WHAT ARE AROMATASE INHIBITORS?

Aromatase Inhibitors (AIs) are a class of drugs commonly used for the treatment of breast cancer in women and gynecomastia in men. They have also been adopted by bodybuilders, who use these drugs off-label for the purpose of preventing excess estrogen levels during anabolic steroid cycles.

The term “estrogen blocker” is often referred to the AI drug class that we will dig into below.

  • AIs PREVENT AND REVERSE GYNECOMASTIA (GROWTH OF BREAST TISSUE IN MEN)
  • AIs HELP US MINIMIZE WATER RETENTION AND BLOATING
  • AIs PREVENT THE MOODINESS THAT COMES WITH HIGH ESTRADIOL

WHAT IS AROMATASE?

Aromatase 3d chemical structure

AIs work by inhibiting the aromatase enzyme. Aromatase, also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogen found in fat tissue and is responsible for the conversion (aromatization) of Testosterone into Estradiol (Estrogen).

HOW DO AROMATASE INHIBITORS WORK?

By inhibiting these enzymes, AIs allow bodybuilders to keep their estradiol levels under control during a Testosterone, Dianabol or Trestolone cycle. AIs are extremely useful for preventing the development of gyno (gynecomastia) and for reversing gyno during its early stages.

BENEFITS OF AROMATASE INHIBITORS

The benefits of AIs depend on how they are used and for what purpose. In a bodybuilding context, aromatase inhibitors allow us to use high doses of estrogenic Steroids like Testosterone and Dianabol without having to experience excessively high estradiol (estrogen) levels. By preventing excess estradiol levels, AIs have the following benefits:

  • AIs PREVENT AND REVERSE GYNECOMASTIA (GROWTH OF BREAST TISSUE IN MEN)
  • AIs HELP US MINIMIZE WATER RETENTION AND BLOATING
  • AIs PREVENT THE MOODINESS THAT COMES WITH HIGH ESTRADIOL
  • AIs IMPROVE SEXUAL FUNCTION

SIDE-EFFECTS OF AROMATASE INHIBITORS

Unfortunately, the useful properties of AIs come with some risks. If one overdoses AIs or is using them when the amount of Testosterone or Dianabol being employed is not very high, suffering from very low estrogen is a possibility. Besides that, most AIs tend to decrease good cholesterol and increase bad cholesterol.

These are the possible side-effects that AIs can cause by crashing estradiol levels if misused:

ARE AROMATASE INHIBITORS LEGAL?

The vast majority of AIs are classified as prescription medications. Fortunately, their patents have expired so their generic form can be legally bought and sold as “research chemicals” in the United States and other Western countries.

Research the legal status of Aromatase Inhibitors in your country before buying them online.

ARE AROMATASE INHIBITORS SAFE?

If we consider the aforementioned side-effects, it’s clear that AIs are not 100% safe. They can actually be quite harmful if misused, so be sure to do your own research and only use these drugs when strictly necessary.

AIs can be safe and extremely useful if used properly, so the general safety of using them comes down to the context in which they are being used.

WHICH AROMATASE INHIBITOR IS BEST WITH LEAST SIDE EFFECTS?

In short, none.

If we had to give the best option from empirical data we’ve received, Exemestane.

If you’ve read our other articles and aren’t new here, you’ll know it’s hard for us to give a straight-forward answer because most of the time, when dealing with research chemicals, there will almost always be something negative involved that must be taken into account. Keep reading to find out why the answer isn’t easy!

LIST OF AROMATASE INHIBITORS

Even though all AIs have a similar mechanism of action, we must make a distinction between two types of Aromatase Inhibitors: Suicidal Aromatase Inhibitors and Non-Steroidal Inhibitors. In the next paragraph we will explain the difference between them.

SUICIDAL AROMATASE INHIBITORS

These AIs (also known as Irreversible Steroidal Aromatase Inhibitors) work by permanently binding and deactivating the aromatase enzyme, causing the enzyme to “die”. In other words, Suicidal AIs cause the total amount of aromatase enzymes in the body to decrease. The most commonly used Suicidal AI by bodybuilder is Exemestane (Aromasin).

EXEMESTANE (AROMASIN)

PROS:

  • WILL PREVENT GYNECOMASTIA
  • WILL PREVENT HIGH ESTROGEN LEVELS DURING A STEROID CYCLE
  • WILL INCREASE TESTOSTERONE LEVELS TO A SMALL EXTENT

CONS:

  • MAY CRASH ESTROGEN LEVELS IF ABUSED

NON-STEROIDAL AROMATASE INHIBITORS

Non-Steroidal Aromatase Inhibitors work by blocking the aromatase enzyme and preventing Testosterone, Dianabol or other steroids from attaching to it. For all intents and purposes, these AIs do the same job as Suicidal AIs, but they simply deactivate the aromatase enzyme temporarily as opposed to destroying it. The most commonly used Non-Steroidal AIs are Anastrozole (Arimidex) and Letrozole (Femara).

Recently, these drugs have been considered over extremely popular SERMs like Tamoxifen for treatments like breast cancer. [R]

ANASTROZOLE (ARIMIDEX)

PROS:

  • WILL PREVENT GYNECOMASTIA
  • WILL PREVENT HIGH ESTROGEN LEVELS DURING A STEROID CYCLE
  • WILL INCREASE TESTOSTERONE LEVELS TO A SMALL EXTENT

CONS:

  • WILL CAUSE LOW HDL & HIGH LDL
  • MAY CRASH ESTROGEN LEVELS IF ABUSED

[R]

LETROZOLE (FEMARA)

PROS:

  • WILL PREVENT GYNECOMASTIA (BEST AI FOR GYNO)
  • WILL PREVENT HIGH ESTROGEN LEVELS DURING A STEROID CYCLE
  • WILL INCREASE TESTOSTERONE LEVELS TO A SMALL EXTENT

CONS:

  • WILL CAUSE LOW HDL & HIGH LDL
  • MAY CRASH ESTROGEN LEVELS EVEN AT LOW DOSES
