How much Arimidex should I take on cycle?

This depends on the aromatising load of your cycle. Many users start with 0.25-0.5mg every other day on moderate-dose testosterone cycles and adjust based on symptoms or bloodwork (estradiol levels). Higher aromatising doses may require up to 0.5-1mg every other day to daily.

What is the difference between Arimidex and Nolvadex?

Arimidex (Anastrozole) is an aromatase inhibitor that reduces estrogen production by blocking the aromatase enzyme. Nolvadex (Tamoxifen) is a SERM that blocks estrogen at the receptor level without reducing overall estrogen production. They work through different mechanisms and are sometimes used for different purposes — Arimidex on-cycle for estrogen control, Nolvadex primarily for PCT.

What are the signs of taking too much Arimidex?

Signs of "crashed E2" from excessive Arimidex use include joint pain and stiffness, low libido, fatigue, mood disturbances and flat or depressed feelings. If these symptoms appear, reducing or temporarily stopping Arimidex is the standard response.

Should I take Arimidex every day?

Not necessarily. Due to Anastrozole's roughly 46-hour half-life, every-other-day dosing is common for moderate aromatising loads, while daily dosing may be used for higher aromatising compounds like Dianabol. The right frequency depends on total aromatising load.

What is the difference between Arimidex and Aromasin?

Arimidex (Anastrozole) is a non-steroidal AI that reversibly binds the aromatase enzyme, making small dose adjustments more forgiving. Aromasin (Exemestane) is a steroidal AI that binds irreversibly, and some users report it has less negative impact on lipid profiles.

Can I use Arimidex during PCT?

Some users include a low dose of Arimidex during PCT if estrogen rebound is a concern, though others avoid combining AIs with SERMs unless specifically needed, as PCT SERMs already address estrogen receptor activity through a different mechanism.

Anastrozole — Arimidex by Dragon Pharma

Arimidex is Dragon Pharma's formulation of Anastrozole at 1mg per tablet — the most widely used aromatase inhibitor (AI) for managing estrogen-related side effects during anabolic steroid cycles. Supplied in a 100-tablet pack, Arimidex allows precise control over estrogen conversion from aromatising compounds such as testosterone.

What Is Anastrozole (Arimidex)?

Anastrozole is a non-steroidal aromatase inhibitor that works by binding to the aromatase enzyme — the enzyme responsible for converting testosterone into estrogen. By inhibiting this enzyme, Anastrozole reduces circulating estrogen levels, which is the primary mechanism behind managing estrogen-related side effects from aromatising anabolic steroids. Unlike SERMs (such as Nolvadex) which block estrogen at the receptor level, Anastrozole reduces estrogen production itself.

Effects and Benefits

Reduces circulating estrogen levels by inhibiting the aromatase enzyme
Manages water retention and bloating caused by elevated estrogen on aromatising compounds
Reduces the risk of gynecomastia developing during a cycle with testosterone or other aromatising AAS
Can help manage blood pressure increases that are partly estrogen-driven
Used both on-cycle (to manage estrogen from AAS) and during PCT (to support the hormonal recovery environment)

Dosage and Administration

Use Case	Typical Dose	Frequency
On-cycle, moderate aromatising doses	0.25–0.5 mg	Every other day
On-cycle, higher aromatising doses	0.5–1 mg	Every other day to daily
PCT support	0.5 mg	2–3 times per week, as needed

Anastrozole is typically dosed in fractions of a tablet — splitting the 1mg tablet into quarters (0.25mg) is common for on-cycle dosing. The correct dose depends heavily on the aromatising load of the compounds being used and individual aromatase activity; many users start at the lower end and adjust based on symptoms and, ideally, bloodwork (estradiol levels).

Over-suppression of estrogen ("crashed E2") causes its own set of problems — joint pain, low libido, fatigue and mood disturbances. Anastrozole should be dosed conservatively and adjusted based on symptoms or bloodwork rather than used at a fixed high dose by default.

Side Effects

Anastrozole's side effects are primarily related to estrogen suppression itself, particularly when overused:

Joint pain and stiffness — estrogen plays a role in joint lubrication, and excessive suppression can cause noticeable discomfort
Negative impact on lipid profile (cholesterol) — estrogen has a protective effect on lipids that is reduced when suppressed
Reduced libido and mood disturbances if estrogen is suppressed too far ("crashed E2")
Does not itself suppress testosterone production — Anastrozole is not a substitute for Post Cycle Therapy SERMs, which work through a different mechanism

Arimidex vs Aromasin

Dragon Pharma offers two aromatase inhibitors with different mechanisms:

Arimidex (Anastrozole) — a non-steroidal AI that reversibly binds the aromatase enzyme; easier to fine-tune with small dose adjustments due to its reversible action
Aromasin (Exemestane) — a steroidal AI that binds the aromatase enzyme irreversibly ("suicide inhibitor"); some users report it has less negative impact on lipid profiles and may help restore HPG axis function during PCT

Both are effective at reducing estrogen — Arimidex's reversible mechanism makes small dose adjustments more forgiving, while Aromasin's irreversible mechanism and reported lipid-friendliness lead some users to prefer it, particularly during PCT.

When and How Arimidex Is Used in a Cycle

Arimidex is commonly paired with aromatising compounds:

Cypionat 250, Enantat 250 or other testosterone esters — the primary aromatising compounds most users run Arimidex alongside
Dianabol — a strongly aromatising oral often requiring AI from the start of the cycle
Nolvadex or Clomid — Arimidex is sometimes used alongside SERMs during PCT, though some users avoid combining AIs with SERMs unless estrogen rebound is a specific concern

"Arimidex is formulated for precise 1mg dosing, allowing our customers to split tablets for the small, conservative doses that estrogen management on cycle typically requires."

Storage and Handling

Store Arimidex at room temperature, away from direct sunlight and moisture. Keep the original packaging sealed until use to maintain tablet potency over the product's shelf life.
