im thinking about trying this out. if someone could give me some advice on this. i am currently 185 and inject b-12 every 3 days at 1ml. i noticed this has b-12 in it as well, does anyone know how much so i can figure how much b-12 i need to cut down on my other shots?? i am trying to figure this out so maybe 3-3.5ml. of syntheselen daily?? but should i keep on taking my sythetek b-12 like normal, because maybe syntheselen doesnt have alot of b-12 and since its only cyanacobalamin?
