It’s a Latin American version of Clenbuterol, or more specifically a Clenbuterol derivative known as Clenbuterol hydrochloride.
It’s mainly manufactured in Venezuela and can be found for sale from a number of steroid shops around the world.
While Clenbunal is not an anabolic androgenic steroid, it does have some of the similar properties of bodybuilding steroids, though to a much lesser degree.
Unless you speak Spanish, it can be difficult to find in-depth information about Clenbunal.
This is because most of the searches of the drug form come from Latin American countries where website content is in Spanish.
Nevertheless, as a derivative of Clenbuterol, it will provide the same mechanism of action, as well as recommended dosages – for medical purposes.
Clenbuterol is no longer approved for medical treatments in the US on humans, and in many countries around the world, its use is limited to veterinary practice.
It should be noted that Clenbunal is not found nor approved as an ingredient in any bronchodilator products or other drugs that have been approved by the US Food and Drug Administration.
How Does Clenbunal Work?
Clenbunal, or Clenbuterol hydrochloride, belongs to a class of sympathomimetic amines that are most commonly found in bronchodilator medications in inhaler form for the treatment of asthma or severe and chronic lung conditions that might also include emphysema.
The mechanism of action of Clenbuterol (Clenbuterol hydrochloride) is to dilate the smooth tissues that line the bronchial tubes in the lungs.
It’s classified as an adrenergic beta agonist, and as such, specifically targets, attaches to, and activates beta-adrenergic receptors in the body.
As a sympathomimetic amine, Clenbunal affects the sympathetic nervous system, which include functions over which we have no control.
One of those is respiration. During an asthma attack, the bronchial tubes in the lungs constrict, causing narrowing. This limits intake of oxygen.
Clenbunal and other brand name forms of Clenbuterol reverse this effect, widening or dilating the air tubes, increasing oxygen intake.
For someone with a medical condition that affects lung function, these benefits can be lifesaving.
When used by a bodybuilder or athlete who already has adequate lung function, benefits can often be outweighed by side effects.
Why would a bodybuilder use Clenbuterol? Because of its mechanism of action.
It has the ability to increase oxygenation. Oxygen is essential for cellular growth. In addition, oxygen also carries a number of vital nutrients to all cells of the body, including muscle that enhance optimal health and wellness.
Another reason is due to some fat burning potential, though this role is minimal in regard to thermogenesis or energy production/fat-burning capabilities.
Bodybuilders considering use of Clenbunal for this purpose should be aware that it is minimally effective, and typically only on those with an already lean body mass.
Average Weight Loss
Weight loss in such cases might range three to five pounds for most, and is not considered effective at all on someone who is overweight or obese.
It also has a reputation for accelerating muscle growth, though again not to any great degree.
This is due to the delivery of oxygen and other nutrients into the muscles, combined with the energy production previously mentioned.
Used alone, it will not produce significant or even moderate muscle mass gains.
A bodybuilder would have to take excessively high dosages to achieve even minimal benefits in this regard.
Some studies have determined the Clenbuterol used in cattle can improve development of lean muscle mass, and it can prove somewhat effective in weight loss, as well as protein synthesis which in turn stimulates tissue and muscle growth.
Even so, the effects are temporary and only in unique circumstances. In humans, some may experience benefits in regard to muscle development, but results differ.
Clenbunal Side Effects
While bodybuilders tend to shrug off potential side effects with use of different types of drugs for nonmedical reasons, adverse reactions associated with misuse of Clenbuterol hydrochloride are not to be ignored.
When it comes to weight loss, diet and exercise is a safer and more natural way to maintain long-term weight loss and trim body form, even for athletes and bodybuilders.
Other studies have determined a number of adverse effects in bodybuilders misusing and abusing different forms of Clenbuterol.
Potential liver toxicity is another concern with misuse of different forms of Clenbuterol.
Other side effects are certainly possible, and of greatest concern is disrupting metabolic functions in the body.
Putting any substance into the body that it doesn’t need can disrupt and interfere with hormonal and metabolic processes.
Some Clenbuterol reviews left by former users have claimed that it worked for a few days and then stopped working. Others complained of disruptive eating disorders.
Others claimed that after losing weight and discontinuing Clenbuterol, the weight quickly returned.
Overall, Clenbunal tablets as a bronchodilator are effective in medical treatments, but as a weight loss/muscle building component to a bodybuilders routine – not so much.
