there was a guy on the old "other" web site who used to experiment with taking different forms and doses of b12 and would post his results with himself and his family. Dibencozide (adenosylcobalamin) was one of those. He was from Utah i think but i dont remember his name. I havent seen him around in a long time. Its a shame but im pretty sure that you wont be able to search for this because all of their archives are on ice.
