🔬 THE SCIENCE BEHIND THE SANDWICH

🏔️ Engineered for Extreme Survival - Not Just Calories. Precision.

📦 1 Sandwich = 8 Cubes = 1 Full Pizza Tray of Nutrition

Each 60g BUYA sandwich is composed of 8 precisely engineered cubes. Nutritionally, one sandwich equals a full pizza tray — and each individual cube delivers the satiety equivalent of one pizza slice. In the field, that means measurable, predictable, controlled fueling — no guesswork, no bonking, no waste.
