Letrozole 2.5 - Prime Pharma

Letrozole was introduced as part of a new wave of aromatase inhibitors aimed at treating estrogen-sensitive cancers. Its development focused on achieving near-complete suppression of estrogen by targeting the aromatase enzyme. Unlike selective estrogen receptor modulators, it works upstream by stopping estrogen production altogether. While its medical use was focused on oncology, bodybuilders began using Letrozole to combat side effects like gynecomastia and bloating. Its strength required cautious dosing, especially in cycles involving highly aromatizing steroids.
