Research Chemicals are fundamental in the development of novel pharmacotherapies. Common medical laboratory uses include in vivo and animal testing to determine therapeutic value, toxicology testing by contract research organizations to determine drug safety, and analysis by drug test and forensic toxicology labs for the purposes of evaluating human exposure. Many pharmacologically active chemicals are sold online under the guise of “research chemicals,” when in reality they are untested designer drugs that are being consumed by buyers taking advantage of many of the compounds’ transitional or nonexistent legal status.Buy Research Chemicals stimulants online
Benzodiazepines (BZD, BZs), sometimes called “benzos”, are a class of psychoactive drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. The first such drug, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955, and made available in 1960 by Hoffmann–La Roche, which, since 1963, has also marketed the benzodiazepine diazepam (Valium).In 1977 benzodiazepines were globally the most prescribed medications.They are in the family of drugs commonly known as minor tranquilizers
Benzodiazepines enhance the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABAA receptor, resulting in sedative, hypnotic (sleep-inducing), anxiolytic (anti-anxiety), anticonvulsant, and muscle relaxant properties. High doses of many shorter-acting benzodiazepines may also cause anterograde amnesia and dissociation.These properties make benzodiazepines useful in treating anxiety, insomnia, agitation, seizures, muscle spasms, alcohol withdrawal and as a premedication for medical or dental procedures. Benzodiazepines are categorized as either short-, intermediate-, or long-acting. Short- and intermediate-acting benzodiazepines are preferred for the treatment of insomnia; longer-acting benzodiazepines are recommended for the treatment of anxiety.
The major stimulant drugs are amphetamines and related compounds, methylxanthines (methylated purines), cocaine, and nicotine. Amphetamines achieve their effect by increasing the amount and activity of the neurotransmitter norepinephrine (noradrenaline) within the brain. They facilitate the release of norepinephrine by nerve cells and interfere with the cells’ reuptake and breakdown of the chemical, thereby increasing its availability within the brain. The most commonly used amphetamines are methamphetamine (Methedrine), amphetamine sulfate (Benzedrine), and dextroamphetamine sulfate (Dexedrine). Amphetamines were first used in the 1930s to treat narcolepsy and subsequently became prescribed for obesity and fatigue. Their heavy or prolonged use causes irritability, restlessness, hyperactivity, anxiety, excessive speech, and rapid mood swings. Still higher doses or chronic use can cause agitation, tremor, confusion, and, in the most serious cases, a state resembling paranoid schizophrenia.
