Clenbuterol, also known as Clen, is commonly used for burning fat by those who have experience with competitive bodybuilding.
These users have a basic grasp on the side effects of this drug and its uses.
Despite this, there has recently been an uptick in the amount of questions concerning Clen for bodybuilders that are arriving from those who don’t know much about how it can be used when dieting to lose fat.
These users have often just heard from others at the gym to take a few Clen tablets so that they can “get ripped.”
More frequently, women are coming into pharmacies seeking Anavar and Clen to help with losing fat.
This article will supply information about Clenbuterol, as well as its side effects and uses, so that you can make educated decisions.
We will explain how Clenbuterol can help with bodybuilding and gaining lean muscle mass at the gym while also cutting fat to enhance your physique.
What Does Clenbuterol Do For Bodybuilders?
Clenbuterol is in the class of drugs known as sympathomimetics due to their ability to stimulate the sympathetic nervous system.
It works to ensure a fight or flight reaction, causing a generally stimulant effect.
Clenbuterol is able to achieve this through the activation of beta-2 adrenergic receptors. When these beta-2 adrenergic receptors are stimulated, it causes effects such as:
Bronchodilation, the relaxing of the smooth bronchi muscles. Clen is mainly used in the treatment of asthma because of this effect.
The breakdown of fat within adipose tissue to support weight loss and cutting cycles.
Using a Clen cycle helps with breaking down triglycerides into fatty acids for oxidation, making it an effective cutting substance for competitive bodybuilders.
Dilating the arteries that feed skeletal muscles so that the bloodstream can transport more oxygen to them.
Stimulating muscle anabolism. How this effect is relevant to athletes who want to put on muscle will be explained later.
Once it has been taken, Clen is absorbed well (70 to 80 percent) and stays in the bloodstream for 25 to 39 hours.
Since it has a long half-life, side effects can last for a longer period of time.
Clenbuterol Benefits for Bodybuilding
1. Stimulant and Thermogenic Properties
Bodybuilders often take 60 to 120 mcg of Clen each day with additional compounds used to burn fat such as Yohimbine, T3 (which boosts thyroid function), or an ECA (Ephedrine/Caffeine/Aspirin) stack.
They tend to split the dosage up into many 20 mcg doses throughout the day.
When using Clen for the first time people must first see how sensitive they are to this compound to find out what dosage is right for them.
Clenbuterol acts fast and produces results almost immediately. It is known for its thermogenic effect of increasing body temperature.
When preparing for competitions, bodybuilders often use a Clen stack in combination with steroids such as Equipoise, Anavar and Winstrol.
Those who use Clen report increased muscle strength, particularly during the first few weeks of using the drug. This may be due to its stimulant properties.
2. Down-regulation of Receptors
Since beta-receptors down-regulate quickly, the body adapts to Clen within a short period of time which is why cycling with something else will help you get better results.
This means that there is a decrease in the amount of receptors because of the excess amounts of the beta-agonist Clenbuterol, a normal body response.
This is the reason that it is normally taken over short time periods, commonly of four to six weeks, as well as the reason why users stack it with substances such as Ketotifen so that the receptors continue to work.
As the body adapts to the increase in Clen, the beta-agonist, there will be a decrease in the amount of beta-receptors as it seeks to maintain homeostasis.
3. Anabolic properties
I want to explain this topic thoroughly since many amateur bodybuilders have come to me inquiring about Clen’s anabolic effects.
They have read about this substance and are seeking to avoid the pain of injecting steroids, as well as the side effects.
When Clen stimulates the beta-2 receptors it causes an activation of the anabolic pathways contained within the skeletal muscles, resulting in an anabolic effect.
This results in a small anabolic effect in addition to its weight loss properties.
Though you might be excited about a compound that will help you add muscle while losing fat, be aware that this effect, while having been scientifically demonstrated, doesn’t necessarily happen at the dosages necessary for human use.
Let’s understand the reasons:
Clen’s anabolic effect was shown in animal studies, not human studies, since the research used dosages that aren’t safe in humans, and unnecessary for bronchodilation.
A 1992 study by Choo and associates found that rats who were injected with 4 mg of Clen for each kg of their bodyweight experienced this effect.
This would translate out to 400 mg for a person weighing 100 kg. The dosages used for fat burning are 60 – 120 mcg daily.
Be aware that applying animal data to humans is not safe, particularly when using drugs unsupervised.
There are those who say that they experience excellent muscle retention while taking Clen for bodybuilding, but they also used anabolic steroids such as Equipoise and Winstrol, so the effects of Clen anabolicly can’t be measured.
In some reviews, taking forskolin can also boost results.
These two excellent articles about increasing muscle mass with Clen both agree that the data learned from animal studies doesn’t apply to human usage.
More research is needed to determine cardiovascular side effects, efficacy and safety.
Clenbuterol Legal Status
Though Clenbuterol is legal in the United States and is not considered a controlled substance or require a prescription to buy, it has not been officially approved for human use.
This means that under FDA regulations, it cannot be included in dietary supplements but must be sold as a research chemical. Clen may not even be used for medical reasons in humans in the US.
The only approved use according to the FDA is for racing horses who have breathing problems.
In other countries Clen may be prescribed to treat asthma and other breathing disorders in humans.
In places such as China and Mexico, Clen is given to animals to increase the quality of meat by increasing muscle mass.
As such, if you want to buy Clenbuterol for bodybuilding purposes, you will have to seek out wholesale chemical suppliers who cannot label their product for human consumption.
Clen may be found in 0.01 or 0.02 mg tablets, or as a Clenbuterol Hydrochloride syrup. Remember that this chemical is listed as a banned substance by the WADA and natural bodybuilding federation.
Clenbeuterol is on the World Anti-doping Agency’s (WADA) list of drugs that enhance performance.
Many federations that promote natural bodybuilding such as the INBA (International Natural Bodybuilding Association) include beta-2 agonists such as salbutamol and Clenbuterol on their list of banned substances since they follow the protocols of the WADA.
Do not take this drug if you are planning to compete in any of these associations as you will be disqualified from competition.
Clenbuterol has been shown to produce exceptional fat burning results, but it can sometimes cause major side effects.
Since Clen stimulates the nervous system it does sometimes produce emotional side effects including anxiety, paranoia and extreme nervousness.
Tremors often occur as well which can make daily activities such as typing writing and holding things difficult. Particularly with high doses insomnia may occur.
Those who have psychological problems such as anxiety and depression have a higher risk of experiencing these side effects when taking Clen for bodybuilding.
If you have these disorders, taking to a medical professional prior to Clen use is advised.
It can also lead to long and short term cardiovascular effects.
These side effects come on very quickly and include an increase in blood pressure as well as heart palipations (tachycardia), and the headaches that often go along with these.
For some people, this causes them to stop Clen usage. In rat studies, using Clenbuterol over the long-term resulted in collagen fibers being infiltrated into the wall of the heart.
These cause the heart muscle to stiffen and lose function.
Since most people use this drug without the supervision of a doctor, these cardiovascular side effects should be taken seriously, since they could easily bring on a tragedy.
Clenbuterol use has been responsible for the sudden death of users.
Finally, Clenbuterol does sometimes result in severe cramping since it uses up the body’s supplies of taurine, an amino acid.
This can be prevented by supplementing with taurine while taking Clen. Bodybuilders would be wise to use taurine and potassium supplements in a stack with this compound.
You should also avoid taking it before a workout as it may cause your heart to race or your muscles to be fatigued more rapidly.
The best time to take it would be several hours before a workout or an hour after.
While Clenbuterol can have positive effects for muscle building in athletes, there are side effects that need to be managed properly.
