Caffeine- The bitter, white crystalline xanthine alkaloid caffeine is found in tea, coffee, soft drinks, chocolates, pain relievers, and a variety of over the counter medications. It is a psychoactive stimulant drug that causes increased alertness by stimulating the central nervous system. For the same reason, many people feel more energetic after consuming it. It even elevates the mood but these effects do not last for long. The effects of caffeine usually last for about five to six hours, though caffeine sensitivity varies from person to person. It has been found that people who consume lot of caffeine on a daily basis soon develop less sensitivity and may need to increase their intake to enjoy the same effect. Being a diuretic, a person consuming caffeine may have to urinate more often.

Guarana Extract is the extract of the guarana plant. It contains a significant amount of guaranine, a substance that is similar to caffeine found in coffee beans. It helps stimulate the adrenal glands and increase the production and release of hormones such as epinephrine, norepinephrine (adrenaline), and dopamine. This helps the metabolism of the body that enhances fat loss, and increases energy and endurance. It helps the body burn the fats to be used for energy. It aids in fighting stress, weakness and fatigue. As a stimulant, it also improves mental alertness, clarity, focus, concentration, and memory retention. Guarana also also improves the libido or sex drive in both men and women. Guarana also contains tannins that help prevent diarrhea and soothes the digestive system.

Methylsynephrine is a variation of B – phenylehylamine which is found in the rare medicinal plant Acacia Rigidula and some other cacti which basically produces central nervous stimulation. 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.

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.

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- Designed primarily to encourage fat loss. This is achieved by stimulating the beta-3 receptors. Doing so increases the metabolic rate leading to fat loss. Synephrine is a stimulant similar to caffeine and ephedrine and it is believed to provide an energy boost, suppress appetite and increase metabolism. The combination of all leads to burning more calories. Studies have stated that synephrine stimulates fat metabolism without the usual negative cardiovascular side effects. The effectiveness of synephrine is increased by combining it with HCL. This allows for increased absorption and more solubility in water. However regardless of the increasing popularity of synephrine HCL, there are still some debates over its over all effects and it being used as an alternative to ephedrine, a substance made illegal by many countries due to the side effects including heart disease.

Theobromine, which is a mild diuretic and mild stimulant. Theobromine can be found in cocoa and chocolate products. Theobromine is most commonly used for its diuretic effect.

Yohimbine HCL raises body temperatures. it increases the flow of blood to the genital area and increases the sex drive in men but also women have reported similar effects.
