What is an estrogen blocker?
Estrogen blockers are products/compounds that block the actions of estrogen. The most common estrogen blockers when it comes to the hardcore bodybuilding world are SERMs and Aromatase Inhibitors.
Why should I use an estrogen blocker?
As men, we are supposed to have estrogen, and our bodies naturally regulate our estrogen levels to keep it in proportion with our testosterone levels. If you are training hard, your body will naturally produce more testosterone, but unfortunately sometimes your body will convert some of that testosterone into estrogen.
If you are cycling prohomormones, taking an estrogen blocker becomes even more important. The reason for this is that when you are on a prohormone your body senses that your testosterone levels are high, regardless if it is natural testosterone or synthetic (prohormone). Your body naturally wants to keep your hormones balanced, so as a response to this your body will signal the release of an enzyme known as “Aromatase” which will convert testosterone to estrogen. Too much estrogen will lead to undesirable side effects like gynecomastia (gyno) and low sex drive.
Additionally, drinking alcohol can stimulate the production of estrogen, aside from the harshness on your liver, this is one of the major reasons why we strongly suggest that you do not drink alcohol during your cycle and PCT.
What is an aromatase inhibitor (AI)?
An aromatase inhibitor is a compound that binds itself to the aromatase enzyme and prevents it from converting androgens like testosterone into estrogen.
What is a Selective Estrogen Receptor Modulator (SERM)?
SERMs essentially regulate how your body handles estrogen, blocking some and allowing others.
