No idea. IdealForehead said he will test the source, so I went with that just to make sure I have something from a verified source. I still have no idea what the f*** I'm putting on my head.
Either way, at a dose that actually works, the side effects in ethanol are screwed up. I will try putting it in liposomes tomorrow, maybe that helps somewhat. If not, we will have to move to S-Equol. The Brotzu lotion only uses like 7 mg per month, so shouldn't be too expensive. Though I have no idea how that dose can be effective when I need 20-30 mg per DAY to have an impact. Can the liposomes really make that much of a difference - I don't know.
