Anti Estrogen Supplements Side Effects
What are some benefits and side- effects of anti-estrogen/anti-aromatase as a nutritional supplement?
None: An anti-aromatase drug given to a post-menopausal woman is de facto an "anti-estrogen", since aromatase is the enzyme which converts ovarian testosterone and adrenal androgens to estrogens. They effectively block stimulation of hormone-sensitive cancers, but they have no place as a nutritional supplement as they markedly interfere with bone metabolism. ...Read more

I'm 22 female and want to know if taking supplemental estrogen can make my breasts grow, and what the side effects are. Also I have a regular period.
It can: Breast enlargement and tenderness are common with estrogen supplements. Common adverse effects are vaginal spotting, mood changes, headache or abdominal pain, weight gain (not all from breast enlargement). It increases risk of blood clots. When combined with progesterone, estrogen is a safe and common method of birth control. For breast enlargement in a healthy female, risk > potential benefit ...Read more
If taking an anti-estrogen/test booster (nolvadren xt) would I suffer any rebound effects of raised E when stopping supplementation?
Yes: Any time you take something that affects your natural production of hormones, there is typically a "withdrawal" that occurs as your body tries to return to its natural state. This is especially true with any "supplement" that affects testosterone production. That is why most of these supplements are banned or become banned once the governing bodies learn about them. ...Read more

The use in body builders is a bad ideas because of joint pain, cholesterol changes. Some are taken illegally to block side effects of androgen.

It may but not used: While it may help block growth of the breast cancers in women, it is generally not considered first line therapy for gynecomastia and is not indicated for this purpose. However, I recently had a patient whose endocrinologist prescribed this as an off label indication. You should first be fully evaluated by an endocrinologist. ...Read more
Yes. With the administration of clomiphene, an antiestrogen, approximately 50% of patients achieve partial reduction in breast size, and approximately 20% of patients note complete resolution.
Tamoxifen, an estrogen antagonist, is effective for recent-onset and tender gynecomastia. Up to 80% of patients report partial to complete resolution. Another drug is danazol. ...Read more

No: However, Aromasin (exemestane) has a lot of side-effects, and joint pain is one of the most frequent, occurring in around 15% of people who are taking the drug. There are alternatives to this medication, but unfortunately they all share the same side-effects. However, that said, it is never certain that you as an individual would not find an alternative less troublesome. Ask your doctor about this. ...Read more

I recently started androgel, Should I be concerned about an increase in estrogen? And is it okay to take an anti estrogen with trt therapy?
Good question: testosterone can & does convert to estrogen (estradiol), so increasing testosterone can result in increasing estrogen. Testosterone can compete with estrogen, but a surplus will make it more likely to increase the enzyme aromatase, which converts T to E. Additionally, testosterone from an external source will generally shut your own production down significantly after about 3-5 weeks ...Read more
No: As it is unregulated by the fda men taking it for big prostates may find that the actual amount of the substance is quite variable from each manufacturer and from batch to batch. Do not waste your money using it as an antiestrogen - your physician can write for generic anastrazole if it is appropriate for you. ...Read more
I am going ro start 200mg of test. Do I need an anti-estrogen? My doctor won't prescribe one. Thanks.
Tough decision: Testosterone metabolism will yield estrogen which may increase your breast tissue. The addition of an anti estrogen is a debatable issue because the estrogen gives you some cardiac protection and the addition of an estrogen blocker may allow for the development of cardiac disease. I would use the test and follow your lipid profiles every 6 mo or so. ...Read more
What is flax seed and is it considered photo estrogen or anti-estrogen? Also what is meant by testosterone?
Possibly both: Flaxseed is the seed of the flax plant. It is usually considered a phytoestrogen, a plant substance with properties similar to estrogen, but in young women with high estrogen, some phytoestrogens (soy, for example) may act as a anti-estrogen. Testosterone is the primary hormone of men (like estrogen is the primary hormone of women). Women, however, do make small amounts of it too in their ovaries. ...Read more
Neither: There is a huge amount of disinformation about foods being estrogenic or anti-estrogenic. It is almost all propaganda -- advertising and fringe politics -- rather than real science, and it's mostly just lies. I've seen a militant who makes false claims about chemicals estogenizing the environment & hurting men eating a tofu sandwich, which is among the highest sources of phytoestrogens. ...Read more
Gynecomastia: Generally, no treatment is required. Pubertal gynecomastia resolves spontaneously within several weeks to 3 years in approximately 90% of patients. Breasts greater than 4 cm in diameter may not completely regress. For patients with idiopathic gynecomastia or with residual gynecomastia after treatment of the primary cause, medical (antiestrogens) or surgical treatment may be considered. ...Read more

Starve tumor: Many tumors are fed by estrogen - the main female horomone. Anti-estrogen pills block the effects of estrogen (in a variety of different ways) and thereby starve the tumor from a vital growth factor. Even if you are postmenopausal (or even male) your body still produces estrogen in places like the adrenals and subcutaneous fat. ...Read more
With previous p.E from tamoxifen, what's the safest anti estrogen to use after an anabolic steroid cycle? Will be using arimidex (anastrozole) throughout for gyno
Possible: I do not now about the efficacy of anastrazole (arimidex) after anabolic steroid cycle (I am not sure what exactly you are referring to). However, both drugs and others are used for breast cancer treatment and prevention (for anastrazole, prevention study is ongoing). Unlike tamoxifen, the risk of blood clot with anastrazole is minimal. However, the risk of osteopenia and osteoporosis is higher. ...Read more
Anti-estrogen drugs: Anti-estrogen drugs are given to both premenopausal and postmenopausal women whose cancer is estrogen receptor-positive or progesterone receptor-positive. These cancer may grow when exposed to estrogen. Anti-estrogen medications block or reduce estrogen that is normally produced by the ovaries in premenopausal women or by fat cells, liver, adrenal glands or other organs in postmenopausal women. ...Read more
My wife has PCOS problem and she is taking Letrozole. Does Letrozole have anti-estrogen property and does it cause birth defects?
Generally no.: Flax seed is a good source of dietary fiber and it also contains some omega 3 fatty acids. Flax seed also contains some phytoestrogens, but generally not considered to be negative. Phytoestrogens appear to contain some positive health benefits when taken in moderation. A better source of omega 3 fatty acids would be fish oil. ...Read more
