What are estrogen blockers?
Estrogen blockers, also called "estrogen blockers," are substances or medications that prevent female sex hormones from acting in the male body. They affect this in two ways: They either inhibit the production of estrogen in the male body or block existing estrogen. However, most products in the "estrogen blocker" category do not actually block estrogens, but rather inhibit their production. Prescription estrogen blockers such as tamoxifen, which occupy estrogen receptors and act as selective antiestrogens, are not found in supplements and are not available over the counter.
Why are estrogen blockers important?
The male body also normally produces estrogen, which is important for various functions such as blood vessel elasticity, tendon suppleness, maintaining fertility, and mood regulation. However, excessive estrogen levels can have negative effects.
In healthy men, the ratio of testosterone to estrogen is approximately 20:1. When testosterone levels rise sharply, as occurs with the use of anabolic steroids, excess testosterone is converted to estrogen. This can lead to problems. Even without anabolic steroids, an unhealthy diet, certain medications, or obesity can lead to an increase in estrogen levels.
Effect of estrogen blockers
Supplements in the "estrogen blocker" category inhibit the production of the enzyme that converts testosterone into estrogen. This keeps estrogen levels low. For athletes using anabolic steroids, estrogen blockers help prevent estrogen-related side effects, including fat storage, gynecomastia, water retention, increased blood pressure, loss of libido, and erectile dysfunction. They also support the body's return to normal after a cycle.
Who are estrogen blockers suitable for?
Not only steroid users benefit from these products, but also natural athletes. Men can experience elevated estrogen levels due to the consumption of hormone-laden foods and exposure to estrogen-like substances in packaging. Men with high body fat, in particular, are at increased risk for estrogen excess, as more body fat is often associated with higher aromatase activity.
Taking estrogen blockers can mitigate negative effects, improve quality of life, and support training progress. Many athletes have benefited from supplementing with an estrogen blocker, achieving a drier physique and better training results without changing their diet or training routine.
