It's odd he'd say they don't know about the megadosing, when the company rep was in this thread when I was discussing it, and he interacted with some of those posts. And they modified the website to include the bulk discounts directly after discussing it with me, and yes, I was discussing mega-dosing in the same post I asked them offer bulk discounts, and I discussed it in a PM with the company rep. So, if Gee is being truthful that they said they don't know whats up with the mega-dosing, they are being dishonest.
Frankly what the levels of Daidzein in the Japanese population at large are aren't hugely relevant to which dose of equol itself is necessary to halt androgenetic alopecia. While the DHT levels have been found less than Americans, they were higher than New Zealanders in at least one study. I believe there is a dose of equol which should halt male pattern baldness. We don't know what it is. Folexen doesn't know what it is. Nobody knows what it is. Maybe long term their dose does it, maybe it doesn't. They are likely pushing the low dose due to cost reasons. If the promoted dose was higher they (1) wouldnt profit and (2) if they increased the price to still profit, then price would star getting prohibitive and fewer would buy it, and, well, see (1)
