The Red-Heisen 500ml E-Liquid by The Juice Lab is a large-bottle e-liquid known for its complex and bold flavor profile. It’s likely inspired by classic "Heisenberg" e-liquids, which are usually a mix of fruity and menthol flavors with a hint of aniseed, but the "Red" twist might introduce notes of berries or other red fruits.

This large 500ml bottle is designed for users who want a long-lasting supply. Given the size, it may come in a high-nicotine base or even in zero-nicotine to allow users to add their preferred nicotine shots, especially if it’s labeled as a "shortfill" (leaving room in the bottle for adding nicotine).

The Juice Lab brand is known for crafting quality, lab-tested e-liquids, often with complex flavor combinations.
