Letroxyl is a pharmaceutical-grade aromatase inhibitor manufactured by Kalpa Pharmaceuticals. It contains 2.5 mg of Letrozole, the same active compound found in Femara. Letrozole is widely used in bodybuilding cycles to control estrogen levels, manage water retention, and prevent gynecomastia.
Letrozole belongs to a class of drugs called aromatase inhibitors. It works by inhibiting the aromatase enzyme, which converts androgens into estrogens. Clinical studies have shown Letrozole to be highly effective in suppressing estrogen—beneficial for both cancer treatment and hormonal control in steroid cycles.
Letroxyl is commonly stacked with testosterone-based compounds such as Testoxyl Enanthate or Testoxyl Cypionate. It can also be used in cycles involving aromatizable steroids like Dianoxyl 20.
Though Letrozole is not the first-line compound for PCT, some athletes incorporate it in low doses to quickly lower estrogen after a heavy cycle. For more comprehensive recovery, products like Nolvaxyl or Clomixyl are often preferred.
If you're searching for a reliable Kalpa Femara alternative, Letroxyl offers the same compound at pharmaceutical purity. It ships to the USA discreetly and efficiently.
Letroxyl helps control estrogen levels during anabolic steroid use, reducing water retention and the risk of gynecomastia.
Letroxyl is not typically the first choice for PCT, but it may be used briefly to manage high estrogen levels post-cycle before switching to SERMs like Clomixyl or Nolvaxyl.

The Femara was great. No issues whatsoever, even when test was increased to over a gram a week. Dosed at 2.5 eod. Effective product.
