Clenbuterol: How Does It Work?

Not everyone is familiar with clenbuterol. In fact, there are many people who have been using this drug without knowing what it really does. They use it for weight loss and energy boost or as a fat burner. However, the real value of clenbuterol is in its ability to improve endurance and reduce recovery time after workouts, just like steroids do. That’s why you often see bodybuilders using clenbuterol along with other muscle-building drugs such as Deca Durabolin or Anadrol. The purpose of this article will be to find out whether it’s true that clenbuterol can significantly increase weight gain when combined with steroids as well as which combinations are the best ones. We’ll also look into the question of whether clenbuterol preserves lean muscle mass or not.

Clenbuterol – Let’s begin by talking about the drug itself. As you already know, clenbuterol is a beta-2 stimulator which means it gives you energy and helps burn fat without any muscular effort on your part. This drug was originally used by asthma patients but slowly became famous with bodybuilders because of its ability to burn calories without affecting existing muscle tissue. The most interesting thing about clenbuterol is that scientists designed it as an alternative to Anavar (oxandrolone) for weight gain purposes.

Clenbuterol’s Mechanism of Action

Clenbuterol increases the level of thyroid hormones T3 and T4 in your blood. It also boosts your metabolism which is why it’s so effective as a fat burner. It would be wrong to think of clenbuterol as a magical drug, however. You must use it for at least 2-3 months consecutively without missing more than two weeks of dosage if you want to see all its benefits. The maximum realistic results are reached after 8 weeks of continuous usage, but some people claim they’ve seen even greater effects having used the drug for 11 or 12 weeks straight. By that time, you’ll notice that your pulse is getting faster, your heart rate higher and that the amount of blood circulating through your system is constantly increasing.

Clenbuterol comes in the form of a tablet. It’s now used in veterinary medicine, such as asthma relief in horses. There have been attempts to develop substances containing Clenbuterol for muscle loss diseases, such as sarcopenia and HIV, and cancer.

The mechanism of action of Clenbuterol is like the beta2 andrenoceptor agonist, which means it targets and stimulates these receptors. There’s only one way to receive this stimulation – by taking Clenbuterol. It can also be used as an alternative for those who cannot take Ephedrine since it doesn’t contain any of the banned substances found in Ephedrine (ephedra).

How Does It Work?

Clenbuterol, the most popular fat burner out there, works by increasing body temperature. It produces strong thermogenesis effects because it stimulates your nervous system and metabolism to produce heat. If you increase your core body temperature, you’re likely to boost your energy levels as well as improve thyroid hormone production (including T3), which is responsible for revving up your metabolism. Clenbuterol achieves this by stimulating the beta-2 receptors in the smooth muscle cells of the respiratory system. This drug thus dilates the bronchial tubes and warms them up so that they can hold more oxygen before exhalation. That’s why clenbuterol has become so common among athletes who are seeking an edge over other competitors. The good news is that you don’t have to take it every day.

Positive Effects of Clenbuterol

As already mentioned, one of the main reasons bodybuilders use clenbuterol is because it helps them boost their metabolism. It’s not just that – Clenbuterol also acts as an appetite suppressant which means that you can eat less than before and still feel full all the time. This drug will also bring your energy levels to peak performance.

Bodybuilders respond the best to clenbuterol. The following are some of the positive side effects it can cause:

  • Increase of muscle mass.
  • Decrease in body fat.
  • Increase in strength.
  • Increased stamina and endurance, which makes it very popular with athletes, especially sprinters.
  • Anti-catabolic property – Clenbuterol has an anti-catabolic effect, which means it helps you retain the muscle mass you currently possess.
  • The anabolic effect is moderate- making this drug even more desirable to bodybuilders.

Negative Side Effects of Clen

Even though the majority of clenbuterol users see nothing but benefits from this drug there are some side effects you should know about. Even if you stick to the recommended dosage, they can be more than enough for you not to make use of clenbuterol ever again. The most common side effects include:

  • Increased heart rate (tachycardia) and high blood pressure (hypertension)
  • Insomnia or sleeplessness
  • Nausea
  • Headaches
  • Vomiting
  • Rapid or irregular pulse
  • Dizziness

You should also remember that clenbuterol has a thermogenic effect which basically means it increases your body temperature while you’re using it. You might need to drink plenty of water if you don’t want to feel nauseous, vomit during training and even faint on the gym floor. If you have any cardiovascular problems underlined by high blood pressure, insomnia or suffer from Raynaud’s disease then avoid taking clenbuterol altogether because the probability of side effects is much higher in these cases. It would be a good idea to get a thorough checkup before starting with this drug.

Clenbuterol Cycle

A clenbuterol cycle can be short or long depending on your goals and the dosage. A standard clenbuterol cycle would last 4-8 weeks at 40mcg pills, 3 times per day. The first dose should be taken right when you wake up with breakfast, the second 20-30 minutes before lunch and the third one just before you hit the gym to workout. This way you’ll get two main benefits of taking Clen – burning fat while building muscle at the same time since this drug works as both a thermogenic agent and metabolic stimulant. If you want to experience only weight loss effects, then it’s recommended to take clenbuterol for 8 weeks straight without missing any dosages. Taking breaks is not recommended. It’s always better to space your clenbuterol cycle with 2-3 months of PCT (Post Cycle Therapy).

The total daily dose should never exceed 140mcg and it’s recommended to start with a lower dosage to see how you react before increasing the quantity. Women should be extremely careful when taking clenbuterol because they’re more sensitive than men and can experience side effects much faster. The risk of negative repercussion increases if you stack other stimulants such as ephedrine, caffeine, or any other similar product together with Clenbuterol. Males shouldn’t take clenbuterol unless they have reached the age of 21 at least due to the fact their bodies still haven’t finished developing yet which makes them more likely to experience side effects.

Clenbuterol and Oxandrolone Combination

Clenbuterol has a thermogenic effect which represents one of the main reasons why it’s so popular with bodybuilders. It helps to increase your heart rate and blood pressure, boosts your metabolism and cravings for food are suppressed. All these benefits combined make this drug extremely efficient in cutting cycles when you need to get rid of unnecessary fat quickly before competition or simply just want to have that summer beach body next year.

Oxandrolone has an anabolic nature but it’s mild compared to other similar products such as testosterone, methandienone, etc. Therefore, Oxandrolone is commonly stacked with clenbuterol during cutting cycles because they complement each other perfectly. Clenbuterol will provide additional fat-burning effect while Oxandrolone will help to preserve lean muscle tissue. Not only that but clenbuterol has also anti-catabolic properties which means it can suppress cortisol hormone levels which is why this product is perfect for people who like to do long cycles of 12 weeks or more.

The best clenbuterol cycle for men would include taking 60mcg-140mcg of clenbuterol per day with 40mg of oxandrolone (Dianabol) each day for minimum 8 weeks. The dosage must be split between 3 main meals, and you shouldn’t take the last clenbuterol dose right before sleep because it might keep you awake at night.

Clenbuterol Cycle for Women

Female bodybuilders aren’t taking clenbuterol to cut body fat, they take it mainly to develop and tone muscles while reducing extra water retention which helps them achieve more defined and ripped look next competition. However female bodybuilders must pay even more attention than men when stacking clenbuterol with other drugs such as Oxandrolone because they’re way more sensitive and prone to side effects. 80mcg per day split into 3 doses will be enough for women only during the first month of their cutting cycles to get that lean toned look without any visible muscle mass gain. All dosages should be taken around 8am, 12am and 4pm.

The Most Recommended Dosage for Clenbuterol

The popular dosage is 40-120mcg per day. Clenbuterol is perfect for the last weeks of cutting cycle when you’re already lean enough but still want to get rid of that stubborn body fat that’s hiding your muscles. It’s best to take clenbuterol 40-50 minutes before breakfast for maximum results. Women are recommended to stay within 80mcg/day while men can go up to 140mcg/day max only if they tolerate well this product and haven’t experienced any side effects. Those who stack it with other products such as T3 or testosterone might need higher dosage to achieve same results which is why I recommend taking breaks every 8 weeks or so to let your body recuperate for a few weeks before restarting your cutting cycle once again.

The best clenbuterol cycle for women would include taking 40mcg per day which should be split into 3 doses, taken around 8am-12pm-4pm during the first month of their cutting cycles to get that toned lean look without any visible muscle mass gain. All dosages should be taken with at least 8oz of water.

A Clenbuterol cycle which is highly recommended is the following:

80 mcg Clenbuterol – 2 sprays under the tongue twice a day for 14 days, followed by 2 weeks off.

This cycle will help you preserve lean body tissue while burning extra fat deposits accumulated due to intense lifting sessions. It’s also good for helping you achieve that extra pump during workouts.

The Clenbuterol dosage will be divided into 2 doses taken 40 minutes before breakfast and lunch, with at least 8 glasses of water daily. This product is known to cause insomnia so to make sure you don’t take it too late during the day or else it may keep you awake at night (I’ve experienced that). Don’t take more than 3 weeks without interruption because your body will become tolerant to Clenbuterol if used constantly.

You should prepare yourself in advance and start doing cardio in the morning before breakfast for at least 30 minutes to get rid of excess water in your body. Make sure you don’t overdo it and stay hydrated during these sessions with sports drinks such as Gatorade or Powerade which will help you replenish electrolytes lost due to perspiration.


Clenbuterol is a powerful fat burner that is safe to use if you follow all precautions and recommendations. It’s usually stacked with other steroid products such as T3 or Testosterone Enanthate to achieve maximum results, especially for men who want to bulk up and gain solid lean muscles mass. However, it shouldn’t be used constantly due to its strong stimulating effects on the heart so it’s best to include short breaks every 8 weeks or so when using clenbuterol regularly.

For women, however, Clenbuterol can be used during the first month of their cutting cycle only since they’re way more sensitive and prone to side effects than men due to their low testosterone levels. Also, it should never be stacked with another product since it’s a thermogenic and fat burner that will help you burn excess water and body fat while preserving lean muscle mass.

Before starting any Clenbuterol cycle make sure to consult your physician to get the green light especially if you have heart problems or other conditions that may interfere with Clenbuterol side effects such as insomnia or anxiety attacks. It should never be used by women who are still growing because it can cause infertility issues and growth of facial hairs, not suitable for teenagers under 18 years old either so keep that in mind before purchasing this product online without getting a prescription from your doctor first.
