Product Overview

Arimidex 1 mg by Dragon Pharma

Arimidex 1 mg is an oral anastrozole tablet manufactured by Dragon Pharma and dosed at 1 mg per tablet in a 100-tablet package.

Anastrozole Oral

Arimidex 1 mg contains anastrozole, a non-steroidal aromatase inhibitor. Anastrozole works by blocking the aromatase enzyme, which converts androgens to estrogens. It is a triazole derivative that binds reversibly to the heme prosthetic group of aromatase, providing potent and specific inhibition of estrogen biosynthesis. In clinical practice, anastrozole is FDA-approved for the treatment of hormone receptor-positive breast cancer in postmenopausal women.

In non-medical bodybuilding contexts, Arimidex is commonly referenced as an aromatase inhibitor used to manage estrogenic side effects of anabolic steroid cycles, including gynecomastia, water retention, and elevated blood pressure. Illicit use by bodybuilders typically involves doses of 0.5 mg twice weekly starting from week two of a cycle. A forum analysis of aromatase inhibitor use in steroid users reported a mean anastrozole dose of 0.4 mg over a median of 70 days.

Anastrozole is a prescription medication, and its use for bodybuilding purposes is not approved by the FDA and is considered illegal. Medical supervision is required for any use of this compound, and self-medication carries significant risks including bone mineral density loss, arthralgia, dyslipidemia, and cardiovascular events.

Key Benefits of Arimidex 1 mg

  • Potent and specific aromatase inhibition
  • Half-life of approximately 50 hours supports less frequent dosing
  • FDA-approved for hormone receptor-positive breast cancer
  • Commonly referenced in bodybuilding for estrogen management
  • 1 mg tablet strength for precise dosing
Product Profile

Anastrozole Profile

Anastrozole is a third-generation non-steroidal aromatase inhibitor characterized by potent and specific inhibition of estrogen biosynthesis, a long half-life of approximately 50 hours, and extensive hepatic metabolism.

Non-Steroidal Aromatase Inhibitor

Anastrozole belongs to the class of type II non-steroidal aromatase inhibitors. These agents are triazoles that bind reversibly to the aromatase enzyme, fitting into the substrate binding site so that azole nitrogens interact with the heme prosthetic group. This mechanism provides exquisite potency and specificity against aromatase, the enzyme responsible for converting androgens to estrogens.

The pharmacokinetics of anastrozole are well characterized. Plasma concentrations approach steady-state levels at about 7 days of once-daily dosing, and steady-state plasma levels are approximately 3- to 4-fold higher than levels observed after a single dose. The mean elimination half-life of anastrozole is approximately 50 hours. Anastrozole is 40% bound to plasma proteins in the therapeutic range.

Metabolism of anastrozole occurs by N-dealkylation, hydroxylation, and glucuronidation, with three metabolites identified in human plasma and urine. The major circulating metabolite, triazole, lacks pharmacologic activity. Hepatic metabolism accounts for approximately 85% of anastrozole elimination, while renal elimination accounts for approximately 10% of total clearance.

Defining Characteristic

Potent, Specific Aromatase Inhibition

Anastrozole provides potent and specific inhibition of the aromatase enzyme, with a half-life of approximately 50 hours that supports once-daily dosing in clinical settings.

Arimidex 1 mg vs Other Dragon Pharma Preparations

Dragon Pharma offers multiple ancillary compounds discussed in bodybuilding contexts. Anastrozole's aromatase inhibitor mechanism contrasts with selective estrogen receptor modulators such as Nolvadex (tamoxifen), which blocks estrogen receptors rather than inhibiting estrogen production. It is also distinct from Aromasin (exemestane), which is a steroidal aromatase inactivator that binds irreversibly to the enzyme.

The distinction between Arimidex and these compounds is primarily one of mechanism: anastrozole reversibly inhibits aromatase, while exemestane irreversibly inactivates it, and tamoxifen blocks estrogen receptors without affecting estrogen levels.

Dosage & Usage

Arimidex 1 mg Dosage & Usage

The information below is provided for educational reference only. Anastrozole is a prescription medication approved for breast cancer treatment in postmenopausal women. Medical use requires appropriate diagnosis and clinical supervision. Non-medical use falls outside approved indications and is not recommended.

Typical Dosage Ranges

In medically supervised settings, the recommended dose of anastrozole is one 1 mg tablet taken once daily. In non-medical bodybuilding contexts, anastrozole is typically referenced at much lower doses, commonly 0.5 mg twice weekly starting from week two of an anabolic steroid cycle. A forum analysis reported a mean anastrozole dose of 0.4 mg over a median treatment duration of 70 days.

Use Case Common Reference Range Frequency
Medical (breast cancer) 1 mg / day Once daily
Bodybuilding (non-medical) 0.5 mg twice weekly Starting week 2 of cycle
Forum-reported mean (non-medical) 0.4 mg Median 70 days

Stacking & Cycle Considerations

In non-medical contexts, anastrozole is referenced alongside aromatizing anabolic steroids such as Testabol 400 or Dianabol 50 to manage estrogenic side effects. It may also be compared with Aromasin (exemestane), which is a steroidal aromatase inactivator. Dosing of anastrozole in this context should be based on individual response and bloodwork where possible.

Managing Side Effects

Anastrozole use can cause side effects including hot flashes, asthenia, arthritis, pain, arthralgia, pharyngitis, hypertension, depression, nausea and vomiting, rash, osteoporosis, fractures, back pain, insomnia, headache, peripheral edema, and lymphedema. Bone mineral density monitoring is recommended in patients treated with anastrozole due to observed decreases in lumbar spine and total hip BMD. Increased serum cholesterol has also been reported.

In women with pre-existing ischemic heart disease, an increased incidence of ischemic cardiovascular events was observed with anastrozole in the ATAC trial (17% of patients on anastrozole and 10% of patients on tamoxifen).

Frequently Asked Questions

Arimidex 1 mg FAQ

Answers to common questions about Arimidex 1 mg, anastrozole, aromatase inhibition, dosing, and safety.

What is Arimidex 1 mg used for?

Arimidex 1 mg contains anastrozole, a prescription aromatase inhibitor. It is FDA-approved for the treatment of hormone receptor-positive breast cancer in postmenopausal women. In non-medical bodybuilding contexts, it is referenced for managing estrogenic side effects of anabolic steroid cycles, though such use is not approved and is considered illegal.

How often should Arimidex 1 mg be taken?

In medical practice, the recommended dose is one 1 mg tablet taken once daily. In non-medical bodybuilding contexts, anastrozole is typically referenced at lower doses, commonly 0.5 mg twice weekly starting from week two of a cycle.

What does anastrozole do?

Anastrozole is a non-steroidal aromatase inhibitor. It blocks the aromatase enzyme, which converts androgens to estrogens, thereby reducing estrogen production. This mechanism is the basis for both its medical use in breast cancer and its non-medical use in bodybuilding for managing estrogenic side effects.

How long does Arimidex take to work?

Plasma concentrations of anastrozole approach steady-state levels at about 7 days of once-daily dosing. The half-life of anastrozole is approximately 50 hours, which supports once-daily dosing in clinical settings.

What is the half-life of anastrozole?

The mean elimination half-life of anastrozole is approximately 50 hours. Steady-state plasma levels are approximately 3- to 4-fold higher than levels observed after a single dose.

Is anastrozole the best aromatase inhibitor?

There is no universally "best" aromatase inhibitor. Anastrozole is a potent and specific non-steroidal inhibitor. Other options include Aromasin (exemestane), a steroidal inactivator, and Femara (letrozole), another non-steroidal inhibitor. The appropriate choice depends on the clinical context.

What is the difference between anastrozole and exemestane?

Anastrozole is a type II non-steroidal aromatase inhibitor that binds reversibly to the enzyme. Aromasin (exemestane) is a type I steroidal inactivator that binds irreversibly to the enzyme. Both reduce estrogen production but through different mechanisms.

What is the difference between anastrozole and tamoxifen?

Anastrozole is an aromatase inhibitor that reduces estrogen production. Nolvadex (tamoxifen) is a selective estrogen receptor modulator that blocks estrogen receptors without affecting estrogen levels. The two have different mechanisms and are not used in combination.

Is 1 mg of anastrozole a lot?

Medical anastrozole dosing is 1 mg per day for breast cancer treatment. In non-medical bodybuilding contexts, much lower doses are typically referenced, commonly 0.5 mg twice weekly. Arimidex 1 mg is labeled at 1 mg per tablet.

What strength is Arimidex 1 mg?

Arimidex 1 mg is labeled at 1 mg of anastrozole per tablet. It is supplied in a 100-tablet package, giving 100 mg of total labeled anastrozole content.

Is Arimidex 1 mg lab tested?

Yes. Published laboratory reports for Arimidex 1 mg are available. The most recent report dated September 02, 2025 measured the product at 1.05 mg per tablet, equivalent to 105.00% of its 1 mg label claim. Complete reports can be viewed in the Lab Reports tab.
