Bi-Est 50:50 Cream

Bioidentical estrogen cream (50% estriol + 50% estradiol) applied to the skin daily. In the ELITE trial (Hodis et al., NEJM 2016), women who started estrogen within 6 years of menopause had measurably less wall thickening in their carotid arteries over 5 years than women on placebo.

Why Patients Choose

Delivered through the skin, not swallowed

bypasses first-pass liver metabolism (lower clotting-factor activation than oral estrogen in published comparisons)

Bioidentical molecules: same estradiol and estriol your body made before menopause

50:50 ratio means roughly half the dose is estriol, the weaker estrogen

In the ELITE trial, women starting within 6 years of menopause showed slowed carotid artery thickening vs.

placebo over 5 years

Compounded to the strength your physician prescribes

not a one-size-fits-all retail dose

How

Estradiol and estriol are the same estrogen molecules your ovaries made before menopause.

They dock onto estrogen receptors (ER-alpha and ER-beta) in tissues like brain, bone, vagina, and blood vessels. When you go through the skin instead of the gut, the estrogen reaches your bloodstream without first passing through the liver — which is why transdermal estrogen has not shown the same clotting risk that oral estrogen has in observational studies.

Frequently Asked Questions

The WHI enrolled women on average 12+ years past menopause, using oral conjugated equine estrogen plus a synthetic progestin. ELITE and later analyses showed the risk profile is different for women who start within 6 years of menopause, using bioidentical hormones, transdermally. That's the population this is prescribed for.

It's a legal prescription filled by a licensed 503A compounding pharmacy in the U.S. The physician who reviews your intake is licensed in your state. Not gray market. Not research chemical.

If you still have your uterus, yes — estrogen alone raises endometrial cancer risk. Your physician will prescribe progesterone with it. If you've had a hysterectomy, estrogen alone is appropriate.
