Can Clenbuterol Help Burn Fat? Benefits & Side Effects Revealed


Clenbuterol Hydrochloride was initially created as a bronchodilator within the lungs and was used to treat asthma and certain lung diseases.

It is commonly referred to as ‘Clen’ and it shares many similarities to ephedrine; it is a very effective and potent fat burner. It is usually administered in tablet form and its fat burning potential has made Clen a very popular supplement with research showing that it also has anabolic properties.

This article will discuss how it actually burns and strips your body fat away. However, please be aware that this article does not condone the use of steroids in any form but it will discuss the impact that Clen can have on performance and muscle gains.[toc]

What is Clenbuterol?

As a bronchodilator ‘Clen’ stimulates the Beta 2 receptors and this mechanism actually increases your body’s metabolism.

This rise in your metabolism caused by the Beta 2 receptor stimulation causes an increase in your core body temperature, which is caused by the increased cellular heat.

A key point to consider is that a rise of 1 degree Fahrenheit can lead to an increase in 5% in total calories burnt.

This simple but effective progress can be broken down as follows:

  1. The rise in temperature is caused by the mitochondria (power house) of the cells and they increase the heat production.
  2. This in turns causes a surge in body temperature.
  3. Finally, this will increase your metabolic rate and your fat burning potential.

An increase in metabolic rate caused by Clen can increase the rate that we burn and utilise fat as an energy source.

This increases the rate and efficiency that the body uses the fat as a fuel source and it may also suppress your appetite.

However, this suppression of appetite may not happen to everyone and some athletes don’t experience this effect.

Suppressing your appetite may be seen as a benefit for some bodybuilders, but if your food intake falls below 800 calories per day then your body will start to cannibalise your muscle after it has stripped away your fat.

Therefore, suppressing your appetite especially when bodybuilding maybe seen as counterproductive, as your muscle needs constant feeding of the right macros and enough calories to sustain gains, growth and repair!

Benefits of Clenbuterol

Clen improves cardiovascular efficiency and an increase in our metabolic function.

As mentioned previously, Clen can speed up lipolysis but it can also boost the production of lean body mass.

However, bear in mind that Clen will boost your fat free mass within the body but not to the same extent as an anabolic steroid.

It does have quite mild anabolic attributes and this improvement in your lean body mass can be associated to an increase in protein synthesis.

Research has shown that Clen being present in the body definitely impacts on the activity and efficiency of muscle tissue production, as when Clen was not present in the control group this production slowed right down.

In addition, combine this will its fat burning potential, the rise in metabolic activity and the increase in protein synthesis, then you have one powerful supplement on your hands.

Side effects of Clenbuterol

As with many supplements, Clen does have some unfortunate side effects. Although these side effects do vary from individual to individual, when they do show up they can be problematic.

The most problematic side effects that are caused by it’s stimulating effects are bouts of anxiety, nervousness and insomnia.

However, this is dose dependent and many individuals exhibit another common side effect; cramp.

Research has indicated that certain types of cramp can be counteracted by drinking increased amounts of water.

Your hydration levels should also be monitored rigorously because Clen does increase your sweat rate and many valuable electrolytes are lost in sweat. This can seriously affect your training and muscle building potential.

One of the side effects associated with Clen is high blood pressure. This drug acts as a stimulant; this can increase your resting heart rate and many individuals suffer with palpitations.

A combination of high blood pressure and an increase in resting heart rate could lead to heart failure.

This is caused by the excessive strain placed on the heart by Clen and should be avoided especially if you already have hypertension.

Another very concerning side effects of Clen is that it can be ruthless on the heart. The main issues are that is can cause cardiac hypertrophy and this can lead to shortness of breath, chest pains, light headedness and fainting.

Long term damage can lead to abnormal heart rhythms and blockages in the heart because Clen targets the cardiac and smooth muscle fibres in the heart.

Clenbuterol FAQs: User submitted questions

Below are some questions that have been submitted:

Why has Clenbuterol been banned?

Unsurprisingly, after being discovered to offer performance enhancing benefits the IOC or International Olympic Committee took it upon themselves to ban the use of Clen in athletic competitions.

The World Anti-Doping Agency also added Clenbuterol to their list of performance enhancing drugs and stopped athletes from using it. Subsequently various athletes, including sprinter Katrin Krabbe were banned from competition because of its use.

Due to the risk of side effects, the FDA or US Food and Drug Administration has banned the Clenbuterol for human consumption, even banning the use of Clen in animals that are used for food.

Certain countries allow the use of Clen in animals, with reports showing that adverse reactions are likely.

In 2011, Chinese pig farmers fed Clenbuterol to their animals to increase muscle growth. Humans who then ate this pork encountered side effects such as nausea, headaches and tremors.

Where has Clenbuterol been banned?

While the FDA (US Food and Drug Administration) recommends that Clenbuterol is best avoided, and that it is banned from being used on any animal used as food for human consumption, it is not a controlled substance and can be used without restriction in the USA.

It has however, unsurprisingly been banned for all IOC-tested athletes.

The legality of using and buying Clenbuterol varies from country to country.

In the UK it is classed as a Class C drug, which means that if you intend on buying it with the intention of distributing is illegal.

It is possible to get Clenbuterol in the UK, but only if you are prescribed it for severe asthma.

Clenbuterol is not a controlled substance in Canada, so while it is not approved for human use, it can be purchased overseas and used legally.

In Australia, Clen is illegal to import, sell, or buy for personal use. While in New Zealand, there has been a crack-down on this drug, but while its distribution is difficult, it is legal to use.

Who has been caught using Clenbuterol?

While there have been rumours in Hollywood that celebrities such as Britney Spears, Victoria Beckham, and Lindsay Lohan have used Clenbuterol for weight loss there is little or no proof to back this up.

However, there are numerous examples of sport stars and athletes who have been caught using Clen, such as:

  • Australian heavyweight boxer Lucas “Big Daddy” Browne
  • Carter Ashton, NHL player for the Toronto Maple Leafs
  • Mexican boxer, Erik Morales
  • South Korean swimmer, Kim Ji-Heun
  • Guillermo Mota, pitcher for the MLB team San Francisco Giants

Clenbuterol Dosage Instructions

When you first start taking Clenbuterol it is best to start off with a dosage of 40mcgs daily for men, while women should use just 20mcgs daily.

The reason why you should start off with this lower dosage is to reduce the risk of encountering any complications or side effects.

When it comes to increasing the dosage it is best to do this at the start of a new cycle, which is recommended to be a maximum of 6 weeks on.

It is recommended that men should never exceed 140mcgs daily, with women recommended to stick below 120mcgs.

You should never take Clenbuterol in a cycle longer than 6 weeks, and never should use it for more than 16 weeks per calendar year.

When it comes to choosing between pill and liquid forms, it is advised that you should opt for the pill as it is easier to maintain the correct dosage. Both forms are as effective as each other.

Clenbuterol cycles

There are some experts who claim that to avoid your body building up a tolerance to Clenbuterol that you use a 2-week on, 2-week off cycle.

It is said that the fat burning benefits will last between 6-8 weeks, while the muscle building and muscle retention benefits last around 18 days.

While on the off cycle it is recommended that you use an ECA stack (ephedrine, caffeine, and aspirin).

How long until you see results?

Unlike most anabolic steroids, users of Clen will experience almost immediate effects. Of course, this will vary from person to person.

Which is safer Clenbuterol or T3?

Both T3 and Clenbuterol are able to burn calories, they are both likely to cause side effects too.

One of the major risks associated with T3 use is that it can affect your natural hormone levels, which can potentially lead to thyroid disease and low thyroid output not only during use, but later in life as well.

Which is better Clenbuterol or Albuterol?

While both drugs are beta-2 adrenoceptor agonists, that act as stimulants that can break down fatty acids and increase metabolism.

The main difference between Clenbuterol and Albuterol is that Albuterol has a shorter half-life of just 6 hours (Clen has a half-life of 48 hours).

Having a shorter half-life means that you will need to dose more often, but you will not build up a tolerance to the drug as quickly.

Is Clenbuterol or Anavar better?

When it comes to fat loss Clenbuterol is the better option, however as it is catabolic you may risk losing your hard-earned muscle gains when using it.

Anavar is less effective for fat burning, but you are more likely to maintain muscle mass through its use.

Which is better Clenbuterol or Winstrol?

Clenbuterol is used for burning fat, while Winstrol is best used to maintain muscle while on a low calorie diet (while cutting for example).

Another benefit of Winstrol is that it can harden your muscles and can help you to become more vascular.

Which is better for fat loss Clenbuterol or Ephedrine?

There is one notable difference between Clenbuterol and Ephedrine, one is a drug while one is derived from plants.

Both work in similar ways, and as they are stimulants also offer similar side effects too.

What time of the day to take Clenbuterol?

The best time of day for you to take Clenbuterol is early in the morning, or just before you workout.

If you take it later in the day this could affect your sleep.

How much Taurine should you take alongside Clenbuterol?

Using Clen can cause a reduction in your natural Taurine levels, this can lead to painful muscle cramps.

It is recommended that you consume 3-5g of Taurine daily. This can help reduce the shakes associated with Clen use as well as any heart palpitations.

Taking Clenbuterol when pregnant

Unsurprisingly I would not recommend using Clen while pregnant.

Clen is a stimulant so shouldn’t affect your ability to become pregnant, however as it has a half-life of 48 hours once you discover you are pregnant you must discontinue use immediately.

Why should you use Benadryl with Clenbuterol?

Benadryl contains Diphenhydramine HCL which can extend Clen usage up to 8 weeks, from the usual 6 week cycle.

Why does Clenbuterol make me tired?

This may seem like a contradiction, but it is possible that a stimulant like Clen could speed you up so much that you slow down.

This more commonly seen in those who suffer from ADHD.

A more likely situation for your tiredness is that your diet is not up to scratch. Have a look at what you are eating to ensure you are getting enough nutrients to keep your energy levels high.

Even when cutting you still need to ensure your calorie intake and nutrients are sufficient.

Why does Clenbuterol make me shake?

Like most stimulants, Clen will stimulate your sympathomimetic nervous system (SNS), activating your “fight or flight” response.

This can result in an increase to your heart rate and shaking.

How much fat loss from Clenbuterol?

It is impossible to predict how much fat loss you will experience when using Clenbuterol.

You will also need to factor in your goals, diet and training too.

How long does Clen stay in your system?

Clen has a half-life of 48 hours, but it may take up to 10 days to be completely removed from your system.

Clenbuterol for Women: Is it recommended?

Clenbuterol can be used by both men and women, and while it is effective at burning fat in both sexes the side effects are likely in both too.

Female users of clen are recommended to add some Potassium or Taurine to their stack, as Clenbuterol use has been shown to reduce levels of both minerals.

Consuming 4 apples or oranges daily will suffice, while also ensuring you drink plenty of water too to ensure you do not become dehydrated.

Is Chinese Clenbuterol legal and safe?

Due to Clenbuterol being illegal to buy in many parts of the globe, some maybe tempted to look at other options. Such as buying Clenbuterol online from China or another Asian country.

The problem is that many of these products are fake, and you are not only risking your health using them, but also risking your hard-earned money too.

How to Avoid Fake Clen Pills?

Unfortunately there is a growing number of complaints online from those who have unwittingly bought fake clen pills from offshore pharmacies and steroid stores located in countries such as China, India, South Africa and Mexico.

You may even find counterfeit suppliers of clen closer to home, with some reported scams in the UK, USA, Canada, Australia and other European countries.

While losing money is one concern, buying a fake product will significantly increase the risk of encountering side effects.

These fake products may contain contaminants or undeclared ingredients, and because many countries have lower quality standards than North America and Europe you are putting your health at risk using them.

It is important when looking to buy Clen that you look for a reliable online source that has plenty of online user reviews and customer testimonials.

One of the best options is to look for real Clenbuterol that can be sold online without a prescription, it maybe difficult to find these vendors but certainly not impossible.

Certain countries can sell these “over the counter” breathing remedies and bronchodilator. And these are recommended as they will be made from medical grade quality ingredients, with better quality than most underground labs.

Most Clenbuterol pills are 20mcg per pill (sometimes written as 20ug), however some pills can be found at double strength (40mcg) or even 50mcg pills.

If you find a product with a different dose then chances are this is a fake and is best avoided.

Sometimes you will come across pills with a much higher dose, for example 100mcg or 200 mcg, but these are designed for veterinary use, so should not be used.

Most pills found online will be white, the natural colour of Clenbuterol. However, sometimes a colouring agent will be added.

Liquid Clen, which can be used as an injectable will usually be found in 200mgc/mL doses, sold as 30mL vials.

You need to be on the look out for these fakes and to only purchase from legitimate vendors with a good reputation, with a long history or user satisfaction.

Comparing photos of any Clenbuterol pills you receive with photos from online forums will be your last way to check if the product you have purchased is authentic.

Where can you buy Clenbuterol?

There are plenty of places online where you can buy Clen, the problem is that many places will sell fake versions that are likely to cause harm.

I would be wary about buying Clenbuterol online from an unverified source. It maybe a better idea to speak to someone you know at your local gym that you know uses anabolic steroids. You can then get a recommendation for purchasing.

With the risk of side effects that are possible from the use of Clen, why would you take the risk? Especially when there are safe and legal alternatives available, please read on to discover which product we would recommend.
