Sympathomimetic drugs are compounds that mimic or imitate the effects of the hormone epinephrine (adrenaline) and the hormone/neurotransmitter norepinephrine (noradrenaline).Clenbuterol is a popular drug prescribed as a decongestant and bronchodilator and commonly used by sufferers of asthma. However, it is now becoming popular as a dietary supplement endorsed as an effective slimming pill.HOW DOES IT WORKS?Clenbuterol is on of the most popular and potent cutting agents available. Clenbuterol is known to burn fat with thermogenic properties and also build lean muscle mass. Clenbuterol is a potent, long-lasting bronchodilator that is used in some European countries to treat asthma and related lung disorders. However, the drug is also a potent thermogenic agent and can selectively decrease fat and increase lean muscle mass. This property of Clenbuterol has made it a widely abused drug among many individuals. Because of this selective partitioning effect, the drug is widely abused by both amateur and professional athletes around the world.Many bodybuilders, as well as other athletes, find Clenbuterol beneficial because of its thermogenic abilities. As a thermogenic it increases blood pressure, stimulating the heart muscles. This stimulation, in turn, leads to an increase in body temperature. In addition, Clenbuterol boosts glycogenolysis, or the breakdown of glycogen. This process results to release of glycogen into the bloodstream (in the form of glucose) and renders the body incapable of storing or using more glycogen. This hikes the rate at which fat and protein are used up in the body for these three essential purposes – energy production, for recycling of their molecular components, or for their excretion. This is how Clenbuterol users lose adipose (fat) tissues.Clenbuterol is also particularly appealing to bodybuilders and other athletes because it heightens aerobic capacity. Aerobic means "with oxygen", and refers to the use of oxygen in the body's metabolic or energy-generating process. In simple terms, Clenbuterol improves oxygen transportation via increased blood pressure. This makes Clenbuterol a staple of many endurance athletes’ drug protocol.This drug is also used as an anabolic agent although its anabolism effect remains a contentious issue. In several animal studies, it has exhibited anabolism resulting to muscle gains. However, this has not been observed on human subjects.The recommended regimen with this drug is to gradually ramp up its dosage. Slowly build up the intake each day until an effective and comfortable range is established. This way, most of the drug’s effects can be avoided, specifically its negative effect on blood pressure. Males typically take 3-8 tablets a day while females take 2 - 5 tablets a day.The length of time this drug is to be cycled is dependent on the goal of the user. If your objective is to lose fat, Clenbuterol highest efficacy is observed when taken in a period of 4 - 6 weeks. During this phase, it is important to monitor temperature increase or decrease.Remember that as a thermogenic this drug works by elevating the temperature, and thus a decrease or a drop in temperature means its losing its potency. This also signals that you need to break for at least several weeks. Increasing the dosage or prolonging the intake will prove to be ineffective and a total waste of money since the decreased efficacy may mean that the body is growing immune or resistant to its effects.To heighten its fat-burning ability, many stack Clenbuterol with other drugs such as the thyroid hormone Cytomel. This stack is great during contest preparation or cutting cycle when bodybuilders need to get rid of undesirable fat without sacrificing caloric intake.Clenbuterol is also typically stacked with non-aromatizing anabolic steroids, those that do not cause water retention. This stack regimen induces the so-called synergistic effect of drugs.Clenbuterol dosage is dependent on body weight and can be optimized by measuring the body temperature. Athletes usually take 5 - 7 tablets, 100 - 140 mcg per day. For women 80 - 100 mcg/day is usually sufficient. It is advisable to begin Clenbuterol by taking only one tablet on the first day and then increasing the dosage by one tablet each of the following days until the desired maximum dosage is reached. The compound is usually taken over a period of 8 - 10 weeks.SIDE EFFECTS:Possible side effects of Clenbuterol include restlessness, palpitations, tremor (involuntary trembling of fingers), headache, increased perspiration, insomnia, muscle spasms, increased blood pressure, and nausea. Individuals who have been diagnosed of cardio-vascular problems should not take Clenbuterol.
