XL Candy in Pokémon Go serves as a crucial item for players looking to elevate their favorite Pokémon beyond the typical level 40 cap, pushing their Combat Power (CP) to a maximum of level 50. This advanced item is one of many collectible resources obtained through exploration and Pokémon capture within the game.
To power up a Pokémon to level 50 using XL Candy, trainers must use the specific XL Candy tied to that Pokémon's evolution line. For instance, boosting a Charizard's CP to its maximum requires Charmander XL Candy. This principle applies universally across all Pokémon species in the game.
The ability to acquire and use XL Candy becomes available once a player reaches Trainer Level 31. Following this unlock, there is a chance to earn a Pokémon's corresponding XL Candy each time that specific Pokémon is caught.
