This potion causes the person consuming it to enlarge in both height and weight, his or her garments and other worn and carried gear likewise growing in size. 

Strength is increased sufficiently to allow bearing normal armor and weapons, but does not add to combat. 

Movement increases to that of a giant of approximately equal size. 

Each quarter of the potion consumed causes 6 ft. height growth, i.e. a full potion increases height by 24 ft.
