What is Exemestane?


Exemestane is used in medicine to treat early-stage breast cancer in women. It is a potent antiestrogen that works through aromatase inhibitors.


Aromatase is an enzyme that helps produce estrogen in men and postmenopausal women. If this particular hormone is inhibited or blocked, there is a considerable fall in the body's estrogen level. Studies show that it can suppress more than 70% of estrogen production.


What is the role of Exemestane in bodybuilding?

Since it is primarily used to manage breast cancer and suppress estrogen production in postmenopausal women, it is logical to ask about its role in bodybuilding. In sports, it is used by people who regularly use anabolic steroids at higher doses. It is used as a part of post cycle therapy (PCT).


Some of the goals of PCT are to normalize the body's production of testosterone and at the same time reduce specific side effects of high-dose steroids.


Exemestane (also called Aromasin) can stimulate luteinizing and follicle-stimulating hormones, and thus boosting post cycle production of testosterone. It may help normalizing testosterone production from testicles.


However, it is also a potent inhibitor of estrogens that are needed in smaller amounts by men. Sports medicine experts view this as its downside. Potent suppression of estrogen is not good for the revival of the normal production of testosterone. It means that in many individuals, Exemestane may work insufficiently.


Nevertheless, it may be suitable for certain population groups. Since it is a potent suppressor of estrogen production, it might be quite good for preventing steroids-related gynecomastia (breast enlargement) in men.


Exemestane dosage

For most individuals, 25 mg/day is sufficient, taken for 2-weeks. It is also safe to combine with other aromatase inhibitors like Nolvadex (Tamoxifen).


For female athletes, a much lower dosage of 12.5 mg (half a tablet) used twice a week may work. Females need much lower dosage, as they need not suppress estrogen production like men.


Is Exemestane safe?

Toxicological studies show that it is a very safe drug. Even 25 to 35 times of recommended dosage did not cause any severe side effects in human clinical trials. It means that Exemestane does not cause any acute toxicity or life-threatening side effects even when accidentally overdosed.


However, it is worth knowing that milder side effects with prolonged use are pretty frequent. Since it causes estrogen deficiency, it might cause hot flushes, sweating, loss of appetite, headaches, fatigue, joint pain.


It is not recommended for people living with low immunity, like those diagnosed with HIV. Studies show that in about 20% of instances, it may reduce lymphocytes. It is not a reason to worry for most sportspeople, as this effect is only seen in prolonged use like that for months and is rarely caused by shorter use of few weeks.


To conclude, Exemestane is one of the newer and most potent aromatase inhibitors. It may be well suited for two-week PCT, rarely causing any side effects. On the downside, it is less tested for such use than more popular Nolvadex. It might be a better option for those who cannot tolerate Nolvadex well or those more prone to gynecomastia. For frequent users of anabolic steroids, it makes sense to use Exemestane instead of another aromatase inhibitor, from time to time, as this may be a safer strategy.
