Aromex - 25MG - 30T
Aromasin is extremely effective at 25mg daily for the reduction of serum circulating Estrogen levels in the body, as demonstrated earlier with its ability to reduce Estrogen by 85%. As with other second-line breast cancer treatments, Aromasin is so effective at inhibiting the aromatase enzyme (and thereby reducing Estrogen levels) that this compound is, like Arimidex, only administered to post-menopausal females, and/or utilized when other first-line treatments for breast cancer has failed. This is because post-menopausal females possess a very different shift in hormone levels and endocrine function in comparison to pre-menopausal females.
Arimidex and Letrozole are both classified as non-steroidal and non-suicidal aromatase inhibitors that compete with the substrate for binding to the enzyme active site. This is very different from Aromasin (Exemestane), which is a steroidal and suicidal aromatase inhibitor that acts as a mechanism-based steroidal inhibitor that mimics the substrate, is converted by the enzyme to a reactive intermediate, and results in the inactivation of the aromatase enzyme. For ease of understanding, what this means to the layman is that Aromasin’s chemical structure resembles the traditional ‘targets’ that aromatase binds to (Testosterone, for example) and that it essentially ‘fools’ the aromatase enzyme into binding with it, only to become inhibited/deactivated. Because the binding strength is so great, this inhibition becomes permanent for the aromatase enzyme that Aromasin has become bound to. Arimidex and Letro, being non-suicidal aromatase inhibitors, both compete with the enzyme’s traditional ‘targets’ rather than being assured a permanent spot (which is the advantage that Aromasin has over the other two).
Athletes, bodybuilders, and individuals engaging in the use of anabolic steroidswill favor the use of aromatase inhibitors such as Aromasin for their usefulness in reducing, mitigating, and avoiding Estrogenic side effects. These side effects are result of the aromatazation (or conversion) of aromatizable androgens (such as Testosterone) into Estrogen, which often results in far greater than normal physiological levels of Estrogen in the body. This is where the use of Aromasin (Exemestane) is very beneficial and highly favored among anabolic steroid using individuals, as Aromasin eliminates the issue of rising Estrogen levels at the root cause: By binding to and inhibiting/disabling the aromatase enzyme, supraphysiological levels of aromatizable androgens (such as Testosterone, Dianabol, Boldenone, etc.) cannot convert into Estrogen, thereby eliminating any possible risk of Estrogen-related side effects.
