Description: Is available in 10 - 20 mcg tablets or in the .016 mg/gram Ventapulmin Vet variety. Clenbuterol is known as a sympathomimetic. These hormones are taken to mimic adrenaline and noradrenaline in the human body. Clenbuterol is a selective beta-2 agonist that is used to stimulate the beta-receptors in fat and muscle tissue in the body. Clenbuterol exhibits most of its effects on the stimulation of both type 2 and 3 beta-receptors. Clenbuterol is really one of bodybuilding's most misunderstood performance enhancement drugs. It is true that it is effective in helping to burn bodyfat but it is often been stated that clenbuterol is effective in causing anabolic gains and has in times even been compared to some of the weaker anabolic steroids. Books such as the World Anabolic Review, 1996, by P. Grunding and M. Bachmann state incorrectly that, "its effects, however, can by all means be compared to those of steroids. Similar to a combination of Winstrol Depot and Oxandrolone...." These statements are inaccurate and misleading to say the least. A lot of these claims as to the anabolic effects of clenbuterol are derived from studying the effects of clenbuterol on livestock. Clenbuterol is effective in increasing muscle mass and decreasing fat loss in animals.
The problem with the variation in anabolic effects between humans and livestock is that livestock have an abundance of the type 3 beta receptors whereas humans have little if any of the type 3 beta receptors. These beta-3 receptors increases insulin secretion and sensitivity, causing more glucose and amino acids to be transported into skeletal muscle thus causing the anabolic effects that we, humans, just aren't seeing. As Dan Duchaine stated in his Muscle Media article on clenbuterol, "In those animal research studies showing an anabolic effect from clenbuterol, it's my guess the anabolism happens specifically when the beta2 receptor stops working. At that point, the beta3 increases and causes the anabolic effect through insulin mechanisms." Since humans, again, have either very little or no beta-3 receptors, there is no chance of this anabolic effect. Just another of the studies where everyone assumed that what works in animals must work in humans. This is just simply not the case with clenbuterol.
Clenbuterol does work very effectively as a fat burner. It does this by slightly increasing the body temperature. With each degree that the temperature in your body is raised from the use of clenbuterol, you will burn up approximately an extra 5% of maintenance calories. This makes it effective as a fat burner. Your body will fight this by cutting down on the amount of active thyroid in the body as well as through beta-receptor down regulation, which explains why you only have a limited effective period to take clenbuterol. While I am on the subject of beta-receptor down regulation, I would like to dispose of another myth. This involves the two on/two off cycling theory that I believe was originated by Bill Phillips in the Anabolic Reference Guide and has somehow made it's was into every other steroid book since then including the WAR and Physical Enhancement with an Edge. The two on-two off theory simply will not work because of one main reason: the half life of clenbuterol. This 2-on/2-off idea was a THEORY ONLY, not by a doctor or scientist, and not based on specific knowledge of clenbuterol, but derived by imitation from other drug's with shorter half lives.
Clenbuterol has been reported as having a half life of about 2 days, but that is not actually correct, since it has biphasic elimination, with the half-life of the rapid phase being about 10 hours, and the slower phase being several days. Supposedly, this is one of the reasons the FDA never approved clenbuterol as an anti-asthmatic drug...the FDA frowns on drugs with long half-lives if drugs with more normal half-lives are available. So with a 2-on/2-off cycle you never have time to get enough of the clenbuterol out of your system for this theory to be reasonable. In actuality, it probably hasn't even dropped to 50% of your peak concentration before you are taking the drug again. With this all taken into account, there is no reason to think that this cycling would significantly reduce the problem of receptor desensitization. A more reasonable approach would be either one week on, one week off, or alternately, two weeks on two weeks off. The two week cycle has the disadvantage of a "crash" period afterwards. This crash period can be helped with the use of ephedrine to lessen the lethargy that you will experience.
If you are interested in taking clenbuterol for anything other than fat loss then you might as well stay away from this compound. There is a lot of talk as to how clenbuterol compares to ephedrine as well. Most "experts" feel that clen gives a better bang for the buck than the ECA stack. It should be noted that clenbuterol’s results and effects are much shorter lived. They work through very similar mechanisms. Both products stimulate the beta-receptors but clenbuterol seems to be a more refined version, called a second generation beta-agonist drug, than ephedrine. Clenbuterol targets the proper receptors, being the beta-2 and 3 receptors than ephedrine more specifically which should in theory make clenbuterol more effective of a fat burner. Again, most of the so called "experts" say that clenbuterol is more effective than ephedrine. I, personally, get worse results with clen vs. the good old ECA stack. Clenbuterol also didn't blunt my hunger either and I ate more while taking it as well. I also seem to get much better effects out of cytomel as a fat burner as well. Even better than the ECA stack or clenbuterol. But, again, that is my personal opinion.
Effective Dose: 80-140 mcgs. / day in split doses throughout the day. Anything over 140 mcg a day is overkill since the beta receptors can only take so much of a product and then more is just wasteful.
Street Price: $.50 - 1.00 / tab. Fairly inexpensive in Mexico though. Spiropent is currently going for about $3.50.50/box, Novegam for $2.50.25/box, and Oxyflux for about $1.50.30/box.
Stacking Info: One week on, one week off might make sense, or alternately, two weeks on two weeks off makes sense but has the disadvantage of a "crash" period afterwards. You can take ephedrine after the clen to help reduce this "crash" period or at least make it more bearable for you. The two on/two off theory is absolute bullshit and can't work; read above.
Clenbuterol, medically used throughout many parts of the world as a broncodilator for the treatment of asthma, is a recent and popular addition to the realm of athletics. Clenbuterol is a beta-2 agonist, with properties somewhat similar to adrenaline. It acts as a CNS stimulant and users quite commonly report side effects such as shaky hands, insomnia, sweating, increased blood pressure and nausea. These side effects generally subside quickly once the user becomes accustomed to the drug. Athletes find clenbuterol attractive for it's pronounced thermogenic effects as well as mild anabolic properties. Dosage regimes will vary depending on the desired effect. Clenbuterol generally come is 20mcg tablets, although it is also available in syrup and injectable form. Users will usually tailor their dosage individually, depending on results and side effects, but somewhere in the range of 2-8 tablets per day is most common. For fat loss, clenbuterol seems to stay effective for 3-6 weeks, then it's thermogenic properties seem to subside. This is noticed when the body temperature drops back to normal. It's anabolic properties subside much quicker, somewhere around 18 days. Currently, counterfeits of clenbuterol do exist, but they are scarce and most are bottles with loose tablets. Clenbuterol should only be trusted when purchased in foil and plastic strips, preferably with accompanying box and paperwork.
This is a very interesting drug, which has recently become popular amongst bodybuilders.
Clenbuterol itself, is a third generation beta agonist. Clenbuterol's use as a bodybuilding drug item from a number of medical reviews which have cited its outstanding potential to promote muscle gains as well as fat loss. It has been used in parts of England for several years by a limited number of elite athletes. More recently, due to the steroid crackdown, there have been an increasing number of American bodybuilders that are experimenting with this drug. Clenbuterol is indeed the most intriguing ergogenic aid I have studied with the sole exception of anabolic steroids.
Many athletes who use Clenbuterol claim that it promotes dramatic strength increases and a very noticeable reduction in body fat some athletes claim that they enjoyed significant gains in muscle mass while using Clenbuterol. Clenbuterol's most valid application seems to be as a pre-contest, cutting drug. It is not banned by any athletic committee; thus, numerous professional bodybuilders have used it for the last month of contest preparation. Athletes have used between 60-120 mcgs taken in divided doses daily. Because it causes a great deal of receptor downgrade it should not be used continually. Research shows that using it for two days, then taking two days off prevents attenuation. Cycles range from 6-12 weeks in length. Side effects include nervousness, tremors of the hands, headaches, and insomnia. Usually these side effects are dose related. It comes in 20 mcg tablets. Clenbuterol is being counterfeited under numerous manufacturer names in the United States.
This drug is classified as a beta-2 adrenergic agonist. Clenbuterol is a bronchiodilator. This drug is banned by the FDA although it is used outside the US by asthma patients. The reason although it is fairly anabolic, and it promotes the burning of fatty acids through brown fat burning. Clenbuterol is a little scary because of some other side effects including the following: tremors, sweating, sleeplessness, rapid heartbeat, etc. These side effects vary in people. Some people aren’t affected at all. This drug comes in tablets of 20 mcg (micrograms not milligrams ). Dosages are normally between 20-120 mcg for bodybuilders that use this. It should be taken in a 2 days on /2days off fashion because this drug becomes ineffective for its anabolic properties after 18 successive days of use. The receptor sites seem to be non-responsive for anabolic purposes if taken continuously, but brown fat-burning will continue past the 18 day period. It shouldn’t be used this way for more than 12 weeks. After 12 weeks, the drug should be discontinued for a couple of months.
Clenbuterol (clenbuterol hydrochloride) is a prescribed asthma medication which is catabolic to fat and anabolic to muscle. Clenbuterol is not a steroid hormone but a beta-2-symphatomimetic.
Clenbuterol can cause a solid, highly qualitative muscle growth which goes hand in hand with a significant strength gain. Clenbuterol also has a strong anti-catabolic effect, which means it decreases the rate at which protein is reduced in the muscle cell, consequently causing an enlargement of muscle cells. For this reason, numerous athletes use clenbuterol after steroid treatment to balance the resulting catabolic phase and thus obtain maximum strength and muscle mass. Please note, though, there are no scientific evidence these effects, that are proven in animals, also occurs in humans during the use of clenbuterol.
Clenbuterol works very effectively as a fat burner. It does this by slightly increasing the body temperature. The rise is not usually dramatic, a half of a degree, sometimes a little more but rarely more than one degree. This elevation is due to the body will burn excess energy (largely from fat) and is usually not uncomfortable.
The body will fight this, though, by cutting down on the amount of active thyroid in the body as well as through beta-receptor down regulation, which explains why clenbuterol is effective only over a limited time period.
Clenbuterol hydrochloride comes as a tablet, 0.02 mg., to take by mouth.
Common dosage of clenbuterol is 5-7 tablets, 100-140 mcg per day. For women 80-100 mcg/day are usually sufficient. It is important to begin 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.
Athletes have made a habit of cycling clenbuterol in an effort to minimize side effects as well as prevent receptor downgrade. Average cycle length on clenbuterol is 6-10 weeks with a 4-6 week off period. There are also those who suggest a two days on, two days off cyclus and there are strong evidence this method will minimize the side effects of taking clenbuterol. There are, though, no evidence the method is the most efficient in terms of fat loss.
There are also suggestions of using clenbuterol in a two week on, two week off pattern, which makes sense when taking the characteristics, especially the long 35 hour half-time, of the compound in consideration. Tapering is not needed but can be suitable for some in order to avoid a possible "crash" period.
CNS stimulants, for instance ephedrine, are not advised to use with clenbuterol as the negative side effects would be exaggerated.
Before the use of clenbuterol, consult a physician if you have heart or thyroid diseases, high blood pressure, diabetes, glaucoma, difficulty in urination due to an enlargement of the prostate gland or if you are taking any prescription drugs. Do not use clenbuterol if you are currently taking or have recently taken MAO inhibitor drugs.
Use clenbuterol with caution in hypersensitive and diabetic individuals and in individuals with latent or clinically recognized angle closure glaucoma, coronary artery disease, congestive heart failure, prostatic hypertrophy, hyperthyroidism, urinary retention.
Safety for use in pregnancy and lactation has not been established.
Clenbuterol may impair the mental and/or physical abilities needed for certain potentially hazardous activities such as driving a car or operating machinery.
Possible side effects
The most common is muscle cramps which a potassium supplement, helping to maintain the electrolyte status, would drastically reduce.
Possible side effects of clenbuterol also include restlessness, palpitations, tremor, headache, increased perspiration, insomnia, possible muscle spasms, increased blood pressure and nausea. Note that these side effects are of a temporary nature and usually subside after 8-10 days, despite continuation of the intake of clenbuterol.
Clenbuterol can cause sudden death at very high dosages.
If overdose of clenbuterol is suspected, contact your local poison control center or emergency room immediately.
Keep clenbuterol in a tightly closed container and out of reach of children. Store clenbuterol at room temperature and away from excess heat and moisture (not in the bathroom).
The above information is intended to supplement, not substitute for, the expertise and judgment of your physician, or other healthcare professional. It should not be construed to indicate that use of clenbuterol is safe, appropriate, or effective for you. Consult your healthcare professional before using clenbuterol.
The substance Clenbuterol hydrochloride is also available in various other forms of administration, including syrups, drops, liquids, dosing aerosols, injectable solutions, and granules. Since athletes usually prefer tablets, manufacturers and trade names- offering this oral version are listed.
Clenbuterol is a very interesting and remarkable compound. It is not a steroid hormone but a beta-2-symphatomimetic. Clenbuterol, above all, has a strong anti-catabolic effect, which means it decreases the rate at which protein is reduced in the muscle cell, consequently causing an enlargement of muscle cells. For this reason, numerous athletes use Clenbuterol after steroid treatment to balance the resulting catabolic phase and thus obtain maximum strength and muscle mass. A further aspect of Clenbuterol is its distinct fat-burning effect. Clenbuterol burns fat without dieting because it increases the body temperature slightly, forcing the body to burn fat for this process. Due to the higher body temperature Clenbuterol magnifies the effect of anabolic/androgenic steroids taken simultaneously, since the protein processing is increased.
Athletes usually take 5-7 tablets, 100-140 mcg per day For women 80-100 mcg/day are usually sufficient, It is important that the athlete begin 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. Since Clenbuterol is not a hormone compound it has no side effects typical of anabolic steroids. For this reason it is also liked by women. Possible side effects of Clenbuterol include restlessness, palpitations, tremor (involuntary trembling of fingers), headache, increased perspiration, insomnia, possible muscle spasms, increased blood pressure, and nausea. Note that these side effects are of a temporary nature and usually subside after 8-10 days, despite continuation of the product. In the meantime, Clenbuterol is well distributed on the black market and costs between $0.00.70 and $0.50.20 per 0.02 mg tablet. Clenbuterol by Novegam is one of the most popular versions on the market today.
Clenbuterol is a widely used bronchodilator in many parts of the world. It is most often prepared in 2Omcg tablets (see: Spiropent), but Clenbuterol is also available in syrup and injectable form (see: Spasmobronchal). This drug belongs to a broad group of drugs knows as sympathomimetics. Clenbuterol affect that sympathetic nervous system in a wide number of ways, largely mediated by the distribution of adrenoceptors.
Use of Clenbuterol
The drug is specifically a selective beta-2 sympathomimetic, primarily affecting only one of the three subsets of beta-receptors. Of particular interest is the fact that Clenbuterol has little beta-i stimulating activity. Since beta-i receptors are closely tied to the cardiac effects of adrenoceptors, this allows to reduce reversible airway obstruction (and effect of beta-2 stimulation) with much less cardiovascular side effects compared to non-selective beta agonists. Clinical studies with Clenbuterol show it is extremely effective as a bronchodilator, with a low level of user complaints and high patient compliance Clenbuterol also exhibits an extremely long half-life in the body, which is measured to be approximately 34 hours long. This makes steady blood levels easy to achieve, requiring only a single or twice daily dosing schedule at most. This of course makes it much easier for the patient to use, and may tie into its high compliance rate. To spite that Clenbuterol is available in a wide number of other countries however; Clenbuterol has never been approved for use in the United States. The fact that there are a number of similar to Clenbuterol, effective asthma medications already available in this country may have something to do with this, as a prospective drug firm would likely not find it a profitable enough product to warrant undergoing the expense of the FDA approval process. Regardless, foreign Clenbuterol preparations are widely available on the U.S. black market.
