Clenbuterol is a type of drug called a sympathomimetic, compounds that mimic the way that adrenaline (epinephrine) and noradrenaline (norepinephrine) work in the body.
It is used medically as a bronchodilator and decongestant, normally in people who have asthma.
It is also increasing in popularity for use as a weight loss aid. Bodybuilders frequently take it in a cutting cycle to improve muscle definition.
There are celebrities who have been suspected of making use of Clenbuterol to slim down, one of whom was Britney Spears.
Many famous athletes were also suspected of making use of it, including MLB plaers David Segui and Jason Grimsley, and the tennis player Mariano Puerta from Argentina was punished for using Clenbuterol.
Clen also works for athletes as a performance enhancing drug, which is why it has been banned in many sports organizations to prevent individuals from having an unfair advantage.
Professional athletes and bodybuilders find the thermogenic properties of Clenbuterol very beneficial. Thermogenics cause a rise in the temperature of the body.
Also, Clenbuterol increases the body’s ability to metabolize glycogen, because it releases glycogen, as glucose, into the bloodstream and makes the body unable to use or store the glycogen.
Because of this, protein and fat are use more quickly by the body for a trio of important reasons: producing energy, recycling the components of molecules, and excreting these components.
This enables those using Clenbuterol to lose body fat.
Clenbuterol is very useful to athletes and bodybuilders since it revs up the aerobic capacity of the body.
To put it more simply, it helps the body transport oxygen by increasing blood pressure.
Because of this, Clenbuterol is a major element in the drug protocol of many endurance athletes.
People use Clenbuterol for anabolic reasons, though this is controversial. Some animal research studies have shown noticeable gains in muscle, though this hasn’t ever been seen in humans.
Clenbuterol is, however, often given to livestock, leading to animals that are leaner and more muscular.
It is recommended that doses should be increased over time so that individuals can see what their level of tolerance is.
This is achieved by slowly increasing the dosage every day till the best and most comfortable dosage range is decided.
When approached in this way, many of the harmful side effects of Clen are avoidable, particularly the effect it can have on blood pressure.
The typical dosage for females is 2 to 4 tablets each day, and for males it is 2 to 8 tablets each day.
The user’s goal will determine how long of a cycle Clenbuterol should be taken in.
If fat loss is the goal, a cycle of 4 to 6 weeks is best, and keeping a watch out for the decrease or increase of body temperature is important.
Since it is a thermogenic, it works mostly by rising the temperature of the body, so when used over a long period of time, when the body temperature drops, it isn’t working as well.
This is a sign that you should go off of Clenbuterol for a few weeks or longer.
Taking more of the drug, or taking it longer will not be effective, and be a waste of your money because your body grows resistant to it after a time.
You must cease use for a time so that the body can readjust.
In order to maximize the ability of Clenbuterol to burn fat, some take other drugs with it, like T3, a thyroid hormone Cytomel.
This popular combo is often used when preparing for a contest of while on a cutting cycle, to help bodybuilders remove excess body fat while continuing to eat enough protein.
It is also normal to stack Clenbuterol with anabolic steroids that are non-aromatizing, that is those that don’t cause you to retain water. This stacking allows the drugs to work synergistically.
Clenbuterol is used by bodybuilders who want the lean, ripped, striated look, because of the catabolic activity where fat is concerned.
This catabolic function can work against you though, because it may also work on muscles, so muscle gains may be lost.
Because of this, it is commonly used with anabolic steroids so that lean muscle isn’t lost.
Side effects that have been seen with Clenbuterol include nausea, an increase in blood pressure, muscle spasms, insomnia, increased sweating, headaches, tremor, palpitations and restlessness.
It shouldn’t be used by who have been diagnosed with cardiovascular issues. Using Clenbuterol for long periods of time may cause the heart to enlarge.
However, it is important to remember that Clenbuerol, while not a steroid, is nevertheless not allowed by many sports associations.
Clenbuterol definitely works, but you have to use it in the right way to make sure that it does not cause you problems in the long run.
