Aromatase inhibitors (10 Offers)
Aromatase inhibitors / GbnStore.top
The primary function of aromatase inhibitors is to block the enzyme aromatase, which converts testosterone into estrogen. Elevated estrogen levels can lead to undesirable side effects in bodybuilders, including water retention, gynecomastia (enlargement of breast tissue in men), and fat gain. By inhibiting aromatase activity, AIs help maintain a favorable testosterone-to-estrogen ratio, promoting muscle growth, strength gains, and a leaner appearance.
