Popular in both the athletic and bodybuilding arenas as a very potent supplement, Clenbuterol, or “Clen”, isn’t actually a steroid or a hormone. Much like the commonly prescribed albuterol, Clen is a bronchodilator in nature, meaning its primary use is to treat asthma and similar respiratory complexities.
The supplement is actually commonly used by veterinarians to treat horses and other animals for congestion issues. It is also given to cattle to help them to burn fat, hence it is sometimes found in meat in trace levels.
However, athletes and bodybuilders use it for its secondary benefits namely, burning fat and boosting energy. While it’s not currently approved for human consumption by the FDA, Clenbuterol can be found in many popular pharmaceuticals in other countries and sometimes even sought after by Hollywood celebrities.
It sometimes goes by the names of Ventipulmin, Bute, Spiropent or Dilaterol and it was banned from the Olympic in the 1990s.
If you have been looking to find Clenbuterol online, you’ve probably had a tough and confusing search. Legitimate high-quality pharma grade Clenbuterol is hard to find and riddled with potential legal issues, side effects and raises concerns over quality.
But there is a solution…
Nowadays, we have safe and legal Clenbuterol for sale from Crazy Bulk. The testimonials speak for themselves…
Our Recommended Clenbuterol…
What Is Clenbuterol?
As mentioned earlier, the primary purpose of Clen (Clenbuterol hydrochloride) is to act as a bronchodilator and for that reason, is often prescribed as a treatment for asthma, chronic obstructive pulmonary disease (COPD) and similar conditions by physicians in many countries outside the U.S. Mainly; it relaxes the airway muscles, making it easier for its user to breathe by:
- Thinning the blood, reducing blood pressure
- Widening the blood vessels that transport oxygen.
By being a sympathomimetic and stimulating the heart and central nervous system, Clen makes the body produce more adrenaline and epinephrine, enhances the secretion of thyroid hormones as well as increasing peristalsis. this reduces the time required for food to be absorbed and stored.
But athletes and bodybuilders around the world don’t purchase it for its medicinal purposes but rather for its weight loss and thermogenic properties. Bodybuilders who have completed a bulking phase (often in a testosterone boosted steroid cycle) will want to go into cutting cycles (usually to get ripped for a competition). Using a Clenbuterol cycle as part of this cutting phase increases the user’s metabolism and they can benefit greatly from Clen if they have experience in (or experiencing) anabolic steroids or natural steroids. This is done by causing thermogenesis which raises the body’s core temperature which in turn will increase the body metabolic rate. This makes it the best weight loss fat burner on the market,
Fat Burning Function
But to understand Clen’s functions properly, we have to get a bit more technical. Clenbuterol actually belongs to the sympathomimetic drugs class. And like the other contributors of its class, the pharmaceutical is a receptor agonist that stimulates the beta-2 adrenoceptors to effect sustainable improvement in relaxing the airway and overall breathing.
In addition, as a secondary and complementary function, it also improves the consumer’s metabolic system meaning, it improves their energy production rate by burning stored fat (calories). But keep in mind that Clen does not actually burn fat but facilitates the process by increasing your core body temperature. This is what improving metabolism refers to.
The affected beta-2 receptors stimulate the mitochondria of every cell of the body and slightly raise the overall body temperature. Coupled with the now improved metabolism, this leads to lipolysis and stored calories burn much faster.
The effects are:
- Fat burning
- Boost in energy & mental activation
- Appetite decrease
Is It An Anabolic Steroid?
This is a very common question when it comes to clen which starts many discussions in the steroids and science community. Some refer to it as Clen steroid. It actually has a similar structure to salbutamol and epinephrine as it is a β2 agonist. It is often mentioned online with bodybuild steroids as it is used by bodybuilders. But it stimulant and is part of the group which contained Adderal, Caffeine and Ephedrine.
Clenbuterol functions via the adrenoreceptors located throughout the body which stimulates the sympathomimetic central nervous system. This stimulates the blood pressure and aerobic capacity. It also causes the desired effect which is thermogenesis and to increase metabolic rate.
For these reasons, we can conclude that Clenbuterol is not an anabolic steroid. There are side effects that greatly depend on the sensitivity of the user, as well as the quality and purity of the products. As we will discuss later, these include insomnia, an increased heart rate, tremors, muscle cramps and breathing difficulties.
There is an idea that it offers anabolic effects, similar to steroids. According to a study on the skeletal muscle tissue in rats, Clenbuterol showed a small amount of anabolic effect when used for an extended period. Although there was some effect on muscle tissue, the researched claim that this level of dose would be dangerous to be taken by humans. So at safe dosage amounts for humans, it should not have an anabolic effect. However, there have still been bodybuilders who claim that they have received some minor anabolic effects along with improved physical performance.
How Does It Work For Bodybuilding?
The following results are from Crazy Bulk Clenbuterol:
Clen inhibits lipoprotein lipase activity, making the deposition of fat cells very difficult for the body. Also, by enhancing the thyroid gland hormones, the fat burning effect is increased. The thermogenic effect of the drug means that the internal temperature of the body is increased slightly and calorie consumption increases. Scientific studies suggest that a 1-degree increase means a 5% increase in calorie burn.
While anabolic properties have been noted in research on animals, studies show that it is unlikely in humans due to the low amount of beta-3 receptors and the sensitivity to insulin. Clenbuterol is dosed in micrograms and mainly found in pill or tablet form. It can also come in nasal sprays, oral solutions or injectable liquid form. The liquid Clenbuterol can be taken orally or injected to help with those who have digestion issues. However, these are often produced by underground laboratories.
Many manufacturers will display the volume of ingredients in milligrams. A 0.04 dose will be shown as a 40 μg tablet
There is a misconception due to Clenbuterol’s anabolic properties, however. Many online sources believe that logically, Clen should help in producing “bulking” results in addition to cutting. But that doesn’t happen. Laboratory tests show that while it does help rats in developing some lean muscle tissue, humans show no such effects whatsoever. So regardless of expectations, Clenbuterol has two functions: treat respiratory conditions and burn fat. Excluding unforeseen, unique and unrecorded phenomena, there’s nothing else to be expected from its usage.
Who Uses It?
Clen is used by bodybuilders who want to get ripped before a competition or models who want to lose the last bit of stubborn fat before a photoshoot. Clenbuterol is certainly one of the best weight loss supplements on the market when it comes to rapid results for body-fat reductions. It is sometimes considered Hollywood’s secret fat loss drug due to the number of celebrities and professional athletes that use it. It is often used by bodybuilders after cycles of steroid medications. Be sure to read our guide on Dianabol for sale for more information Dbol and other steroids.
But this should be taken lightly. The information available should still be taken seriously by anyone that decides to use it. Users of it should drink plenty of water, eat healthily, exercise and sleep properly. They should always remember that it will not instantly drop excess fat. It still takes time but it will supercharge anyone’s weight loss and also performance results come quicker. It is worth noting that bodybuilders will sometimes stack Clen with steroids to boost protein synthesis.
Clenbuterol Dosage For Men and Women
In countries other than the U.S., when it comes to medicinal purposes, the daily consumption rate usually ranges between .02 mg/20mcg and .04 mg/ 40mcg. However, when it comes to performance enhancement issues, the daily rate pushes way past the general maximum. In fact, 40mcg is the standard starter dose. But since the supplement affects men and women differently and since women are more sensitive to it, it’s better for them to start out at 20 mcg.
Maximum plasma concentrations peak at around 2-3 hours following oral administration with a 36-hour half-life (Zimmer, 1978). The maximum daily dose is 140 mcg. Anything over this only causes supersaturation of receptors, deeming it useless.
One point of importance is the rapidity at which a user’s body becomes adapted to Clenbuterol. This is why it is not advisable to take clenbuterol for extended periods without any sort of break. To counteract this enhanced rate, a user needs to compound on their starter dose on a daily basis at a fixed amount. But the adaptation and tolerance rate varies from individual to individual, making it almost impossible to produce a flawless standard.
Clenbuterol Cycle For Weight Loss
Once a clenbuterol cycle is started on the beginner’s dose, it can either be used:
- In Rotation
Regardless of its efficiency, Clenbuterol does have some side effects, which we shall consider in detail later on. But to get the desired effect quickly, its continuous usage, without any on-off cycles, is the best policy. It’s also the best alternative when individual tolerance is added into the equation. Due to potential side effects, however, you have to be careful with the incremental dosage and learn how the body tolerates the drug.
Begin at the aforementioned level (40 mcg or 20 mcg) and keep to that rate for two complete weeks. From the fifteenth day onward, increase the rate by 20 mcg every day and continue that routine for another couple of weeks. Continue the same process and rate from the twenty-ninth day onward for another two weeks. If this is part of your diet then continue until that dietary plan ends. However, the daily rate cannot, under any circumstances, surpass the maximum limit of 120 mcg.
While the continuous usage system provides an around the clock boost to your metabolism and thereby maximizing the intended weight loss process, it also increases the probability for potential side effects. Prolonged continuation and extreme daily rate naturally add to that probability.
Basically, the continuous method can be charted as follow:
- Week 1-2: 40 mcg/.04 mg per day
- Week 3-4: Start at 60 mcg/.06 mg and add 20 mcg/.02 mg each day without surpassing 100 mcg/.1 mg
- Week 5-6: Start at 100 mcg/ .1 mg and keep within 120 mcg/.12 mg
Clen Cycle In Rotation
The other alternative, which is in fact preferred by bodybuilders, is to use clenbuterol in rotation. It means the supplement is effected into your system through a predetermined set of on-off cycles. This is thought to maintain the receptivity of receptors. This set is usually made of two weeks on and two weeks off cycles. The rotative method gives better flexible control over monitoring body fat percentage compared to the continuous system.
To utilize this method, start at the beginner’s dose (40 or 20 mcg) and keep at it for 3/4 days. After that, increase the rate by another 20 mcg and keep doing the same thing after every 3/4 days. The whole process should be contained within 2 weeks and again, must not surpass the maximum limit of 120 mcg. Once the first two on weeks are done, follow it with a two weeks’ off cycle. You have to stay completely clean of Clenbuterol during the off weeks. After that, begin the whole process anew. The rotation method is great for reducing your tolerance level, making your body less prone to Clen adaptation.
The rotation method can be charted as follows:
- First 3 days: 40 mcg/.04 mg per day
- Day 4-14 (Second weekends): Compound by 20 mcg/.04 mg after every 3/4 days and keep within 120 mcg/ .12 mg
- Day 15-29 (Next two weeks): Off
No matter which method you choose to follow, continuous or rotation, your maximum daily doses must never surpass the absolute 120 mcg under any circumstances. Another thing to consider is how often you can actually use it. The maximum limit is 16 weeks out of the 52 of a year. It’s up to your preference, how you wish to follow through these weeks: continue the Clenbuterol cycle for straight 16 weeks or break it down to 4-week cycles.
During the break from the Clenbuterol product, some users switch to ECA (a mixture of ephedrine, caffeine, and aspirin). ECA does not create such desensitization and depression of receptors in the way the Clenbuterol does. Ephedrine has a shorter half-life giving receptors a chance to recover after norepinephrine and epinephrine stimulation. It is understood that ephedrine activates the enzyme monodeiodinase which accelerates the conversion of exogenous and endogenous thyroxin to triiodothyronine. Many bodybuilders will take triiodothyronine concomitantly with Clen or ECA to maintain normal levels in the blood.
Women usually take lower doses of Clen than men. However, some people use it all year round, albeit at a very low dosage rate (20/40/60 mcg). The purpose is to maintain the current body fat rather than to lose weight. However, it’s a matter of personal preference and completely depends on your own weight, risk measurement and goal.
There is a common misconception, which is often strengthened by personal experience, concerning regular usage of Clenbuterol products that over time, your systems become completely adapted to it and nullifies the supplement’s effects. This is a baseless assumption.
Clenbuterol is a stimulant. So when you use it for the first time, your systems experience new stimulation that leaves you feeling observably energetic and focused. This effect is comparable to that of caffeine. However, after some time, the user stops feeling like this leading to the false assumption that Clen has stopped working.
True, you need all the energy you can muster in athletic and bodybuilding endeavors but don’t forget the actual purpose of Clenbuterol: its thermogenic character makes your body more effective at burning fat cells.
The fluctuating rate and cycles discussed before are purposed to throw your tolerance level off track, which allows you to sustain the stimulation for longer. But even if you don’t and your body becomes accustomed to the “first time” effects, it’d still take in the thermogenic, fat-burning properties without you noticing.
Clenbuterol Side Effects & Dangers
As mentioned earlier, Clen does have some actual side effects and when it comes to severity, these wildly range from mild to extreme. Fortunately, the more common effects subside quickly but if a user does not know what they are doing, the results can be disastrous as clenbuterol is still a toxic fat burning drug. It’s important for anyone to observe the reactions of their body to any drug.
The most common side effects of Clenbuterol are:
- Increased body temperature
- Shaking & muscle tremors (particularly hand tremors)
- Irregular and increased sweating
- Heart palpitations
- Subaortic stenosis
- Cardiac hypertrophy
- High blood pressure
- Electrolyte imbalance (reduces potassium levels)
- In animals, necrosis of heart tissue was found
In effect, it sounds much like those of amphetamines such as ephedrine which is also sometimes used by bodybuilders. While the shaking and sweating are both common, in some individuals, they turned out to be incurable unless they gave up Clen completely.
The anxiety and restlessness could often lead to complete sleeplessness or insomnia and can only be remedied by using some sleep aid like diphenhydramine. But for them to take effect, you have to ingest Clenbuterol right after you wake up in the morning, since it has a long half-life of 36 to 48 hours. So break up doses into smaller ones taken throughout the day in order to lower the manifestation of side effects.
There are more severe side effects, which are often cardiac in nature. These include high blood pressure and the increased blood circulation rate coupled with dilation could work as the preconditions for potential cardiac hypertrophy. This is a condition where the heart, to support the increased blood rate, grows abnormally in size.
So if you already have a heart condition or increased blood pressure, then it is highly recommended that you don’t try to buy Clenbuterol online.
It is not recommended that anyone with hypertension or cardiac disorders use clenbuterol either. There is insufficient research on the cardiological effects of increased doses in humans.
Due to their strict training and workout sessions, bodybuilders usually have larger than average hearts. If they have to accommodate for the hypertrophy effect, the result could be highly dangerous. This could potentially lead to heart attack and hence, the supplement has been banned by the International Olympic Committee (IOC) as a usable substance by athletes.
Keep in mind that these effects occur either temporarily or due to prolonged usage at a high rate. Many adverse reactions reduce with a more prolonged admission of the drug. It is also important that caution is taken when it is used alongside other adrenoreceptor agonists as the side effects may be exacerbated. Risk assessment is thus mandatory when Clen is taken into consideration.
Clenbuterol Legal Status
Clenbuterol is banned for use by IOC tested athletes and it is not approved for human consumption by the Food and Drug Administration in the United States. It can legally be used on animals in the USA. Clenbuterol is often used on humans in other parts of the world such as Russia and China where it can be prescribed for the treatment of asthma due to it’s strong bronchodilator effects.
There have been cases of food contamination where traces of clen were found in athletes during testing. This was found to be due to farmers giving clenbuterol to cattle to enhance the leanness of the meat which was then consumed by athletes.
How To Deal With Muscle Cramps?
Muscle cramps are one of the most common side effects of clenbuterol. They likely take place due to a deficiency of potassium and sodium, insufficient hydration and taurine depletion in the liver. Research suggests that taurine, when used as an additive, reduces muscle cramps. This is due to its strengthening of cell membranes and preventing overexcitement of the central nervous system. Some solutions to this are:
- Increase Taurine intake – 3+ grams a day
- Eat more fruit (bananas in particular)
- Drink more water
- Use potassium supplements (on an empty stomach)
It does not build fall into the classification of an androgenic or anabolic steroid like Dianabol, Anavar, Winstrol, Deca Durabolin or Trenbolone does. So do not expect growth in muscle mass or strength and endurance. But it is a very good and powerful fat burner with anti-catabolic effects.
Clenbuterol burns fat by stimulating the central nervous system. This causes a rise in body temperature and an increase in metabolism to burn fat quicker than normal.
Yes, clenbuterol will burn belly fat. But it will also burn fat across the entire body. It is not possible to reduce fat in one area of the body naturally.
Clen is not approved for human use by the US Food and Drug Administration. Clenbuterol is also banned by the International Olympics Committee. It can be legally administered by veterinarians to horses.
Conclusion – Where To Buy Clen?
We recommend Clenbuterol by Crazy Bulk
Considering all the possibilities and facts, concerning both misconceptions and risks, if you choose to use a Clenbuterol product, always keep in mind that this is not a miracle weight-loss pill. It won’t work unless you supply it with basic weight loss methods namely, diet and exercise. Clen enhances each cell’s ability to utilize calories but not to the point where you could sit back and relax and let it take over. Eat properly and workout and let Clen help you out, very effectively, along the way.
