You’ve probably heard about estrogen blockers and how they can help you gain muscle and lose weight in a short amount of time. It’s common knowledge that raising your testosterone level will improve bone density and sexual performance, but do they actually work? In this article, we’ll examine what estrogen blockers do for the male body.

What Are Estrogen Blockers?

Estrogen blockers are a group of drugs that reduce the production of estrogen in the body. There are plenty of ingredients in these drugs that help stall estrogen in the body, like grape seed extract, resveratrol, curcumin, wild nettle root, and maca. Many blockers will render the enzyme aromatase ineffective, thus reducing overall estrogen levels.

Physical Effects of Estrogen Blockers

The most common use for estrogen blockers for men is to improve performance in the gym and bedroom. Estrogen blockers help boost overall energy levels in most men who take it in the morning before a workout. Testosterone can also improve mood and promote better sleep.

Let’s look at how over-the-counter estrogen blockers can help you more in-depth.

Building Muscle and Increases Strength

Testosterone is tied to muscle and bone mass in men. Having low T-levels can cause you to grow more fat in your chest and hips, which isn’t what you’re looking for when making serious gains. Estrogen blockers work as a muscle builder by promoting muscle fullness during training and reduces the effects of muscle catabolism (aka energy).

More Energy and Vitality

It can be challenging to get through those heavy workouts, especially when you’ve already worked a physically demanding job. Estrogen blockers will boost your overall energy levels to help you power through workout sessions and everyday life. You’re more likely to feel restless than tired while on blockers because extra testosterone will make men more alert.

Improved Mood

Testosterone regulates mood and improves your overall quality of life. Men who are tested to have low T-levels are typically irritable, depressed, and tired, making them even moodier. To make matters worse, anxiety is rampant in men who have difficulty regulating their emotions. Having a better disposition will benefit your workouts and personal life.

Better Libido

Male testosterone naturally rises in response to sexual arousal and activity, and men with higher testosterone usually have a greater need for sexual activity. Testosterone therapy and estrogen blockers and benefit your sexual health and performance. If erectile dysfunction is associated with lower T-levels, a decrease in estrogen may solve the problem.

Medical Effects of Estrogen Blockers

Pharmaceutical estrogen blockers, aka the type of antiestrogens that require a prescription, are incredibly effective at managing multiple diseases. Estrogen blockers are an effective treatment for breast cancer patients and women with anovulation.

Antiestrogens are also a component of hormone replacement therapy in transgender men. Many transgender men will use both medical antiestrogens and over-the-counter estrogen blockers to improve the effectiveness of their transition.

When considering this medication, always consult with a doctor as there may be side effects of estrogen blockers in men when not administered properly.

In men, estrogen blockers are used to treat the following conditions:

Male Hypogonadism

Hypogonadism is a condition that diminishes the functionality of the testes due to low testosterone levels. Hypogonadism can decrease other hormones secreted by the testes and affects sperm development. A doctor will administer a dosage of estrogen blockers and possible testosterone enhancers until the patient reaches normal levels. Typically, the effects of hypogonadism will cease once men reach optimal T-levels.


Gynecomastia is the abnormal non-cancerous enlargement of one or both breasts due to a hormonal imbalance. While there aren’t any long-lasting effects due to gynecomastia, the condition often causes unease and psychological distress in men who have it. Gynecomastia is the most common disorder that affects the male breast tissue.

Estrogen blockers are an effective treatment for abnormal breast growth because it pulls fatty tissue away from the chest and hips and into the abdomen. Coupled with exercise, most men can effectively keep this fat off as long as their testosterone levels stay at normal levels.
