Facts About Clenbuterol That No One Will Dare Tell You About!

When you ask this simple question, ‘what is Clenbuterol,’ you will be overly surprised by the answers you receive.

Someone will tell you that Clen is an asthma medication for horses and humans; another person will answer and say that it is a performance-enhancing drug and fat burner.

It seems confusing, right?

By the time you reach the end of this clenbuterol article, you will have a clear understanding of just what clenbuterol is used for, how it works and how life-threatening it could be if you take and misuse it.

Everyone knows that shedding that extra body fat is a challenging task.

Here are the facts.

If you want to get that ripped look, you need to rev up that metabolism! Every gym enthusiast is always looking for that perfect pre-workout supplement. 

Furthermore, it is the choice fat loss drug that bodybuilders, athletes, and the Hollywood crowd love.

What Is Clenbuterol?

Clenbuterol is a potent fat-burning compound with significant muscle preservation and some muscle-building effects.

Hang around a gym long enough, and you might come across names like Dilaterol, Ventipulmin, or Spiropent in your search for the perfect fat loss drug. However, “Clen” or “Bute” all mean the same.

It is also a stimulant related to Ephedrine. It belongs to a class of drugs called beta-2 agonists.

What does this mean for you?

Bute will increase your metabolic rate by burning your body fat instead of your muscle.  It will build some muscle and helps you gain your strength back after an injury.

Another surprising fact is that Clen is NOT considered a steroid, although it does have a steroid-like chemical structure.

Without getting in too thick, synthetic steroids are just copycats of the hormone testosterone. Bute is indeed not that.

It is a sympathomimetic amine. Meaning, Clen acts as a stimulant on the nervous system.

It binds to the same receptors as epinephrine (adrenaline). Only clenbuterol does it better, and that gives it the ability to burn fat.

Studies on humans and animals have clearly shown that clenbuterol will raise the metabolic rate and stimulate fat burning. 

However, in most countries, Clenbuterol for sale is banned. Furthermore, it is illegal to feed it to animals that humans will consume.

Why Was Clenbuterol Used As An Asthma Treatment?

Clenbuterol was first established in the 1970s as a veterinary drug to treat respiratory conditions in horses and other animals.

It has the unique ability to act as a bronchodilator by relaxing the muscles around your airways, making it easier to breathe.

It is used as a nasal decongestant and asthma medication for humans in some countries. However, the United States disapproved of it.


Beyond the weight loss and pre-workout attraction of this drug, Clenbuterol has some pretty wicked side effects.

Who’s right, then?
You should seriously take heed of the warnings!

How Clenbuterol Should You Take?

Bodybuilders and fitness buffs usually cycle a clenbuterol dosage between 20 and 40 mcg. A beginner cycle of clen should keep the dosage between 10 and 20 mcg.

A cycle usually consists of two days on and two days off or perhaps one week on and one week off. 

The dosage of clenbuterol usually depends on tolerance and gender.  Plus, whether or not it is injected or taken orally.

Both methods involve specific risks. Injections can cause air bubbles to be formed in the blood, while oral tablets can affect the liver.

Clenbuterol effects are shown on an athletic man and woman

1. Supercharges your airways

It supercharges your airways so your lungs can fill up with more oxygen-enriched red-blood cells, which enhance aerobic activity.

Furthermore, it keeps the lungs clear of any mucus that could interfere during a strenuous workout by opening up the airways.

What does this mean for you?

This oxygen-enriched blood can now reach all of your muscles. Thus biking, jogging, bodybuilding, tennis, and more will improve tremendously by giving you greater endurance and stamina.

2. Clenbuterol fat burner properties

Imagine the core temperature of your body rising by just 1 degree F? Clenbuterol creates a thermogenic effect on the body and could lead up to a 5% increase in calories burned!


It jacks up your metabolism so your body can use that additional energy to burn fat instead of muscle.

3. Clenbuterol lean muscle building

Muscle hypertrophy /hīˈpərtrəfē/ is just a term for muscle growth.  Although Clenbuterol has anabolic properties similar to steroids, you won’t get bulked up using it.

Moreover, using Bute will give your body a more defined and hard look. It stimulates muscle protein synthesis, which builds muscle and repairs it especially, after injury.

Resistance training injures the muscle you are working on. Bute maximizes our recovery time by quickly repairing those same muscles.

4. Clenbuterol raises your BMR

At best, Clen can raise your basal metabolic rate about 10%, which does help without a doubt, but you could probably treadmill for 1/2 hour or walk an hour to get the same effect.

What are the Clenbuterol side-effects?

Throughout this what is Clenbuterol article, we warned you about the dangerous side-effects.  Now we are going to list them all below.

Why is Clenbuterol not good for your heart?

First, since it acts like an amphetamine, it can cause your blood pressure to rise and keep it that way for long periods.

As a result, it can increase your risk of LVH or left ventricular hypertrophy; this is a thickening of the walls in the left side of your heart where all the pumping of blood to your organs occurs.

Second, there is some evidence that Bute can kill heart cells, making it a significant player in the battle over heart disease.

How can Clenbuterol mess up your sleep?

If you take it too late in the day, you will probably be up all night.  As I stated before, Clenbuterol is a powerful stimulant, and that’s a fact.

Furthermore, besides spiking your metabolic rate, its half-life or time stays in your system is a lot longer than less severe drugs like caffeine or ephedrine.

Moreover, it can stay in your system for 24 to 48 hours, and this, my friends, can cause some frightening sleep privation.
