Clenbuterol – Everything You Ever Wanted To Know

Clenbuterol hydrochloride is common drug used for treating respiratory problems, such as asthma. The effectiveness of the compound has already been proven in some cases, though it still lacks the approval for use by the FDA. However, using Clenbuterol is legal in other nations around the world. Some surmise that the FDA does not approve the drug because of the lack of need for its use. Moreover, there are already other available medications that bear similar effects with the drug.

Aside from treating respiratory problems, Clenbuterol may also be used as thermogenic. Thus, it is not uncommon that the drug is included in various weight loss programs. The drug is also very popular among anabolic steroid users because of its potential in burning fats. On the other hand, a number of competitive builders and athletes rely on Clenbuterol before they engage in different competitions. Meanwhile, nonsteroid users who want to weight loss commonly find themselves using Clenbuterol.


Clenbuterol mainly affects the sympathomimetic nervous system, especially some notable receptors, including the beta-2 receptor. The compound stimulates this receptor, causing reversal in airway obstruction and thus improving breathing functions. The stimulating actions of Clenbuterol also positively affects metabolic rate. Though the drug is not directly involved in fat burning, its stimulation functions leads to increased body temperature. This particular effect occurs through the stimulation of mitochondria by Clenbuterol-activated beta-2 receptors. As a result, more heat is produced by the body, and temperature increases, which will eventually lead to fat burning actions of the body.

Clenbuterol is an anabolic compound, which made it popular among people who are aiming to gain more muscle mass. For steroid users, Clenbuterol is utilized as protective agent during steroid post cycle therapies. However, what people do not know is that the drug is ineffective for such purpose. Scientific evidence have shown that Clenbuterol in fact, promotes anabolic activities in animals. However, the same results are not yet observed in human objects. Thus, Clenbuterol should only be used as bronchodilator and thermogenic.


Clenbuterol is effective in asthma patients because it opens up air passages and thus eases the breathing of affected individuals. Aside from asthma, people also use the drug to address other respiratory problems. Athletes also sometimes use Clenbuterol to improve their breathing and cardiovascular endurance. However, there are other medical drugs that are more effective than Clenbuterol in terms of improving cardiovascular stamina.

In terms of its thermogenic functions, beta-2 stimulation by Clenbuterols leads to increased body temperature. As a result, more calories are burned at a faster rate, leading to improved metabolism. In turn, enhancement in metabolism hastens the breakdown of triglycerides, leading to weight loss.

For those who use the drug for weight loss purposes, they will still have to physically exercise to make their body lean after the weight loss process. Moreover, following a proper diet program should coincide with the use of Clenbuterol and physical exercises. People should realize that the drug only works in hastening metabolic processes, especially fat burning, but it does not eliminate fats per se. The drug is also not recommended for fat or obese individuals. The perfect time for using Clenbuterol is when a person is almost lean so that eliminating that last portion of body fats become easier.

Given its role in weight loss, Clenbuterol is commonly included in programs meant for bodybuilding, figure modification, fitness, and others. For those who enter competitions, the drug is usually taken 8 to 10 weeks prior the main event. Clenbuterol may also benefit individuals who are already lean.


Using Clenbuterol is not without side effects. These side effects may be greatly manifested and sometimes tend to be quite bothersome. Feeling jittery or having a weird sensation is one of the common side effects of Clenbuterol. Clenbuterol users may also suffer from shaky hands and increased sweating. Most users of this drug are expected to experience the said side effects, though they are pronounced in new users. However, as the body gets used to the product, the degree of manifestation of the side effects will gradually diminish over time.

Some Clenbuterol users think that the effects of the drug cease as soon as they stop using it. Though the stimulating effects may decline sometime after use, the fat burning effects may linger for extended periods of time. However, adaptation of the body to the drug, proper plans and adjustment must be made regarding the dosage of Clenbuterol that must be administered afterwar.

Some people also observed other side effects of Clenbuterol aside from the most common ones. Two of these include headaches and nausea. The drug may also cause muscle cramps, which also tend to affect a number of people. Athletes are the most prone to these side effects, that is why they must ensure that they remain hydrated during their training to avoid being negatively affected by Clenbuterol. Meanwhile, some people claimed suffering from insomnia after using Clenbuterol. However, such effect can only be expected from stimulants. The half-life of Clenbuterol lasts for about 34 hours, and user should thus expect some difficulty in sleeping during that period.

The side effects of Clenbuterol may worsen when drug is abused or used in high doses. Severe side effects may come in the form of hypertension, trembling, irregular heartbeat, and panic. There are studies showing that the drug may lead to cardiac hypertrophy, which can become life-threatening.


The recommended daily dose of Clenbuterol is 20 mcg/day, whereas others use an amount of 40 mcg/day. Others may take even higher doses of the drug but only for a limited time. In most cases, the recommended amounts are enough to alleviate respiratory problems.

Meanwhile, when used as thermogenic, people should start with low dosage of the drug then just increase the amount after a certain period. Men commonly start at 40 mcg/day, whereas women are more comfortable with taking 20 mcg/day. After the body has adapted to the drug, the dosage must be increased in order to continue benefitting from the effects of Clenbuterol. There are variety of ways by which Clenbuterol can be used to burn fats. However, only a few of them can be considered effective.


In two-week rotation, Clenbuterol is used for two weeks, then it is followed by two weeks off the drug. This method is common for those who aim to lose weight. They continue this practice until they reach their target weight. At the beginning of the two-week rotation, a person may start by taking 20 mcg/day. This dosage is increased until the maximum amount is reached. After the two-week rotation, an individual may start another rotation of Clenbuterol use at a higher dosage.

Normally, the two-week rotation should be effective. However, during the two weeks when the body is without Clenbuterol, the metabolic rate of the body may decrease. Still, people should not worry about this too much, because it does not guarantee that they won’t be burning fats when they are off from using Clenbuterol. On the other hand, they should ensure that they are following a certain weight loss diet program while using the drug.


After prolonged use, the body starts to adapt to Clenbuterol. As a result, using this drug continuously can be very hard to achieve. At first glance, continuous use of Clenbuterol does not sound logical, especially when its stimulating effects are taken into account. However, this will make sense when people factor in the fact that Clenbuterol may last in the body for several weeks.

Thus, as recommended, Clenbuterol users should start taking the drug at 20 to 40 mcg/day and continue taking such dosage for 2 to 3 weeks. After this period, the dosage may be increased by another 20 mcg/day. The same dosage must then be taken for another 2 to 3 weeks. This practice should go on until the maximum dosage of Clenbuterol is reached. With this program for Clenbuterol use, the effect of Clenbuterol may be maximized and maintain the enhanced metabolism of the body. Though the improvement in metabolism may not be that much, this effect will persist in a steady and continuous manner.


This particular method of taking Clenbuterol has a period of 4 to 6 weeks and is perfect for individuals who only intend to use the drug as part of their final preparations for a competition. In this program, the user will start at 40 mcg/day and increase the dose after a certain period until the maximum recommended amount is achieved. The final dose will then be taken for a period of one to two weeks. The increase in dosage is not as drastic as the two-week rotation program but it is comparatively better than the continuous one. Moreover, in this final stage, when the individual deems that he needs more dosage of the drug, he must wait for 4 to 6 weeks before he can start another phase. This aspect makes this program perfect for those who only intend to use Clenbuterol for a short period of time.

Despite the various schedule programs for Clenbuterol use, the maximum dosage is more often than not 120 mcg/day. Some men still push the 140 mcg/day mark, but no dares to go beyond that amount to prevent themselves from incurring any cardiac damage. Moreover, no matter type of program they use, people should only settle for 16 weeks of Clenbuterol treatment per year. However, exceptions may be allotted for certain individuals.


People will have no trouble accessing the drug. However, people should be aware of sellers who claim that what they are selling is manufactured in the US because Clenbuterol is produced in other international countries. Suppliers of anabolic steroids usually have Clenbuterol among their stocks, and almost nobody thinks of counterfeiting the this drug. Meanwhile, there are other drug suppliers who also offer Clenbuterol. On the other hand, people can also obtain Clenbuterol illegally as a number of unreliable sources sell the product in the black market or online.

Meanwhile, people may also purchase Clenbuterol from research chemical labs. A number of this type of laboratories have sprung over the years, and they also have the permission to sell chemical compounds, including the likes of Clenbuterol. However, most will sell the product when it will be used for research purposes only. When sold in labs, Clenbuterol usually comes in liquid form. Thus, some individuals use this loophole in the law to acquire Clenbuterol even though they won’t be using the compound for research.


As mentioned, Clenbuterol can be easily bought online. The drug is not considered a controlled substance. However, buying it online is illegal. It may only be bought online for research purposes. On the other hand, though a number of people buy lab-produced Clenbuterol, there are some problems that they may encounter along the way. There are certain labs that manufacture low-quality versions of Clenbuterol. Thus, the effects of such compounds may be reduced or in worse cases, they are ineffective. In other instances, the manufactured Clenbuterol is concentrated, which makes it hard for the user to measure the proper dosage. As a matter of fact, some tested Clenbuterol have concentrations of 200 or 300 mcg//ml. Thus, people should be very careful when buying lab-produced version of the drug.


Clenbuterol is an effective thermogenic product, though people should not think that taking the drug alone is enough to induce weight loss. Proper diet and exercise must still be practiced in order to maximize the effect of this drug. In addition, people can only use the compound to a certain extent, as the body learns to adapt to the drug with prolonged use. As a weight loss agent, Clenbuterol is perfect for those who already near their target weight, as the drug can help in eliminating the remaining stubborn fat in their body. Clenbuterol may also enhance metabolic functions and thus, hasten the process of fat burning. The drug is not considered as controlled substances, though it can still be abused and may also be bought illegally. In short, people must still practice precaution should they decide to use Clenbuterol.
