Aromatase Inhibitors (AI)

Aromatase inhibitors (AIs) are a critical part of any serious post-cycle therapy or on-cycle estrogen management plan. These compounds work by blocking the aromatase enzyme responsible for converting testosterone into estrogen. When estrogen levels rise too high during a steroid cycle, users can experience bloating, gynecomastia (development of breast tissue in men), water retention, and mood fluctuations.

Dragon Pharma offers pharmaceutical-grade AIs such as Anastrozole, Letrozole, and Exemestane. These compounds are widely used by bodybuilders and performance athletes to maintain a dry, lean look and avoid the common side effects of estrogen dominance. Whether you're mid-cycle or entering PCT, using aromatase inhibitors can help you protect your gains and stay hormonally balanced.

When to use AIs: Aromatase inhibitors are typically taken on-cycle when using aromatizing compounds like testosterone, Dianabol, or boldenone. They can also be used in lower doses during post-cycle recovery to prevent rebound estrogen spikes.

Why Dragon Pharma: Every AI in this category is lab-tested, manufactured to high standards, and trusted by competitive athletes worldwide. With Dragon Pharma's AIs, you get consistent dosing, reliable results, and full transparency.
