Xtane is an oral drug manufactured by Natco Pharma based on the substance Exemestane (known as Aromasin). In the medical field, this drug is used in the treatment of breast cancer. In the world of fitness, the drug is used by those who take steroids to prevent male hormones (androgens) from converting to female ones (estrogen). This conversion is called aromatization and can cause some unwanted side effects in a man's body.
How it works
Aromasin is able to block the aromatase process, which occurs when androgenic steroids such as Testosterone, Methandienone or Boldenone are taken. When these steroids are used by men, the amount of testosterone in the body increases. Much of this testosterone, however, is converted by the aromatase enzyme into estrogen, which causes estrogenic side effects such as gynecomastia, water retention, and acne. Exemestane is an aromatase inhibitor (IA), which means that it binds to the aromatase enzyme and prevents it from acting on testosterone. This process can reduce the level of estrogen in the blood by 85%, which reduces the amount of side effects. Additionally, as a result of the process itself, much more testosterone will remain in the blood, meaning the user will benefit from it, in the form of a potential decrease in body fat and improved muscle definition.
Since the most typical and well-tolerated dose of Exemestane is 25 mg per day, most pharmaceutical companies, including Natco Pharma, have produced the drug in 25 mg tablets.This means that, generally, 1 tablet per day is taken orally, both to eliminate side effects and to keep estrogen levels in check during a steroid cycle.
Some people may need it in a smaller amount, in which case, the frequency of use can be reduced to one dose every 2 days. The optimal dose largely depends on how aromatizable the steroids are being taken, as well as the dosage of the steroids used in the cycle. Therefore, to define the right amount to take, it is advisable to consult a specialist.
