Exemestane (Aromasin)

Mechanism of Action & Benefits:

Aromasin, also known as exemestane, is a medication that serves as an aromatase inhibitor (AI). In the context of bodybuilding, Aromasin is used off-label to manage estrogen levels that can rise due to the use of anabolic steroids. The mechanism of action of Aromasin involves the irreversible inhibition of the aromatase enzyme, which is responsible for converting androgens, such as testosterone, into estrogen. By blocking this conversion, Aromasin effectively reduces estrogen levels in the body, which can help prevent estrogen-related side effects such as gynecomastia (enlargement of male breast tissue).

The benefits of Aromasin in bodybuilding include:

  • Prevention of Gynecomastia: By lowering estrogen levels, Aromasin can help prevent or treat gynecomastia, which is a common concern among steroid users.

  • Improved Muscle Definition: Reduced estrogen levels can decrease water retention, leading to a more defined and vascular physique.

  • Retention of Lean Muscle Mass: Aromasin may help preserve lean muscle mass during steroid cycles by preventing the negative effects of excess estrogen.

Side effects & Interactions:

Side Effects of Aromasin

Aromasin can cause both mild and serious side effects. Mild side effects include joint pain, hair loss, weight gain, headache, and nausea. More serious side effects include high blood pressure, depression, bone loss (which can increase the risk of fractures and osteoporosis), heart-related problems such as heart attack, chest pain, or heart failure, and allergic reactions. Other side effects can include hot flashes, fatigue, increased appetite, insomnia, pain in the back, arms, or legs, dizziness, tingling in the arms or legs, diarrhea, muscle pain, swelling (especially in the legs or ankles), and hair loss.

Drug Interactions with Aromasin

Aromasin can interact with other medications. For example, co-medications that induce CYP 3A4 (such as rifampicin, phenytoin, carbamazepine, phenobarbital, or St. John's wort) may significantly decrease exposure to exemestane, the active ingredient in Aromasin. There are 90 drugs known to interact with Aromasin, with 16 of these interactions being major and 74 being moderate.

Disease Interactions with Aromasin

Aromasin can also interact with certain diseases. For example, taking Aromasin can cause some bone loss, especially when used long term. If you have osteoporosis, you should let your doctor know before taking Aromasin. There are two known disease interactions with Aromasin.

Dosing Guidelines:

The dosage of Aromasin, also known as exemestane, can differ depending on individual requirements and the specific substances incorporated in a steroid cycle. In the bodybuilding context, typical dosages often range from 12.5mg every alternate day to 25mg daily.

It's crucial to regularly monitor and adjust the dosage to avoid excessive suppression of estrogen levels. Aromasin should only be used when bloodwork indicates elevated estrogen levels, as this can help mitigate the risk of a sudden drop in estrogen, often referred to as an 'estrogen crash'.
