7,8 Benzoflavone



Molecular Formula C19H12O2 
Molecular Weight 272.30 
CAS Registry Number 604-59-1 
EINECS 210-071-1



7,8 Benzoflavone is a synthetic flavone derivative, which is a potent aromatase inhibitor. It is known as alpha-naphthoflavone, and it shouldn’t be confused with 5,6 benzo, known as, beta-naphthoflavone, which is an inducer of detoxification enzymes and is not an aromatase inhibitor at all.


How it works


Aromatization is what occurs when testosterone converts to estrogen in the body. This is a big problem when athletes run many types of anabolic steroids, but also, it’s a problem with many over the counter supplements that boost testosterone. 7,8-Benzoflavone is an aromatase inhibitor, so it will help prevent aromatization, keeping your estrogen levels in check.


Use by Bodybuilders and Athletes


Anabolic steroids such, as dianabol, equipoise, deca durabolin, and testosterone, will convert into estrogen as they all aromatize. When a steroid user fails to control estrogen, a host of side effects will occur such as gynecomastia (bitch tits), water retention, insomnia, and organ strain. In addition, during post cycle therapy (PCT), many bodybuilders will experience a spike in estrogen, which will delay recovery of their natural testosterone levels. During this time, the athlete will lose motivation, muscle, and gain more fat.


It is very important that estrogen is kept in check during and after cycle; hence, you must use an aromatase inhibitor (AI). Benzoflavone will keep the estrogen from rising, and it is a mandatory addition to a supplement stack that boosts testosterone.
