Oestrogen

How Do Oestrogen Blockers Work and What are the Effects?

Marc Dressen“, you say, “I’ve heard that oestrogen can damage my workout… could oestrogen blockers help me to lose fat, and gain muscle the way I want to?”

The answer isn’t as simple as it might seem. A lot of people come to me wanting to know how to get a flat stomach and bigger muscles, and the outcome doesn’t usually involve focusing on the right combination of pills. However, there are countless fantastical claims out there that seem to suggest that the right supplements and blockers could give you the perfect physique.

People are constantly searching for more information about oestrogen blockers as they come to understand that testosterone levels are key to losing fat fast, and gaining muscle efficiently. Unfortunately, more testosterone can also mean more oestrogen, which leads to feminising effects, and higher levels of body fat.

So, how can you get the most out of your testosterone levels?

The answer, for most people, is to focus on keeping testosterone high, while keeping oestrogen low, to improve body composition and virility. Unfortunately, the oestrogen blockers you might have seen on the market up until now may not be as safe and effective as you think. Synthetic and natural oestrogen blockers can reduce your oestrogen levels.

But, there’s a catch.

Too little oestrogen could damage your body, and screw up your health too. In this article, we’re going to tell you everything you need to know about the complicated world of oestrogen. By the time you reach the conclusion, you’re going to understand exactly what role oestrogen takes in your body, and how you can build muscle more effectively.

What is Oestrogen, and What Are Oestrogen Blockers?

The only way to reach your goals in fitness, is to understand your body. Oestrogen is a natural part of the body, and a hormone that acts as a chemical messenger between your brain, and your cells. Oestrogen is produced mostly in women’s ovaries, and it can also be made in fat cells and adrenal glands. The primary purpose of oestrogen is:

  • To improve mood and alertness
  • Raise levels of insulin-like growth factor and growth hormone
  • Regulate menstrual cycles
  • Ward off infections in the urinary tract
  • Improve enzyme creation and muscle tissue repair

Oestrogen blockers are drugs that are intended to either reduce the effects, or production of oestrogen within the body. They range from things like Femara, to Clomid, Arimidex, and Aromasin. The somewhat broad term of “oestrogen blocker” has also come to refer to natural supplements, that contain a range of ingredients intended to improve the hormone profile, including curcumin, resveratrol, wild nettle root, and grape seed extract.

There are plenty of other natural substances out there that can help to reduce and balance estrogen levels, but the unfortunate truth is that none of them have been proven to work in humans. In other words, just like natural testosterone boosters – they’re a total scam.

The bottom line is that natural oestrogen blockers, simply aren’t going to change your hormone levels to help you figure out how to lose belly fat faster, or get more muscles. This means that you’d be better served spending your supplement money elsewhere.

So, why do People Take Oestrogen Blockers?

Just because the natural oestrogen blockers on the market today aren’t effective, doesn’t mean that their pharmaceutical cousins can’t be beneficial. In fact, pharmaceutical oestrogen blockers, originally developed to fight back against breast cancer, work remarkably well at reducing oestrogen – in some cases by as much as 90%.

Since many people claim that oestrogen blockers can be effective at helping fitness fans to build muscle faster by increasing testosterone levels, it makes sense that people would want to start reducing their oestrogen levels and building testosterone levels as quickly as possible. Research shows that oestrogen blockers can raise testosterone levels by as much as 50%.

The interesting part is that these drugs don’t seem to be capable of lifting testosterone levels in areas of skeletal muscle, which means that you won’t see many of the muscle-related benefits that are typically associated with testosterone production.

Another reason that hopeful bodybuilders and athletes continue to consider using oestrogen blockers, is that some scientists claim that these substances can help to enhance workout performance, thereby improving your chances of working harder and faster at the gym. As of this time, no studies have been able to demonstrate that oestrogen blockers can truly improve athletic performance, and there are some suggestions that these substances may even worsen your athletics.

In fact, one of the most common side-effects of using oestrogen blockers is increased fatigue, because oestrogen is key to sharper focus and higher attention spans. In other words, your workouts could become notably worse.

Oestrogen Blockers: What are the Side Effects?

Ultimately, research suggests that oestrogen blockers are often safe to use if you’re only taking them for short periods of time. However, there is some indication that long-term use could lead some significant health problems.

For instance, some studies show that oestrogen-blocking drugs could increase your risk of bone fracture, joint pain, and osteoporosis, as well as raising triglyceride, and cholesterol levels. There’s also an increased risk of stroke and heart attack in people taking oestrogen blockers, and some concern surrounding deep vein thrombosis.

It’s worth noting, however, that most of the human research that has been carried out around oestrogen blockers was conducted among women fighting back against breast cancer. In other words, it’s hard to know what the side effects could be for healthy people, and there are also no long-term studies into men.

Should you Be Taking Oestrogen Blockers?

If you’re searching for a results-driven solution to fat loss and muscle gain, then you should probably ignore oestrogen blockers. Although there are a handful of drugs out there that have been proven to work at greatly limiting your oestrogen levels, these drugs are unlikely to help you lose fat faster, or gain strength more effectively.

At the end of the day, instead of attempting to speed up your progress with the use of some kind of “hormone system hack” using oestrogen blockers and other supplements, think about following the basic guide for success, with training, diet, and rest.
