Where did you find out about the hormonal profile of pig placenta? Do you have any solid info about the hormones (or hormonal precursors) in BO? Do you know if the US requires that all glandulars be basically inert? I know that glandular thyroid supplements can't legally contain any actual animal thyroid hormones unless they're prescription. I don't know what the laws are regarding the other glandulars, but I'm gonna try to look into it.
