Prohormone & Supplement Ingredients:

6, 17-keto-etiocholeve-3-ol tetrahydropyranol

The first references I find to 6, 17-keto-etiocholeve-3-ol tetrahydropyranol indicate it was an ingredient in Nevedex Xtreme by Gaspari Nutrition.

According to that company's literature, 6, 17-keto-etiocholeve-3-ol tetrahydropyranol "is a patent-pending non-androgenic anti-aromatase that utilizes the advanced ether delivery technology. With its ether attachment, this amazing compound has a prolonged half life in the human body which means you only take it once per day as opposed to many times per day like other anti-estrogens."
