Caffeine may be the most popular legal addictive stimulant that is available to mankind. Besides coffee, tea, guarana and kola nut have excess amount of this xanthine alkaloid, which is actually acting as a psychoactive drug. In several plants, caffeine is an effective insect repellant, but this trimethylxanthine is deemed by the Food and Drug Administration as generally safe food substance. It is an antagonist of adenosine receptors. The effect of caffeine is individual and may more or less increase the ability to perform physical and mental labor. It reduces the effects of fatigue and may in long term help predominantly men reduce the risk of developing Parkinson’s disease. It has also been observed that caffeine has nootropic effects, furthermore, regular consumption of caffeine may significantly reduce the risk of heart diseases.

Evodiamine- Tetradii Fructus, the fruit of the evodia plant, also known as Tetradium rutaecarpa, contains an active element that has recently been identified as evodiamine. This chemical compound is believed to be somewhat similar to capsaicin, the active compound found in the chili peppers. Some studies suggested that this vanilloid receptor agonist may interact with thermogenin, otherwise known as the uncoupling protein 1, UCP1, which is able to generate heat by a mechanism called thermogenesis. Tetradium rutaecarpa has been traditionally used in Chinese medicine for weight loss purposes and current studies seem to verify this information. Evodiamine has been embraced as a dietary supplement directed at weight loss, predominantly by the body building circles. This supplement is deemed to have energy burning and fat reducing, as well as diuretic properties.

Hordenine has antibacterial and antibiotic properties and is another weight loss agent that also stimulates the central nervous system.

L-Huperzine A is extracted from a Chinese herb called Huperzia Serrata. L-Huperzine A inhibits the breakdown of Acetylcholinesterase that aids in raising the level of Acetylcholine, a memory neurotransmitter. It also helps in strengthening the brain’s NMDA receptors (N-methyl D-aspartate) that enhances the communication between the brain cells resulting to enhanced concentration, focus, learning and other brain functions. L-Huperzine A also stimulates the synthesis of nerve growth factor that is responsible for maintaining and promoting youthful and healthy brain function. L-Huperzine A quickly and potently boosts the memory, learning and the concentration functions of the brain for a short period of time.

Methylaricaiden is an alkaloid that may be obtained from betel nut, the fruit of a palm tree. It is known to be a potent stimulant that improves the alertness, focus and concentration. It enhances the mood, and fights depression. It is also a mild laxative that helps prevent water retention, cleans the body, and aids in weight loss. It alleviates the symptoms of rheumatism and arthritis. It also helps treat headaches and fever. Methylarecaiden has prevents and kills parasites in the body. It also promotes wound healing. It also has antioxidant properties that scavenges free radicals and prevent it from causing cell damage.

Phenylethlamine HCL is a salt of phenylethylamine. It is a crystalline solid and is formed by treating phenylethylamine with HCl. Its IUPAC name is 2 phenylethylamine HCl. The scientific name elucidates its chemical structure. It is an aromatic compound meaning that it has a basic benzene ring. It further has a two carbon chain attached at position 2 of the ring and the chain terminates in an amino group. It occurs naturally in some foods like chocolates but the food item might get metabolized too quickly sometimes for it to have a significant effect on the body. This substance has quite profound effects on the level of dopamine in the central nervous system, provided it passes the blood brain barrier. It increases dopamine level and at the same time inhibits dopamine transmitters resulting in a buildup of dopamine in the brain. While excessive levels of dopamine in the CNS are not healthy, the neurotransmitter does regulate cognition, mood, voluntary movement and other brain functions.

Quercetin, a bioflavonoid derived mostly from blue-green algae. Quercetin is a strong antioxidant commonly found in onions, wine and tea.

Synephrine HCL is a stimulant that bares close similarities to caffeine, it aids in increasing metabolic rate as well as burning excess calories.
