i just assisted a friend in exchange for some tylenol w/codeine...he gave me 4, they're white and scored on on side with the numbers "94" and some other shit on the back, i'm sure they're legit, but does anyone know the standard going rate mg wise for these things? also, how will 4 down the gullet do a lad? i think i've taken 2 in the past and felt slight elation
