Marty, I recently found information on a nasal spray of Cyanocobalamin called Nascobal from Questcor. General web site <A HREF="http://www.nascobal.com/index.html" target="_blank">http://www.nascobal.com/index.html</A> Prescribing info <A HREF="http://www.nascobal.com/prescr_info.html" target="_blank">http://www.nascobal.com/prescr_info.html</A> Is there any potential there for a competitive product? Thanks in advance. ScaryStocks
