Letrozole is a non steroidal selective third-generation aromatase inhibitor.
The structure and activity of the compound are very similar to the structure
and activity of Ahna's trazole, and the clinical use is also consistent. The
US prescription guidelines for letrozole suggest that it be used to treat
breast cancer with estrogen receptor positive or estrogen receptor unknown
postmenopausal women (not sure if cancer is reacting to estrogen). After
estrogen receptor antagonists such as tamoxifen fail to cause the required
response, they are usually used as the second therapeutic agent, and
sometimes as the first therapeutic agent according to the situation. Male
bodybuilders and athletes have found the ability of letrozole to reduce
anabolic / androgen steroid related estrogen side effects, such as male
breast development, fat accumulation and increased moisture.

Letrozole is one of a series of new drugs for aromatase inhibitors. It is
the most effective estrogen lowering drug developed so far, and has a
stronger effect than non selective first generation aromatase inhibitors
such as Tesla and amlumide. The dose of letrozole per tablet is 2.5 mg,
which is sufficient to reduce estrogen levels by an average of 78% during
clinical use according to product information. The drug also generally
maintains fairly effective properties at lower doses. The instructions of
the product point out that the low and medium doses in clinical studies are
0.1 and 0.5 mg respectively, which can produce 75% and 78% estrogen
inhibition in many patients, respectively. The recommended dose also caused
the required level of inhibition in almost all patients. Therefore, many
people may not need a dose of 2.5mg and only need half a tablet to obtain
good results.

The recommended dose for medical treatment is 2.5mg per day to reduce the
increase of estrogen in anabolism. It only needs 1.25mg per week for
testosterone below 800mg and body fat below 15% to suppress estrogen. It
usually needs 2.5mg letrozole per day for testosterone above 1000mg per
week. The specific dose is adjusted according to different physique. Please
refer to the specific situation for specific analysis.
