        Clenbuterol
        Chemical Name: Clenbuterol Hydrochloride
        Drug Class: Lipolytic (fat burner)

        Clenbuterol (often called just “Clen”) is used by athletes and bodybuilders for it’s ability as a beta-2 agonist. It therefore stimulates your beta-2 receptors, which in turn help you to lose fat by allowing your body to release and burn more stored fat. Clen has been used for literally decades in the foreign veterinary world, for increasing the lean yield of livestock. It is clearly a very effective agent for this purpose, although its long half life and tendency to stay active in the body for long periods of time mean that vets in the United States aren’t able to use it. This is also the reason why (although it’s an asthma medication) it’s not available to asthmatics in the US of A. Albuterol is Clen’s shorter acting cousin, and that’s the FDA’s drug of choice here. But in the world of athletics, Clenbuterol has a much longer history of use.

        Specifically, it’s used for fat loss, and since we’re talking about fat loss here, and this purpose is what it’s most often used for by athletes. Briefly stated, Clen is used as a repartitioning agent, and what this means is simply that it will increase your ratio of Fat Free Mass (FFM) to Fat Mass (FM) (1). When you use Clenbuterol, besides (of course) noticing some fat loss, you’ll feel your body temperature rise a bit, and your appetite will be slightly repressed. (2)

        Anyway, as you may have guessed, because the FDA doesn’t allow Clenbuterol use in asthmatics, and the USDA doesn’t allow it in livestock, there aren’t a lot of human studies to really examine with regards to Clenbuterol. Unfortunately this makes research a bit difficult, as it’s well known that animals have a some important differences in their beta-receptor type and concentrations, but animal studies are still quite useful here.

        Clenbuterol is quite anti-catabolic and/or anabolic in almost every (animal) study ever done on it, although this hasn’t been studied or confirmed in human studies (3). Also, a trend we see with Clenbuterol administration in animals is that the doses used are very high- more than anyone I’ve ever heard of actually taking. So, what I’m saying is that if Clenbuterol is anabolic or anti-catabolic in humans, only mild anabolic or anti-catabolic effects can realistically be expected. We can take a look at horses given a human-like dose of clen (slightly over 1mcg/lb x2 a day) and exercised for nearly human-like times (20mins, 3x a week) showed very significant decreases in %fat (-17.6%) and fat mass (-19.5%). Interestingly, this significantly increased (+4.4%) at week 6 (1). This has been one of the reasons I have never believed in the 2 weeks on and 2 weeks theory of Clenbuterol administration. Why wouldn’t we want to use it for at least 6 weeks, considering the fact that it seems to have some profound effects during later administration. A “second wind” so to speak (get it? “second wind”? it’s an asthma med! Ha! Ok…moving along…).

        One of the primary drawbacks of Clenbuterol is that after a couple of weeks, it seems to stop working for most people. This is because it can cause a downregulation of pulmonary, cardiac and central nervous system beta-adrenergic receptors(4). This is why it seems to stop burning fat for most people at that point. To counteract this, you can take some Ketotifen, Benadryl, or Periactim every 3rd or 4th week that you remain on Clenbuterol. These are prescription anti-histimines, so they’ll make you drowsy (take before bedtime).

        Also, bear in mind that clen isn’t great for your heart, and can cause some issues there (enlargement of ventricles, etc…) but most studies showing Clen to cause heart problems are with animals, and even though the dosing is almost similar to what humans take (in some studies its within range of what would be double of a large human dose...). Again, it’s important to remember that animals have more beta-2 receptors and they cause certain event chains that humans’ beta-2 receptors may not, due to their relatively high concentrations. Clen causes cardiac hypertrophy to some degree, in some cases and even dose-dependent apoptotic and necrotic myocyte death (5). And since Clen depletes taurine (6) as do most if not all beta-agonists, you may want to supplement your Clen use with some Taurine.

        One of the weirdest things about Clenbuterol is that even though it’s an asthma medication, studies have shown reduced exercise (cardiovascular) performance with Clen (7), but some also show that Clen can alleviate exercise induced asthma (8)!

        Clenbuterol is one of the easiest drugs to find proper dosing for, and I’ve always made the same recommendations as to finding the appropriate dose for you. Basically, start with 20mcgs upon rising. If the side effects (possible anxiety, and shaking or sweating) aren’t too pronounced, then repeat that same dose again later in the day, and then once again in that day (again, if you find you can tolerate the effects). If you start experiencing intolerable sides, then decrease the does to where it’s tolerable. If not, then start increasing the dose more, very gradually.

        Don’t go over 200mcgs, though…and keep your Blood Pressure at (or under) 140/90. If your Blood Pressure goes over that, reduce your dose. If side effects are intolerable, decrease your dose.

        Clenbuterol Side Effects
        THE DIFFERENT CLENBUTEROL SIDE EFFECTS


        clenbuterolClenbuterol is commonly known as a weight loss pill all over the world. In the medical field Clenbuterol is primarily used as a bronchodilator for asthmatics and as a decongestant for those who have difficulty breathing. Since it is a very effective fat burner it has been used and abused in and out of the bodybuilding and athletic circles. As a matter of fact Clenbuterol is mostly abused in the entertainment industry since it is very popular among celebrities in keeping a trim and flab free body. It is considered a classic cutting steroid. However, there are no known researches that can back up the usage of Clenbuterol as a weight loss drug. Therefore, users should be extremely cautions when using this drug. Just like any other steroid, Clenbuterol has its share of side effects. Clenbuterol side effects are attributed to its characteristic as a thermogenic drug.

        While Clenbuterol is a good diet pill, it is not advisable to take the steroid without knowing Clenbuterol side effects. Clenbuterol is a Beta 2 sympathomimetic steroid. Sympathomimetic steroids affect the sympathetic nervous system. They are often used to treat cardiovascular and bronchial conditions such as asthma and hypertension. Since the initial effect of the steroid is to increase body temperature it is recommended that users stick to doses below 140mcgs. Perhaps the most noticeable Clenbuterol side effect would be the tremors and excessive sweating. This is to be expected since Clenbuterol has already began to work in the system. It has begun its fat and calorie burning process. As dosage is increased in increments of 20mcgs the faster fat is reduced.

        As increased dosage of Clenbuterol is administered to the body, it will experience more severe Clenbuterol side effects. Since this steroid affects the sympathetic nervous system the shaking of the hands and muscular tremors are a sign of its more severe Clenbuterol side effect which is nervousness. You may also experience muscular cramps. Clenbuterol also targets smooth muscles such as the cardiovascular muscles which in turn could cause palpitations, possible cardiac hypertrophy, and heart muscle necrosis which was noticed on animals but could affect humans as well. An experiment was done on horses to test the potency of Clenbuterol as a weight loss drug. It was discovered in the experiment that when the horses were given the same exercise regimen of humans there was a considerable drop in their weight.

        Check with your trainer or physician before using any steroid. Even those that claim to be same even in small doses can be harmful. Since Clenbuterol is a weight loss drug it can be very addictive. When there is increased dosage of Clenbuterol,side effects are also increased. Like with any steroid it is also very dangerous. Over dosage can produce Clenbuterol side-effects such as heart problems. It is also considered illegal in most countries so aside from knowing the Clenbuterol side-effects it is also best that you know the laws of your country pertaining to steroids.
