation.

    Estradiol is the main estrogen the ovaries make before menopause. Estriol is a weaker estrogen that the body makes in larger amounts during pregnancy, and it is not available as a commercially manufactured product in the United States. Bi-Est combines the two, so a prescription for it is prepared by a compounding pharmacy.

    We prepare Bi-Est as an olive oil base topical. It is one of the forms of bioidentical hormone therapy we compound, and it is often prescribed alongside compounded progesterone. If your estradiol patch has been hard to fill, our page on estradiol patch alternatives explains the preparations a prescriber can order instead.

    Whether Bi-Est is right for you, at what ratio and strength and how often, are decisions for you and your prescriber.

    worth knowing.

    What is Bi-Est?

    Bi-Est is a compounded combination of two estrogens, estradiol and estriol, in the ratio and strength your prescriber specifies. There is no commercially manufactured Bi-Est product in the United States.

    Does your Bi-Est contain estrone?

    No. Our Bi-Est contains estradiol and estriol only.

    Who decides the ratio and strength?

    Your prescriber. The ratio of estradiol to estriol and the strength are written on your prescription, and we prepare exactly what is written. We do not prescribe. If your prescriber changes either one, send us the new prescription and we will prepare it to match.

    What form do you prepare Bi-Est in?

    An olive oil base topical, compounded to order for you. A pharmacist reviews every formulation before it is made.

    Is Bi-Est FDA approved?

    No. Because there is no commercially manufactured Bi-Est product, it is prepared by a compounding pharmacy for the patient named on the prescription.

    Can you ship to my state, and how long does it take?

    We are licensed in all 50 states and the District of Columbia. We have a 48-hour compounding time on most preparations. Shipping time is additional and varies by destination. A member of our team confirms the price with you before anything is processed, made, or shipped.
