Clenbuterol Why People Use It

Clenbuterol Uses, Benefits and Side Effects

Clenbuterol -from the Latin Clenbuterolum- is a sympathomimetic amine (stimulant drug) that is commonly used in medical and veterinary fields to treat breathing disorders.

Also famously known as just “Clen”, Clenbuterol functions both as a powerful decongestant and as a bronchodilator.

As a decongestant, Clenbuterol thins the blood and minimizes pressure to reduce inflammation and swelling.

Clenbuterol Tablets

As a bronchodilator, it relaxes the muscles and widens the oxygen-carrying vessels; making breathing easier.

The potent drug has been the subject of much controversy. Although legal in certain countries around the world – its use is mostly prohibited in both the USA and the European Union.

Scientifically, Clenbuterol is a beta-2 agonist. This means that it produces short-term effects similar to those of a stimulant. Its biological half-life is calculated to be approximately 36-48 hours.

Is Clenbuterol Legal?

The legal state of Clenbuterol is quite interesting.

As it was previously mentioned, the legality of the drug will greatly depend on the country – and its intended use.

Its use in humans is strictly prohibited in China, the USA, and the European Union.

Interestingly enough, it’s completely legal to buy Clen for personal use in Canada and the UK.

Whereas some countries allow its use in horses to treat allergic respiratory diseases; the drug is strictly prohibited from being used in livestock.

Is Clenbuterol an Anabolic Steroid?

Clenbuterol isn’t technically a steroid. Although, most people will wrongfully categorize it as such, due to its anabolic properties.

Athletes, bodybuilders, and even celebrities have been using Clen for years. Mostly, because it offers a simple way to enhance the body’s physical appearance and athletic performance.

Because of this -and despite its illegal nature- Clenbuterol has gone on to be one of the most popular thermogenic anabolic compounds in the world.

And, why wouldn’t it be? In the eyes of many, it’s a miracle pill that can transform the appearance of the human body with minimal effort.

Sadly, this couldn’t be farther away from the truth.

As the saying goes – if it sounds too good to be true, it probably is.

What are the Benefits of using Clenbuterol?

Clenbuterol can stimulate both the cardiovascular and the central nervous systems.

This, because Clen is a beta-2 agonist that acts similarly to epinephrine and other potent amphetamines.

As soon as the drug enters the bloodstream, it stimulates the cells into producing and releasing more heat.

Once the body raises its internal temperature; calories are burned more efficiently and the metabolism begins to function at a faster pace.

Clenbuterol Benefits:

  • Higher Body Temperature
  • Accelerated Fat Burning
  • Enhanced Energy Levels
  • Improved Aerobic Capacity
  • Increased Basal Metabolic Rate (BMR)
  • Enhanced Oxygen Transportation

Clenbuterol Medical Uses

Clenbuterol is commonly used in the medical field to control asthma symptoms.

Patients generally receive a recommended dosage of 0.02 or 0.03 milligrams per day; that’s administered either through an inhaler or in tablet form.

Asthma Inhaler

Like most bronchodilators that are used to treat serious breathing conditions – Clenbuterol should only be used as needed; opposed to daily use.

It’s worth noting that the potential health risks associated with the drug have led most medical professionals to discontinue its use – and instead prescribe other forms of medication.

Clenbuterol for Bodybuilding

Bodybuilders and athletes are undoubtedly the biggest consumers of anabolic steroids in the world.

Although Clen isn’t technically a steroid – its benefits say otherwise for the growing community of men and women that use it.

It’s a known fact that Clen has been a staple in both the bulking and cutting cycles of professional athletes, for decades.

It’s believed that while bulking, Clen can help the athlete build more muscle and develop greater strength levels; while maintaining (or even reducing) the body’s fat percentage.

As far as cutting goes, Clenbuterol can (potentially) make the dieting process a lot easier by accelerating and maximizing the body’s ability to break down fat; when it’s in a caloric deficit.

Clen is also believed to protect the muscle fibers from losing size while the fat cells are being continuously broken down.

Clenbuterol for Weight Loss

Surprisingly enough, “cutting cycles” are only the beginning of Clenbuterol’s popularity. Outside of bodybuilding, there’s a huge market for Clenbuterol as a weight loss solution.

Its thermogenic properties and fast-acting abilities have tempted athletes and celebrities from all over the world to use it.

Hollywood is just the tip of the iceberg though; because Clenbuterol’s widespread use doesn’t quite stop there.

Individuals with little athletic/bodybuilding experience have been known to experiment with the dangerous drug; in an attempt to transform their physique’s appearance.

Before and After Clenbuterol

What many of these people don’t seem to realize is that Clenbuterol won’t help them lose weight.

Why? Because Clen isn’t a magic pill and it only works under very specific circumstances.

For the drug to work, the person who uses it must already have low body fat levels – achieved through proper training and nutrition.

Someone who is overweight will only find Clenbuterol to be counterproductive and dangerous.

Clenbuterol for Women

Clenbuterol’s anabolic background would lead most people to believe that its biggest target group (bodybuilding) is men – when it’s the opposite.

Female bodybuilders and athletes have been using the compound for years; due to its alleged performance-enhancing benefits.

Women often consider Clenbuterol to be a superior alternative to that of popular cutting steroids -such as Winstrol or Trenbolone- because it’s believed to be less aggressive.

Female Fitness Model Posing

It’s common knowledge that anabolic steroids can generate a long list of side effects that are often irreversible.

Women are often more vulnerable to these side effects than men and therefore tend to be a lot more careful about their steroid selection.

Female athletes believe that they can get a lot closer to their fitness objectives -while eliminating a lot of these concerns- by using Clen.

Androgenic Side Effects of Steroids in Women:

  • Acne
  • Hair Loss (Balding)
  • Voice Deepening
  • Facial Hair Growth
  • Clitoromegaly
  • High Cholesterol
  • Bloating
  • Organ Damage

Female bodybuilders commonly use Clenbuterol nearing a bodybuilding competition, so they can get rid of that last bit of body fat that blocks their physique’s definition.

On top of this, it’s believed that the drug allows them to gain strength and lose body fat without sacrificing their hard-earned muscle mass.

Clenbuterol Use in Hollywood

As it was already briefly mentioned, Hollywood is one of the most notable consumers of the famous thermogenic stimulant.

Have you ever wondered how your favorite actor or actress got in shape so fast for a specific role? Chances are that they had some help from anabolic steroids.

Just like athletes, celebrities are always looking for that extra competitive edge that’s needed to land the next big role.

Although most won’t admit to it, there are a few rare cases in which celebrities have been accused of using performance-enhancing drugs.

Celebrities That Have Used Clenbuterol:

  • Nicole Ritchie
  • Lindsay Lohan
  • Britney Spears
  • Victoria Beckham

Clenbuterol Use in Sports

The world of sports has been plagued with many Clenbuterol controversies over the years; with many athletes testing positive for the drug.

Even though it doesn’t do much in the way of extreme weight loss and muscle building – a lot of people choose to use Clen for its performance-enhancing abilities.

Some of the biggest Clenbuterol users come from sports that require high levels of cardiovascular endurance. These include boxers, runners, baseball players, soccer players, cyclists, etc.

Whereas bodybuilders use it to lean out and get ready for competition; athletes use it to enhance their performance, improve their breathing, and to preserve muscle as they practice strenuous levels of physical activity.

Is Clenbuterol Allowed in Sports?

No, Clenbuterol is a banned substance in most athletic federations across the world; including the International Olympic Committee (IOC) and the World Anti-Doping Agency (WADA).

Although most powerlifting and bodybuilding federations are also against the use of Clenbuterol; a loose grip on testing suggests that its use is a common occurrence.

Athlete Sprinting

The Mr. Olympia – also known as the Super Bowl of bodybuilding – has only been drug tested once since its creation in 1965.

Why once? Because the only year that it was tested (1990) resulted in a complete disaster.

In order for the athletes to pass the doping tests, they had to lower/discontinue their steroid use shortly before the competition.

This led them to look a lot less impressive than they had in previous years – which greatly disappointed the fans in attendance.

As soon as the show finished, it was clear that bodybuilding and doping did not go well together. Since then, drug tests -in that specific bodybuilding federation- are extremely rare.

Mainstream sports are a completely different story, though. With more than a fair share of athletes having tested positive for the drug.

Famous Clenbuterol Doping Cases

The biggest problem with Clenbuterol -and the main reason that athletes use it- is its blatant use in livestock.

Nowadays, it’s very difficult to know for sure if someone was being administered Clenbuterol as a PED (performance-enhancing drug) or if it was consumed indirectly through the consumption of contaminated meat.

The most recent case is that of Canelo Alvarez. The professional boxer tested positive for Clen on two occasions, early this year.

Because of Clen’s widespread use in livestock across Mexico; it’s impossible to know for sure if Canelo tested positive as a direct result of consuming contaminated beef.

Athletes That Have Tested Positive for Clen:

  • Katrin Krabbe – Sprinting
  • Jessica Hardy– Swimming
  • Guillermo Mota – Baseball
  • Alberto Contador– Cycling
  • Mexico’s National Football Team – Soccer
  • Erik Morales – Boxing
  • Carter Ashton – Hockey
  • Canelo Alvarez– Boxing

How is Clenbuterol Administered?

Clenbuterol can be used either orally or intravenously; with the first being the most common form of administration.

In human use, the drug is readily available either as a tablet or as an inhaler. Veterinary Clenbuterol is administered in liquid form.

How is Clenbuterol Tested?

Like most PEDs, Clenbuterol is most commonly tested by performing a doping test in which the urine is analyzed for leftover traces of the drug.

Urine isn’t the most effective form of testing; because the drug is only detectable for less than a week.

The second form of testing is done by analyzing hair follicles. Sadly, it’s just as inaccurate as the urine test for a completely different reason.

Whereas urine tests can only catch traces of the drug after a short period – follicle testing is very inaccurate in general and can throw random results, that are either really high or very low.

Clenbuterol Cycle and Dosages

In order to maximize the effects of Clenbuterol, it must be cycled properly.

To do this, the user must have full control over the dosages -and the frequency- in which the compound will be administered.

According to different online sources, most individuals will start their Clenbuterol cycles with 0.04 milligrams per day; although women may feel comfortable starting at 0.02 milligrams per day.

It’s also mentioned that there are four types of cycles that are commonly used by athletes to take full advantage of the compound’s benefits.

Pyramid Cycle

The most popular cycle consists of using the drug for two weeks on, followed by two weeks off.

During this cycle, the person will start with the lowest possible dose and increase it intelligently every few days – until they’ve reached the desired/maximum dose.

The maximum dose is maintained for the last few days -until the two weeks are up- only two discontinue its use entirely, for two more weeks.

The process is then repeated, starting with the final dose that the previous two weeks ended with.

The dosage range will vary depending on the person’s experience with the substance. Someone with less experience will arguably require a lower dose than someone who uses it frequently.

Pyramid Cycle Example:

Clen Pyrimid Cycle

Continuous Cycle

The second type of cycle consists of administering Clen continuously. Meaning that there’s no break whatsoever during its use.

People typically begin this cycle with the generic starting dosage (0.02-0.04 milligrams) and maintain it for 2-3 weeks.

At the end of the period, the dose is increased by another 0.02 milligrams and held there for the same period (2-3 weeks).

Continuous Cycle Example:

Clenbuterol Continuous Cycle


Pre-Contest Cycle

The third type of cycle is usually run pre-contest by bodybuilders and falls somewhere between the other two.

For this cycle, the bodybuilder begins with the lowest dosage possible and increases it consistently every few days – until the maximum daily dose is achieved.

The individual will then hold the maximum dose for the last week or two, leading up to the contest.

Once the contest is over, Clen is discontinued for at least 4-6 weeks.

Pre-Contest Cycle Example:

Pre-contest cycle

Blast Cycle

Also known as the two days on/two days off cycle. To do this, the person chooses a moderate dose and uses it for two days; only to discontinue it right after, for the same amount of time (two days).

The process is then repeated until the desired results are achieved – which can last up to a couple of months.

On paper, the blast cycle is probably the easiest of the bunch to follow. Sadly, it also appears to be the most inefficient one of them all.

Following a cycle such as this one will arguably produce mediocre results and can potentially place a lot of unnecessary stress on the body.

Blast Cycle Example:

Clen Blast Cycle Example

Which Cycle is Better?

Choosing the right cycle will all depend on the person’s objective.

Most experts would agree that a blast cycle is rather ineffective and can place a lot of stress on the body.

The pre-contest and continuous cycles are both very effective but also quite aggressive.

Lastly, the pyramid cycle is not as aggressive as the previous two – but it’s widely considered to be safer and just as effective.

Ultimately, it’s important to remember that cycling with Clenbuterol is illegal and very dangerous, under any circumstance.

The only reason that cycles were discussed is purely for informational purposes.


Clenbuterol is extremely dangerous and can cause irreversible damage to the human body.

Therefore, it should never be used under any circumstance; unless it’s prescribed by a medical professional.

Warning Banner

Surpassing 120mcg per day can cause serious -and irreversible- cardiovascular damage.

Its use should also never exceed 16 weeks per year.

Clenbuterol Supplementation

Those who use Clenbuterol need to undergo a calculated supplementation plan in order to minimize the drug’s damage.

Clenbuterol has been scientifically proven to drastically lower the Taurine levels in the heart and other important organs such as the lungs.

This is very concerning due to the fact that Taurine plays a very important role in protecting tissues; especially the heart.

Clenbuterol is commonly known to cause serious muscle cramps and that’s why it’s strongly suggested to consume adequate amounts of potassium to counteract these effects.

Clenbuterol Results

Even though it’s illegal and harmful to the human body; some people will probably still keep on using Clenbuterol to reach their fitness-related goals.

As bodybuilding grows larger, so does the demand for the powerful thermogenic.

Men and women are continuously looking for the easiest way to lose weight and build an impressive physique, without putting in the work

The thing about Clenbuterol though, is that it doesn’t offer drastic results.

Sure, it’s strong and it can help you lose body fat. But, it won’t transform you into a ripped professional bodybuilder.

Clenbuterol does everything that research has proven it to do. But, it doesn’t do it to the level that most people expect it to.

Remember that it isn’t a steroid – it’s a chemical compound with thermogenic properties. This means that it only excels at breaking down fat and burning calories.

Although some people believe that Clen can actually preserve and build muscle; there isn’t any concrete evidence to back up these claims.

Plus, as a weight loss agent, Clen won’t really do much. That’s why most bodybuilders only use it in the last few weeks leading up to a competition.

Clen is only useful for eliminating the last bit of body fat that won’t go away with diet and exercise.

Clenbuterol Side Effects

Clen is no stranger to controversy as it’s banned in several countries around the world.

It’s important to remember that Clenbuterol is -after all- a powerful stimulant.

Although beneficial in some scenarios, the drug has also been known to generate its fair share of negative side effects.

Clen Side Effects Image

Common Clenbuterol Side Effects:

  • Headaches
  • Trouble Sleeping
  • Loss of Appetite
  • Sweating
  • Anxiety
  • Tachycardia
  • Nervousness
  • High Blood Pressure
  • Muscle Cramps

When Clenbuterol is administered medically; patients with a chronic breathing disorder, such as asthma, will rarely exceed 0.02 milligrams per day.

A moderate dose helps the patients manage their discomfort while keeping the potential side effects low.

As you can probably tell from the cycles mentioned above, athletes are a completely different story because they tend to frequently abuse Clenbuterol.

This places them at a higher risk of suffering from the previously-mentioned side effects… and a few others that are worth mentioning.

Other Potential Clenbuterol Health Risks:

  • Panic
  • Trembling
  • A decline in Bone Mineral Density
  • Cardiac Hypertrophy
  • Cardiac Necrosis
  • Thyrotoxicosis
  • Liver Damage
  • Death

Clenbuterol User Experiences

There’s no better way to understand how Clenbuterol works than by visiting the different online steroid forums and reading up on the different user experiences from the active members.

Some of these forums date back decades and are filled with a ton of valuable first-hand information from individuals that have experimented with Clenbuterol and other anabolic compounds.

In general, the common sentiment is that Clenbuterol is very dangerous and not worth the risk.

Advanced bodybuilders with prior experience with anabolics have been more than happy to share their experiences with the powerful thermogenic.

Most user experiences point to the fact that Clenbuterol is pretty much useless as a weight-loss compound.

Why? Because its only function is that of accelerating the body’s metabolism and improving thermogenesis.

The benefits of Clenbuterol can be experienced naturally without ever having to get near the banned substance.

A proper diet and a strict workout program are more than enough to lose weight and improve one’s physique.

Clen User Experience

If we add cardio training and a healthy supplement regime into the equation; these results can be that much greater while being 100% healthy.

Those who practice a demanding sport will also want to stay away from it, for obvious reasons.

Past Experience Using Clen

Regardless of its performance-enhancing properties; Clen will undoubtedly take a huge toll on the person’s health.

There’s a reason that Clen is a banned substance.

Clenbuterol in Mainstream Media

One of the biggest factors that played a significant role in Clenbuterol’s popularity is its coverage in the mainstream media.

Newspapers, gossip magazines, and online blogs couldn’t stop talking about the world’s latest magic pill that celebrities were using to transform their bodies.

The media was talking about Clenbuterol like it was the world’s best-kept weight loss secret – and people ate it up.

Clenbuterol Celebrities

Regardless of the fact that these social outlets also commented on the possible dangers of using Clen – it didn’t stop society from being overwhelmed with curiosity.

The fact that celebrities like Victoria Beckham and Britney Spears were apparently using Clenbuterol, sparked an interest that skyrocketed the drug’s popularity.

The end result? A large demand for a “weight loss drug” that doesn’t actually help people lose weight.

Where Can You Buy Clenbuterol?

You would think that a dangerous compound such as Clenbuterol would be very difficult to get a hold of – but that’s not the case.

It’s actually fairly easy for anyone to buy clenbuterol online – which is quite scary.

It’s important to remember that Clen is a banned substance. Purchasing it for recreational use (bodybuilding, weight loss, etc.) can get you into a lot of trouble.

It’s also quite difficult to find a manufacturer that’s selling a legitimate product. Most Clenbuterol pills will be underdosed or cheap rip-offs.

Lastly, the side effects that it produces far outweigh the possible benefits. There are truly better alternatives out there that are affordable, legal, and completely safe to use.

Is Clenbuterol Worth the Risk?

The answer to this question will all depend on who you ask.

Some professional athletes will probably tell you that it’s definitely worth it. The same will go for celebrities and individuals that rely on their physical appearance to make a living.

With that being said, the potential side effects of Clenbuterol will never be worth the risk.

Although Clenbuterol can potentially help you lose a little bit of weight – its overall impact on weight loss and performance enhancement is truly minimal.

In order for anyone to see results with Clen, they’ll have to diet and train extremely hard to see any type of significant physical changes.

Professional bodybuilders use Clen to drop down to extreme levels of body fat (6%) once they are already close to that number.

Those who are thinking of using it to lose weight won’t really get much out of it and are better off eating healthy, exercising, and using a quality supplement.

Is There Such a Thing as a Safe Clenbuterol Alternative?

Yes, there are plenty of safe clenbuterol alternatives out there that are being used by bodybuilders and other types of athletes to reach their physical goals.

Considering that Clen is nothing more than a drug used for final touches; people who want to lose weight and build muscle won’t really benefit much from it in the first place.

In that sense, supplements and legal steroids are a superior alternative to that of the steroid.

Remember that Clenbuterol really isn’t what it’s made out to be as it doesn’t actually work very well for weight loss.

It only shines when it’s used for cutting; once someone is already very lean.

Even if you’re already shredded, you’ll still need to diet and train just as hard for the compound to work.

These facts have understandably led a large number of people to substitute Clen for a natural alternative that’s both safer and a lot more effective for bodybuilding-related purposes.

Legal Clenbuterol

If you are trying to lose weight and get in shape, you might be interested in trying a legal Clenbuterol alternative.

Bodybuilders have grown tired of using anabolic steroids and other dangerous compounds -such as Clen- and have instead shifted their focus towards quality supplements and legal steroids.

Legal steroids strive to mimic the positive effects of anabolic steroids without generating any negative side effects whatsoever.

These products are 100% natural, side-effect free, and can be purchased legally online without a prescription.

Many legal steroid companies have spent a lot of time and resources trying to develop the best form of legal clenbuterol that’s humanly possible.

Sadly, only a handful have succeeded at creating a formula that can rival the powerful thermogenic.

The most popular Clenbuterol alternative is Crazy Bulk’s Clenbutrol it is just one of the companies top sellers because of its potent fat burning ingredients.

Clenbuterol is a stimulant with anabolic properties that’s been used for its performance-enhancing properties.

Its thermogenic and fat-burning properties have wrongfully led a lot of people to believe that it’s a powerful fat loss compound.

The reality is that Clen only offers noticeable benefits in those who already possess extremely low levels of body fat and that practice an active lifestyle combined with a structured diet.

Bodybuilders and other types of athletes have used the drug in an attempt to improve their breathing and physical performance while maintaining their physiques in a lean state.

Celebrities have also used it to get into shape – being scrutinized by the mainstream media. This has sparked an interest in general society and has led uninformed individuals to make the dangerous decision of using this drug.

even though there’s plenty of evidence supporting Clen’s thermogenic and fat-burning properties; these have been proven to be minimal.

Experience athletes claim that an active lifestyle and a small caloric reduction offer the same results to that of using Clenbuterol – questioning the reason why people use/abuse the drug in the first place.

Those who abuse the compound can potentially suffer a series of health risks that can be as mild as panic attacks and as severe as organ damage.

For this reason, it’s highly recommended to stay away from the banned substance and instead focus on improving the body’s physical appearance naturally through diet, exercise, and legal form of clenbuterol that possesses no health risk whatsoever.
