🌸 Custom HRT, Built Around the Patient

When commercial products don't fit — a strength that isn't available, a combination that isn't manufactured, or a sensitivity to a dye or filler — compounding lets you prescribe exactly what your patient needs. Mixwell compounds each preparation individually to your specifications.

🧬 Commonly Compounded Hormones for Women

🌷 Estradiol (E2)

The primary and most active estrogen prescribed in HRT.

🌸 Estriol (E3)

Often combined with estradiol as Bi-Est in prescriber-selected ratios.

🌙 Progesterone

Frequently prescribed alongside estrogen for balance.

⚡ Testosterone

Prescribed at low doses for some women per clinical evaluation.

🌱 DHEA

A hormone precursor included in some physician-directed protocols.

➕ Combinations

Multiple hormones in a single elegant preparation as prescribed.

💧 Three Routes — Transdermal Is a Frequent Preference

Compounded women's HRT is generally available in oral, transdermal, and vaginal preparations. The transdermal route is a frequent prescriber preference because estrogens are fat-soluble and absorb well through the skin, while the route bypasses first-pass hepatic metabolism.

🧴

Transdermal

★ Frequent preference

Creams & gels in permeation-enhancing bases; bypasses first-pass liver metabolism.

💊

Oral

Capsules & troches; a familiar route subject to first-pass metabolism.

🌷

Vaginal

Creams & inserts for localized symptoms in mucoadhesive bases.

🧪 Advanced PCCA Bases — Matched to the Route

The base determines how well hormones are delivered and how stable and elegant the finished preparation is. Mixwell matches each route to a purpose-built PCCA base.

💎 Route-Specific Base Selection

🧴 Transdermal
Lipoderm®

PCCA's flagship permeation-enhancing transdermal base — widely used and studied for delivering hormones through the skin, with an elegant feel.

🧴 Transdermal · Anhydrous
PermE8™

Anhydrous permeation-enhancing gel (water activity below 0.6) supporting extended default BUDs and multi-active formulations.

🌷 Vaginal / Mucosal
MucoLox™

A mucoadhesive base designed to adhere to mucosal tissue, supporting localized vaginal preparations as prescribed.

🌿 Elegant Topical
WO6™

An anhydrous, emollient base with a smooth, creamy finish for oxidation-prone actives — topical use.

❓ What is a permeation-enhancing base?

A permeation-enhancing base is a specialized transdermal vehicle designed to help active ingredients cross the skin barrier into systemic circulation. For transdermal HRT, these bases support consistent delivery of fat-soluble hormones through the skin while providing a stable, cosmetically elegant finished preparation.

📚 The Evidence Base

Clinical context for prescribers:

A 2025 in vitro percutaneous-absorption study published in Pharmaceutics evaluated compounded estradiol and Bi-Est formulations in proprietary permeation-enhancing bases versus a commercial estradiol transdermal gel, examining how base selection influences transdermal estrogen delivery. Foundational literature describes the estrogens, progesterone, testosterone, and DHEA commonly used in compounded hormone therapy and confirms that these preparations are generally available in oral, transdermal, and vaginal forms.

Compounded HRT is prescribed and monitored by the treating clinician based on individual evaluation, symptoms, and goals. The prescriber determines the appropriate hormones, route, and formulation for each patient.
⚠️ For licensed prescribers. Compounded hormone preparations are not FDA-approved drug products and are prepared pursuant to a valid prescription. Hormone therapy carries individual risks and benefits to be assessed by the prescriber. These formulations are not a substitute for clinical judgment. Mixwell is a non-sterile compounding pharmacy.
