When testosterone levels are high, estrogen levels also tend to increase as a natural byproduct. “All they do is block estrogen,” Fred Rowlett, president of the North American Natural Bodybuilding Federation, said of the nonchalant attitude weight lifters have about taking cancer drugs.
Why do bodybuilders take estrogen blockers?
Arimidex is a treatment for breast cancer that some bodybuilders take to reduce the side effects of anabolic steroids. The drug lowers estrogen levels in the body. Bodybuilders who take anabolic steroids to try to increase muscle mass and improve athletic performance can experience a range of symptoms.
What do estrogen blockers do for males?
One reason people think estrogen blockers are prescribed is to treat swelling of breast tissue in males (gynecomastia), a rare medical condition where a young male grows breast tissue that resembles female breast tissue. This condition is extremely rare in older males, even males on testosterone therapy.
Why do bodybuilders use aromatase inhibitors?
Aromatase inhibitors may be used to treat or prevent gynecomastia. They may be used to increase gonadotropin secretion and thereby stimulate Leydig and Sertoli cell function. Aromatase inhibitors may be used to prevent or delay epiphysial closure and thereby increase adult height.
Does high estrogen prevent muscle gain?
All together, the existing data suggest that acute treatment with estrogen does not improve basal muscle protein synthesis; however, estrogen increases the anabolic response to exercise and this may result in the increase in muscle mass reported in long term studies.
What is the best anti estrogen?
an aromatase inhibitor is the best hormonal therapy to start with. When treating early-stage, hormone-receptor-positive breast cancer, aromatase inhibitors have more benefits and fewer serious side effects than tamoxifen.
Do estrogen blockers cause weight gain?
Studies have shown that weight gain is not increased in women taking tamoxifen or anastrozole, but it is harder to study the effects of these drugs on a woman’s ability to lose weight. Regardless of the reasons for weight gain, weight loss requires calorie reduction.

Will estrogen blockers get rid of gynecomastia?
Given that estrogen isn’t a direct cause of man boobs, estrogen blockers cannot get rid of them.
What is the best aromatase inhibitor?
Anastrozole, exemestane and letrozole are equally effective and have similar side effects [79,90-93]. However, you may tolerate one drug better than another. For a summary of research studies on aromatase inhibitors and early breast cancer, visit the Breast Cancer Research Studies section.
How long does it take for Arimidex to lower estrogen?
The recommended daily dose, ARIMIDEX 1 mg, reduced estradiol by approximately 70% within 24 hours and by approximately 80% after 14 days of daily dosing. Suppression of serum estradiol was maintained for up to 6 days after cessation of daily dosing with ARIMIDEX 1 mg.
What does an estrogen blocker do?
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.

In these other musculoskeletal tissues, estrogen improves muscle mass and strength, and increases the collagen content of connective tissues.
What’s the difference between testosterone and estrogen?
Relatively small quantities of testosterone are released into your bloodstream by the ovaries and adrenal glands.
