A stack is two or more Magnum formulas designed to be taken together, priced lower than buying them one at a time. The Hydration Stack pairs electrolytes with daily greens for people who train in heat or sweat through long sessions. Every product inside a stack carries a fully disclosed Supplement Facts panel and no proprietary blends. More stacks are added as they launch. If you would rather assemble your own, browse the full range and combine the formulas that match your goal.
