Dicaffeine Malate is actually a combination of caffeine and malic acid. Malic acid in turn is won out of Apple Juice and is a food additive with the E number E296. In green apples, the sour taste is due to malic acid. When cocaine was outlawed, The Coca-Cola Company introduced dicaffeine malate as the replacement. It is a stimulant, much like caffeine, but apparently gentler on the digestive tract. Many traits associated with regular caffeine are found in this caffeine salt, but through the interaction with malic acid, additional features have been observed. Dicaffeine malate is a very common ingredient in dietary supplements, it is supposed to optimize energy levels, increase mental focus and cognitive awareness, but also is able to stimulate thermogenesis.

Green Tea Extract- By increasing the body's metabolism, it is widely believed that green tea extract largely aids in weight loss.

Norphenephrine HCI is a chemical reactant compound that both plays as a hormone and at the same time as a neurotransmitter. It is normally combined in drugs that normally functions for the enhancement of memory and brain function. In addition to that, Norphenephrine HCI also acts as a kind of medicine or drug that is used to increase blood pressure. Take caution: this is not intended for people with high blood pressure levels. It increases the heart and pulse rate and that causes the increase in blood pressure. Basically, the body can normally produce enough Norphenephrine HCI, however, for some people who cannot cope up with the kind of Norphenephrine HCI that the system needs, a drug with this chemical composition is greatly needed.

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.

Synephrine or oxedrine is a drug derived from bitter orange or Citrus aurantium. It is an aromatic compound with the systematic name 4-[1-hydroxy-2-(methylamino)ethyl]phenol which indicates that it has an attached hydroxyl group at para position and a methyl amino group at another position. It is not one of those compounds on which an extensive scientific study has been done. However, it has some positional isomers such as the neosynephrine as well as other compounds. Studies indicate that it could act as a Beta-3 adrenergic receptor which means that if taken as a supplement it enhances the breakdown of fat to release energy and also increases heat production in the muscles.

Velvet Bean Extract is also called Macuna Prurien and is rich in an amino acid called L. Dopa which is precursor of dopamine, a neurotransmitter. It helps in improving coordination and sexual performance. It acts as an aphrodisiac and also aids in treatment of nervous system disorders, depression and mental alertness. Macuna Prurien also helps in maintaining the cholesterol and blood sugar levels. It also stimulates growth hormone and testosterone level that helps increase muscle mass and strength. It also helps in burning the fat for energy and turning it into lean muscles. It also has a diuretic effect that helps improve the muscle tissue resiliency.
