Snorting it would NOT bypass the liver, and neither does a patch. The only topical application that would potentially bypass the liver (and then, not even completely) would be a cream applied directly on the breast with the idea being the phytoestrogens are absorbed directly by the tissue that is being affected. Anything that enters the blood stream, WILL pass through the liver, no exceptions. Snorting any substance puts it in contact with the numerous capillaries in the nose with idea being that the substance enters the blood stream faster than by ingestion. Thus, it will pass through the liver.
Hope this helps,
