Estrogen is a category of sex hormone responsible for the development and regulation of the female reproductive system aswell as secondary sex characteristics. Men naturally produce estrogen, but it is critical for men to maintain a healthy balance between estrogen and testosterone to maximize gains. Most men reach peak testosterone production between the ages of 25-30 and will experience a gradual decline from ages 30-40. 

There is a direct relationship between high levels of estrogen and free testosterone levels. Taking a supplement like one of our estrogen blockers can work to inhibit excessive levels of estrogen which usually leads to enhanced free testosterone levels. Estrogen blockers prevent estrogens like estradiol from mediating their biological effects in the body. They act by blocking the estrogen receptor and/or inhibiting or suppressing estrogen production.

Estrogen blockers can be used as a standalone product, during a pro-hormone cycle, or as a component of post-cycle-therapy. They can support estrogen modulation, free testosterone enhancement, and an optimal testosterone to estrogen ratio.

One type of estrogen blocker we carry are called suicide aromatase inhibitors (AI's). They permanently bind to the aromatase enzyme and prevent any estrogen rebound. They can reduce cortisol, raise luteinizing hormone, and increase testosterone levels. It is highly recommended that anyone who takes a pro-hormone incorporates some form of estrogen blocker into their post-cycle-therapy to avoid entering in a state of estrogen dominance.
