BPI Sports 1MR OG is the pre-workout that started it all — a legendary, hard-hitting formula built for lifters who remember why pre-workout exists in the first place: to make you feel unstoppable. This classic recipe delivers explosive energy, laser focus, and skin-tearing pumps designed to push you through your heaviest sessions.
With a potent blend of stimulants and pump-driving actives, 1MR OG hits fast and holds strong, giving you the kind of intensity that turns an average workout into a personal record. Available in Blue Raspberry, Fruit Punch, and Sour Gummy, it's a throwback formula with the same aggressive edge that made it a gym-bag staple.
