This clenbuterol before and after article will provide you with information on clenbuterol cycles, how clenbuterol works, clenbuterol reviews, clenbuterol side effects.

Review of Clenbuterol

body fat

Clenbuterol was originally created to help people with asthma breathe better. Clenbuterol aids in the opening of the patient’s airways, allowing for improved breathing and oxygen intake. Researchers later found that clenbuterol activates beta-2 receptors, which stimulates fat loss by stimulating thermogenesis.

Thermogenic = increase in body temperature

Thermogenics accelerate fat loss by forcing the body to work hard to regulate your temperature back down to normal. As a result, epinephrine is secreted from the adrenal glands, increasing a person’s heart rate, and metabolism speeds up dramatically.

Despite the fact that clenbuterol does not have any anabolic effects; it may increase a person’s metabolism, which will help them burn more fat during a cut. And when bodybuilders’ energy levels start to drop on lower-calorie diets, they’ll benefit from this extra adrenaline as well.

  • If you’re chubby, clen will make you slim.
  • If you’re lean, clen will get you ripped.
  • If you’re very lean, clen will get you shredded.

Clenbuterol is a chemical that helps to increase muscle mass while reducing body fat. Bodybuilders often take clenbuterol 2 months before a competition, when they are attempting to achieve incredibly low levels of body fat – less than 4%.

How Clenbuterol works?

anabolic steroids

Clenbuterol is a thermogenic cutting agent that boosts a person’s metabolic rate by increasing their whole body temperature.

For a variety of reasons, various athletes and gym-goers use clen. Athletes utilize clenbuterol as a performance enhancer, increasing their energy levels/endurance by opening up their airways for improved oxygen delivery to their muscles. As a result, clenbuterol was developed as an asthma medication.

Clen’s ability to burn fat can assist make an athlete more functional since they will be lighter (especially advantageous in endurance sports).

The most common use for clenbuterol is in a cutting cycle to assist bodybuilders get more shredded. This can be for personal reasons or because they are about to compete on stage against other bodybuilders.

Clenbuterol benefits are

Fat loss

burn fat

Clenbuterol is a beta-2 adrenergic agonist, which means it activates the brain’s central nervous system and stimulates the release of adrenaline, and increases body temperature by up to 1 degree.

As a result, in an effort to restore homeostasis, the body activates the sweat glands to cool down and return to their previous temperature.

Users who constantly experience a “cooling effect” throughout the day tend to burn more calories over the course of their stay.

As a result, people will generally burn more calories at rest than usual.

This is beneficial to bodybuilders because it makes it easier for them to lose fat by eating in a calorie deficit and burning calories indirectly (as a result of a high metabolism).

By speeding the conversion of triglycerides to free fatty acids, clenbuterol also has direct fat-burning effects (similar to other beta-2 agonists).

Increased blood flow

burn fat

Clenbuterol activates the sympathetic nervous system, which puts the body into a state of fight or flight. As a result, blood flow throughout the body increases as a survival reaction.

Clenbuterol has the ability to enhance muscular endurance, allowing bodybuilders to complete more reps in a shorter amount of time.

Pumps can get larger when the circulation of blood to the muscles improves. Increased reps and bigger pumps may help you grow new muscle by stretching of the muscle fascia.

Fascia is a connective tissue that surrounds muscles and can restrict muscular development. Muscle growth can be hampered if the fascia is too tight. As the muscle attempts to expand, it pushes against the deep fascia, which is more flexible.

Larger pumps from clenbuterol will assist your fascia to become more flexible, lowering friction. Increased circulation throughout the body will also be beneficial to those who do cardiovascular exercises. Users also state that they experience faster recovery after workouts and need less sleep than usual.

Note: Cortisol levels can increase excessively when a person is in fight or flight mode for an extended period of time, with vasoconstriction occurring as a result. This reduces blood flow and makes people tired; this may happen during the latter phases of a clenbuterol cycle after blood flow has increased.

Enhanced energy

clenbuterol cycle

Pre-workouts are popular since they contain stimulants, such as caffeine, which stimulate the central nervous system and cause the body to release extra adrenaline.

Clenbuterol is a strong stimulant, more so than any other pre workout on the market. As a result, energy levels will be through the roof. What goes up must come down, however. Users may experience a decrease in energy after this initial buzz wears off; as a result, they become reliant on clenbuterol.

It’s true that fat burning is enhanced by increased energy levels. Due to your workouts getting more intense, your energy levels will (indirectly) help you burn greater amounts of fat. For example, you may ride a stationary bike for 15 minutes on clenbuterol, but you may extend this to 20+ minutes when cycling on clenbuterol.

Appetite suppression

clenbuterol cycle

Clenbuterol has an enhancing impact on beta 2-adrenergic receptors, which can influence satiety levels in people. As a result, while on a cycle, users may not feel as hungry throughout the day; nevertheless they are burning more calories.

Users will be less inclined to cave in and binge eat their favorite high-calorie meals since to the heightened sense of fullness associated with clenbuterol. Clenbuterol has this effect on users because they are less likely to cave in and binge eat their favorite high-calorie foods; therefore, they get fuller for longer periods.


lose weight

Clenbuterol works by flushing out extracellular water, which can make a person appear leaner and have greater muscle tone. The amount of sweating that occurs as a result of clenbuterol is responsible for its diuretic effects. As a result, it’s critical to drink enough water while taking clento avoid dehydration and muscular cramps.

Water lost as a result of taking clenbuterol will be restored following the cycle, making this diuretic action temporary.

No testosterone suppression

anabolic steroid

One of the most significant disadvantages of anabolic steroids is the inhibition of natural testosterone production.

Following anabolic steroid use, it might take weeks or months for natural testosterone to return to normal.

However, clenbuterol (as opposed to anabolic steroids) has no negative effect on testosterone. As a result, you don’t have to worry about losing your gains or going through the PCT process.

Clenbuterol dosage

Planning how you’ll gradually increase the dose throughout a cycle is an important aspect of determining your Clenbuterol dosage. This must be done as your body becomes accustomed to the drug’s effects. The best fat-burning results are achieved by starting a cycle at a low dosage and slowly increasing it over two weeks.

For most people, this entails beginning a cycle at the lowest effective dosage and gradually increasing it to the maximum recommended dose by the conclusion of the cycle. The typical daily dose for most individuals is between 120mcg and 160mcg.

The safety of the individual taking Clen is considered. Starting on a high dose is dangerous, and there are various reasons behind it. A two-week break is then required, and if another cycle is started at the same dosage, it will begin 20 micrograms (mcg) higher. The suggested increase in dosage to reach a new level is 20 micrograms (mcg).

Some people believe it’s good to gradually reduce Clen’s dosage towards the end of your diet and fat loss cycle, just as we increase its dose over time. However, there is no evidence that this is required or beneficial. For about a week, simply cut the dose down to what you began the cycle with (usually 20mcg or 40mcg) and then stop clen completely.

Clenbuterol cycles

As I’ve previously mentioned, the most common and accepted approach for Clenbuterol dosing is to gradually increase throughout the cycle, so you start low and easy, get used to the effects, and gradually raise your dosage.

Let’s take a look at what a more focused Clen cycle might look like. Keep in mind that individuals who seek to reduce weight for competition may have different cycles than those who are using it for bodybuilding or just wanting to meet personal fat loss objectives since it is utilized by people with a wide range of personal goals.

The distinctions between them don’t reside in the technique for using Clen, but rather in what you can put it with – some people prefer to use just Clenbuterol, while others will mix it with anabolic steroids as part of a more extensive cutting program.

Clenbuterol, on the other hand, should not be misconstrued as an anabolic steroid in which doses and cycles vary considerably depending on objectives. Clenbuterol, on the other hand, is employed quite similarly by both beginners and experts, with novices and intermediate athletes being the only notable exceptions.

Clenbuterol only cycle

The following Clenbuterol cycle example is appropriate for most people. This cycling consists of two weeks on, two weeks off. For the second two weeks, Clen is taken daily. After that, Clen is stopped for another two weeks before being restarted again. The following figures show daily dose amounts:

  • Day 1-2: 20mcg
  • Day 3-4: 40mcg
  • Day 5-6: 60mcg
  • Day 7-8: 80mcg
  • Day 9-10: 100mcg
  • Day 11-12: 120mcg
  • Day 13-14: 140mcg

When the dosage reaches a maximum of 140mcg, the process is halted. After two weeks, there is a two-week break. When resuming your cycle, however, the dosage does not start at the lowest level; instead, it begins where you left off during the previous cycle at 140 mcg. The same amount is maintained for two weeks throughout the second cycle.

Clenbuterol cutting Cycle

The following cycle is intended for persons who use Clen as a standalone fat-loss supplement. What about bodybuilders who just use it as one component of a cutting regimen? Consider this example of an 8-week plan:

  • Clenbuterol: 120mcg daily
  • Anavar: 80mg daily
  • Trenbolone: 200mg weekly
  • Testosterone Propionate: 100mg weekly

The cutting cycle shown here makes use of the potent fat loss drug Anavar, which will be amplified by Clenbuterol. The above cutting regimen is only for people who are aware and capable of handling steroidal side effects.

Advanced Clen cycle

This is an advanced 8-week Clen cycle:

  • Testosterone Prop: 100mg/week (25mg/eod)
  • Tren Acetate: 200mg/week (50mg/eod)
  • Masteron: 400mg/week (100mg/eod)
  • T3: 90mcg/day
  • Weeks 1-2, 5-6, 8+: Clenbuterol at 120mcg/day

*eod – every other day

*T3 is an additional fat burning agent

Clenbuterol results, before and after

post cycle therapy

Expect to lose body fat more quickly while taking Clen than if you didn’t use the drug, but continue to exercise and eat in the same (or better) way. While not a muscular builder, Clen can help your body appear more muscular and toned by removing fat that would otherwise hide away muscles.

There are a few things we need to understand in order for Clenbuterol to work effectively and produce the results you desire:

  • If you have been trying to lose fat in the stomach, hips, or thighs but haven’t had much success with other methods, Clen is a good choice. You should be lean and want to use Clen to burn away stubborn fat or fatty deposits that you’ve struggled to move using other approaches.
  • Diet is crucial and no amount of Clen will help someone lose weight if they eat too much, eat the wrong type of food, or simply consume more calories than they burn.
  • Exercise is important, and while the type of exercise you do depends on your lifestyle and your goals, we must keep in mind that Clenbuterol increases what you already do and improves your results.

In other words, you should already be burning more calories by exercising than you consume, because maple can help you ingest and burn that stored fat during the most critical period of your fat burning program.

Clenbuterol side effects

lean muscle

It should be remembered that clenbuterol is by nature a stimulant. This means that it will have potential side effects, and are more likely to get worse and worse the higher your dose of this compound. Just as caffeine is a stimulant, and we can expect some side effects when consumed in large quantities, so is Clen.

Again, as with caffeine, individual reactions to clenbuterol will vary; however, it is important to be aware of the potential side effects you may experience so that you can control them and adjust your dose accordingly to get maximum benefit and minimal side effects.

I can classify the side effects of clenbuterol as common ones that most people are likely to encounter and those that are considered less common.

The following are the most common side effects of clenbuterol. Not everyone will experience all or even some of them, while other people may experience everything; it depends on your personal sensitivity to stimulants and of course on your dose.

Jitters or tremors

You may notice that your hands are shaking when you stretch out your fingers. Of all the possible side effects, this is usually reported by clen users. as with most side effects, they will probably slow down as your body gets used to clen, so doses should start at a low level and slowly increase.

Increased sweating

Clen is a stimulant that warms both the body and the body’s reaction to elevated temperature- This is increased sweating. When cells produce and emit more heat than normal, your body temperature rises, and some people find that they sweat more than usual, either during exercise or at rest.


This is a problem that can arise from any stimulant that can be consumed even with coffee. Very sensitive people may find it difficult to fall or sleep while using clen. The half-life of this medication, more than 36 hours, means that it will always be in your system for 24 hours, including the time when you need to sleep. Lower doses can alleviate severe insomnia by allowing your body to get used to the effects by slowly increasing the dose during the cycle.


All kinds of stimulants can cause headaches, and again, this will be a symptom that varies greatly from person to person. Some people are very sensitive to stimulants (so if you are prone to coffee headaches, Clen can have the same effect on you), while others will never have headaches, even if they use Clenbuterol in the maximum dose. One of the main causes of headaches when taking Clen or any stimulant is high blood pressure.

Increased blood pressure

This will most likely happen at the beginning of the cycle, before the body gets used to the stimulating effects of Clen. If you have had problems with blood pressure, it is very important to monitor your blood pressure throughout the cycle; however, those with a history of high blood pressure and related conditions are advised not to use Clenbuterol.

Muscle cramps

The presumed cause of muscle cramps that many people experience when using Clen is related to a decrease in the level of the amino acid taurine, which can affect the nerves, which in turn plays a role in muscle contractions. When the muscles cannot relax as usual due to the lack of taurine, muscle cramps occur. The recommendation for everyone who experiences muscle cramps when using Clen is to take a quality dietary supplement, and this will probably enable the control of this side effect.


This is a possible side effect of almost all medications and another reason why we start taking Clen in small doses. In more sensitive people, nausea can lead to vomiting, then it is recommended to maintain a lower dose for a longer time and increase it more slowly.

Mood changes

This can range from feeling better while taking the medicine to anxiety and depression when you stop taking Clen.

Other more serious but less common side effects are listed below and are significantly more common when the dose of Clen exceeds the recommended:

  • Rapid or irregular heartbeat
  • Vomiting or diarrhea
  • Fast breathing
  • Very high blood pressure

In all cases of any of the above symptoms, the use of Clenbuterol should be stopped immediately and medical attention should be sought if these effects do not disappear soon after stopping the drug (given the long half-life of about 36 hours).

Those who take Clen for the first time are more likely to have worse side effects than people who have used it for some time. It may take some time to get used to Clen, but if the side effects are unbearable, it is better to reduce the dose until any side effects become more manageable.

Clenbuterol post cycle therapy

Anabolic steroid users are accustomed to post-cyclic treatment to restore natural hormonal function and maintain hard-earned results. But do you need PCT when you use Clenbuterol?

Post-cycle treatment is not necessary if you are using Clenbuterol alone. The standard procedure is to simply stop using Clen for at least two weeks and that is all that is needed.

Unlike steroids, Clen does not affect your hormonal function, so PCT is not needed. However, if you use Clen as part of a steroid cycle, PCT must be applied as needed for the steroids you use.


Is Clenbuterol legal?

Yes, Clenbuterol is technically legal in the United States and other countries, because it is not listed in the Controlled Substances Act.

However, it is not approved by the FDA, so users must be aware of its potentially harmful side effects.

Clenbuterol is also on the list of banned substances of WADA, so athletes can still miss a drug test and be suspended (if they find it stays in their bodies).

Weight loss from Clenbuterol permanent?

Yes, all Clenbuterol results are permanent and will not be undone after a cycle.

However, a person must continue to play sports and eat properly if he wants to maintain his results.

Note: water loss is the only temporary effect, so users can get a small amount of fluid when they finish their cycle.

Will Clenbuterol show up on a drug test?

The legality of Clenbuterol varies around the world. It is not approved by the FDA for human use in the United States. Clenbuterol is a World Anti-Doping Agency classified as a banned substance, so if you test in accordance with the regulations of that agency, Clenbuterol will appear on the test and be considered banned.

It is important to note that there are some reports of the presence of Clen as a result of meat contamination, as the substance is known to be used to increase muscle mass in cattle, although such use is banned in the United States and Europe.

Is Clenbuterol safe?

Clenbuterol is not approved for human use by the Food and Drug Administration, indicating its toxic nature.

The Medical Faculty of the Beijing Union in Beijing, China, concluded that Clenbuterol has only moderate effects when given to rabbits.

However, when higher doses were administered, their heart rate increased dramatically, causing severe hypotension.

Therefore, studies show that the safety of Clenbuterol may be dose-dependent.

It is clear that in higher doses it is not safe in terms of the cardiovascular system.

Note: Men and women with pre-existing heart problems are at greater risk when taking Clenbuterol (regardless of dose). In addition, if users combine Clenbuterol with anabolic steroids, heart-related side effects will worsen.
