Clenbuterol fat burners are extremely effective at boosting the metabolism for weight loss. Clen is in the sympathomimetic class of drugs because it stimulates the sympathetic nervous system.

The sympathetic nervous system is what triggers the human “fight or flight” response. This speeds up heart rate, dilates the bronchial muscles, and causes a general stimulant effect which is one of the reasons why they call it clenbuterol fat burners.

It is sometimes prescribed outside the U.S. as an asthma medication. In the United States, it is not considered suitable for human use, and you cannot get a prescription for it. In the past, Clenbuterol was used to beef up livestock, before a metabolite was found to be toxic. Buy Clenbuterol Fat Burners online here. 


Using Clenbuterol Fat Burners

Clenbuterol fat burners stay in the system longer than other similar drugs. Other bronchodilators will leave the system after about four hours, but Clenbuterol stays in the system for at least a day. It is similar to ephedrine but much more potent.

As you can imagine, it also has fat-burning properties. Specifically, it spurs the breakdown of adipose fat in the tissues. A cycle of Clenbuterol fat burners also referred to as “Clen” can help break down triglycerides into fatty acids for oxidation. Fans of Clen use it for rapid weight loss. For bodybuilders, in particular, Clen is attractive because it allows you to lose weight, and get lean but not lose muscle.

It does have anabolic properties. As mentioned earlier, in the past it was used to bulk up livestock. As you might imagine, this may lead to the belief that Clenbuterol is not only a weight-loss drug but a muscle builder as well, the best of both worlds.


While it may have been responsible for increasing muscle in livestock, it doesn’t really do that for humans. The reason comes down to dosage. In order to get the effects that animals did in clinical testing, a human would have to take at least 400 mcg to get this effect.


Clenbuterol Diet Pill Dosages


A common dose of Clenbuterol fat burners for weight loss effect is 60 – 120 mcg daily. Obviously, taking a dose high enough to add muscle to cattle is not advisable for humans. Clen is a powerful drug that has some nasty side effects, and taking an unsafe dose can be lethal.

With that said, taking recommended doses of Clenbuterol does burn fat, and many bodybuilders do maintain that it doesn’t result in loss of muscle. Many Clenbuterol reviews rave about how well you can develop a lean, cut look while still maintaining or even increasing muscle mass. This is a desirable effect, but it is also worth it to know that many bodybuilders who use Clen are also stacking it with other drugs such as Winstrol.

If you are considering Clenbuterol as a fat-burning agent, you need to make sure you have as much information as possible. The drug has serious side effects and can cause irreparable cardiovascular damage.

Clenbuterol Fat Burners And Sports

Clen is not legally prescribed in the United States, and although it is legal in many other countries, it is categorized as a performance-enhancing drug and therefore is illegal in many sports. If you are an athlete who competes, be sure to determine whether taking Clen can result in disqualification, or worse.

Clenbuterol Fat Burners For Women

How To Take Clen Women

Although Clen is often used in the bodybuilding world (by both men and women) it is also used outside of athletics, primarily by women as a rapid weight loss aid. Not long ago, Clen was a huge hit among Hollywood actresses who dubbed it the “Size zero pill.” Just like in men, Clen allows for rapid weight loss.

Side effects apply even if you are not using it for bodybuilding or stacking it with other drugs. A recommended dosage for women is to start with 20 mcg for approximately three weeks. The dose can be built up, but no one should take more than 120 mcg and it is suggested that women don’t do that high of a dose at all.

Overall Review

Clenbuterol is a stimulant similar to ephedrine, but more powerful as a fat burner. It is highly effective as a weight loss supplement that works quickly and doesn’t result in muscle loss. Simply put, it does what it’s supposed to do, and it does it well. Drawbacks to Clen diet pills are that it must be used very carefully and there can be side effects that range from annoying to dangerous, so the utmost caution should be used.

You can buy Clenbuterol in either a pill or syrup form. The syrup is generally sold by research companies, and there have been reports of people purchasing bogus syrup from these researchers or having trouble getting the dosage right. Tablets can be purchased online. The price may vary, depending on what outlet you use to purchase the drug, how many mcg you are purchasing and how many tablets.


More Information About Using Clenbuterol Fat Burners

Because this drug is a stimulant that can result in insomnia and because it increases heart rate, sometimes dramatically, it should be taken in the early morning and should be taken several hours before a workout to avoid muscle fatigue and heart palpitations. Cramping can be caused by taurine depletion, so if you experience this problem, supplementing with taurine should alleviate it.

If you experience side effects with Clen, you should discontinue use immediately and seek medical help. This drug should not be taken long-term, but cycled at the lowest effective dose and monitored closely.

Clenbuterol fat burners do not replace the need to exercise or eat healthily. Whether you are a bodybuilder or a woman looking to lose weight quickly, you should be eating healthy foods, monitoring caloric intake, and getting adequate exercise. But using clenbuterol as a fat burner can help considerably.
