On a diet or working out? Are you also on birth control? Maybe you are working out and need to lose weight. Maybe you are having severe asthma. Or it could be that you need to start birth control. 

Now your most important query is: does clenbuterol affect birth control?

Clen is an amine which is mainly used for fat burning during muscle preservation. It is also used to treat asthmatic patients to some extent. However, it does not affect birth control. The effects while taking this are not related to hormones. Hence you can take clenbuterol while taking birth control.

So, let’s dig deep into this and read about what clen actually does or is it really safe to use clen or not.

Clenbuterol or clen in general stimulates muscle protein synthesis by binding the muscle cells. That is the reason why it helps in cutting and muscle preservation. In a nutshell, it reduces body fat and weight.

Does Clenbuterol Affect Birth Control

No, clenbuterol or more commonly known as clen does not affect birth control. Clen mostly is a sympathomimetic amine. But does clenbuterol affect hormones? No, clenbuterol is not directly related to hormones so clenbuterol does not affect birth control directly.

Clenbuterol is a muscle relaxant. It is also used to dilate muscles so that it is easier to give birth during delivery.


It is also a bronchodilator agent. For that reason patients who have asthma sometimes take it. Not only people who have asthma but also the people who have COPD (Chronic obstructive pulmonary disease).

The drug has not been licensed for human consumption inside the United States. It can be only accessed through prescription in certain regions. That is for patients with asthma or other breathing difficulties.

Also, clen is not FDA approved. So I can not guarantee you that it will not affect you in the long run. Moreover, clen is mostly tested on rats. It has not been tested on humans. 

Therefore you should think before you take clen.

What Clen Really Do?

Clenbuterol or clen in general stimulates muscle protein synthesis by binding the muscle cells. That is the reason why it helps in cutting and muscle preservation. In a nutshell, it reduces body fat and weight.

There are mainly two reasons for a person to take clen or clenbuterol.

  • To improve athletic performance.
  • To preserve muscle and help to lose fat

Another fact about clen, is that clen can remain throughout your system for approximately up to 39 hours of ingestion. These specifications are not related to hormones therefore you can take birth control while taking clen.

However, as I said earlier, clen has not been tested on human specimens. Therefore I do not recommend you take it while on birth control.

Does Clenbuterol Affect Hormones?

No clenbuterol does not affect hormones. As I said earlier it is an amine. 

Clenbuterol is a steroid-like (not steroid) chemical. It is in the class of a beta2-adrenergic agonist. This means it activates the beta2-adrenergic receptors of your throats.

This medication helps relax your muscles and lungs, making it easier to breathe. Therefore, asthmatic or similar patients would be really helpful. But then comes to mind does clenbuterol mess up your menstrual cycle?

Clenbuterol and Menstrual Cycle

The menstrual cycle is a natural mechanism for a woman’s body to prepare for and release an egg. Clenbuterol users may notice alterations in their menstrual cycle.

Another noticeable alteration in women is a deepening of the voice. Clenbuterol affects the woman’s voice in the same way as it affects men’s voices. And this is caused by a shift in estrogen levels.

What Are the Benefits of Clenbuterol?

Although clen is banned including its adverse effects. Clenbuterol or clen has been used by many sportsmen for its benefits 

Lower Levels of Androgen

Androgenic adverse effects are less for clen. Clenbuterol is more popular among female bodybuilders rather than anabolic steroids. because it has fewer androgenic adverse effects. 

If you check out ugl steroids, you will know about the adverse effects of normal steroids.


Normal steroids tend to create many negative effects. For example facial hair and also a much deeper voice than usual. But to your surprise clenbuterol is not blamed for causing any.

Quick Weight Reduction

It was said previously that clen enhances metabolism. Due to that reason, it helps to burn fat.

In a research study, two individual groups were put on a strict and very disciplined diet.

While one group was given clen. Keep in mind the other one was not. After ten weeks. The group that had clen in their diet dropped an average weight of about 11.4 kilograms fat. Whereas, the team that did not get clen lost 8.7 kilograms.

But if you are on clen and really need to lose weight. Then I can recommend some products you can try. 

It can help you get rid of unwanted fat. It can also filter out any dangerous obesogens from your body.
This supplement is a natural blend of 22 carefully mixed plants. It is used for fixing the leptin cycle.

These are some products that I liked and I hope you will also like them as well.

Suppression of Appetite

Yes it does suppress appetite. Nevertheless, it is not true for all cases.


Many bodybuilders use clenbuterol to burn fat before a performance or competition. This medication has the added benefit of reducing your appetite. That enables you to consume fewer calories. 

However, not everyone has this impact.

Clenbuterol Side Effects

Some of the most common side effects include:

  • You may experience Heart palpitations
  • Tremors may be experienced
  • You may have Increased heart rate (tachycardia)
  • It might also be Lowered blood potassium (hypokalemia)
  • High blood sugar (hyperglycemia) may happen
  • Anxiety might be triggered
  • Agitation is felt
  • Sweating might be caused
  • Cardiac arrest is a rare case but it happens
  • Feeling hot or warm can also be a side effect
  • Insomnia is a rare case but happens
  • Muscle cramps is felt

If you use stronger doses of clenbuterol to obtain its weight reduction consequences. You are much more likely to face these negative adverse effects. 

This treatment remains in your system for a long time aka around 39 hours. So, you might have adverse effects for up to 8 days. According to studies, more than 80% of clenbuterol users, who have been on clen overdose were hospitalized. 

They are also those people who suffered from the major adverse effects. Someone who is new to the clen diet is more prone to its adverse effects rather than someone who has already been using it. 

Such negative effects can be seen while using clen. You should stop the consumption of clen immediately and you should seek medical assistance.

What Are the Precautions?

It is significant to remember that not all supplements can give us what we need. And some of them may have dangerous side effects. If you feel noticeable changes in your body, you may consider taking a break from supplements. 

If You Have Asthma

In humans, the typical dosing range for treating asthma is 20-40 mcg per day. If you have a clenbuterol prescription, ask your doctor or pharmacist how much and how often you should take it.


So if you have taken tren, you can balance it put with clen. To know more you can check why tren cause shortness of breath.

How Should I Take Clenbuterol For Best Results?

Clen has to be taken in smaller amounts. 20 mg per day has been recommended for starters. And should be continued for up to 3 weeks at least. This helps the body to adjust to clen. But this can vary from person to person.

Your muscles and lungs are relaxed with the help of this medicine. Hence making it much easier for respiration. It can stay in your system for up to 39 hours

How Do I Calm Down From Clenbuterol?
