What is Clenbuterol?
Clenbuterol, which is commonly referred to as “Clen”, is a bronchodilator which is available on prescription in some countries to treat conditions such as asthma. It is commonly used by athletes and bodybuilders because of its fat-burning and anti-catabolic effects.
It is thought to enhance aerobic capacity, stimulate the sympathomimetic central nervous system and increase blood pressure and the transportation of oxygen around the body, as well as increasing the rate at which fat is metabolised.
Clenbuterol for sale online is typically seen under the brand names Astralean, Clen, Dilaterol, Spiropen and Ventipulmin. It is a ß2 agonist that is structurally similar to epinephrine and salbutamol, though its effects are longer lasting.

Clenbuterol was widely used to treat patients with asthma, and, until relatively recently, was the active ingredient in most asthma inhalers prescribed in North America. It is still used in Bulgaria and China. Clen can also be used to treat hypertension, migraines and allergic reactions, including anaphylactic shock.
- Encourages weight loss
- Prevents break down of muscle mass
- Less side effects than some other steroids
- Targets abdominal and visceral fat
- Increases aerobic stamina
As well as finding favour with athletes and bodybuilders, who are keen to build up muscle mass, Clenbuterol steroids are also popular with those who are seeking to lose weight. Notable celebrities reported to have used the drug include Britney Spears and Victoria Beckham.
How does Clen work?
As a ‘thermogenic’ it works by increasing body temperature, which in turn stimulates the metabolism and helps to burn more calories. A 1% rise in temperature is thought to produce a 5% increase in calorie burn.
The ‘Anti-catabolic’ side of this drug control the release of amino acids to the muscles, which prevents the breakdown of muscle mass. Studies on livestock have demonstrated that Clenbuterol has anabolic (muscle-building) properties.
This drug also helps to metabolise glycogen, which is released as glucose, into the bloodstream. This increases the rate at which protein and fat are used and excreted, which is why a Clenbuterol cycle is thought to be beneficial in terms of fat reduction and weight loss.
It can increase the aerobic capacity by helping to transport oxygen and increasing the blood pressure. Its anabolic properties are not proven in humans, though animal research has demonstrated that Clenbuterol produces more muscular and leaner animals.
It’s popularity also lies in the fact that it can be taken just once a day, and has an active half-life of 24-36 hours. After this time, its strength dilutes by half every 24-36 hours. However, the cumulative effect of this drug can make overdosing a very real danger.
Typical dosage and Clenbuterol cycles
Many users recommend tapering the Clenbuterol dosage upwards on first usage in order to limit the side effects, starting with just 20mcg tablet on day one.
Increase the dose by 20mcg each day until the maximum 140mcg is reached on Day 7. 140mcg should then be maintained throughout the second week.
On starting the second cycle, at week 5, there should be no need for tapering up from just 20mcg, though some people recommend starting the second Clenbuterol cycle below the maximum (perhaps 80-100mcg) and building up again over several days.
Many athletes add a potassium supplement (200-400mg per day) or ensure they eat plenty of bananas to counter the potassium depleting effects of Clenbuterol. Female athletes are advised not to exceed 120mcg per day.
After each two week Clenbuterol cycle, there should be a two week period without taking the tablets. Some bodybuilders use an ECA stack during ‘off’ weeks, though Clenbuterol/ECA must be limited to a maximum of 12 weeks.
Potential Clenbuterol Side Effects
Clenbuterol side effects are, in the main, dose-dependent and recommended dosages should not be exceeded.
Nausea, headache, vomiting, diaphoresis, palpitations, tachycardia and myocardial infarction have all been reported, though most users suggest that side effects diminish over time.
Clenbuterol should not be taken with other adrenoceptor agonists, or side effects are likely to be intense.
For that reason, caution should be exercised before using ephedrine/ephedra or the ECA stack whilst taking this drug.
A fairly common Clenbuterol side effect is cramping, which is probably caused by a reduction of taurine in the liver, coupled with dehydration. Rat studies suggest that a taurine supplement may help if cramp becomes a real problem, or alternatively a potassium supplement, though sensible nutrition (bananas are particularly effective) and plenty of liquids will be sufficient for most people.
Warning: Those with cardiac problems or hypertension should avoid taking Clenbuterol.
What are the laws surrounding its sale?
Clenbuterol is approved in the US only to treat animals suffering from asthma-type symptoms and it has not attained FDA approval for human use.
Although it is not included within the Controlled Substances Act, Clenbuterol is banned by the World Anti-Doping Agency and the International Olympic Committee as it is regarded as a performance enhancing drug – as with most steroids.
It seems that in terms of legality, it is lawful to possess Clenbuterol for personal use, though clearly competing athletes should avoid it.
A number of high profile athletes have received long bans since 1992 onwards, most notably Guillermo Mota, pitcher for the San Francisco Giants, who has served two bans, and swimmer, Jessica Hardy as well as a whole host of cyclists and footballers.
Whilst some sports persons who have tested positive for Clenbuterol have successfully argued that their positive results were caused by contaminated meat (some farmers feed Clenbuterol to animals in an attempt to produce lean meat), the World Anti-Doping Agency is funding research to find a test that will identify the origins of the drug and eradicate this partial defence once and for all.
Is there a way around this? – Clenbuterol For Sale Legally in the US
