EPI-Testosterone (Post-menopausal)

Optimal result: 0 – 5 ng/mg Creat/Day
Doctor's Data

Peer-reviewed sources

This epimer of testosterone is produced in equal amounts with testosterone. It is also a weak competitive antagonist of the androgen receptor making it a weak antiandrogen. Epi-T can inhibit 5-alpha reductase. Measurement of epi-T in urine is used to detect athletic doping since epi-T is unaffected by exogenous testosterone supplementation. Ingestion of alcohol has been shown to increase epi-T levels.

Low levels of epitestosterone may be the result of low precursor levels and/or hormonal contraceptives. Research is limited in the significance of this finding.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
