Glucuronolactone
Glucuronolactone has been clinically proven to reduce sleepiness and sleep-related driving incidents under conditions of afternoon monotonous driving following sleep restriction the night before. It is widely known to improve mental performance, reaction time, concentration and memory.   Glucuronolactone is useful for anyone wanting more energy, and is a popular way to boost exercise intensity and workout performance, or simply improve mood and alertness.  Glucuronolactone is found naturally in the body. It is most likely hepatoprotective, meaning it reduces ill effect or even improves the physical state and function of the liver, which is where the metabolism of glucose begins enzymatically.
Glucuronolactone (also known as D-glucurono-3, 6-lactone, or simply DGL) is an ergogenic aid that can help fuel both exercise performance and recovery

Some of the benefits also linked with Glucuronolactone include its effect as an aid to memory retention, concentration and reaction time. Glucuronolactone may also be helpful in ridding the body of harmful substances and providing an instant energy boost.

Phenylethylamine HCL
This amazing compound is probably the cleanest stimulant ever researched, and it is naturally present in human fluids and tissues. Although categorized as a stimulant, it has the remarkable ability to simulate the central nervous system without causing nervousness or the jittery feeling. Phenylethylamine is found in chocolate and is responsible for its effects on mood, appetite, and sense of well-being. Until recent discoveries, PEA, or phenylethylamine, was rapidly destroyed within the body. If included with novel delivery systems, phenylethylamine HCL is provided safe transport and this metabolic fate is avoided and pharmacological activity becomes extremely apparent. This catecholamine precursor is responsible for elevating the metabolic rate and promoting a sense of satiety. Phenylethylamine acts on alpha-receptors in the brain, as do norepinephrine and certain prescription anti-obesity drugs. It is also believed to cause the release of dopamine in the pleasure sensing areas of the brain. Phenylethylamine HCL has a close chemical relationship to pharmaceutical stimulants, because it is the backbone of many pharmaceutical compounds.

Yohimbine HCL
Yohimbine has been found to increase lipolysis by increasing the release of norepinephrine available to fat cells and blocking alpha-2 receptor activation. Yohimbine HCL ha also been known to increase energy levels causing increase heart rate and vasodilation.

1, 3 Dimethylamylamine
DMAA is a more powerful stimulant than caffeine. This means that a smaller amount of DMAA is required to experience more profound stimulant effects. DMAA benefits include elevated mood, energy, and confidence. DMAA takes longer than caffeine to take effect, about 45 minutes, but the effect lasts up to 5 hours.

Caffeine
Caffeine acts as a central nervous system (CNS) stimulant, temporarily warding off drowsiness and restoring alertness. Caffeine generally takes effect 5- 15 minutes after ingestion.
