I don't know whether or not Siriporn is an extract, but I do know that St.Herb is an extract, while Ainterol capsules are not. Although, of course, Ainterol does sell extract in liquid form. No matter what the herb, you always have to consider whether it's in a concentrated form to figure out dosage. Of course, it would be a lot easier if we knew what the exact PM extract strengths are (meaning 5:1 or 10:1 etc.). It would be even better if they were standardized for miroestrol content. Right now it's like comparing apples to oranges.
