well am looking to buy b-12 and stumbled upon this:B12 (Cyanocobalamin) USP 30 ml, 1000 mcg/ml for 8dollars, seems pretty fare, does anybody know how it is delivered, in one bottle or vials with one ml in each, if its a bottle how you gonna keep it clean?
and last: Can i inject in my thigh? i was thinking of shooting in thigh twice or more ew maybe complementing with some oral.
