-
- L-citrulline: Research shows it boosts nitric oxide, improving blood flow to muscles for better exercise performance and reduced fatigue. A 10-gram dose is optimal for maximizing benefits.
- Glycerol: Enhances muscle pump by increasing fluid retention and muscle volumization, improving muscle fullness and pump intensity.
- Agmatine sulfate: Increases nitric oxide production, improving blood flow during training for a better muscle pump and workout performance. It may also offer benefits for pain resistance.
- Theobromine: Found in cocoa beans, it boosts exercise pump by increasing blood flow to muscles through vasodilation.
-
- L-tyrosine: Boosts mood and focus by influencing dopamine and norepinephrine levels in the brain. Taking 5 grams can support cognitive function during weightlifting.
- Alpha-GPC: Contains choline, a precursor to acetylcholine, which is important for memory and learning. Doses around 600mg have shown improvements in reaction time, memory, and physical performance.
- L-theanine: Found in tea leaves, it enhances attention, focus, and reaction time. It also helps counteract caffeine's negative effects like jitteriness and anxiety, while preserving caffeine's mental benefits.
-
- Caffeine: Increases energy, endurance, strength, and focus during weightlifting. 200mg is a common effective dose that provides a moderate boost without causing jitteriness or sleep disruptions.
- Infinergy: Contains malic acid to slow caffeine absorption, providing a more gradual and sustained release of energy. Combining 200mg of caffeine with 50mg of di-caffeine malate can enhance energy and focus during weightlifting while reducing energy crashes.
- Theobromine: Found in cocoa beans, it offers mild stimulant effects like caffeine, boosting alertness, energy, and mood during workouts. It also promotes better blood flow to muscles, aiding recovery and supporting overall exercise performance.
