Jack3d Blue Raspberry
Brand: USPlabs
Dr. Feb's Analysis
Scientific Mechanism
Jack3d functions primarily as a central nervous system stimulant via its Caffeine content (270 mg per serving). At the cellular level, caffeine acts as an adenosine receptor antagonist. By blocking adenosine, it prevents the onset of fatigue and reduces the perception of effort during exercise. This mechanism allows for increased neural drive and focus. The proprietary blend likely includes Beta-Alanine, which aids in buffering muscle acidity (lactate) during high-intensity anaerobic activity, potentially delaying muscular failure. The combination creates a synergistic effect: heightened arousal from caffeine and extended muscular endurance from pH buffering.
Key Benefits
Key benefits include:
- Enhanced mental focus and alertness prior to training
- Increased energy levels for high-intensity sessions
- Potential delay in muscular fatigue through lactic acid buffering
- Improved workout intensity and volume capacity
Usage & Safety
Mix one scoop (5.1g) with 6-8 oz of water. Consume 30-45 minutes prior to training. Do not exceed 2 scoops in a 24-hour period. Do not use more than 5 days in any 7-day period. Do not combine with alcohol or other stimulants (coffee, soda, other supplements). Avoid use under extreme heat, cardiovascular exertion, or dehydration.
