Letrozole / Femara Anti-estrogen/ PCT Powder

How Letrozole Works

Letrozole is basically an aromatase inhibitor or AI, which means that it prevents the aromatase enzyme from converting androgens or male hormones like testosterone and androstenedione into estrogen. This doesn’t just keep the existing testosterone levels of the body intact, but also helps raise the amount of “free” testosterone while at it.

Letrozole Half-Life

The half-life of Letrozole is approximated at 2 days after administration. However, the blood plasma levels of the users should also be taken into account. Individuals whose blood plasma levels are slower in terms of reaching their peak levels tend to have Letrozole in their system for up to 4 days.

Letrozole Side Effects

Although Letrozole is considered as a safe drug to use, it still has a few side effects that you should keep an eye on when you’re looking to use it for your PCT needs. Besides mild swelling of the extremities, shortness of breath, bouts of lethargy, seasoned bodybuilders also emphasize that the use of Letrozole can set off sudden episodes of chills and flu-like symptoms, as well as fleeting chest pains.
Letrozole is a non steroidal selective third generation aromatse inhibitor. The structure and activity of this compound are very similar to that of Arimidex, and is prescribed for similar medical reasons. More specifically, United States prescribing guidelines for letrozole recommend it to be used for the treatment of postmenopausal women with estrogen receptor positive or estrogen receptor unknown brest cancer. It is typically used as a second line of treatment after an estrogen receptor antagonist like tamoxifen has failed to elicit a desirable response, although it is sometimes initiated as the first course of therapy depending on the circumstances. Male bodybuilders and athletes find value in letrozole for its ability to mitigatge the estrogenic side effects associated with the use of aromatically anabolic/androgenic steroids, such as gynecomastia, fat buildup, and visible water retention. The U.S. FDA approved letrozole for prescription sale in 1997, where it is sold by  the pharmaceutical company Novartis under the brand name of Femera. The company also markets the drug in over 70 nations worldwide. The drug is most commonly supplied in dosages of 2.5mg.
