About Anastrozole
Compounded anastrozole is an aromatase inhibitor prescribed primarily to men on testosterone replacement therapy (TRT) to control estradiol elevation and prevent estrogen-related side effects (gynecomastia, water retention, mood changes, fatigue). It's also used off-label in fertility protocols and as adjunctive therapy in certain oncology settings. Commercial anastrozole tablets (Arimidex, generic) are dosed at 1 mg — typically too much for men on TRT, who need fractional doses (0.125–0.5 mg, two to three times weekly). Compounding pharmacies prepare anastrozole in custom sub-milligram strengths, sublingual troches, and transdermal creams to match precise TRT titration protocols.
Who uses compounded anastrozole
The largest clinical use by volume is men on TRT whose estradiol has risen above their target range — typically 20–40 pg/mL on most protocols, though target ranges vary by clinician. Symptoms of elevated estradiol on TRT include gynecomastia (breast tissue development), water retention, moodiness, headaches, and loss of libido.
Anastrozole is also used in ovulation induction protocols for women with PCOS or unexplained infertility (typically 1 mg daily × 5 days starting cycle day 3), and as adjuvant therapy for hormone-receptor-positive breast cancer in postmenopausal women (standard 1 mg daily). The oncology and fertility uses are generally filled with commercial 1 mg tablets; compounding is driven by TRT microdosing needs.
Why compound anastrozole instead of splitting commercial tablets
Commercial anastrozole tablets are 1 mg — but men on TRT typically need 0.125–0.5 mg, two or three times per week, based on estradiol lab values. Splitting a 1 mg tablet into quarters gives inconsistent doses because the active ingredient isn't necessarily distributed evenly through the tablet.
Compounded anastrozole capsules at exact strengths (0.125 mg, 0.25 mg, 0.5 mg) deliver consistent, predictable doses that match protocol titration. Sublingual troches and transdermal creams offer alternative delivery for patients who don't tolerate oral anastrozole well, or for those titrating very small doses where absorption variability matters.
Typical TRT anastrozole dosing protocols
Most TRT protocols use anastrozole only as needed — starting with labs at 4–6 weeks after TRT initiation, then dosing if estradiol has risen above the target range. Common starting protocols: 0.25 mg twice weekly, or 0.5 mg once weekly, with follow-up labs at 4 weeks to adjust.
Some clinicians prefer a more conservative approach — no anastrozole unless symptoms of estrogen excess appear (not just elevated labs). Estradiol control is individualized; your prescriber sets the protocol. Monitoring typically includes estradiol (sensitive assay), testosterone, and SHBG.
Typical compounded anastrozole pricing
Compounded anastrozole capsules typically run $25–$60 for a 30- or 90-day supply at TRT-typical sub-mg strengths. Sublingual troches are $30–$75 per 30-day supply. Transdermal creams are $40–$90.
Commercial generic anastrozole 1 mg tablets are much cheaper per pill — but the whole tablet is wrong for TRT dosing. If you're paying out of pocket and your protocol uses 0.5 mg or less per dose, the precision of compounding typically justifies the cost difference. Comparing quotes before filling saves 20–40% on compounded preparations.
Key Questions Before You Request Quotes
Can I get Anastrozole compounded?
Possibly. A licensed prescriber has to decide whether Anastrozole is appropriate, and a licensed compounding pharmacy has to confirm it can legally prepare the requested strength, form, and quantity.
Is a prescription needed?
Yes. Patient-specific 503A compounding is based on a valid prescription order or prescriber notation for an identified patient.
What affects price?
Strength, dosage form, quantity, ingredient sourcing, sterile versus non-sterile preparation, shipping requirements, and each pharmacy's workflow can all change the final quote.
How fast can I get quotes?
For routable requests, Compounding Finder typically returns quote options by email within 1-2 business days after you submit the request details.
What happens after I submit?
We review the request, route it to eligible licensed pharmacies, collect available options, and email you the quoted choices. You decide whether to move forward with a pharmacy.
Source notes: FDA explains that compounded drugs are not FDA-approved finished products and describes 503A compounding around patient-specific prescriptions. See Compounding and the FDA and Section 503A.

Frequently Asked Questions
Why is compounded anastrozole preferred over generic Arimidex for TRT?
Commercial anastrozole comes only in 1 mg tablets, which is too much for most men on TRT — typical doses are 0.125–0.5 mg, two or three times weekly. Splitting 1 mg tablets into quarters gives inconsistent doses because the active ingredient isn't guaranteed to distribute evenly. Compounded sub-mg capsules (0.125, 0.25, 0.5 mg) deliver precise, consistent doses that match TRT titration protocols.
What dose of anastrozole do men on TRT typically take?
Most TRT protocols use 0.125–0.5 mg, two or three times per week, adjusted based on estradiol lab values and symptoms. Common starting protocols are 0.25 mg twice weekly or 0.5 mg once weekly, with follow-up labs at 4 weeks to adjust. Some clinicians prefer no anastrozole unless symptoms of estrogen excess appear. Your prescriber sets the protocol based on your individual labs and response.
Is anastrozole safe long-term for men on TRT?
At sub-mg TRT doses, long-term use is generally well-tolerated but not risk-free. Potential concerns include excessive estradiol suppression (which causes its own problems: joint pain, dry skin, mood changes, accelerated bone density loss), elevated LDL cholesterol, and reduced cardiovascular benefit of a normal estradiol. Many TRT clinicians now prefer a conservative 'treat symptoms, not numbers' approach to minimize unnecessary anastrozole exposure.
How much does compounded anastrozole cost?
Compounded anastrozole capsules typically run $25–$60 for a 30- or 90-day supply at TRT sub-mg strengths. Sublingual troches are $30–$75 per 30-day supply. Transdermal creams are $40–$90. Commercial generic 1 mg tablets are much cheaper per pill but aren't dosed correctly for TRT — compounding typically pays for itself in dosing precision.
