Q&A Section
Q: What makes Doomsday different from other pre-workouts?
A: It combines multiple stimulants including DMHA, DMBA, and two forms of caffeine, alongside nootropics and thermogenics, making it one of the most comprehensive and intense pre-workouts on the market.

Q: How much caffeine is in Doomsday?
A: It contains 350mg of Caffeine Anhydrous plus additional caffeine from 100mg of Guarana Extract, totaling over 370mg of caffeine per scoop.

Q: What does GBB do in this formula?
A: GBB (Gamma-Butyrobetaine) is a precursor to L-carnitine that can increase thermogenesis, leading to a warming sensation and supporting fat burning during training.

Q: Can beginners use this pre-workout?
A: No—Doomsday is formulated for advanced users only due to its potent stimulant profile. Beginners should start with a milder pre-workout.

Q: How should I take it?
A: Mix 1 scoop with 10-12 oz of cold water and consume 20–30 minutes before training. Start with half a scoop to assess tolerance.
