Pre-workout supplements are one of the most marketed โ and most misrepresented โ categories in sports nutrition. Most products are underdosed, rely on proprietary blends to hide their ingredients, or dump excessive stimulants to create an artificial "feeling" of effectiveness.
We compared 12 pre-workouts on disclosed dosing, proprietary-blend use and price per serving. We scored energy levels, pump quality, mental focus, side effects and the inevitable crash. Here are our findings.

Pre-Workout Buying Guide
Key Ingredients to Look For
- L-Citrulline (6-8g): Increases nitric oxide for better pumps and blood flow
- Beta-Alanine (3.2g): Buffers lactic acid for improved endurance (causes harmless tingling)
- Caffeine (150-300mg): Energy and focus. Avoid products exceeding 300mg
- Betaine Anhydrous (2.5g): Power output and body composition support
- Alpha-GPC (300mg): Focus and mind-muscle connection
Red Flags to Avoid
- Proprietary blends: If you can't see exact doses, move on
- Excessive caffeine (400mg+): Short-term energy, long-term adrenal fatigue
- Artificial sweeteners in high amounts: Can cause GI distress
- Pixie-dusting: Ingredients listed but below effective doses
