Alien Labs – Cold Chain Cartridge [1 g] XJ-13 is a premium 1 gram 510-thread cannabis vape cartridge from Alien Labs featuring the XJ-13 strain, a classic sativa-leaning hybrid derived from Jack Herer × G13 Haze known for its uplifting, creative, and euphoric effects with bright lemon, pine, and herbal notes in its flavor and aroma. This cartridge is part of Alien Labs’ Cold Chain formula, a craft extraction process that blends live and cured resin to preserve natural terpene and cannabinoid profiles by maintaining low temperatures through cultivation, extraction, and packaging — delivering rich, strain-true flavor and smooth, potent vapor.
