Estrogen is often an unwanted by-product of a prohormone cycle. Excess estrogen in males can trick the body into many female like features and functions, this condition is called gynecomastia. In severe cases the condition can require treatment and surgery. Our estrogen blockers can help prevent gynecomastia so it is wise to consider them as part of your prohormone cycle.

Estrogen Blocker Info
What are Estrogen Blockers?
Estrogen blockers, also called eblockers and estro blockers are created to assist in lowering estradiol which is a female hormone that can cause numerous issues when levels are too high in men.
These issues can include development of female breast tissue, increased fat storage, excess water retention, and decreased libido.
By lowering estrogen and optimizing your levels of free testosterone, you will be able to avoid or reduce the appearance of gynecomastia, reduce fat storage, reduce water retention, and help improve your sex drive.
How long can I use an Estrogen Blocker for?
Most estrogen blockers are used for a period of 6 weeks max as this is usually where the returns begin to diminish.
What is the difference between an Estrogen Blocker and an Aromatase Inhibitor (A.I.)?
Estrogen blockers help lower circulating levels of estrogen and/or prevent estrogen from binding to breast tissue receptors. Such Select Estrogen Receptor Modulators (SERMs) or Estrogen Blockers are best used during Post Cycle Therapy (PCT) or after completion of an AAS (anabolic-androgenic steroid) cycle.
Aromatase inhibitors help by optimizing free testosterone levels by preventing testosterone from converting into estrogen. Aromatase Inhibitors (AIs) are commonly only used during a PH or AAS cycle to help prevent estrogen build up, gyno flare-up, and to prevent excess water retention from compounds that have a high estrogen conversion rate.
In summary, Aromatase Inhibitors are mainly taken during a prohormone cycle while E-Blockers/SERMS are primarily used during a Post Cycle Therapy.
Which ingredients are most effective?
Arimistane - Arimistane is one of today’s most well regarded "aromatase inhibitors." Aromatase is the enzyme that causes testosterone to convert into estrogen, as an inhibitor of aromatase, Arimistane binds to the aromatase enzyme and helps prevent it from converting your precious testosterone into estrogen. This prevents the build up of excess estrogen and also results in overall higher testosterone levels, as by preventing the conversion to estrogen, your body's testosterone levels remain higher. Additionally, Arimistane can help reduce cortisol, which is a stress hormone that actually causes muscles to catabolize and body fat to increase. Arimistane does an amazing job in helping increase muscle hardness and reducing body fat and water retention.
Atractylodes Macrocephala - In studies, this ingredient has been exceptionally strong with 94.5% aromatase inhibition. Additionally, unlike many of the aromatase inhibitors on the market Atractylodes Macrocephala has shown to have exceptional oral bioavailability. In animal studies, subjects experienced 20% more growth when compared to the placebo group which was attributed to increases in growth hormone of 30%, IGF-1 of 52%, T3 of 47%, T4 of 36%, and cAMP of 21%.
Dehydroabietic Acid (DHAA) - Studies suggest that this powerful ingredient has an anti-estrogen effects. It also boosts the production of adiponectin, a protein hormone that helps supports weight loss. As a matter of fact, lowered levels of adiponectin correlate with obesity. Therefore, this ingredient may help enhance body composition while helping decrease estrogen.
