Arimistane (Androsta-3 5-diene-7 17-dione) is an Aromatase Inhibitor (AI), a metabolite of 7-Keta DHEA. According to some studies, this product is effective in reducing estrogen (estradiol) levels. That’s why, people use Arimistane sometimes as a form of Post Cycle Therapy (PCT), or for controlling estrogen levels when they are likely to increase.

Arimistane is mostly present in form of capsules. Nevertheless, some companies might offer it in liquid form.

Arimistane actually occurs in the human body naturally. Some researchers suggest that Arimistane (Androsta-3 5-diene-7 17-dione) is actually one of the best AIs out there. Since it lowers estrogen levels by binding to aromatase enzymes and disabling them, you can use it for:

  • Post Cycle Therapy (PCT)
  • Preventing estrogenic issues
  • Treating gynecomastia (and other estrogen related problems)

Moreover, Arimistane is an Aromatase Inhibitor (AI) that is similar to Aromasin (Exemestane) in terms of permanently binding to aromatase enzymes and disabling them. That’s great at reducing the risks of estrogen rebound.

Moreover, studies indicate that Arimistane is helpful at reducing cortisol, raising Luteinizing Hormone (LH), and increasing testosterone levels. That’s all extremely helpful for bodybuilding and fitness purposes.

It has no medical purposes so far, but since it’s a powerful irreversible aromatase inhibitor (AI) that suppresses estrogen biosynthesis – it might become a popular medication one day. Androsta-3 5-diene-7 17-dione (ATD) lowers estrogen by permanently binding and inactivating aromatase in the adipose and the peripheral tissues. Many consider it a very effective compound when it comes to controlling the synthesis of estrogen.
