Are aromatase inhibitors (in supplements) illegal for athletes and military personnel?

Universal Nutrition's Animal M-stak contains 5,7-Dihydroxyflavone and Kudzu Extract which are listed as aromatase inhibitors. I'm not exactly sure which agencies/authorities govern legality of these and other sports supplements. Any help appreciated before I try something out and pop on a urine test.

Are aromatase inhibitors (in supplements) illegal for athletes and military personnel?
Aromatase inhibition, the abstract concept, just prevents estrogens from being produced, it makes no claims as to how androgens and other hormones are effected.





For example, aromasin, a Rx only aromatase inhibitor by itself does not have androgen effects, a metabolite it is turned into does. Has it made it on the list, I do not know, but I see why it could make it on the list.





So, although I do not know the answer to this question, I can tell you that you should check first on what this particular inhibitor does in terms of androgens, second you should actually check with the olympic officials regarding a list of banned substances. It would be logical to assume that if it has androgenic effects it would be banned, but as the site listed below mentions sometimes supplements have ingredients not listed on the package which are banned.
