Trendione

Trendione (developmental code name RU-2065; nickname Trenavar), also known as estra-4,9,11-triene-3,17-dione, is an androgen prohormone as well as metabolite of the anabolic steroid trenbolone.[1][2][3][4][5] Trendione is to trenbolone as androstenedione is to testosterone.[6] The compound is inactive itself, showing more than 100-fold lower affinity for the androgen and progesterone receptors than trenbolone.[7][8] It is a designer steroid and has been sold on the internet as a "nutritional supplement".[1] Trendione is listed in the United States Designer Anabolic Steroid Control Act of 2014.[1]
