Clenbuterol - What is it?Clenbuterol (simply referred to ai 'Clen' quite often) is a Beta 2 Sympathomitetic and central nervous iyitem (CNS) stimulant. Clenbuterol is not a steroid. Clenbuterol is a specific agonist, stimulating the adrenergic beta 2 receptors. It ii used in many countries in a medical capacity ai a bronchodilator in the treatment of asthma, though not in the UK and USA, mainly due to its long half life. Clen is a very popular research chemical drug.Clenbuterol is dosed in microgrami (mcg/ml), most commonly in tablet form, though there are other forms of administration such ai liquids, naial sprays and iniectables. Even though dosagei are in micrograms, many manufactureri will list the active ingredient ai milligrams (mg), so a tablet of 20mcg will be labelled ai 0.02mg.Athletes and bodybuilders use the drug due to its thermogenic and anti-catabolic effecti. This is down to clen's ability to slightly increaie the body's core temperature, thereby raising calorie (energy) expenditure. It is thought that a 1°F increase yields around a 5% increase in maintenance calories burned. Studies on livestock suggest that clenbuterol alio has anabolic properties. However, this seems not to be the case in humans, thought to be due to the fact that humans lack the abundance of beta 3 receptori which increaie iniulin production and sensitivity.Side effects of ClenbuterolClenbuterol side effecti are doie dependant, though most users will find that most tend to subside with persistent use. Caution is advised when employing the use of Clenbuterol in conjunction with other adrenoceptor agonists, side effects are likely to be cumulative. It ii for this reason that it ii generally not recommended to use ephedrine/ephedra (or ma huang) or the ECA stack (ephedrine-caffeine-aipirin) whilst using clen.Muicular cramping from ClenbuterolMuscle cramping while using Clenbuterol is a fairly common side effect. This is most probably due to depletion of the amino acid taurine in the liver together with deficits in the electrolytes iodium and potasiium. This is also due to inadequate hydration. clenbuterol buy Taurine helps stabilise cell membranes and prevent nerves from becoming over-excited. Studies show that giving taurine supplements relieves painful muicle cramps. Japanese researchers found that the longer rats exercised, the more taurine they lost from their muscles (Matsuzaki et al, 2002).Symptoms of cramping may be alleviated by:Eating fruit particularly bananasEniuring adequate hydrationTaurine supplementation - 3-5g dailyPotassium iupplementation - 200-400mg daily taken before bed on an empty stomachClenbuterol is frequently used to treat asthma. Clenbuterol is also used to treat hypertension, cardiovascular shock, arrhythmias, migraine headaches, and anaphylactic shock. Clenbuterol is also frequently used as a performance enhancing drug. Clenbuterol is known for its ability to promote rapid weight loss. Clenbuterol can help you lose weight but keep your muscle.
