The Zamorak potion is a potion that increases Strength by 10 levels, Attack by 5 levels, and doubles your max hit. The boosts will stay for 5 minutes and then drop by 1 level per minute. The Zamorak potion comes in 4 doses. This potion can also be made at 95 Herblore. This potion cannot be used with the Saradomin potion. Because of this potion, people stopped buying strength potions and super strength potions. Thus their prices dropped dramatically. Since it could sometimes take lots of waiting to get the potion, smart people bought strength potions.
