Estrogen blockers are supplements which reduce estrogen levels. Estrogen is associated with the development of breast tissue in men and those with high estrogen levels will also tend to hold more body fat. The use of estrogen blockers, also known as anti-estrogens, will lower estrogen and, at the same time, increase testosterone providing a double benefit to users.
A substance that keeps cells from making or using estrogen (a hormone that plays a role in female sex characteristics, the menstrual cycle, and pregnancy). Estrogen blockers may stop some cancer cells from growing and are used to prevent and treat breast cancer. They are also being studied in the treatment of other types of cancer. An estrogen blocker is a type of hormone antagonist. Also called anti-estrogen.
Strictly speaking, estrogen blockers are a group of drugs that reduce either the production and/or effects of estrogen in your body.
Some common ones are…
- Arimidex (anastrozole)
- Aromasin (exemestane)
- Cytadren (aminoglutethimide)
- Femara (letrozole)
- N?lv?d?x (tamoxifen)
- Clomid (clomiphene)
The term “estrogen blocker” has also come to include natural supplements, though that contain various ingredients purported to positively impact your hormone profile, including resveratrol, grape seed extract, curcumin, maca, wild nettle root, and 3,3′-Diindolylmethane.
There are much more natural substances that are purported to balance or reduce estrogen levels, but we can save ourselves time and just cut to the chase:
None of them have ever been proven to work in healthy humans.
The Top Estrogen Blocker For Bodybuilders
Bodybuilders often research how to block estrogen due to the amount of testosterone generated by their lifestyle. They try to use estrogen blockers to help prevent gynecomastia, or the dramatic inflammation of the male breast. There are a few products out there that can help prevent the build up of estrogen in a bodybuilding routine. The products that are in this article are comprised of a couple of prescription products and a couple of over the counter (OTC) products that you can get a hold of.
- Arimidex® its generic name is Anastrozole and it was initially developed to help women prevent breast cancer. Essentially it is well known that the cause of breast cancer or the lump masses that are generated by it is caused by an increase in Estrogen production. The thought was that if the estrogen could be blocked then it could cause a reduction in breast cancer victims. This theory was not proved as a matter of fact but it was given that 65% of the women treated with Anastrozole or some variant compound wound up not acquiring the disease.
- Nolvadex® is typically used by bodybuilders as a post cycle treatment or PCT. This, however, is an inaccurate use of the product and is not who it was designed to treat. While similar in composition to Anastrozole it should be used in a similar context for the reduction of estrogen in men suffering from gynecomastia or for women wanting pre-treatment for breast cancer.
- Over the Counter (OTC) Estrogen Blockers – there are a few OTC estrogen blockers such as EstroBlox, or DIM however the primary element you are looking for are the natural estrogen blocker ingredients in each product to help you establixh which one is right for you. First off you want to look for pomegranate powder, tonkat ali, and dijndolyl methane. However, if you are looking for a purely organic estrogen blocker then dijndolyl methane would be out as it is a synthesized product not found purely in nature.
Prior to using an estrogen blocker you should review your workout goals. Are you trying to gain mass? if so this product most likely will NOT help you as blocking estrogen does not necessarily increase testosterone. If you are looking to increase testosterone then you need a test booster, not an estrogen blocker.
If you feel that you do in fact want to block estrogen then we recomment that you begin with an OTC first. However, it is an emergency then speak with your doctor and discuss gynecomastia treatment options.
