Clenbuterol cycle simply refers to the period you are on Clen supplements. For the best results, you need to choose the cycle that is best for you, and one that is in line with your set goals.

There are 3 common types of Clenbuterol cycles that we are going to discuss in detail. It’s upon you to decide which one you’d like to use.

We also look at the types of Clen on the market today, their benefits, results, side effects and how to avoid those side effects.

What is Clenbuterol?

Clenbuterol cycle

As defined by Wikipedia, Clenbuterol, also known as Ventipulmin, Spiropent or Dilaterol, was, and is still being used as a veterinary drug for treating respiratory disease in horses. [1] Some farmers also used Clenbuterol on beef cattle to help the animals increase lean weight.

After years of its usage in veterinary medicine, it was also tested on humans and the results were quite impressive. It was capable of giving the same results as with the animals and was therefore adopted as remedy for human respiratory diseases such as asthma.

Bodybuilders and athletes also began using it to enhance performance. It is mainly used for cutting cycles to sculpt out a perfect, well shredded physique. Clen is also an awesome energy booster.

Clenbuterol usage is however prohibited in most countries, especially in the United States and the UK. In the US, it is banned by the Food and Drug administration and can only be obtained under a doctor’s prescription.

Thankfully, Clenbuterol is legal in countries such as Mexico. There are numerous online Clen dealers in those countries where most people order their supplements from.

Is clen a Steroid?

The common question that most people ask is whether Clenbuterol is actually an anabolic steroid. Since Clen is often associated with commonly abused steroids such as Anavar and Winstrol, it creates the perception in people’s minds that it’s a steroid. But the truth is, Clenbuterol is not a steroid, though it possesses some characteristics akin to those of steroids.

Clenbuterol is actually a stimulant just like coffee but more powerful. It stimulates the beta-2 receptor cells located in your bronchioles and arteries to enhance vasodilation.

This allows more blood to flow to the tissues, thereby ensuring enough oxygen is delivered to the cells– hence more respiration and more energy generated.

Besides, Clen is also known to increase your basic metabolic rate (BMR) to accelerate metabolism of fats. This property makes it one of the best illegal weight loss supplements on the market. Other benefits of Clenbuterol are:

  • It suppresses appetite therefore enabling you to overcome food cravings. This way, you will be able to stick to the right diet plan while avoiding unhealthy foods that can add you more fat.
  • Increases lean muscle growth by enhancing deliver of nutrients to the muscle cells.
  • Eliminates fatigue to help you endure harder at the gym, perform more reps and gain more.

Types of Clen

There are 3 main types of Clen namely powdered Clen, Pills and Liquid clen. Liquid clen should be drunk only!

Powdered clen can be dissolved in water or alcohol and injected, while pills are taken orally. Most bodybuilders prefer pills since they require no expertise in preparation and administration.

Preparation and injection of Clenbuterol can be troublesome, especially for beginners. Thus, we strongly recommend the pills/tablets.

Clenbuterol Cycle

As aforementioned, there are three types of Clenbuterol cycles. The cycle length will depend on your bodybuilding goal.

  • The 2 day on/2 day off Clenbuterol Cycle

This cycle is also referred to as the bursting Clenbuterol cycle. [2] The method involves taking a fairly high dosage of Clen for 2 days, then stopping for another 2 days, then repeating the cycle.

It is one of the most ineffective and dangerous methods of cycling Clen because of the initial high dosage that may be straining to the body, especially if you are not used to the drug.

Lack of consistency also (due to 2-day breaks) reduces the effectiveness of the supplement. Consistency is key to realizing maximum benefits from Clenbuterol.

  • The 2 week on/ 2 week off Clenbuterol Cycle

The 2 week off/2 week on cycle is the most common Clen cycle in use today. It is by far the most effective method.

The idea here is to begin with a small dose (normally 20 or 40 mcg). You will then increase the dosage by small quantities daily, whilst being careful not to exceed the maximum recommended range which is 100-140 mcg.

The increments should go on for two weeks, then stop for 2 weeks, then repeat the cycle. So in short, you are on the drug for a full 2 weeks then 2 weeks off.

The consistency given by this method sees to it that your body reaps maximum benefits from Clen. Starting with a small dose and then stepping up slowly allows the body to adjust and adapt to the drug. This reduces the chance of experiencing side effects.

  • The Incrementing Clenbuterol Cycle

The incrementing cycle is simply an improvement of the 2 week on/2 week off cycle. Just like its counterpart, you will begin with a small dose of between 20-40 mcg, and increase by 20 mcg every two weeks.

The only unique thing with incrementing cycle is that there are no breaks in between. You consume the Clen continuously until you achieve your goals. It is by far the most effective method.

Clenbuterol for Women

Since women are not muscular in nature, it is extremely difficult for them to build muscle. If you are a woman and have been exercising and dieting for long without progress, then it’s time to consider supplementing.

Clenbuterol is one supplement that is so popular with women due to its effectiveness in obliterating belly fat.

Another reason why women prefer Clen is because it doesn’t have androgenic effects like some steroids do.  Provided it isn’t misused, it will work for females just as it does for men.

N.B. even though Clenbuterol works perfectly well to enable you to reach your goals, it is important to note that its side effects outweigh the benefits. Keep on reading to learn how you can avoid those ill effects.

How to Lose Weight fast with Clenbuterol

Some people imagine that they can stop exercising and following a weight loss diet program because Clen will take care of everything. This is a huge mistake. Clenbuterol is not a magic pill.

You need to continue working hard even when taking Clenbuterol or any other bodybuilding supplement. Why? Because Clen only acts as a catalyst to speed up the process. It will not do everything by itself.

Hence, to lose weight fast with Clenbuterol, you need a great weight loss exercise and diet plan. Weight training and strength training are the best exercises to begin with.

Unhealthy, junk foods should be avoided altogether and substituted with low calorie foods. Below are the best weight loss foods that can be used with Clenbuterol for rapid results:

  • Broccoli
  • Kidney beans
  • Almonds
  • Salmond
  • Bananas
  • Green Tea
  • Eggs
  • Peanuts
  • Coffee
  • Lentils
  • Oats

Clenbuterol Dosage

Before you start using Clen, you first need to know the correct dosage. [3] If you ramp up the dosage too quickly, the result may be quite unpleasant for you.

A novice user should start with a small dose of say 20 mcg, and then increase gradually as the body gets accustomed.

The maximum dosage is 100-140 mcg. Experienced bodybuilders in competition sometimes go past this, however research has shown that exceeding the dosage has no added benefit-in fact it increases the risk of horrible side effects.

Another point to consider is the maximum Clenbuterol cycle length. The highest duration recommended by experts is 12 weeks, irrespective of the cycling method you choose.

N.B. Since Clen is illegal, these dosing recommendations are gathered from experienced users and not professional doctors or reliable clinical research. It is therefore important to consult your doctor, where possible, before attempting Clen.

Stacking Clenbuterol

Clenbuterol is normally stacked with steroids such as Anavar and Winsol to enhance its anabolic effects. Stacking therefore means combining more than one supplement at a go.

While stacking amplifies the effects of Clen, it is not a good idea to do so if you aren’t an avid steroid user. Why? Because steroids are hard on the body. You need to first adapt to Clen before attempting to stack it with steroids.

Starting with a small dose of Clenbuterol, you will have to scale up slowly until your body can withstand the maximum recommended dosage (100-140 mcg). At that point your body will be well attuned to its effects and you can then introduce a steroid such as Winsol to augment your gains further.

Another thing to keep in mind is that different steroidal supplements have different dosages and side effects, hence the need to learn about them ahead of time. Stacking inappropriately can result in perilous repercussions.

Clenbuterol Results: Before and After

Clenbuterol results

One thing you need to keep in mind is that exercise and diet come before supplements. Short cuts are unnecessary, and thus, Clen should only come in when you’ve worked hard enough but not seeing any improvements.

Furthermore, Clenbuterol only helps you to reach your goal, and without a proper diet plan it might fail to work. You need to ensure that you cut down on the number of calories you ingest.

Well, if you do all the exercises reduce the calorie intake and supplement with Clen, results will surely be mind-blowing. You will be able to attain that hard toned, well-defined physique that you’ve always yearned for.

Where to Buy Clenbuterol

As mentioned earlier, Clen is illegal in most countries. Most people order it online from countries where it is legally available such as Mexico.

If you decide to order it online, you need to be careful because you don’t want to get in trouble. This will solely depend on the laws of your country.

If you live in the US, we would advise that you go for the legal version instead. Merits of legal Clen include:

  • It won’t land you in trouble for breaking the law
  • It is safe and free from all the side effects of Clenbuterol. Click here to learn more about legal Clen.

Clenbuterol Side Effects

Clenbuterol is a stimulant, and since its traits are similar to those of anabolic steroids, it also harbors a fair bit of side effects.

Clenbuterol side effects list is inexhaustible, but we’ve tried our best to compile the most common ones. There are two main types of Clenbuterol side effects i.e. the short term and long time side effects.

The short term side effects normally occur over the period when one is on Clen (cycle) and are generally mild and manageable.

Long term side effects on the other hand are mainly experienced long after stopping Clen usage. They are severe and can be fatal.

Short-term Clenbuterol Side Effects

Short term side effects are less severe and will usually go away as your body gets accustomed to the drug. However, if you notice multiple side effects you should stop Clen usage for some time.

If the symptoms persist, seek medical help asap. Below are the short term side effects of Clenbuterol:

  • Migraines
  • Racing heart
  • Nausea
  • Vomiting
  • Insomnia
  • Shortness of breath
  • High blood pressure
  • Anxiety and Nervousness
  • Fluttering feelings (palpitations)
  • Too much sweating
  • Tremor and shakiness
  • Severe cramping of the muscles

Long-Term Clenbuterol Side Effects

One of the common long-term side effects of Clenbuterol is heart failure. Irregular heartbeat, otherwise referred to as dysrhythmia is a common problem among Clen abusers, and anything that is capable of altering your heart’s rhythm will eventually shut it down.

How does irregular heart rhythm occur? Clenbuterol causes heart muscle to become stiff and unable to contract normally. This results in irregular contractions as the heart tries to make sure blood circulation throughout the body is maintained.

Clenbuterol also causes cell death in the heart, a slow process that eventually results in a fatal heart failure. Additionally, Clen is known to exacerbate the problems for those already suffering from heart disease.

Besides heart problems, Clenbuterol is also known to affect the thyroid gland. The thyroid is an organ located at the base of your neck and is responsible for secreting hormones that regulate metabolism.

When the thyroid malfunctions due to Clen, it can either release excess or very little hormone. When excess hormone is released, your metabolism may go through the roof and you will keep losing weight even after you’ve stopped taking Clenbuterol. This can be dangerous and difficult to undo.

In case the thyroid malfunctions and releases inadequate hormone, metabolism slows down and you might start gaining weight instead of losing it. In such a case, even diet and exercise won’t change anything. Your weight gain will simply be out of control.

For people who have liver or kidney problems, Clen may not be the ideal weight loss supplement for you. Reason being that Clen makes these organs to malfunction.

Since they are the most important organs for detoxifying your body, hindering their normal functioning could lead to serious complications.

What Happens When You Exceed the Dosage?

Clenbuterol is an extremely powerful supplement and therefore overdosing it could result in serious side effects.

And since Clenbuterol lasts long in your body, the toxicity will persist and get worse with time. Below are some of the consequences that come with heavy doses of Clen:

  • Acute nausea and vomiting
  • Hypotension (dangerously low blood pressure)
  • Stroke
  • Breathing problems
  • Vertigo

How to Avoid Clenbuterol Side Effects

The good news is that the above mentioned side effects can be easily averted if precautions are taken before and while on the drug. Below are some of the preventive measures:

  • Go for Legal Clen Instead

There are natural Clenbuterol alternatives on the market that are as potent as Clen but without the hazardous side effects. One of them is Crazy Bulk’s Clenbutrol, a plant-derived legal alternative of Clenbuterol (note the difference in spelling).

Clenbutrol is derived from popular weight loss plants such as Garcinia Cambogia, Citrus Aurantium and Guarana.

Since it is safer than Clenbuterol, you can cycle it as much as you can or even stack it with other legal steroids such as Anvarol and Winsol. Legal Clen generally comes in the following forms:

  1. Stand Alone

A single stand alone legal Clen sold by Crazy Bulk is just as effective as the original Clenbuterol. It is not only effective but affordable and legal, meaning you can order it online anytime and at any place without contravening the law. For more on Legal Clen, read our Clenbutrol review.

  1. Cutting Stack

The cutting stack is a powerful weight loss formula comprising Clenbutrol, Anvarol (legal Anavar), Winsol (legal Winstrol) and Testo-Max (Legal Sustanon). You can read our full Cutting Stack review here.

  1. Ultimate Stack

The Ultimate Stack comprise Clenbutrol, D-Bal (Legal Dianabol), Testo-Max, Decaduro (legal Deca-Durabolin), Trenorol (legal Trenbolone) and Anadrole (legal Anadrol).

It is the best stack for cutting and for increasing muscle mass. Learn more by reading our Crazy Bulk Ultimate Stack review.

  • Make Sure You Are Healthy

If you’ve had problems with your heart, it’s better to re-think your decision to use Clenbuterol as it can increase the risk of heart attack.

Thus, it is ideal to ensure that you are free from all forms of cardiovascular diseases before attempting Clenbuterol.

  • Take it in Low Doses

The problem often arises when people start with a high dose or increase the dosage too quickly in an attempt to achieve insane gains.

To avoid side effects, you need to start with a low dosage and increase gradually until the body can withstand the effects.

  • Don’t Exceed the Maximum Dosage

It is important to not exceed the maximum dosage that your body can tolerate. Women should not go past 100 mcg. Men, irrespective of their level of experience should never exceed 140 mcg.


In spite of all the side effects, Clenbuterol still remains the most preferred weight loss supplement. However, we neither endorse nor encourage people to use it because the advantages always outweigh the disadvantages.

We do recommend the legal version of Clen because it’s safe, legal and readily available on the market. What is more, Legal Clenbuterol is capable of recreating similar effects to those of Clenbuterol (or even better).
