The Hyperspeed Potion is a non-limited common potion in Adopt Me! that can be found and purchased in the Sky Castle for 40 or brewed at home using a Speed Cauldron. The Speed Cauldron is 650 and produces 1 potion per minute.
The Hyperspeed Potion allows players to slightly increase their walk speed. This potion can be stacked; players can drink multiple potions to significantly increase their walk speed. The effects are permanent until you reset your character and/or leave the game. It is very similar to cotton candy and lollipops from the candy cannon, as all increase speed and can be stacked.
