Hops has been the subject of a lot of serious study and
"
" Hops have been shown to contain one of the most potent in vitro estrogenic substance known from the plant kingdom, (±)-8-prenylnaringenin (Kitaoka et al., 1998; Milligan et al., 1999). "
As always, it is a matter of human biology whether it works for you or not. So much depends on metabolism and receptors. You probably need to try for a month to see if you have any reaction.
I've posted elsewhere about Asian women working with hops who all experienced breast growth--they were not doing NBE--and some people who drink ales and lager beers have experiencd growth.

The female flowers of the hop plant are used as a preservative and as a flavoring agent in beer. However, a recurring suggestion has been that hops have a powerful estrogenic activity and that beer may also be estrogenic. In this study, sensitive and specific in vitrobioassays for estrogens were used for an activity-guided fractionation of hops via selective solvent extraction and appropriate HPLC separation. We have identified a potent phytoestrogen in hops, 8-prenylnaringenin, which has an activity greater than other established plant estrogens. The estrogenic activity of this compound was reflected in its relative binding affinity to estrogen receptors from rat uteri. The presence of 8-prenylnaringenin in hops may provide an explanation for the accounts of menstrual disturbances in female hop workers. This phytoestrogen can also be detected in beer, but the levels are low and should not pose any cause for concern.
