What Is Clenbuterol? Cycle, Dosage, And Side Effects

When people think of anabolic steroids.

They think of huge increases in strength, size, and muscle mass.

While there are plenty of steroids out there that do indeed allow people to make those changes to their physiques.

There are also steroids that act very differently.

That’s why today, we’re going to be looking at what is Clenbuterol?

We all know how difficult it is to burn fat and lose weight.

But did you know that certain steroids out there can potentially help you to get ripped and shredded such as Helmut Strebl?

Clen is one of those steroids, which is why we are going to focus on it today.

Remember, losing body fat is a hard process at the best of times.

Especially when you have less to lose.

For bodybuilders struggling with those last few stubborn pounds.

Those last few pounds could be the difference between a 1st place finish, or the last place finish.

You obviously want to look as ripped and as shredded as possible.

Which is why Clenbuterol could be the perfect steroid for you.

Clen is very effective, it’s easy to come by.

And if you follow our guide on what is Clenbuterol, it’s easy to use.

Below we are going to look at what the drug is, what it does, side effects, cycle info, dosage info, PCT and much more besides.

So, if you’re ready, pull up a chair, get comfortable.

And let’s find out more about Clenbuterol.


What is Clenbuterol?

Clenbuterol is one of the most popular fat-burning compounds available on the underground market.

It is a beta-2 agonist that is very similar in structure and effectiveness to other stimulating drugs on the market, including ephedrine.

Which is itself now a banned substance!

Not surprisingly, this drug wasn’t created primarily for physique-enhancing purposes.

It was created for medicinal purposes and was designed to be a drug used by veterinarians.

It was created to function as a bronchodilator to help clear the airways.

It was even prescribed to asthmatic people to help them breathe easier.

Clen is currently available in a number of different forms.

It is found in capsule form, it can be injected.

It is found in inhalers.

And there are even Clenbuterol syrups that you swallow just as you would cough medicine.

Its active life is approx 68 hours.

Whereas the half-life is around 36 hours.

When it comes to contesting prep or cutting in general.

Clen and winstrol are the two steroids of choice for bodybuilders.

It strips fat away like never before while helping to preserve muscle mass.

In theory, it’s not a steroid, exactly like Cardarine.

But for today’s purposes.

We’ll refer to it as such to try not to over-complicate things.

Not only does Clen help to burn body fat.

But it also preserves lean muscle tissue.

Many people don’t realize that Clen also serves as a powerful decongestant.

Which means that it serves as a blood-thinner and helps to thin the blood.

When you combine this with the fact that it also widens the blood vessels as it serves as a bronchodilator.

You can see how this can assist with athletic performance.

While it was initially designed to treat asthma in horses.

It was eventually found that it acted like a powerful stimulant that helped to shred body fat.

It increases core body temperature and stimulates the central nervous system as well as the heart.

It is also a beta-2 agonist, as we mentioned.

Which means that it is the exact polar opposite of a beta-blocker.

Which slows everything down.

Clenbuterol For Weight Loss

As you can probably tell by now.

Clenbuterol is a compound that is utilized primarily by people looking to lose weight and burn fat.

But how exactly, does Clenbuterol assist with fat loss?

Well, we’ll do our best to explain to you right now.

You see, Clen is a beta-2 adrenergic receptor and so it mimics the effects of adrenaline in the body.

This, in turn, results in the production of a compound known as CAMP which is a form of ATP that helps increase energy levels.

In turn, an enzyme known as protein kinase is also increased.

Which helps to regulate fat and glucose metabolism and so your body becomes more efficient at burning fat and converting it into energy.

So, Clen helps you to burn body fat and use it for energy to get you through your workouts.

This means that it is literally a win-win situation for anybody trying to lose fat and improve their performance in the gym.

What Does Clenbuterol Do?

So, now that we’ve looked at what is Clenbuterol.

It’s now time for us to take a look at some of the main effects of Clenbuterol on the body.

When using Clen.

It’s important to know not only what it is.

But also what it does, and how it works.

Here’s a look at some of the main effects of Clenbuterol use that users can benefit from.

Fat loss

First and foremost, Clenbuterol is primarily used as a fat burner in bodybuilding circles.

Clenbuterol helps to stimulate the heart and central nervous system.

Which in turn increases the core body temperature.

It is very thermogenic and as the body’s core body temperature rises.

The body struggles to regulate it.

To compensate for this.

It has to work harder to keep the temperature at a constant.

Which means that it needs more energy.

It gets this energy from calories stored in body fat.

And the more calories the metabolism burns, the more fat you use.

As an analogy, think of a fire as your core temperature.

And a big pile of logs as your calories.

Normally when the fire burns steadily.

You will throw one or two logs on every few hours to keep it ticking over.

When you introduce Clen, the fire suddenly roars to life and burns like an inferno.

To keep the fire burning this way.

The body panics and utilizes your metabolism to add more fuel to the fire.

Instead of one or two logs every few hours.

You will now be burning three or four logs every single hour.

This means that the log pile.

Which in this instance is your body fat!

Goes down much quicker than normal, so you burn fat much easier.

Performance Enhancement

Another way in which Clen proves useful is that it serves as a performance-enhancing drug.

You see, Clen is a bronchodilator and a decongestant.

Which for athletic purposes is ideal.

A decongestant helps to thin the blood, whereas a bronchodilator causes blood vessels to widen and expand.

This is perfect because it means that more blood can be carried around the body.

What does this have to do with athletic performance?

Well, our muscle cells get their energy from oxygen and nutrients.

Which are transported to them via red blood cells in the blood.

By thinning the blood, you can carry more blood around the body, which means more oxygen.

On top of that, as the blood vessels have now widened.

This means that yet more blood can be carried around the body.

Which again means more oxygen and more nutrients for the cells.

The cells soak all of this up and the muscles have more energy than they know what to do with.

This leads to greater muscle contractions and longer bursts of energy before muscle fatigue.

More Physical And Mental Energy

When it comes to training, it is not only important to have physical energy, it’s also important to have mental energy as well.

Where the mind goes, the body will follow.

But if you aren’t mentally psyched to workout, your workouts are going to suck!

Clenbuterol is a stimulant that stimulates the heart and the central nervous system.

It functions like ephedrine and amphetamine for that matter.

Which are two incredibly powerful stimulants?

This means that when you consume Clen.

You have more energy than if you had downed a powerful pre-workout powder with a double shot of espresso for good measure.

You will have the energy of 10 men and your brain will be in the game as well, so you can get your head right.

Clenbuterol side-effects

We’ve looked at the good, and now it’s time to look at the bad.

Clenbuterol is a drug that must be respected and used as instructed, and even then, there are still certain risks associated with it.

Here’s a look at some of the main Clenbuterol side-effects that users should be wary of:

Heart risks

As mentioned, Clenbuterol is a very powerful stimulant, as because of this it does pose very significant risks to a person’s cardiovascular health.

Stimulants increase a person’s heartbeat, which means that the heart is put under more pressure.

Now, if you have a healthy heart, the risk is reduced but is still there.

If you suffer from heart issues, however, it is recommended that you give Clenbuterol a risk as it could potentially result in a heart attack, which could be fatal.


When people drink too much coffee, because of the caffeine, it can cause shaking and anxiety.

Clenbuterol, however, is far more powerful than coffee, so again, it can result in severe shakes and anxiety.

If you already suffer from anxiety, using Clenbuterol is a big risk because it would likely exasperate the condition and make it much worse.


As mentioned, primarily Clen works by raising the body’s core temperature.

This means that its thermogenic action results in your warming up and feeling hot.

This, in turn, can lead to abnormal and sometimes profuse sweating, both during the day and at night.

Night sweats on Clen are very bad, so you may wish to consider sleeping with the A/C cranked way up.

In the winter, you will likely sweat on Clen, but during the summer, you’ll feel hotter than ever.

Headaches And Shaking

Again, because of the stimulating effects of Clen, people are likely to shake and feel jittery when using this drug.

On top of that, however, it is also common to suffer from headaches.

One key reason for this is down to dehydration.

Because you sweat so profusely on Clen, you obviously lose a lot of water and a lot of electrolytes.

This basically means that you suffer from dehydration and a common side-effect of dehydration is a headache.

To compensate for this, make sure you are constantly sipping on water throughout the day when on a Clen cycle.

Clenbuterol cycle

Speaking of Clen cycles, here’s a brief look at a common yet very popular cycle for you to try if you are serious about using this drug.

  • Day 1: 20 mcg
  • Day 2: 40 mcg
  • Day 3: 60 mcg
  • Day 4: 80 mcg
  • Day 5:100 mcg
  • Day 6: 120 mcg
  • Day 7: 120 mcg (break this into two doses of 60 mcg each)
  • Day 8: 120 mcg (take this normally)
  • Day 9: 100 mcg (take this preferably before the evening, i.e. 5 pm at the latest)
  • Day 10: 80 mcg
  • Day 11: 60 mcg
  • Day 12: 40 mcg
  • Day 13: 20 mcg

Take 2 weeks off, and begin the cycle at 80mcg per day, working up to 140mcg per day, and then back down over 2 weeks.

Clenbuterol Dosage

So, just to be clear and to ensure that there is no confusion when it comes to Clen dosages.

It’s important to pyramid up and then pyramid down.

You begin at 20 and work up to 120 mcg after a week, and then back down.

You then take 2 weeks off, and begin at 80 and work up to 140 mcg after a week in 20 mcg increments, and then back down again.

Is Clenbuterol Legal?

The internet is full of self-professed “experts” with seemingly everybody being an expert when it comes to health and fitness.

The problem is that when you ask a question online,.

You can never get just one straight answer.

If you ask people online whether clenbuterol is legal.

Some people will say yes, and some will say no.

So, who do you believe?

Well, you believe the person that’s telling the truth.

In the United Kingdom and the USA, and many other countries worldwide.

Clen is NOT illegal.

This means that it is not a banned substance and that it’s perfectly legal to use it, right?


Oh no, here we go.

Nothing’s ever simple, is it.

In the UK and Canada, you can purchase Clen if it is for personal use.

It is, however, illegal to purchase it in bulk with the intention of selling it on to others.

If you are caught buying it in bulk with the intention of selling it.

You will be prosecuted as a drug dealer and you could face jail time.

In the USA, Clen is not even approved for personal use.

You can buy it, as long as it is for veterinary purposes as it is used to treat breathing issues in horses.

That is all.

It is not legal nor approved for health, fitness, or personal use.

And if caught, you will be fined and you could be prosecuted.

We won’t talk about legality in every country worldwide because we’d be here all day.

Generally, however, Clen is only approved for veterinary purposes.

The FDA has this product listed as a banned substance if used for dietary purposes.

Is PCT required?

When using steroids, it doesn’t matter whether you run something mild like Anavar or something incredibly powerful like Deca Durabolin.

PCT is always required.

PCT stands for post cycle therapy, and it is something that you run once your steroid cycle has ended.

Now, Clen isn’t a steroid, but it can still result in muscle wastage and organ damage if you’re not careful.

And if you’re looking for some steroid alternatives that work.

Clenbutrol can be a good choice for you, for men or for women.

Many therefore say that PCT on a Clen cycle alone isn’t needed.

Although you should still use organ supporting supplements like Milk Thistle and Hawthorn berry extract.

If you are stacking it with steroids, however, then you will need PCT.

Which will likely come from Clomid or Nolvadex!
