Letrozole 2.5mg UK by AASScripts is an ultra-potent non-steroidal aromatase inhibitor (AI) designed to combat excess estrogen during or after anabolic steroid cycles. Often sold under the brand name Femara®, Letrozole is known for its strong estrogen-suppressing properties, making it ideal for users prone to gynecomastia, bloating, and other estrogenic side effects.

Letrozole works by binding to the aromatase enzyme, completely stopping the conversion of androgens to estrogen. It is commonly used by bodybuilders during bulking and cutting cycles, and also as a pre-contest preparation tool to eliminate water retention and enhance muscle definition.

It’s more potent than Arimidex or Exemestane, so it should be used with caution and proper monitoring. Some users also include Letrozole in their Post-Cycle Therapy (PCT) to prevent estrogen rebound, especially after using aromatizing compounds like Testosterone Enanthate, Dianabol, or Sustanon.
