Pre-Workout & Fat Burners
Pre-workout and fat burner supplements for athletes and gym-goers who want more energy, focus, and endurance going into a training session.
What to Look For
- Caffeine dose: Most stimulant pre-workouts contain 150–350mg caffeine per serving. Match the dose to your tolerance and avoid taking within 6 hours of sleep.
- Stim vs. stim-free: Stimulant formulas use caffeine for energy; stim-free formulas use pump ingredients like citrulline and nitrates for blood flow without the crash.
- Key actives: Look for L-Citrulline (2–6g) for pumps, Beta-Alanine for endurance, and Alpha-GPC or L-Theanine for focus alongside caffeine.
Frequently Asked Questions
What is the difference between stimulant and stim-free pre-workout?
Stimulant pre-workouts contain caffeine and other stimulants to boost energy and mental focus. Stim-free versions use pump and performance ingredients like citrulline, betaine, and nitrates to improve blood flow and endurance without affecting your heart rate or sleep.
How much caffeine is too much in a pre-workout?
Most people tolerate up to 200mg of caffeine per serving without side effects. High-stim formulas can contain 300–400mg — these are best for experienced users who have built up a tolerance. If you are new to pre-workout, start with a half serving to check your response.
When should I take pre-workout?
Take pre-workout 20–30 minutes before training for most powder formulas. Avoid taking stimulant pre-workouts within 6 hours of your planned bedtime to prevent sleep disruption.
