since alot of people are looking for fat loss, i thought i would post a few articles on this drug, its known as a more refined version of ephedrine. I know alot of people dont agree with taking this sort of stuff but it never hurts to gain a bit of knowlege.


What is Clenbuterol and what does it do?
Clenbuterol (often referred to simply as 'Clen') is not a steroid, but a Beta 2 Sympathomitetic and central nervous system (CNS) stimulant. It is a specific agonist, stimulating the adrenergic beta 2 receptors. It is used in certain countries in a medical sense as a bronchodilator in the treatment of asthma, though not in the UK and USA, mainly due to its long half life.

Athletes and bodybuilders use the drug due to its thermogenic and anti-catabolic effects. This is down to its ability to slightly increase 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 also 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 receptors which increase insulin production and sensitivity.
Clenbuterol is dosed in micrograms (mcg/µg), most commonly in tablet form, though there are other forms of administration such as liquids, nasal sprays and injectables. Note: Although dosages are in microgram amounts, many manufacturers will list the active ingredient as milligrams (mg), so a tablet of 20mcg will be labelled as 0.02mg.

What are the side effects/possible implications?

Side effects are dose 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 as side effects are likely to be cumulative. It is for this reason that it is generally not recommended to use ephedrine/ephedra (or ma huang) or the ECA stack (ephedrine-caffeine-aspirin) whilst using clen.


Characteristics:
Clenbuterol is a very widely used drug and has quite a reputation. A good one among athletes and recreational users, and a very bad one among those people who know very little about illegal performance enhancing aids. Its not a steroid. In fact, the only medical use for which clenbuterol is generally prescribed (and now being less and less prescribed thanks to its illegitimate use) is for obstructions of the air-way. People with chronic breathing disorders like asthma use this as a bronchodilator to make breathing easier. But its only one of the many things that can be achieved with the use of clenbuterol.

In terms of action this drug is best likened to the now also illegal ephedrine and its legal replacement, ma huang. All of them operate mainly by increasing the manufacture and secretion of catabolic hormones known as cathecholamines (like dopamine, epinephrine (adrenaline) and norepinephrine (noradrenaline)) which are secreted from the adrenal region. Now these hormones have a wide variety of functions. First of all they seem to alter the contractile characteristics of smooth muscle, but very specifically. Some will apparently be stimulated, and others inhibited. Amongst those inhibited, the smooth muscles in the bronchial tree, which explains its soothing effect in patients with breathing problems. What it also does is increase thermogenisis. This usually encompasses a rise in blood pressure, a stimulatory effect of the heart muscle and a resulting rise in body temperature.
Along with the reversing of the effects of insulin (and inhibiting the action of insulin) which results in a release of glycogen back into the blood stream as glucose and an inability to store or use more glycogen, it will increase the rate of protein and fat being burned in the body. For bodybuilders that appears to be the primary use of the drug. This thermogenisis and an increase in the rate of fat being burned usually has as a result that the metabolic rate of the subject its much higher and he burns more calories. This in turn results in loss of adipose tissue (the shedding of fat in other words) revealing a leaner physique with cuts and striations. The downside to this effect is that there is a concomitant rise in the rate of protein being burned. Where fat is robbed from the fatty tissue in the body, protein is generally robbed from the muscle. As with all catabolic hormones, in time muscle loss can and will occur. Which is why many opt to use this compound during a cycle of anabolic steroids that will help preserve the lean body mass while reducing the fat.
