Clenbuterol (also known as Clen) is a sympathomimetic amine used by sufferers of breathing disorders as a decongestant and bronchodilator. People with chronic breathing disorders such as asthma use this as a bronchodilator to make breathing easier. It is most commonly available as the hydrochloride salt, Clenbuterol hydrochloride.

Clenbuterol belongs to a class of drugs called beta2-agonists. Drugs in this category can cause dilation of the bronchial muscles. In addition to being used to treat asthma, Clenbuterol has become popular as a weight loss supplement. That’s because of its effect on muscle growth and fat reduction.

This particular drug is not a steroid, but it has some properties similar to those of anabolic steroids, such as promoting an increase in muscle mass. Due to these properties, Clenbuterol has been used in livestock to increase the amount of lean muscle.

What is Clenbuterol used for in training?

Clenbuterol has been observed to both increase muscle mass and reduce body fat. Additionally, it remains in the body with an active effect for up to about six days after consumption. Because of these properties, it’s often used as a weight loss supplement or to enhance athletic performance. People taking Clenbuterol for weight loss or performance enhancement often use anabolic steroids or growth hormones alongside.

Athletes who use Clenbuterol do this in order to burn fat, build muscle, and improve sports performance. The drug is believed to increase the development of skeletal muscle by enhancing muscle protein synthesis. At the same time, it aids in fat loss by increasing the metabolism. The main benefits of Clenbuterol are:

• Increases Metabolism/Burns Fat

• Increases Blood Flow and Oxygenation

• Increasing Protein Synthesis/Build Skeletal Muscle Fibre

• Increased Energy Levels

• No Testosterone Suppression

Appetite suppression and Diuretic effects are also benefits of Clenbuterol, which makes this one of the best weight loss and cutting supplements available on today’s market. Weight loss can be dramatic whilst using Clenbuterol, especially if the user’s eating in a calorie deficit and working out regularly and intensely throughout a cycle.

How much fat you’ll lose will depend on how you respond to the drug, your genetics, diet, workouts, dose and how long you cycle for. However, on average, users can expect to lose 8lbs in 4 weeks. If you combine Clenbuterol with thyroid hormones such as T3, you can increase thermogenic activity even more than cycling this supplement alone.

Recommended dose of Clenbuterol

Bodybuilders will typically take 1-2 tablets a day (40-80mcg), and increase their dose by 0.5-1 tablet every 3 days. In terms of cycle duration, less is certainly more on Clenbuterol. This is because after a certain period of time, this supplement will stop being effective for fat loss, because of receptor down-regulation (decrease in the number of receptors on the surface of target cells, making the cells less sensitive to Clenbuterol).

While on a cycle, these effects usually start to wear off after 4-6 weeks. Thus it’s optimal to keep cycles short and often. You can tell if Clenbuterol’s effects are wearing off by monitoring your body temperature. If your temperature begins to drop, this is a sign of the thermogenic effects of Clen decreasing. Experienced bodybuilders who have built up a tolerance to the drug, can adopt an aggressive dose to burn more fat (some do this before a competition) and take as much as 120-160mcg a day (3-4 tablets).

This being said, when using higher doses, the cycles should become shorter. When running a higher dose, 2 weeks on and 2 weeks off is a common protocol for most athletes and bodybuilders. Also short cycles will prevent your body from getting used to the drug, and thus you can expect good results with each new cycle.

    The Astralean from Alpha is one of the best versions of Clen available. I weightlift and also perform in triathlons and in both aspects, this Clen works perfectly. Over the years I have used other brands that have been inconsistent, but with the Alpha Clen, this does not happen. The results are always the same as long as you cycle per 3 weekly. clerkenwell-london-com provides genuine substances and as long as they contunie to do so, I will be forever greatful.

Hey! Clen has a half life of about 24 hours. The most popular method to use it is the 2 weeks on, 2 weeks off, because the fat burning effect can last up to 5 weeks. Some continue using clen until they meet their desired goal, but for this to happen, you should increase your dose every 2 weeks. Start with 40mcg per day then hold it for a couple of weeks to see how it affects you. After that, you can decide to go higher or lower. Remember that at a higher dose, sometimes, the cons outweighs the pros. Good luck!

Yeah. It’s still good. It’s still safe as long as you stored it in a cool, dry place. It will probably still be potent and will only be not as potent after 5 years.
