Blocking aromatase causes the body to decrease in levels of estradiol, which then results in increase of ] and consequently, ]. Since testosterone has myotropic activity and estradiol does not, elevated testosterone levels increase muscle mass. However, there appear to be no human or animal studies testing the hypothesis that 4-AT will produce an anabolic effect. |

4-AT is used by ] or ] users to counteract ] level increases caused by aromatization during their ]. This helps minimize side effects such as ] but can lead to ]. Also, after a steroid cycle, the compound may be used to shorten the recovery from the testicular suppression that can be the result of the use of steroids. |

Baylor University conducted an eight-week study to determine the effects of 300 mg or 600 mg of 4-AT in resistance-trained males. Compared to baseline, free testosterone increased by 90% for 300 mg group and 84% for 600 mg group, respectively. Also ] and the ratio of ] to ] increased significantly. The report concluded that "he results of this study indicate that eight weeks of 6-OXO supplementation had no effect on body composition or clinical safety markers, but incompletely inhibited aromatase activity and significantly increased endogenous DHT levels that were attenuated after a three-week washout period".<ref name="Rohle2007">{{cite journal | vauthors = Rohle D, Wilborn C, Taylor L, Mulligan C, Kreider R, Willoughby D | title = Effects of eight weeks of an alleged aromatase inhibiting nutritional supplement 6-OXO (androst-4-ene-3,6,17-trione) on serum hormone profiles and clinical safety markers in resistance-trained, eugonadal males | journal = Journal of the International Society of Sports Nutrition | volume = 4 | pages = 13 | date = October 2007 | pmid = 17949492 | pmc = 2100070 | doi = 10.1186/1550-2783-4-13 | doi-access = free }}</ref> This study did not utilize a control group and was funded in part by two producers of commercial 4-AT.<ref name="Rohle2007" /> |

In a ]{{Citation needed|date=June 2009}} dated July 7, 2006, the ] (FDA) argues that marketing of 4-AT violates the Federal Food, Drug, and Cosmetic Act and as such products containing it are ''adulterated'' by legal definition. |
