Aromatase inhibitor for estrogen management
Pricing varies by protocol
Anastrozole is an aromatase inhibitor that prevents excess testosterone from converting to estrogen. When testosterone levels rise during TRT, some of it naturally converts to estradiol — anastrozole keeps that conversion in check.

Start Your EvaluationAnastrozole at RenewRx starts at $85/month. That includes your provider consultation, protocol design, and lab monitoring every 90 days — there is no separate membership fee stacked on top. Final pricing depends on the dose and protocol your clinician prescribes after reviewing your bloodwork.
RenewRx dispenses compounded anastrozole from a licensed 503A pharmacy. Compounded medications are prepared for an individual patient and are not FDA-approved. The FDA-approved branded version is Arimidex. This use is also off-label, meaning it's prescribed at your clinician's discretion outside the approved indication. We'd rather tell you that plainly than let you assume otherwise — your provider will walk you through what it means before you start.
A low-dose oral tablet, usually taken a few times per week rather than daily. It blocks the aromatase enzyme, which converts testosterone into estrogen.
Estrogen levels typically respond within one to two weeks. Your provider confirms with bloodwork before adjusting — this is a medication where guessing is genuinely dangerous.
Over-suppressing estrogen is the real risk. Men need estrogen: too little causes joint pain, low libido, fatigue, mood problems, and long-term bone density loss. This is exactly why anastrozole should never be prescribed without labs.
Yes. Every RenewRx protocol begins with a lab panel reviewed by a licensed provider before anything is prescribed. We won't write a prescription off a questionnaire alone. Labs are rechecked every 90 days so your dose is adjusted to how you're actually responding — not to how you're expected to respond.
Most men on well-managed TRT do not. Anastrozole is for men whose bloodwork shows genuinely elevated estrogen alongside symptoms — not a default add-on. Any clinic that hands it out automatically with every TRT prescription is not reading your labs.
Most of the benefit fades once you stop, because these therapies manage a condition rather than cure it. That said, the goal isn't to keep you on medication forever — your provider will talk with you about duration, tapering, and what an exit looks like. If a clinic never raises that conversation, ask why.
No contract, and no lock-in. Our protocols are structured as three-month programs because that's the window where the physiology actually shows up — hormone and peptide therapy needs time, plus at least one lab recheck, before anyone can honestly say whether it's working. You're committing to giving the protocol a fair trial, not to a contractual obligation.
