What is Bi-Estrogen Cream 2.5mg? 

This topical HRT formulation combines Estradiol and Estriol in a bioidentical cream designed for hormone replacement therapy research and clinical use. Formulated at 2.5mg strength for a 90-day supply, it is ideal for low-dose estrogen studies, initial HRT protocols, and transdermal delivery research under controlled clinical conditions.

Mechanism of Action The bioidentical estrogen compounds bind to estrogen receptors (ERα and ERβ), initiating intracellular signaling that supports hormonal regulation, tissue maintenance, and cellular repair. The low-dose transdermal delivery provides a controlled and consistent systemic absorption profile while minimizing hepatic exposure.

The Science

• Study low-dose estrogen receptor interactions
• Evaluate transdermal absorption at minimal effective concentrations
• Assess hormonal signaling with reduced systemic exposure
• Analyze estrogenic effects on bone density, skin, and mood
• Conduct reproducible low-dose in vitro and clinical studies

Purity & Quality

• ≥99% purity verified via HPLC
• Certificate of Analysis included

Storage: Store at room temperature in a cool, dry place
