What is AfterDark Pharmaceuticals Estrozole?

AfterDark Pharmaceuticals Estrozole is an advanced anti-estrogen and hormonal support supplement in 90 capsules. It combines an aromatase inhibitor, Zinc, Magnesium, and supporting herbal extracts to help manage estrogen levels and support hormonal balance.

What is an aromatase inhibitor?

An aromatase inhibitor blocks the aromatase enzyme, which converts testosterone into estrogen. By inhibiting this process, Estrozole helps maintain a more favourable testosterone-to-estrogen ratio, particularly useful during or after a supplement cycle.

What are the key benefits of Estrozole?

Key benefits include anti-estrogen support, reduced risk of estrogen-related side effects, hormonal rebalancing, testosterone support via Zinc and Magnesium, and immune and recovery support via Vitamin D3.

Who is Estrozole designed for?

It is designed for adult males using prohormones, SARMs, or testosterone-based protocols who need to manage estrogen during or after a cycle. It is not suitable for women or individuals under 18.

Is Estrozole suitable for beginners?

Estrozole contains an active aromatase inhibitor and is best suited to experienced users familiar with cycle-based supplementation. Beginners should consult a healthcare professional before use.

Can Estrozole be stacked with other supplements?

Yes, Estrozole can be stacked with testosterone boosters or additional organ support products. It is designed to complement a complete PCT or hormonal management protocol.

What are the ingredients in Estrozole?

Key ingredients include Vitamin D3 1000IU, Magnesium (as Glycinate) 20mg, Zinc (as Glycinate) 30mg, and an aromatase inhibitor compound. Full ingredient details are available on the product label.

Is Estrozole safe? Are there any side effects?

Our opinion

Estrozole is more than just an estrogen blocker. AfterDark went the extra mile here — the inclusion of hair protection, organ support, and mood stabilisers makes it feel like a full PCT in a bottle. The formula hits all the right angles: estrogen, liver, DHT, and even mental clarity. Whether you’re coming off a strong cycle or want to manage estrogen naturally, this is one of the most well-rounded anti-estrogen supplements we’ve had on the shelf.

Ingredient Breakdown (per 3-capsule serving):

Vitamin D3 – 1000 IU

It is included for its essential role in hormone regulation, immune support, and testosterone synthesis. Often under-consumed, but crucial during any hormonal reset period.

Magnesium (as Glycinate) – 20mg

A bioavailable form of magnesium that supports muscle relaxation, sleep, and overall cellular health. Small dose, but synergistic with other recovery agents.

Zinc (as Glycinate) – 30mg

A well-absorbed form of zinc, critical for testosterone production and immune health. It also plays a role in the enzymatic activity involved in hormone conversion.

Selenium (as L-Selenomethionine) – 200 mcg

A trace mineral that contributes to antioxidant protection and thyroid function. It is included to support metabolic and hormonal recovery.

Aromatase Inhibition Complex

3,3′-Diindolylmethane (DIM) – 300mg

A potent estrogen modulator found in cruciferous vegetables. DIM supports healthy estrogen metabolism and is commonly used to maintain a favourable testosterone-to-estrogen ratio.

Indole-3-Carbinol (I3C) – 100mg

Often paired with DIM, I3C plays a similar role in estrogen detox and metabolism. It helps support hormonal clarity and reduce estrogenic side effects like bloating or mood swings.

Hepatic & Renal Cycle Support

Milk Thistle Extract (Steam Treated) – 500mg

Well-known for liver protection and detoxification. This high-quality form helps support liver enzyme levels and overall liver resilience, especially after a cycle.

N-Acetyl L-Cysteine (NAC) – 400mg

It supports glutathione production, antioxidant defence, and detox. Widely used to maintain liver and kidney function under stress.

L-Glutathione – 100mg

One of the body’s most powerful internal antioxidants, added here to support cellular detoxification and oxidative stress protection further.

Dihydrotestosterone (DHT) Hair Protection Complex – 265mg

A unique feature not often seen in similar products. This blend includes:

Saw Palmetto

– Frequently used to support healthy DHT levels and prostate function.

Mucuna Pruriens

– Included for L-Dopa content, supporting dopamine levels and natural test function.

Stinging Nettle Root

– Supports free testosterone by reducing SHBG binding.

L-Lysine
