• Intense Workout Energy: Delivers 350 mg of caffeine anhydrous to help increase wakefulness, alertness, and perceived energy during demanding training sessions. The stimulant content is substantial and best suited to caffeine-tolerant adults.
• Muscle Pumps & Blood Flow: L-Citrulline serves as a precursor to arginine, which the body uses to produce nitric oxide. This pathway supports normal blood vessel relaxation and circulation and may contribute to the muscle pump experienced during resistance training.*
• Muscular Endurance: Beta-Alanine supports the formation of carnosine in skeletal muscle. Carnosine contributes to intracellular buffering during intense exercise, helping support performance during repeated or sustained high-intensity efforts.*
• Strength & Power Support: Betaine Anhydrous participates in cellular osmotic regulation and methyl-group metabolism. Research has investigated its potential effects on muscular power, training volume, and body composition, with mixed results.*
• Training Fuel: The Glycogen Polymers blend provides carbohydrates from dextrose, Cluster Dextrin™, and D-ribose to complement energy availability during physical activity.
• Focus & Mental Alertness: Alpha-GPC, CognatiQ® Coffee Fruit Extract, caffeine, and other botanical compounds are included to complement the formula's cognitive-performance positioning. Specific cognitive improvements from the finished formula have not been established.*
• Muscle Function & Hydration: Taurine, sodium, and chloride contribute compounds involved in normal cellular fluid balance, muscle function, and electrolyte regulation.*
• Botanical Performance Support: Panax ginseng and wild blueberry extract contribute naturally occurring plant compounds studied for potential antioxidant, cognitive, and exercise-related biological activities.*

• L-Citrulline — 5,000 mg: A nonessential amino acid that can be converted into arginine in the body. Arginine serves as a substrate for nitric oxide production, supporting normal vascular function and blood flow. Citrulline supplementation has been studied for its potential effects on exercise performance and resistance-training muscle pumps.*
• Beta-Alanine — 5,000 mg: An amino acid that serves as a precursor for carnosine synthesis in skeletal muscle. Increasing muscle carnosine through consistent supplementation can improve buffering capacity during high-intensity exercise. Temporary skin tingling, called paresthesia, is a common dose-related effect of Beta-Alanine.
• Glycogen Polymers — 5,000 mg: A carbohydrate blend containing dextrose, Cluster Dextrin™ (Highly Branched Cyclic Dextrin), and D-ribose. These ingredients provide carbohydrate substrates associated with energy metabolism. The label does not disclose the individual amount of each component.
• Betaine Anhydrous (Trimethylglycine) — 1,500 mg: A naturally occurring compound involved in methyl-group metabolism and cellular osmotic regulation. Betaine has been studied for potential benefits involving muscular endurance, power output, and training adaptations, although findings vary.*
• Taurine — 750 mg: A naturally occurring amino sulfonic acid involved in cellular osmoregulation, calcium handling, and normal muscle and nervous-system function. Taurine is commonly included in sports nutrition formulas for its potential contributions to exercise-related physiological processes.*
• Caffeine Anhydrous — 350 mg: A concentrated form of caffeine that stimulates the central nervous system primarily through adenosine receptor antagonism. Caffeine can improve alertness, reduce perceived fatigue, and support certain measures of exercise performance. This is a high amount for a single serving and may cause unwanted stimulant effects in sensitive individuals.
• Alpha-GPC (L-Alpha-Glycerylphosphorylcholine) — 250 mg: A choline-containing compound that supplies a precursor used in acetylcholine synthesis. Acetylcholine is involved in normal nervous-system signaling, attention, and neuromuscular activity. Research on Alpha-GPC supplementation for improvements in cognition and exercise performance remains limited.*
• CognatiQ® Coffee (Coffea arabica) Fruit Extract — 150 mg: A branded coffee-fruit extract containing naturally occurring plant compounds. Coffee fruit extracts have been investigated for potential cognitive and neurological applications, but results from specific research formulations cannot automatically be applied to this complete pre-workout product.*
• Panax Ginseng (Panax ginseng) Stem & Leaf Extract — 75 mg: A botanical extract standardized to 7% ginsenosides. Ginsenosides are characteristic compounds of Panax ginseng, traditionally used for vitality and studied for possible effects on fatigue, cognitive performance, and physiological stress responses.*
• Theobromine — 50 mg: A naturally occurring methylxanthine found in cacao. Theobromine is chemically related to caffeine and has milder stimulant properties. It may contribute to the formula's overall stimulant effects.
• AuroraBlue® Wild Blueberry (Vaccinium spp.) Fruit Extract — 50 mg: A branded wild blueberry extract containing naturally occurring polyphenols. Blueberry phytochemicals, including anthocyanins, have been investigated for antioxidant and cognitive-related biological activities.*
• Sodium — 250 mg & Chloride — 380 mg: Essential electrolytes provided from sodium chloride. They participate in normal fluid balance, nerve signaling, and muscle function.

AFTERDARK InHuman Tropical Nightmare combines ingredients targeting several complementary aspects of exercise performance. L-Citrulline is converted into arginine, which the body uses to produce nitric oxide, a signaling molecule involved in vascular relaxation and normal blood flow. Beta-Alanine contributes to the production of muscle carnosine, which helps buffer changes in intracellular acidity associated with demanding exercise. Because muscle carnosine accumulates with repeated supplementation, the established performance benefits of Beta-Alanine generally depend on consistent intake rather than a single pre-workout serving. The Glycogen Polymers blend supplies carbohydrates from dextrose, Cluster Dextrin™, and D-ribose, while Betaine Anhydrous and taurine contribute compounds involved in cellular regulation and energy-related processes. For immediate stimulant effects, 350 mg of caffeine anhydrous acts primarily by blocking adenosine receptors, increasing alertness and potentially reducing perceived exertion. Alpha-GPC supplies choline for acetylcholine synthesis, while CognatiQ® Coffee Fruit Extract, Panax ginseng, theobromine, and AuroraBlue® Wild Blueberry Extract round out the formula's cognitive and botanical profile. Together, these ingredients create a high-stimulant pre-workout designed to support energy, focus, muscle pumps, and training performance. Individual results vary, and the combined formula has not been established to produce specific increases in muscle growth, strength, or cognitive function.*

• High-Dose Performance Formula: Combines 5 g each of L-Citrulline and Beta-Alanine in one full serving.
• Multi-Source Carbohydrate Blend: Includes dextrose, Cluster Dextrin™, and D-ribose rather than relying on a single carbohydrate ingredient.
