Letros

Letros contains letrozole, a powerful non-steroidal aromatase inhibitor used to drastically reduce estrogen levels. It works by completely disabling the aromatase enzyme, stopping the conversion of androgens into estrogen.

Letrozole is the strongest aromatase inhibitor available. A single standard tablet can reduce estrogen levels by up to 98%. Because of this strength, it is sometimes used to address early-stage gynecomastia.

Letrozole may also increase natural testosterone production by stimulating LH and FSH, though this is not its main purpose. Due to its extreme potency, careful dosing is important. Too much estrogen suppression may cause fatigue, joint discomfort, and reduced overall performance.

For most users, very small doses are enough to control estrogen effectively while maintaining balance.
