TRT + AI vs TRT Alone

Adding anastrozole to TRT lowers estradiol but is over-prescribed historically. Modern practice prefers TRT alone with careful dosing and cadence, reserving aromatase inhibitors for biomarker-confirmed symptomatic hyperestrogenemia.

Choose TRT + aromatase inhibitor

TRT + AI is appropriate only when biomarker-confirmed symptomatic hyperestrogenemia persists despite cadence and dose optimization.

Choose TRT alone

TRT alone is the modern default. Most candidates do not require an aromatase inhibitor.

Explore pathway

Educational. Final pathway selection is provider-reviewed via synchronous video consultation against your biomarkers, history, and goals.

Frequently asked

Is anastrozole always needed on TRT?

No — most candidates do not require it.

What is the risk of crushing estradiol?

Bone, lipid, mood, and libido suffer when estradiol is suppressed too low.
