It works in the same way as certain drugs, the amphetamines, cocaine, and heroin, all of which work on the action of the brain although in a milder way, and like them it is addictive.

Methyl-Synephrine HCL- When ordinary synephrine failed to yield considerable effects on thermogenesis and body fat/weight loss, a new kind of synephrine namely "methyl synephrine" was developed to produce the desired effect. The scientists who developed this novel form of synephrine believe that the thermogenic effects of synephrine are increased manifold so as to facilitate greater fat/weight loss. In order to test its ability to serve as a potent lipolytic agent, it is important to test the new version of synephrine in controlled settings. Many people have expressed concern over the possible stimulatory effect of this supplement on the cardiovascular system, especially blood pressure and heart rate. To be on the safer side, make sure that you consult your doctor before taking methyl synephrine supplements or using it as a dietary supplement for weight loss.

Methylphenylethylamine Tartrate is compound formed by combination of Methylphenylethylamine with tartaric acid. This combination increases the stability of the compound. The compound is popular as an active ingredient in many weight loss supplements. It is used in weight loss supplements along with other ingredients, primarily because research shows that Methylphenylethylamine Tartrate suppresses appetite, thus helping the users to control their calorie intake. Some other research also claims that Methylphenylethylamine Tartrate directly helps in fat metabolism and also elevates energy levels. However, physicians suggest that dropping calorie intake below a safe limit may be dangerous to health.

N-Methyl-B-Pheylethylamine HCL is one of the various compounds got from Acacia Rigidula. It reduces fat in the body and increases the production of energy on a large scale. It is a fantastic compound that is a catecholamine precursor and even a nutrient available in chocolate even in its purest of forms. It produces simulation in the CNS (Central Nervous System) without giving rise to the jittery feelings or nervousness that occurs when some other drug is used. It acts on the alpha receptors present in the brain, resulting in release of the chemical, dopamine, which gives a good feeling. PEA is a compound that promotes focus, concentration and alertness of the mind. It can even elevate the metabolic rate of a person that causes increased fat burning. However, it is rapidly metabolized and crosses the blood-brain barrier in smaller proportions. This chemical is a potent wonder but, as with most chemical drugs, it is safe to take small and restricted measures just to be safe.

R-Beta-Methylphenylethylamine HCL is a relatively new compound which is the active isomer of Methylphenylethylamine similar to how 1R-25 Norephedrine was of PPA many years ago. What makes R-Beta-Methylphenylethylamine HCL very popular and an important component for many commercially produced weight loss products is to do with the effects it has on the human body. R-Beta-Methylphenylethylamine HCL is a compound which stimulates norepinephrine unlike any other compound in the body. By stimulating norepinehrine, R-Beta-Methylphenylethylamine HCL produces effects like appetite suppression, increase in energy and through the combination of these two effects, there is an overall result of weight loss.

Theobromine- The bitter alkaloid found in chocolate is known as theobromine. It comes from the cacoa plant and is found in chocolate as well as chocolate free foods that are consist of theobromine. Theobromine belongs to the methylxanthine class of chemical compounds. It is found in the leaves of the tea plant, the kola or cola nut and acai berries. No bromine is present in theobromine, despite the name. The properties of theobromine are that it is souluble in water, is crystalline, is a bitter powder, is listed as white or colorless in color. It is considered a lesser homologue because it has a lesser effect to caffeine. Theobromine is the kind of isomer which belongs to paraxanthine and theophylline at the same time. It is basically a xanthine having two methyl groups.
