E-Block by Core Labs X: highly effective aromatase inhibitor

One of the biggest problems with the use of hormone-based performance-enhancing drugs is aromatase, the conversion of testosterone to estrogen. As soon as testosterone levels in the (male) body rise to an abnormal level, the enzyme CYP19A1 is released. This converts part of the testosterone into the female sex hormone estrogen – this is how the body attempts to restore hormonal balance. The result is water retention and fat accumulation in the chest, hip, and thigh areas. Estrogen blockers help combat the unwanted conversion of testosterone to estrogen. They prevent the release of the aromatase enzyme, so that estrogen levels remain low despite high testosterone levels. Therefore, it is highly recommended to take an estrogen blocker during or after a course of prohormones or anabolic steroids.

What makes E-Block from Core Labs X special?

E-Block by Core Labs X contains the drug anastrozole, which is also found in the drug Arimidex®. Anastrozole is a nonsteroidal aromatase inhibitor and was originally developed to treat breast cancer in women. In the fitness world, anastrozole is considered one of the most effective estrogen blockers. In addition to anastrozole, E-Block also contains N-acetyl-L-cysteine, vitamin E (TPGS), and rosemary extract. All three of these substances are powerful antioxidants; they increase cell protection and are particularly beneficial for the liver—the organ most stressed during a steroid cycle.
