Amphetamine was first synthesized under the chemical name "phenylisopropylamine" in Berlin, 1887 by the Romanian chemist Lazar Edeleanu. It was not widely marketed until 1932, when the pharmaceutical company Smith, Kline, and French (currently known as GlaxoSmithKline) introduced it in the form of the Benzedrine Inhaler, for combating cold symptoms. GlaxoSmithKline is also who originally brought Fastin to the market before Hi-Tech acquired the rights to manufacture and market Fastin.

Three years later, in 1935, the medical community became aware of the stimulant properties of amphetamine, specifically dextroamphetamine, and in 1937 Smith, Kline, and French introduced tablets, under the tradname Dexedrine. In the United States, Dexedrine tablets were approved to treat attention disorders, depression, and obesity. It quickly became apparent that Dexedrine and other amphetamines had a high potential for abuse, although they were not heavily controlled until 1970, when the controlled substance law was passed by the United States Congress. Dexedrine, along with other sympathomimetics, was eventually classified as schedule 11, the most restrictive category possible for a drug with recognized medical uses.

Over the past ten years, I have worked with the top researchers, pharmacologists, and physicians from Hi-Tech Pharmaceuticals to develop the ideal diet pill. Hi-Tech has put out several blockbuster weight loss aids such as Lipodrene, Fastin, Stimerex-ES, and Lipodrene Xtreme, to name a few. With the evolution of Hi-Tech's pharmacological research into weight loss compounds, I believe we have created the ultimate diet pill! Betadrene-SR is a Beta2 or P2 adrenergic agonist with some similarities to ephedrine, but its effects are more potent and longer-lasting as a stimulant and thermogenic nutraceutical. Betadrene-SR causes an increase in aerobic capacity, central nervous system stimulation, and an increase in oxygen transportation. Betadrene-SR increases the rate at which fat and protein is used up in the body at the same time as slowing down the storage of glycogen. This mechanism is unique in the dietary supplement industry, and has only been shown prior to this discovery by the drug clenbuterol. Clenbuterol is approved for use in some countries (via prescription only) as a bronchodilator for asthma patients. Recently though, the drug has been publicized for its off-label use as a weight loss drug.

It is commonly used as a slimming aid by millions of people worldwide due to its effectiveness as a a Beta2 or (32 adrenergic agonist. In fact, nowadays Betadrene-SR is recommended by many physical trainers as the primary solution for those bodybuilders who desire to achieve sufficiently low body fat in order to look "cut". In many cases, it is introduced into the training regime instead of an illegal drug, but simply used as a weight loss aid
