About this source

This review by Garage Gym Homie covers the David and Goliath Extreme pre-workout. The reviewer details its ingredient profile, including high dosages of L-citrulline, beta-alanine, caffeine, 2-aminoisoheptane, and alpha-yohimbine. He describes his personal experience with the product's onset time, energy levels, focus, and overall mood elevation during a workout.

Review notes

David and Goliath Extreme pre-workout is an exceptional choice for stim junkies, delivering an intensely aggressive euphoria and energy within minutes of consumption. The reviewer experienced immediate effects, noting energy, focus, and mood elevation kicking in within 3-5 minutes, even after eating. Its comprehensive stimulant profile, including 400mg caffeine, 250mg 2-aminoisoheptane, and 3mg alpha yohimbine, provides a potent, long-lasting buzz without a crash. The primary drawback is the potentially controversial alpha yohimbine, which some users might find too intense. If you crave immediate, powerful, and sustained stimulant effects for intense workouts, this pre-workout is definitely worth it. However, if you are sensitive to strong stimulants like alpha yohimbine or prefer a milder experience, you should consider other options.
