This is from WebMD on the active ingredient:
Androstenetrione is a steroid . Despite serious safety concerns, it is used for improving athletic performance.
Androstenetrione is promoted as an alternative to "prohormones" such as androstenedione. Marketers claim that androstenetrione increases the body’s natural testosterone levels and therefore is free from the negative side effects of prohormones. There is no reliable evidence to back these claims.
How does it work?
The body converts some of the male hormone testosterone to the female hormone estrogen. Androstenetrione blocks this conversion. Some people suggest that the body makes up for the falling estrogen level by making more testosterone. They further suggest that the higher levels of testosterone will improve athletic performance. Some people who sell androstenetrione say that it increases total testosterone by 188% and free testosterone by 226% over 3 weeks of use. But there is no scientifically reliable research in people that supports these claims.
I trust their study references more than QuickGains.
They Claim: "These ingredients have been shown, in human clinical trials, to almost double testosterone, increase free testosterone (the testosterone level that is most important), decrease Sex Hormone Binding Globulin (SHRonin) (the compound that binds to testosterone to keep it in the unusable state), increase IGF-1 levels, and modulate cortisol levels. With this increase in both total and free testosterone, your strength and drive in the gym will follow, leading to superior lean muscle mass gains."
But they don’t site the source of this study.
Listen, if you’re actually considering buying this crap, I just happen to have some magic beans you may be interested in…
