What are some benefits and side- effects of anti-estrogen/anti-aromatase as a nutritional supplement?

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

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

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

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

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
