11-Hydroxy Yohimbine- The claim is that it releases Norepinephrine and this in turn maximizes metabolism and so burns body fat.

Ashwagandha, a herbal extract that typically contains withanolids and flavonoids. Ashwagandha is commonly used for energy, stress management and as an antioxidant.

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.

Catechins are a polyphenolic antioxidant metabolite obtained from plants. It is abundant in tea derived from tea plants (about 25% by weight) and in cocoa. Catechin is also found in chocolate, fruits vegetable and wine. The health benefits of catechin have been studied on human model, and it has been found to reduce carcinogenesis. According to some studies Catechin can reduce the risk of four of the major health problems: stroke, heart failure, cancer and diabetes. Green tea catechin has also been shown to possess antibiotic properties. Catechins, when combined with habitual exercise, have been shown to delay some forms of aging; in an experiment Mice fed catechins showed decreased levels of aging.

EGCG or Epigallocatechin gallate is among the major catechins found in green tea. It belongs to the class flavan 3 ol of flavonoids, and is polyphenolic matter. Black tea also contains EGCG but in lower quantities. Epigallocatechin gallate makes up about 30% of dry weight of the green tea leaves. EGCG is the most powerful antioxidant present in green tea. It helps to burn fat, increase metabolism, and lower the storage of fat. Researches show that EGCG can be beneficial in curing many types of cancers, like bladder, cervical, prostate, and brain cancer. It also builds up the immune system and protects the body from many diseases.

Evodia Rutaecarpa has been used in China by the native medicine and herbology practitioners for centuries as a weight loss agent. The Tetradium plant, as it is also known, as well as the bee bee tree, is native to Asia and the chemical associated with the weight loss effect has been isolated as evodiamine. In trials on mice it has been proven that the uptake of fat was significantly reduced by the specimen receiving the Evodia Rutaecarpa extract. While human testing was never truly conducted, the use of Evodia Rutaecarpa extracts in weight loss products seems to prove the interaction with the uncoupling protein 1, or UCP1, also named thermogenin. The stimulation of thermogenin by Evodia Rutaecarpa extract leads to energy being burned as heat, burning excess calories and consequently stored fat.

Green Tea Extract- By increasing the body's metabolism, it is widely believed that green tea extract largely aids in weight loss.

Guggulsterone- Commiphora wightii, or the so called Guggul tree is a flowering shrub or rather a small tree which can grow up to a size of 4 meters. Once very common in India, it is now there listed as endangered, but not in northern Africa or elsewhere in central Asia. It was very popular in the Indian Ayurvedic medicine, but also currently in the western medicine for treating of heart problems. The hydrocarbon secretion of Guggul contains a plant sterol, guggulsterone, which in the human body seems to act as an antagonist to the farnesoid X receptor. Furthermore, guggulsterone is active in increasing the natural thyroid production. This in turn stimulates the metabolism and may raise the body temperature, burning stored excess fat.

L-Tyrosine is a non essential amino acid occurring in the body. L-Tyrosine may be created from the synthesis of phenylalanine which is also an amino acid. It is one of the building blocks of proteins in the body. It is also a precursor for several neurotransmitters such as L-dopa, dopamine, epinephrine and norepinephrine. It helps treat and prevent illness such as Parkinson’s disease, Alzheimer’s disease, depression and other such mood disorders. It also helps protect the body from free radical damages. It also helps protect the skin from UV rays damages on the skin by aiding in the production of melanin. It also helps in increasing the metabolic rate that speeds up muscle building and fat loss. It also increases the endurance.

Octopamine is a biogenic substance which is containing an amine group, apparently related to noradrenaline, which is a catecholamine functioning as both, neurotransmitter and a hormone. Similar to norepinephrine, which is another name for noradrenaline, octopamine may act as a stress hormone, triggering increased heart rate, energy consumption and blood flow, even the blood pressure. One side effect of octopamine is apparently the release of fat from the adipocytes, which are the fat cells where excess energy is being stored. This side effect prompted the use of octopamine as a dietary supplement aimed at weight loss, but used in combination with other stimulants. Octopamine has been discovered in the middle of the twentieth century, but the use as a fat removal agent is very recent.

Polyphenols.

Tyrosine Alpha-Ketoglutarate

Tyrosine Decanoate

Tyrosine Ethyl Ester is a derivative of the amino acid tyrosine. It contains an ethyl group bonded to the tyrosine through an ester linkage. This product is used whenever a supplementation with tyrosine is required. It has an advantage over using simple L-tyrosine because it is more bio-available. This means that if equal amounts of L-tyrosine and tyrosine ethyl ester are administered, greater amount of the latter will reach the systemic circulation. Tyrosine ethyl ester has a number of benefits including modulating the effects of stress by controlling nor-epinephrine levels, and the symptoms of stress and stimulating fat loss by stimulating the release of catecholamines.

Yohimbine HCL, also known as 17-hydroxy-yohimban. Yohimbine is an odorless; white crystalline powder; scarcely soluble in water; soluble in chloroform and alcohol. The chemical title is 17-hydroxy-yohimban-16- carboxylic acid, methyl ester. Yohimbine works as a weak blocker of alpha-adrenergic receptor. It is used in angina pectoris and arteriosclerosis, and has been used as a mydriatic and local anesthetic and for its supposed aphrodisiac properties. Yohimbine is a therapeutic derivative of the bark of a tree named Corynanthe yohimbine.
