Caffeine is a stimulant drug used for mental alertness and to accelerate energy and power. It is also used to delay muscle fatigue as it goes deep into the muscle tissues.

L-Tyrosine is a proteinogenic polar amino acid, deemed not essential because it can be synthesized by the human body. As a member of the amino acid group that is being used by cells to build proteins, this building block derived its name from the Greek word tyros, which means cheese, because it was discovered in the cheese protein casein. L-Tyrosine can be synthesized from phenylalanine and can be found in foods high on protein, like soy products, poultry, cheese, bananas, dairy products and several seeds, including the sesame seeds. The unique phenol functionality and the occurrence in proteins that belong to the signal transduction process, make this amino acid different.

Methylsynephrine basically produces central nervous stimulation and this is why it is used in Benzedrine. Methylsynephrine is one of the newly identified key alkaloids in Acacia Rigidula. Methylsynephrine is an off the chain version of Synephrine. It is an adrenergic amine which accelerates fat metabolism as well as thermogenisis. These simultaneously speed up the fat burning process. Methylsynephrine, unlike ephedrine which is chemically similar, has mild stimulating properties on the central nervous system. This is a very desirable property in any weight loss compound as it allows for quick fat burning without the accompanying racing hear and anxiety. Methylsynephrine is also distinctive due to its role in the metabolization and the destruction of fat in the body by freeing up the stored fat for energy instead of using the ingested carbohydrates.

N-Methyl-B-Phenylethylamine is an extremely important derivative used in fat loss. It also appears as Beta-Phenylethyylamine (PEA). As a catecholamine antecedent and nutrient in chocolate, it acts a stimulant to the central nervous system without side effects like nervousness or jitteriness that is almost normal with stimulants.

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.

Synephrine HCL is used in traditional Chinese medicine for various purposes such as appetite suppression and fat loss. Synephrine HCL is associated with ephedrine and ephedra and this is the reason that they get focused energy. It is as well noted that the users do not have a feeling of their energy getting crashed.
