With the right Clen dosage cycle, this drug can be a great performance enhancer. It can improve an athlete’s workout routine making it more efficient and more productive.
Clen is a multipurpose drug that works by activating the body’s adrenergic response. Officially, Clen was originally developed for treating different medical conditions such as asthma.
It is a beta-receptor and bronchodilator that acts as a stimulant and opens the airways making it much easier for asthma sufferers to breathe and remain calm.
It also has anti-catabolic and thermogenic properties that are beneficial to bodybuilders and people who are trying to lose weight.
Dominantly, bodybuilding and athletic communities see Clen as an agent to help lose fat. Buy Clenbutrol online here.

Depending on what Clen is being used for, the dosage will vary.
For medical conditions such as asthma, Clen was administered in doses of 20-40 mcg daily as per the existing guidelines of Clen prescription.
Though Clen is no longer prescribed to patients in the US, this gives you an idea of the medically prescribed limits of Clen administration.
This may not relate to the dosage that would be required for fat loss since a lot of physique builders exceed medically recommended dosages of performance-enhancing drugs.
Clen has sympathomimetic properties and, as a result, if high doses are administered at too rapid a pace, or are increased rapidly, it might lead to a high level of discomfort and on some occasions might also lead to death.
Hence, bodybuilders strongly recommend that the dosage be increased gradually over a period of time until it reaches the required level of dosage.
The way in which a body adapts to Clen can vary based on the individual. The typical dosage of Clen is 20 mcg tablets, and in some cases, you will also be able to find tablets with 40 mcg, 50 mcg, and up to 100 mcg.
Assuming that the peak dose is 120 mcg a day, listed below is a common daily dosage for male bodybuilders:
- Day 1-3: 40 mcg/day
- Day 3-6: 60 mcg/day
- Day 6-9: 80 mcg/day
- Day 9-12: 100 mcg/day
- Day 12+: 120 mcg/day
Clen dosage cycles for men and women normally vary due to the differences in their metabolism, Body Mass Index, and overall level of activity.
The dosage given will also be determined by what it is to be used for.
Because of the nature of the drug, beginning with a smaller dose and building up the body’s tolerance until it reaches a maintenance level is standard practice.
Liquid Clen dosage cycle – Liquid Clen is available for individuals who have difficulty swallowing pills.
The dosage for the liquid drug is similar to pills and should be followed according to the manufacturer’s direction.
Just as every use requires a specific amount of the drug to be used in a particular way, the physical health of the person who is taking the medication will also need to be taken into consideration to ensure the proper dosage is given.
Because Clen hydrochloride is considered to be such a powerful stimulant, monitoring by a physician is important to prevent dangerous situations and control adverse side effects and reactions.
Clen Dosage Cycle Chart
The way in which a body adapts to Clen can vary based on the individual.
The typical dosage of Clen is 20 mcg tablets, and in some cases, you will also be able to find tablets with 40 mcg, 50 mcg, and up to 100 mcg.
For practical purposes, 20 mcg can be considered a standard dosage.
But to achieve a high rate of fat burn individuals often incorporate dosages of 120 mcg-160 mcg per day.
However, physique builders recommend the dosage is not started immediately so high. Instead, the dominant recommendation is to increase dosage at a gradual pace.
This is a safety precaution that is promoted to ensure that there is no adverse impact on the body.
Starting from 20 mcg a day, it is believed to be safe in bodybuilding circles to increase the dosage by 20 mcg every other day, as the body adapts.
In case individuals have a lower sensitivity to Clen, some claim they can increase the dosage at a faster pace and there will not be any impact on the body.
In some cases, individuals also have hypersensitivity to Clen and other related stimulants. In such cases, it is felt that the dosage is increased at a slow pace.
Irrespective of the rate at which the pace is increased, the end goal for many users is to have a daily dosage of 120-160 mcg per day to achieve fat loss, based on the tolerance and sensitivity of the individual to Clen and stimulants.
The limit identified by many bodybuilders is 160 mcg per day.
The max dosage for men and women is as follows:
- Dosage for men: 160 mcg per day
- Dosage for women: 100 mcg per day
- Dosage for weight loss: 100 mcg – 140 mcg per day according to need
It is believed that exceeding this amount in any case as it poses a health risk. Over a period of time, the human body is reported to get adapted to the stimulant effects of the compound.
Clen Dosage Cycle Chart for Men
After day 12, 120 mcg/day is often maintained for a period of 2-4 weeks.
Users are said to observe fat burning periods typically for 4-6 weeks before the Beta-2 receptor down regulations start.
It can take 2-3 weeks to surface in some individuals based on factors like genetics and age.
When the receptor levels fall, consumption of Clen is typically stopped for a span of at least 2 weeks so that the Beta-2 receptors regulate again before drug consumption resumes.
Another commonly used option to do the same is by using Ketotifen Fumarate, an antihistamine drug that is proven as per studies to regulate Beta-2 receptors.
Ketotifen is believed to be advantageous as it is taken to allow an individual to continue using Clen without having to take a break, while still regulating the Beta 2 receptors.
When individuals cannot afford to take breaks, this is often held to be the most feasible solution. Reportedly, Clen can be taken at 120mcg/daily following the above dosage schedule for 8 weeks if the individual uses Ketotifen every second week.
However, the usage of Clen is generally not used for a period of over 8 weeks as it has known side effects on the body.
Clen Dosage Cycle Chart For Women
Similar to how individuals increase the dosage of Clen over a period of time, it is suggested in underground communities of PED users that people scale down in a similar manner.
This approach is incorporated into this dosage schedule for females.
This is felt to be a personal choice and some individuals are reported to have gotten off Clen immediately without any side effects or adverse impact. Other individuals claim they will crash due to sudden stoppage.
It is up to individuals to decide on how they wish to stop using Clen.
The ideal is considered to be a gradual decrease in dosage over a period of time, just like how the dosage is ramped up when users start using Clen.
This way, it is said, apparent crashes claimed by many users can be avoided.
The response to Clen can largely be the same in both men and women.
However, the body weight and mass tend to influence the dosage, often resulting in a division based on the gender as females are mainly of lower weight, body mass, and overall size when compared to men. They are believed to be more sensitive to Clen.
The gradual increase in dosage can be the same for both men and women and in the case of women, the peak recommended dosage is dominantly held to be between 80 mcg to 100 mcg daily.
There are reports that indicate women are tolerant to up to 120 mcg dosage daily, which is a sizeable dosage. There are no formal recommended dosages of Clen for fitness or bodybuilding, as there isn’t robust data on this application.
Anecdotally, bodybuilders typically say it varies based on the sensitivity of individuals to the stimulants.
The genetics of an individual, age, and other conditions are also said to play a major role in determining how the body reacts to Clen and other stimulants that are present.
Fitness enthusiasts will say it is ideal for individuals to slowly increase the dosage over a period of time until they figure out the optimal dosage and their tolerance, based on the observed effects of Clen with increasing dosage.
Clen Dosage Cycle Instructions
Clen is used primarily to burn fat, and it is understood that there is little that can be changed about the range of dosages users can take.
Typically, people who choose to use Clen do so because they believe it has a powerful fat-burning capability that can help give them the edge on their journey to a lean, ripped physique.
Consequently, Clen is seldom used when athletes are in their bulking up phase, though there are reported exceptions.
The idea behind using Clen during the bulking up phase is to leverage the purported fat loss properties of Clen to help manage the fat gain when individuals are engaging in a high-calorie intake.
This is not a common practice. Clen is predominantly used when individuals want to cut down or are leaning out, as the body goes to a hypocaloric state while cutting fat.
This is felt to lead to improved metabolism and quicker fat burning. In such cases, Clen is hailed as a highly effective way to melt fat fast.
When it is used during the bulking up phases, the results are generally considered to be disappointing and negligible.
The standard dosages of Clen are measured in mcg, or micrograms, rather than the typically used milligram or mg, which is the case for other performance-enhancing drugs.
The difference in dosage and measurement in the case of Clen is thought to be very important in terms of safety and results. When users are not aware of the change in measurement, there is a chance that they might mistake it for mg and it could lead to dangerous results.
Every person who uses Clen will require a specific amount that is determined by their level of need based on their physical makeup.
Men and women function differently metabolically and will need varying amounts according to how active they are or how severe their upper respiratory condition is at the time.
Clen is designed to be used in cycles. Small dosages are given at first and gradually increased until a specific, maintenance amount is reached.
Once maintenance is achieved, it will remain in place until the doctor believes the client’s goals have been accomplished.
After the main portion of the treatment plan is completed, the person’s dosage will be gradually decreased until the drug can be safely stopped without any unwarranted or undesired side effects.
As long as the Clen only cycle is properly observed, the person using the drug should be able to receive the maximum benefits from the drug without any adverse effects.
Some cycles involve using a 2-week on/2-week off cycle. It is important to remember that exceeding 200 mcg can be harmful to your physical health.
Also, while taking this product on its own may be effective for some people, it is most commonly used in a stack.
Some examples of ingredients that you could combine with your dosage include Growth hormone-releasing peptide 6 (GHRP-6), Ketotifen, the steroid Masteron, Primobolan, and SARMS-like Andarine or Cardarine, Omnadren, Sustanon, Nolvadex or Clomid.
You should always take Clen on an empty stomach early in the day and drink a large amount of water with it. Because it can use up the potassium and taurine in the blood, if you feel cramps you should use it with these supplements.
Doses will remain active in your body for up to 24 hours after taking it, which makes this one of the most potent fat loss agents available. This is why you should not take multiple dosages in a 24-hour period.
How To Use Two Week Clen Cycle
This cycle starts at a low dose and you increase the dosage every day for two weeks.
Week 1Week 2Day 1: 20 mcgDay 8: 120 mcgDay 2: 40 mcgDay 9: 100 mcgDay 3: 60 mcgDay 10: 80 mcgDay 4: 80 mcgDay 11: 60 mcgDay 5: 100 mcgDay 12: 40 mcgDay 6: 120 mcgDay 13: 20 mcgDay 7: 140 mcgDay 14: 20 mcg
Remember that Clen HCL will be most effective when used in a stack with other complementary fat-burning substances or ingredients.
Some popular stacks with “Bute” include HGH, Yohimbine, Testosterone, Cytomel T3, and Ketotifen. In particular, Ketotifen inhibits one of the mechanisms that causes many people to develop a tolerance to Clen.
Sometimes bodybuilders stack Taurine and Potassium together with the Clen dosage cycle to offset some of the side effects.
PCTs with drugs like Nolvadex and Tamoxifen are usually not necessary with Clenbuterol.
Why Use Clen HCL?
People who use dosages of Clen for bronchodilator properties do so because it increases the aerobic capacity and acts as a stimulant.
It opens the airways and bronchial tubes in the lungs allowing more oxygen to be utilized and relieving inflammation that prevents a person from breathing normally.
The normal dosage for patients using Clen to control upper respiratory and asthma disorders is 40 mcg per day.
While this can be adjusted as needed, most doctors revert to this as being the standard measure for the medication.
Adverse Clenbuterol Side Effects
Cardiac hypertrophy is possible in people who overuse Clen dosage cycle.
Cardiac hypertrophy is characterized by enlarged ventricles and excessive amounts of stress on the heart.
During hypertrophy, the heart is under extreme pressure to function at a level that is much higher than normal.
Clen dosage cycle can cause several different side effects.
They will range in degree of severity depending on the amount of medication that is being taken. A few of the side effects include:
- Elevated blood pressure
- Increased heart rate
- Excessive sweating
- High anxiety or “the jitters”
- Muscle cramps
- Increased appetites
The longer a person uses any drug, the higher the risk of side effects. Overdoses of Clen dosage cycle need to be prevented to avoid serious health dangerous and negative consequences.
It is important to notify your physician and trainer of all side effects you may experience when using any drug or medication.
Although some side effects are manageable, others may be severe enough that the drug should be discontinued indefinitely. It is important to follow the doctor’s instructions.
Taking amounts that are higher than normal can lead to significant health problems that can lead to conditions like cardiac hypertrophy, palpitations, or irregular heartbeat.
Effects of Clen on sperm count
Abuse of the Clen dosage cycle can cause infertility in men. Sexual dysfunction and a reduction of sperm count are also possible if Clenbuterol is abused or is of a low grade.
When Clenbuterol HCL is administered in the blood it reaches the beta-2 receptors in the blood and reacts with them; causing an increase in the metabolic rate of the anatomy.
As such, the temperature of the body also rises, which may kill sperm cells and lower sperm count.
However, there is no conclusive, empirical data that has linked Clenbuterol use to lowered sperm count, although side effects such as a yellowish tinge of ejaculatory fluid have been reported by some bodybuilders.
Women are more vulnerable to alterations in their hormonal makeup, which can be affected by accelerating their metabolism.
Also, people with very high BMIs of greater than 35 (clinically obese), should not use this drug as it may cause unsafe changes to heart function.
While there can be benefits to taking Clenbuterol pills, it is important that clen dosage cycled safely to ensure a positive outcome for the user.
Clen Dosage Cycle Results
Clen dosage cycles are proven to open bronchial airways and improve breathing when a person is experiencing an asthma attack or other upper respiratory condition.
Its ability to dilate airways and increase the amount of oxygen taken in by the lungs reduces stress and enables the person to breathe much easier.
Clen has also shown benefits as a weight-loss supplement, causing a breakdown of adipose tissue particularly in the mid-section of the body.
It works as both a thermogenic and anti-catabolic helping the body burn extra calories and increase the amount of oxygen used by the muscles during exercise.
When more oxygen is used, fat and calories are burned at a much faster, more efficient rate. This results in a more sustained level of weight loss. As long as the Clen is being used, the weight loss will continue.
When the desired weight is achieved, the Clen dosage cycle will be ceased and the person will begin to maintain their weight loss and keep the weight off.
According to the cycle, the Clen dosage cycle will gradually be reduced, allowing the body to become accustomed to maintaining a specific weight without the need for the drug.
Is Clenbuterol Legal to Buy?
There are many in the US who mistakenly believe that Clenbuterol is illegal to buy. In fact, this drug is not a controlled substance currently in the United States.
In this way, Clen dosage cycle is different from other anabolic steroids such as Dianabol, Deca Durabolin, or Anavar. This means that possession of the drug is not illegal and you cannot be prosecuted for buying it
However, it has been banned by the FDA in drugs and supplements intended for human use. That means there are few legitimate ways to get your hands on it, and you’ll be forced to look to the black market and underground labs to buy it.
Foreign manufacturers in Thailand and other countries have cropped up to meet the demand, but the ever-present danger is fake low-quality products.
Why is Clenbuterol banned?
Clenbuterol is banned because of health concerns and consumer safety.
The only legitimate and legal reason to purchase Clen is for veterinarians to treat asthma and other breathing problems in cows and other livestock, but even this is not legal in the US anymore.
Typically, liquid clen or clen gel formulations are used for these purposes.
These types of Clenbuterol products are not safe for humans. They are not made to pharmaceutical grade standards and oftentimes contain dosages that are significantly higher than a typical 20 mcg pill would contain.
For this reason, even though it is technically legal to buy Clenbuterol online in the USA, most users will not be able to purchase it in pill or tablet form.
However, there are Clenbuterol supplements (do not contain the drug) such as Clenbutrol that are legal or Clenadrol X, which are safe alternatives for bodybuilders to use in their cutting cycles.
Laws in other countries like Canada, Australia, the UK, Ireland, Italy, and New Zealand may be different as of 2016.
In some countries, this product may be available as an over-the-counter asthma remedy, while in others – such as China and Russia – it requires a prescription to purchase it legitimately.
It is important to determine the legal status of this product before you decide to purchase it online or have it shipped to where you live from another country. Clen Dosage Cycles laws in Asia and the Middle East will differ markedly from the USA, for example.
Some of the most common brands of Clenbuterol HCL include:
- Mucosolvan Compositum
- Sekretovit Ex
- Clenox Malay Tiger
- Brogal Compositum
- Clenbuterol hydrochloride tablets
- Ciccone Clenbuterol HCL 40 mcg
Less common brands of Clenbuterol tablets include:
- Ambromuco Compositum
- Clenotabs by Phoenix Pharmachem
- Clen Max 40mcg
- Spiropent Mite
- British Dragon
- British Dispensary
- Broxofar Compuesto
- Mucosolvon Compositum
- Genitec Pharm Clenbuterol
- Venti Plus
- Septacin Ex
- Thaiger Pharma Airclen
There are also hybrid blend products on the market, such as Icyplex which combines bark extract from the Yohimbe tree with Clen cycle.
Ambroxol Clenbuterol combines Clen with another drug that aids in the secretion of mucus from the lungs.
Who Has Used Best Clen Dosage Cycle?
There have been a number of high-profile stories in the news of celebrities and professional athletes abusing and taking advantage of the Clenbuterol benefits for fat loss.
Because it is a sympathomimetic amine, it can have significant enhancement effects on athletic performance abilities.
For this reason, it has been banned by a number of sports and athletics organizations including the IOC, WADA, NCAA, the NHL, the IOC, the MLB, and the AFL.
Clen Dosage Cycles has been used by New York Mets pitcher Guillermo Mota, American swimmer Jessica Hardy, Spanish cyclist Alberto Contador, Toronto Maple Leaf’s hockey player Carter Ashton and many more.
Recently, two players in the Australian Football League that play for Collingwood were found to have used this drug and they are currently awaiting a ruling.
Previously, the Mexican football team was found to have tested positive for the drug. They claimed that this was due to unintentionally eating meat that had been contaminated by the ingredient.
Celebrities also Clenbuterol pills for weight loss cycles, and they can be taken by men or women.
But the bottom line is that due to the risk of potential consequences to your health, it is recommended only to use this belly fat burner if you have a legitimate prescription for it and are using it according to your doctor’s recommendations.
Clenbuterol has a half-life of 36-48 hours and peak plasma concentrations are achieved 2-4 hours after dosing.
It is the key ingredient in other products like Clenbuterol.
It’s commonly misspelled on the internet as Klen 60, Clenbunal, Clean Petrol, Clean Patrol, Cleanbuterol, Clembuterol HCL, Clenbutorol, Clenbutanol, Clenbuteral, Klenbuterol, Clebuterol, Clenbuter, Clenbut, Clenbetrol, Klen buterol, and Cleanbutrol.
If you want the best clen dosage cycle, there are safe, legal supplement formulations that you can buy instead to give you the same effective results for your cutting cycle. Regardless of what you take to help you lose weight, you need to be on a low-calorie diet to see results. Some say a low-fat diet, while others claim you should limit carbs.
