Let’s unravel this mystery, shall we?

It is a synthetic stimulant and not a steroid which has a similar mode of action with ephedrine or amphetamines. Clenbuterol intake increases blood pressure, heart rate, metabolism, and breathing. Long term use causes an increase in muscle mass and fat reduction.

It has different trade names such as Dilaterol, Ventolase, Spiropent, and NAB 365.

Who Makes Clenbuterol?

Clenbuterol was patented around 1967, and later in 1977, it was released in the market for medical use.

Initially, it was used to treat horses with breathing problems; it opened up their airways and restored normal breathing. When it was later administered on cattle, people noted that they lost fat, which meant better meat.

When bodybuilders learned the impact of Clenbuterol on cattle, they also started using the product. It became very popular, and the scientist began to do some research on it. They concluded that it’s a Beta-2 agonist, which means it increases adrenaline levels in the body.

Currently, it’s illegal to import the product either for human consumption or for sale. It’s banned in many countries, and it’s not approved by the FDA as safe for human consumption. However, it’s still used by many bodybuilders and people looking for fast weight loss results.

Clenbuterol is also illegally used to boost livestock growth; there are many cases of Clenbuterol contaminated meats that have been reported globally.

One of the most famous pharmaceutical brand names that manufacture Clenbuterol is Sopharma; according to their official website, it’s based in Bulgaria.

There is no legal Clenbuterol brand available in the UK, Australia, and the USA.


  • Burns fat

Clenbuterol reduces fat mass more than the other fat burners; this is called the thermogenic effect, which causes an increase in metabolic energy.

It increases blood pressure and heart rate, which causes a rise in body temperature and increased metabolic activity. This burns a lot of fat and glycogen/ stored carbohydrates.

Most athletes use Clenbuterol to lose fat during cutting cycles.

  • Promotes breathing

Clenbuterol is used to treat asthma since it improves obstructed breathing. It widens and relaxes blood vessels which increases oxygen volume in your blood and supports aerobic respiration

Several countries are still using Clenbuterol as a bronchodilator and decongestant in humans. It is also used to treat horses with breathing problems.

  • Improves muscle degrading condition

In a case study, Clenbuterol was used to treat patients with muscular atrophy; the patients improved their mobility significantly, and the condition was controlled. The product is also great in maintaining muscles that have been rendered dormant as a result of injuries or disease.

Clenbuterol is used to stop muscle degradation in people suffering from dysfunctional nerves where it efficiently reverses muscle degradation triggered by tissue burns.

Clenbuterol can also be used to treat elderly people suffering from muscle wasting and boost muscle mass in patients with chronic diseases like cancer.

  • Used as a stimulant

Clenbuterol is used by athletes to increase energy. It has similar effects as adrenaline as it activates the sympathetic nervous system; thus, it’s used as a performance-enhancing drug in sports.

It’s used as a stimulant to increase attention, alertness, and energy levels. This makes workouts more enjoyable, some users experience improved competitiveness, aggression, and motivation it also suppresses appetite when working out.

  • Builds and repairs muscles

Clenbuterol promotes recovery in surgery patients. It boosts muscle growth by reducing muscle loss and accelerating protein production.

Although Clenbuterol is illegal in many countries, meat industries use it to increase muscle growth in animals.

  • Improve heart function

High doses of Clenbuterol was administered on patients with heart failure for about 5-46 weeks. It helped in restoring heart function by reversing the expected decrease in heart cell size, and the patients had their implantation done successfully.

  • Acts as anti-inflammatory

Clenbuterol protects the liver and brain from inflammation-induced injury. This effect was observed in rats and horses, whereby the activity of white blood cells was reduced by Clenbuterol intake. Cell studies show it inhibits the production of IL-1 beta, IL-6, and TNF-alpha.

  • Lowers labor complications

Clenbuterol has muscle relaxant effects, which have been used in animals to reduce labor complications. It has never been researched in humans because of the risks involved. In cattle, it has been used to correct birth complications without using anesthesia.

  • Antidepressant

Clenbuterol intake increased serotonin and tryptophan levels, just like most ant-depressant drugs. However, this needs more research to evaluate the outcome when using the product as an antidepressant.

Side effects

Clenbuterol use has many long and short term effects, which are dangerous. It’s also very potent, small doses are required to feel the impact.

Short term side effects

  • Insomnia
  • Nausea and vomiting
  • Increased heart rate, blood pressure, and palpitations
  • Dry mouth
  • Restlessness, Anxiety, and nervousness
  • Intense sweating
  • Rapid breathing
  • Muscle spasms and cramps
  • Increase in body temperature

Long term side effects

  • Addiction-Clenbuterol affects dopamine, meaning it can be very addictive
  • Heart attack: Clenbuterol intake increases heart rate, causes palpitations, abnormal heartbeats, and chest pains. This increases heart attack risks, especially in susceptible individuals.
  • Muscle deformities
  • Drug interactions: When Clenbuterol is combined with beta 2 receptor activator drugs, it can cause serious side effects.
  • Many Clenbuterol users take it illegally without consulting doctor, which is risky because a doctor can prescribe to them another drug that doesn’t interact well with Clenbuterol.


Clenbuterol mode of action

Clenbuterol belongs to a class called sympathomimetic amine which activates fight or flight system. It activates beta 2 adrenergic receptors located in bronchiolar smooth muscles, this leads to smooth muscle relaxation. This widens airways and increases airflow, which improves breathing.

It also stimulates CNS and leads to an increase in heart rate and blood pressure due to adrenergic activities of beta 1 and beta 2.

This supplies the muscles with more blood to get ready for physical activity and promotes the burning of fat to release energy.
