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.

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

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.

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- 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 is a tryptamine alkaloid obtained from a medicinal herb Pausinystalia yohimbe, also known as yohimbe or yohimbe bark. This supplement belongs to the group of stimulant drugs, which has aphrodisiac qualities. Yohimbine chloride—a standardized form of yohimbine—is also used to treat erectile dysfunction. It can also be used to treat sexual side effects caused by some antidepressants (SRRIs), female hyposexual disorder and is also a blood pressure boosting agent and treats orgasmic dysfunction in men. Used orally as a supplement causes significant fat loss in athletes. Yohimbine is an alkaloid obtained from the bark of Pausinystalia yohimbe Pierre where the active ingredient yohimbine HCL (indole alkaloid) is obtained from.
