Originally developed for breast cancer treatment and fertility support, it has gained popularity in bodybuilding for its ability to eliminate estrogen and prevent gynecomastia during anabolic steroid cycles.

Whether you're using Letrozole for infertility, PCT, or as an on-cycle AI, this guide explains how to use it safely and effectively.

💡 What Is Letrozole Used For?

✅ In Bodybuilding:

• Prevents estrogenic side effects (gyno, water retention, bloating)

• Used in Post Cycle Therapy (PCT) or on-cycle estrogen control

• Supports dry, hard muscle look by eliminating excess water

✅ In Fertility Treatments:

• Stimulates ovulation in women with PCOS or ovulation issues

• Prescribed off-label as a safer alternative to Clomid

• Often used in 5-day protocols to induce egg release

🧬 Letrozole works by blocking aromatase, the enzyme that converts testosterone into estrogen.

❓ Does Letrozole Cause Toenail Issues?

⏳ What Happens When You Stop Taking Letrozole?

• In some, it can spike if not tapered

• For fertility patients, ovulation often occurs after stopping the dose
