Clenbuterol is one of the most successful fat burners in today’s bodybuilding and fitness industry, and as such it’s widely used by both men and women. Clenbuterol is a bronchodilator used for treating asthma, but its thermogenic nature is what’s made it so popular for fat loss. And with the right dosage, it can be incredibly effective. Every individual is different, however, and therefore has different toleration for stimulants, which basically means that some people will get better or worse results, especially if they don’t plan an appropriate dosage for Clenbuterol.

The most important part about Clenbuterol is perfecting the optimal dosage, because if you take too little you will only waste the product and money, and thus gain no effects at all, on the other hand if you use it with much higher doses than prescribed you will have great results but with a possibility of side effects.

Initial Clenbuterol Dosage

Before we start to talk about the starting dosage for Clenbuterol, it’s important to keep in mind that dosages of Clenbuterol are measured in micrograms (mcg), and not the more common milligram (mg) measurement. It is important to note this distinction to ensure you get the maximum dosage and also to keep the risk of potential side effects to a minimum.

Clenbuterol is typically available in 20mcg tablets, although 40mcg, 50 mcg and 100mcg tablets may also be found.

When it comes to Clenbuterol dosage one should ease in with a smaller starting dosage, 40mcg for men and 20mcg for women. In time, the body will adapt to these doses, and they should be increased if the fat losing effects are still to be enjoyed. This makes it even wiser to start off with a smaller dose, because if you start off with a higher dose, you will reach your maximum dosage quickly which can increase the possibility for side effects.

Increasing the Clenbuterol dose

The longer you take Clenbuterol, the doses will need to increase to have maximum effects. The wisest method  is to do a slowly and steady cycle. The body will adapt to Clenbuterol at a fast pace, where some individuals can over exaggerate, thinking that the efficacy of Clenbuterol is not there, while their body is successfully burning fat. Clenbuterol also has a long half-life, approximately 34 hours, meaning it only needs to be dosed once or twice a day.

When Clenbuterol usage begins, most individuals will feel a little wired, similar if they would consume a larger quantity of caffeine, but within a week your body will get used to it. Although this wired feeling may have passed, the same Clenbuterol dosage can keep the metabolism amped for 6 weeks, even if it won’t be as strong at this stage, it will still be significantly enhanced. The actual goal is to keep the body fully enhanced, and to achieve this we only need to increase the dosage by 20mcg every 2-3 weeks, but most commonly its 2 weeks.

This example will show this best: after 2-3 weeks of use at 40mcg/day, a man would increase his dose to 60mcg/day, and continue to take this dose for another 2-3 weeks, where a woman would increase her dose from 20mcg/day to 40mcg/day, and also use that dose for another 2-3 weeks.

Th3 most commonly used type of cycling Clenbuterol is 2 weeks on, 2 weeks off. This cycle is the most popular and used for many reasons, but most importantly because it’s proven to be consistently effective and successful when it comes to fat burning. Its side effect safe, as you can control the maximum dosage, raising it slowly in time.

The fat burning which is caused by Clenbuterol remains in your body for 4-6 weeks, prior to Beta-2 receptors decrease in sensitivity develops and becomes apparent. Some users encounter this in those 2-3 weeks off. But as there are different methods when it comes to usage of enhancing drugs, some people can’t afford to take periodic breaks from Clenbuterol use. They tend to use it in a more rapid and aggressive way, which can be read here.


This is where some tend to use Ketotifen Fumarate, which is a drug used for treating asthma which regulates the Beta-2 receptors, which naturally downregulate when you use Clenbuterol, especially when higher doses are used. The magic around Ketotifen is that it upregulates the beta-2 adrenergic receptors that Clenbuterol stimulates. As long as you take Ketotifen it will continuously upregulate these receptors, prohibiting a loss of sensitivity. Ketotifen can efficiently be utilized by administering it 2mg/day for 7 days, starting every second week when you use Clenbuterol (its best used before bed).

Also to improve fat burning, a lot of individuals use Clenbuterol with Cytomel (T3). Cytomel is a is the most common brand name for a synthetic thyroid hormone, and thyroid hormones are responsible for regulating the metabolism of the body.

High levels of T3 will speed up the metabolism, allowing the body to burn more calories and use calories more efficiently. Those who combine these two compounds will burn an enormous amount of fat. The most common way to use Cytomel is to use it in those 2-3 weeks when you pause from Clenbuterol, which will make your body constantly burn fat, and lose weight. The Cytomel dose should start at 20 mcg/day, for the first 2-3 weeks, and max out at 50 mcg/day, in the later cycle period.


Even if Clenbuterol is not a steroid, but a thermogenic product, it should be classified as delicate in terms of how to properly use it. Clenbuterol should be cycled properly for not only safety reasons and avoidance of short and long term side effects, but that of efficacy as well. With this kept in mind men should not exceed a total dose of 140mcg/day, and women 100mcg/day. When the max dose is reached, it shouldn’t be used for more than 2-3 weeks, for safety reasons. Clenbuterol should not be used for more than 16 weeks per year.


The female reaction to Clenbuterol is exactly the same as for men. The main difference is in body mass between men and women, where women are generally smaller and have less weight than men, and because of that they are more affected by Clenbuterol. This is why women use lower doses with all types of enhancers. This being said the starting dose for women is 20mcg/day, and the max dose should be 100mcg/day, but some tend to go even further, which is not recommended.


The usual way to end a Clenbuterol cycle is to steadily decrease the dose every few days, until the cycle ends. Although this is a popular method, it’s not the most optimal, and provides no real advantage. You shouldn’t either go cold turkey with Clenbuterol, all you need to do is simply gradually ramp down the amount you are taking to the original Clenbuterol dosage you started your cycle with. Most men and women will find that 40mcg/day for 1-2 weeks is optimal, and once this period has passed, discontinue use and end your cycle.

But all this comes out of personal preference of an individual. Some tend to taper down their Clenbuterol dosage, and some tend to halt Clenbuterol use without any tapering of dose. This is all because some individuals have experienced a type of stimulant crush, when choosing to halt Clenbuterol, instead of tapering it.


All medications and drugs of all types carry with them a potential for negative reactions. The same goes for Clenbuterol, where individual’s sensitivity, dosing and purity of the product will determine how great this probability is. Most side effects come from using high doses for a long period of time.

Clenbuterol side effects are by no means life-threatening, but they can be annoying for some individuals. Most users, when they start to use Clenbuterol will find that they are very jittery, feeling wired and having your hands shake, but this feeling only lasts for a while when the drug takes effect upon consuming it. Most users will adapt to this very quickly, within the first two weeks of usage. Another possible side effect is insomnia, which manifests if Clenbuterol is used late in the day. This can be easily avoided by not consuming it after 7-9PM, because the stimulating effect of Clenbuterol will begin to wane many hours after the dosing is applied.

Also worth mentioning, a common side effect is muscle cramps, because Clenbuterol depletes taurine from the body. This can be avoided by staying well hydrated as well as ensuring you have adequate amounts of potassium and sodium in your body. Some even supplement themselves with taurine.

All these side effects mentioned above are easily avoided, and in the end your body will get used to them quickly. But some side effects can be severe, like cardiac hypertrophy, quite simply hearth problems. This can happen if Clenbuterol is used irresponsibly, for a very long time, possibly with high doses (this goes pretty much for any type of drug or steroid).

Most side effects are avoidable with Clenbuterol, but if you keep having some sort of side effect for a long time, and your body just doesn’t get used to it, just lower the dose, or simply stop using it.

    • Hej Olsen,

      Et produkt, der er udløbet siden 2018, vil ikke længere være effektivt. For et bedre resultat og for din sikkerhed, råder vi dig til at købe et nyt produkt som f.eks. Clenbugen.
