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 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. Synephrine HCL is mainly used to aid fat loss, appetite suppression and energy. Each capsule of Synephrine HCL contains 20 mg and each container has 100 capsules. Synephrine HCL is taken as a dietary supplement prior to meals. Synephrine HCL can be taken three times everyday. However, individuals below 18 are not recommended to use. Even nursing or pregnant women are not recommended for use. It is best to take this after consulting a healthcare professional so that if one is diagnosed with heart or kidney disease, renal or recurrent headaches, asthma, depression or any such and is continuing with those medicines may or may not be advised to take Synephrine HCL.

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.

Yohimbine HCL, sometimes called yohimbine hydrochloride, yohimbe, or yohimbe bark, is an herbal supplement which serves as a stimulant and possible aphrodisiac for users. Yohimbine has also been shown to be successful in treating erectile dysfunction and impotence in men. It may serve to boost the sex drive of those who take it for aphrodisiac purposes. Some people are recommended to take yohimbine to combat their lower sex drives caused by antidepressants. Yohimbine has also been shown to help blood pressure levels and assist in weight loss. For these reasons, yohimbine is a popular supplement amongst athletes as well as many others wishing to improve their health.
