About Triest
Triest (Tri-Est) is a compounded blend of three estrogens — estriol, estradiol, and estrone — used in bioidentical hormone replacement therapy for perimenopause and menopause. It is only available from compounding pharmacies, prepared as creams, capsules, and troches in prescriber-specified ratios.
What is Triest?
Triest is a compounded combination of the three main human estrogens: estriol (E3), estradiol (E2), and estrone (E1). A common historical ratio is 80% estriol, 10% estradiol, and 10% estrone, though the prescriber sets the exact blend. It is closely related to Biest, which omits estrone and combines only estriol and estradiol.
Triest is specific to compounding — there is no FDA-approved Triest product. It reflects an integrative-medicine approach of dosing estrogens in proportions intended to mimic the body's own mix. There is no high-quality evidence that Triest or Biest is safer or more effective than FDA-approved estradiol products; the potential risks of estrogen therapy apply to compounded blends as well.
Triest vs. Biest
Both are compounded multi-estrogen blends. Biest (estriol + estradiol) is now more commonly prescribed than Triest, in part because estrone is a metabolite the body readily produces from estradiol on its own, and some clinicians see no advantage to supplementing it directly.
If your prescription says Bi-Est, Tri-Est, E3/E2, or lists percentage ratios like 80/10/10, a compounding pharmacy can prepare it. Bring the exact wording of your prescription when requesting quotes — the ratio, total strength, and base all affect price.
Available forms and strengths
Compounding pharmacies most often prepare Triest as a transdermal cream or gel dosed in milligrams per pump or per gram. Oral capsules, sublingual troches, and vaginal preparations are also compounded when prescribed.
Progesterone or testosterone is sometimes combined into the same preparation for convenience, which can reduce the number of separate prescriptions you fill.
Typical compounded Triest pricing
Compounded estrogen creams, including Triest and Biest, commonly fall in the same broad range as other compounded hormone creams — roughly $40–$120 per month depending on strength, ratio, base, and quantity dispensed. Insurance frequently does not cover compounded hormones, so most patients pay cash.
Because each pharmacy sets its own pricing, comparing quotes from more than one licensed compounding pharmacy before filling routinely uncovers meaningful savings on a therapy you may refill for years.
Key Questions Before You Request Quotes
Can I get Triest compounded?
Possibly. A licensed prescriber has to decide whether Triest is appropriate, and a licensed compounding pharmacy has to confirm it can legally prepare the requested strength, form, and quantity.
Is a prescription needed?
Yes. Patient-specific 503A compounding is based on a valid prescription order or prescriber notation for an identified patient.
What affects price?
Strength, dosage form, quantity, ingredient sourcing, sterile versus non-sterile preparation, shipping requirements, and each pharmacy's workflow can all change the final quote.
How fast can I get quotes?
For routable requests, Compounding Finder typically returns quote options by email within 1-2 business days after you submit the request details.
What happens after I submit?
We review the request, route it to eligible licensed pharmacies, collect available options, and email you the quoted choices. You decide whether to move forward with a pharmacy.
Source notes: FDA explains that compounded drugs are not FDA-approved finished products and describes 503A compounding around patient-specific prescriptions. See Compounding and the FDA and Section 503A.

Why Compare Triest Prices?
Compounded medication prices vary significantly between pharmacies — sometimes by 300% or more for the exact same drug, strength, and formulation. Factors that affect pricing include the pharmacy’s location, their ingredient sourcing, and compounding volume.
By comparing quotes from multiple licensed pharmacies, you can find the best combination of price, quality, and convenience without spending hours making phone calls.
Frequently Asked Questions
Is Triest FDA-approved?
No. Triest is a compounded preparation and is not FDA-approved. FDA-approved bioidentical estradiol products (tablets, patches, gels, and vaginal preparations) exist, and compounded Triest is generally reserved for patients whose prescriber documents a reason a commercial product does not fit — such as a custom ratio, strength, or excipient sensitivity.
What is the difference between Triest and Biest?
Biest combines two estrogens (estriol and estradiol); Triest adds a third, estrone. Biest is the more commonly prescribed blend today. The choice of blend and ratio is made by your prescriber.
Do I need a prescription for compounded Triest?
Yes. All compounded estrogen therapy requires a valid prescription from a licensed U.S. healthcare provider. A legitimate compounding pharmacy will not dispense Triest without one.
How much does compounded Triest cost?
Most compounded estrogen creams run roughly $40–$120 per month, and Triest is usually priced like other custom hormone creams — the ratio, strength, base, and quantity all matter. Prices differ meaningfully between pharmacies, so comparing quotes before filling is worthwhile for a long-term therapy.
