Bucked Up Mother Bucker
Mother Bucker is Bucked Up's strongest pre-workout, and the front of the tub says so: "WARNING HIGH-STIMULANT." One scoop has 400 mg of caffeine (300 mg regular plus 100 mg delayed-release), 6,400 mg of beta-alanine, 4,000 mg of L-citrulline, 1,500 mg each of Nitrosigine and L-tyrosine, 500 mg of HydroPrime glycerol, 300 mg of alpha GPC, theobromine, rauwolscine and huperzine A.
Every amount is on the label. The doses haven't changed since it launched in 2023, even as the tubs got new art. Each tub has 20 servings, and we carry Rocket Pop, Gym Junkie Juice, Strawberry Super Sets, Musclehead Mango, Miami, Muscle Melon, Blackberry Lemonade and Dragon Fruit Lemonade.
