Arimistane or Androst-3,5-DIEN-7,17-DIONE is an powerful legal aromatase inhibitor which otherwise known as a estrogen blocker. To make it clear, it is also known as the following chemical names : Androst 3,5-dien-7,17-dione, 3-deoxy-7-oxo-DHEA, 7 Keto DHEA.

This product replaced an aromatase inhibitor called ATD (1,4,6-Androstatrien-3,17-dione) that was banned a few years ago. This new AI is so strong that some people even compare it to several over the counter estrogen blockers.


This product can be taken in several different ways, either for an over the counter post cycle therapy or on its own for people with high estrogen levels. Taking as a PCT, we recommend going with 75 mg daily for the first week, then go with two weeks at 50 mg daily and finish with one week at 25 mg daily. You can bump that dosage of 25mg for each week for an harsh cycle.
