What is Clenbuterol?

Clenbuterol is not a steroid per se, but it is similar in properties to anabolic steroids. It can increase muscle mass and thus livestock farmers use it to increase lean muscle in animals for greater profits, which was the primary reason for its development. It fuels protein production that leads to an increase via beta-2 in muscle mass. Clenbuterol acts as a bronchodilator by widening airways for better airflow. Additionally, it also increases blood pressure and heart rate, along with pumping more blood to muscles.

Clenbuterol does not have the approval of the FDA as it is not fit for human consumption, but bodybuilders still use it because of its rapid results. It can be quite dangerous with both short and long term side effects. Moreover, there haven’t been many clinical studies on it due to the number of risks involved. Although, it was tested on animals, especially horses for respiration and mice for experimentation clenbuterol uk

Does it Work?

The majority of the users feel it did help them burn quite a few calories, increase energy levels and enhance muscle growth but at the expense of serious side effects. It takes almost more than 2 weeks to build a tolerance for its effects and people tend to use it repeatedly in cycles. The number of side effects reported is diverse and abundant, some of which transpire within the next 30 minutes of consumption. For instance, people have reported feeling hot-headed, increased body temperature, and increase anxiety that leads to an increase in motivation when working out or training.

Benefits of Clenbuterol UK

Clenbuterol Benefits

 Fat Burning

Clenbuterol is a quicker fat burner as compared to other drugs such as ephedrine. It induces the thermogenic effect that leads to a faster metabolism.  Thus, increased metabolic energy causes more fat and carbohydrates to burn, also leading to a rise in body temperature. Thus, this is one of the reasons why athletes resort to Clenbuterol, because of its fat loss abilities.

 Improves Breathing 

It widens airflows and blood vessels, which helps patients of asthma and other respiratory diseases to breathe easily. The intake of oxygen increases in the blood and is why asthma patients prefer using it. It is also more effective than salbutamol.

Healing and Muscle Growth

People use Clenbuterol after major surgeries as it supports recovery and healing of damaged muscles. Muscle loss also minimizes because of increased protein production and reduced breakdown of muscle fibres. This is also one of the reasons why the meat industry uses it on animals.

Clenbuterol also helps people with muscle degrading conditions as per studies conducted.  One was on 16 patients who suffered from muscular atrophy and another study conducted on 4 patients who suffered from muscular dystrophy. Both studies showed Clenbuterol improved their conditions.

Clenbuterol as a Stimulant

It works as a stimulant because it is similar in properties to adrenaline, which is also why it is a performance enhancer. It increases energy, attention, and focus, which makes working out and sports more motivating.

Improves Urinary Urgency

In a small study conducted on women, Clenbuterol showed improved urinary systems only in 6 weeks. This is on the basis of a small study that is incomplete because of the potential consequences the drug could pose.

Reduced Labor Complications in Animals

In cattle, Clenbuterol decreases labor complications, but the side effects can still backfire. Moreover, it was never tested on humans because of the great risks it can cause.

Clenbuterol Cycle

Bodybuilders and athletes often use Clenbuterol in on and off cycles, for instance, they could take it on 2 consecutive days and then 2 without it. It does not have a fixed dosage as it can vary depending on tolerance, gender, etc. You can take it orally or inject it. Injections are harmful as they can lead to scarring or air bubbles in the bloodstream. The tablets are also harmful as they can adversely affect the liver. The recommended dose for asthma patients, however, is 0.02 to 0.04 mg every day.

Side Effects of Clenbuterol

headacheClenbuterol has a lot of known side effects that are both short and long term. You must know the risks before you decide to start using them. Athletes often abuse the use of Clenbuterol which leads to serious side effects that cannot be reverted.

Short Term

The short term side effects are similar to side effects off coffee or amphetamines. First-timers especially can experience a faster heart rate and blood pressure, along with headaches. Other side effects include dry mouth, difficulty breathing, sweating, muscle cramps, tremors, insomnia, vomiting, dizziness, and nausea. Moreover, headaches, cramps, and nausea are amongst the more common side effects, especially after a workout session.

Long Term

Long term side effects can turn out to be fatal, therefore one must be aware of them before starting to use the drug.

  • Addiction
    The first long term consequence of Clenbuterol is the risk of addiction as it acts like dopamine, which can be highly addictive.
  • Heart Attack
    Since Clenbuterol increases heart rate, these can also turn into palpitations and chest pain. It can increase the chance of heart attack for those who already have heart conditions.
  • Muscle Deformities
    Studies in mice have shown signs of muscle deformities and exhaustion. However, this has not been proved in humans.
  • Food Poisoning
    In China and Spain, people were poisoned because they ate meat or pork that contained Clenbuterol, which is also why it is illegal in most countries to give to the animals.

Who is it for?

Clenbuterol UK is a common choice of drug for athletes especially women because unlike other drugs it does not cause androgenic side effects such as deep voice, thicker or greater facial hair growth typically caused by steroids. Other than that, it targets people who want to lose weight fast or have leaner muscle mass such as bodybuilders. Moreover, people who have respiratory problems such as asthma also use it.

Clenbuterol Law –  Legal to Buy in the UK?

Clenbuterol is legal in the UK as long as it is for private use. It is a Class C drug in the UK, which means it is not sold to the public. Only doctors can prescribe it to treat very severe cases of asthma. However, if you are caught purchasing a huge supply, for distribution purposes then you get punished for possession. The only approvement it has is for the treatment of horses who suffer from respiratory conditions, thus an athlete taking Clenbuterol is forbidden as it gives them an unfair advantage over others.

The Legal Alternative From Crazy BulkClenbuterol UK

It can result in permanent damage to the heart and the liver if you choose to take it orally. In addition, it can also be fatal in certain extreme cases, so using it should not without the consultation of a doctor. Moreover, it can react negatively if you are taking other drugs so one should proceed with caution when starting its use.
