Hi mochaccino,
I wrote about miroestrol contents here

But I don't have data on St. Herb.
Check the link to puerariathai too: it's in Beverley's post above the one I linked above. Puerariathai charge more for spray dried PM powder. Spray dried PM is probably the raw material for the new Ainterol capsules too.
Spray drying is a process that dries faster than drying on a conveyor belt or in a kiln. Some PM literature says deoxymiroestrol is the active phyto-estrogen. Miroestrol is formed by air oxidation. I think they introduced spray drying to avoid oxidation of deoxymiroestrol to miroestrol. Oxidation, like other chemical reactions, is much faster at high temperature, so if the time at high temperature can be decreased, less oxidation products are formed.
So you need equal deoxymiroestrol levels, and the only way to get those is forum member reports on the relative strengths of different brands. You can check Ginie's and lled34aa's pages for comparisons of St. Herb with with Siriporn. St. Herb and Siriporn are comparable in strength on a 1 capsule = 1 capsule basis, but Siriporn capsules are smaller: 100 instead of 200 mg. To compare Siriporn with Ainterol (500 mg), Glittergirl and Nila and Rosance tried both.
