Letrozole

Letrozole is a powerful aromatase inhibitor. The drug is appropriately used when using substantial amounts of aromatizing steroids, or when one is prone to gynecomastia and using moderate amounts of such steroids. Letrozole can achieve a high degree of estrogen blockade. It is possible to reduce estrogen too much with Letrozole, and for this reason tests, should be taken after the first week of use to determine if the dosing is correct.

DOSAGE & INSTRUCTIONS
Letrozole, even at low doses, is a potent drug so a little goes a long way to recieve the benefits. Does usually start around 2.5mg daily, we would look at no higher than that and most of the time even lower. To protect from estrogen related side effects during steroid use a dose of as low as 0.5mg to 1.25mg every two days is often enough for excellent estrogenic related protection for most men.

Possible Side Effects
Fatigue, Muscle aches, Pain in joints or bones Diarrhea or constipation, Chest pain
