Pre-workout supplements are designed to give you energy and promote a better pump during your workout. They can contain a variety of ingredients, including:

• Stimulants: Caffeine, guarana, and beta-alanine help you feel awake and energized.
• Vasodilators: Arginine and citrulline help improve blood flow, delivering more oxygen and nutrients to your muscles.
• Creatine: Creatine helps muscles retain water and improves their ability to generate energy.
• Beta-Hydroxy-Beta-Methylbutyrate (HMB): HMB helps reduce muscle soreness and promotes recovery.
