Our article will discuss the perfect cycle for beginners, how long the drug needs to kick in, and much more information about CLEN. 

Both men and women can take advantage of clenbuterol’s benefits if they stick to an appropriate dosage.

So, which clenbuterol dosage for weight loss is perfect? Keep reading to find out. 

What Is the Best Clenbuterol Dosage for Weight Loss? 

The recommended clenbuterol dosage for weight loss is 60-100 micrograms daily. Because it is a Beta-2 agonist, this drug should be used as asthma treatment and requires a prescription. It comes as a pill and can sometimes be used for COPD. But for weight loss, clenbuterol is available as a pill, liquid, or injection. A clenbuterol 40-micrograms dosage should do the trick if you have never used any anabolics.

If used properly, CLEN should maintain its maximum effect on the body through the entire cycle. The dosage should start low and be adjusted later on with a gradual increase as the body begins to recognize the substance. 

When it comes to clenbuterol dosage for women, the dosage is similar to men, unlike different steroids. However, the dosage should be appropriate for the weight and body size. Another thing worth mentioning is that clenbuterol is dosed in micrograms and not milligrams which requires you to be extra careful. 

Bodybuilders that carry around a lot of muscle and compete at the highest level are known to use 6 to 8 pills a day which equals 120 to 160 micrograms. These dosages are far beyond the therapeutic range in medicine and may offer some side effects

Clenbuterol Cycle for Beginners 

Clenbuterol should be consecutively used for 16 weeks in 1 year. That said, a two-week cycle would be ideal for starting your journey. You can have eight 2-week cycles within a year and maintain your body fat at a low level. Depending on your goal, there is still some wiggle room on when and how much you should use CLEN. If you need to be prepared for a show or just like to get ready for the beach, you can time the cycles better. 

If you are a beginner and like to start a cycle for the first time, you must be open-minded and patient. You should not increase the dosage immediately if you do not see results. The entire process should be carefully planned with a strategy followed by a strict diet and a workout regimen. 

Typically, a great dose for beginners would be 20 micrograms per day with an increase of 10 micrograms every 3 days. The maximum dosage at the cycle’s end should be between 80-100 micrograms daily. 

2 weeks on/2 weeks off CLEN cycle 

A short cycle of two weeks can prevent the body from building a tolerance to the drug and ensuring fat loss in future cycles. A cycle of 14 days may also offer a reduction in cardiovascular strain.

However, remember that the second cycle begins with the maximum dose from the first one. For instance, if you finished the first cycle on 80 micrograms daily, the second cycle should use that dose as a starting point. Some people have been known to mix clenbuterol with Winstrol or Anavar for faster results. 

Benefits of Clenbuterol

As we mentioned, when taken in the appropriate amounts, clenbuterol may offer a lot of benefits, such as: 

  • Fat loss
  • Blood flow increase
  • A rise in energy levels
  • Appetite suppression
  • Diuretic
  • No testosterone suppression

Fat loss 

How much weight can you lose with clenbuterol, you ask? Over 12 weeks, you can shed 6 and a half pounds of fat. 

By stimulating the central nervous system or the CNS, clenbuterol increases the body’s temperature and the adrenaline by 1 degree. The body utilizes the sweat glands to cool down and achieve normal temperature to maintain homeostasis. This cooling effect increases calorie expenditure, allowing people to burn more calories than they typically would. 

Blood flow increase

With the increase in adrenaline levels, clenbuterol turns the fight or flight mode of the body. Thus, consequently increasing the blood flow through the entire system. For the same reason, the drug has the potential to improve muscular endurance and help people do more reps in the gym than before.

A rise in energy levels 

Because clenbuterol is much more powerful than caffeine-filled pre-workouts, it should increase energy levels through the roof. Operating as a powerful stimulant, clenbuterol may cause the body to release more adrenaline and a powerful burst of energy. 

Appetite suppression 

This drug has a stimulating effect on the beta 2-adrenergic receptors, which are connected to the safety levels of the body. This means that, during a clenbuterol cycle, the individual might not feel the need to eat throughout the day.

This fact is further associated with fat loss because people do not need to eat high-calorie dense foods or binge eat while watching every Netflix release. 


Clenbuterol also has the properties of a diuretic, and despite helping people to lose weight, it may also flush out extracellular water. 

No testosterone suppression 

The biggest side effect of any anabolic is the shutting down of the natural production of testosterone. After a cycle, people need some time to reach the normal test levels, but with clenbuterol, the test levels are not compromised. At the end of the cycle, post-cycle therapy is not needed. 

Side Effects of Clenbuterol 

If you step over the boundaries and disregard our information about clenbuterol dosage for weight loss, the drug may harm your body and system. The most common side effects of too much CLEN or improper cycle are heart rate increase, anxiety, and insomnia. 

Frequently Asked Questions

What does clenbuterol do to your body?

Low doses of CLEN might help with asthma. The drug may increase the body temperature and achieve a state of thermogenesis. When the energy levels are up, the metabolism is primed to burn more calories than usual. This may drastically diminish your overall weight. 

Is clenbuterol good for weight loss? 

Because it can increase the metabolism and the body’s energy levels and suppress the appetite, clenbuterol should be an excellent anabolic for weight loss. 

Does clenbuterol count as a steroid? 

Because CLEN can be bought in a pharmacy with a prescription as an asthma medication, it is not considered a steroid. It just mimics steroids and has a reputation for being a “non-steroidal steroid”. 

Why is clenbuterol banned in the US? 

Clenbuterol is banned in the US by USADA. This is because the drug promotes anabolic properties, whether that is for muscle growth or fat loss. Plus, CLEN is not legally distributed in America, and the FDA does not approve it for humans or animals. 

Can you fail a drug test for clenbuterol? 

The answer to this question depends on the test. If you are being tested for PED usage, clenbuterol will not show up. However, a urine test, CLEN can show up 7 to 10 days after injection. If that happens, you can always say that you have asthma. 

Does clenbuterol affect sperm? 

If taken in large quantities for a longer period, clenbuterol can affect a person’s sperm and fertility. But, if you stick to the clenbuterol dosage for weight loss that we explained, a study shows that the sperm will not be affected in any way. 

How long does CLEN take to kick in? 

According to the Drug Enforcement Administration, the effect of CLEN can kick in after half an hour up to 3 hours. You will experience an increase in energy levels. But, you must wait at least 2 weeks to see visible results on your body.
