In this guide, you’ll learn:

Clenbuterol is a drug that speeds up your metabolism and helps you burn fat. Some athletes and wrestlers take clenbuterol to help them reach their exercise goals.‌

Before a show or competition, clenbuterol is often used by bodybuilders to get rid of extra layer of fat. One of the side effects of this drug is that it makes you feel less hungry, so you eat less.

But here’s the thing. Clenbuterol is a common way for bodybuilders and athletes to lose weight when they don’t want to use anabolic drugs. It’s kind of like a stand-in that does the job. But you need to know how to use it well. You shouldn’t get started on it right away. You should know what it can do to your body before you start to use it.

Here’s what you should know about this strong drug.


Clenbuterol is a sympathomimetic amine that helps people with breathing problems clear their airways and open up their airways. People with long-term lung problems like asthma use this to make it easier to breathe. It is most often sold as clenbuterol hydrochloride, which is the salt of clenbuterol and chloride.

Clenbuterol, on the other hand, is a famous Anabolic Steroid used by lifters. It changes everything when it comes to losing weight. This stuff works by making your blood vessels tighter, which helps to clear up congestion and relaxes the smooth muscle tissue in your lungs.

It makes it easier to breathe, so you can keep going during those hard workouts without gasping for air.


People can use clenbuterol to help them lose weight because it can make their body work faster. It has been seen to both build more muscle and cut down on body fat. In addition to lowering body fat and weight, it also helps the person keep muscle bulk and body power.

Clenbuterol is meant to be used when all other weight loss plans have failed. Think of it as the big finish or the cherry on top. And keep in mind that it’s not a long-term fix. You can only use it for a limited amount of time, so make every turn count and watch the pounds melt away.

This powerful fat burner raises your metabolic rate by increasing thermogenesis. It is more of a stimulant than a steroid. Due to this, it burns off fat even when you are at rest. Clenbuterol is an effective fat burner that helps you lose weight fast.

Clenbuterol And Bodybuilding

Taking this kind of medication feels like you’re on steroids. That is because it’s an agonist of beta-2-adrenergic receptors in your body. It relaxes your muscles and lungs. So, if you’ve got asthma or breathing problems, this is a good choice for you. The effect lasts 39 hours.

As a bronchodilator, Clenbuterol opens up your airways so you can get better airflow. It’s good for people who suffer from asthma, but it can also improve endurance in athletes. This enables them to perform longer and harder as there is more oxygen to work with. ‌

One cannot deny Clenbuterol’s weight loss potential. Whether you’re a fitness fanatic or a bodybuilder – popularity is the same.


It’s well known as one of the best fat burners around, so we know that’s its strongest suit. But what exactly does that mean? And why does Clenbuterol work so well at burning off the fat you’ve been trying to lose for a long time?

These are the main benefits and effects of Clenbuterol:


This is why clenbuterol is popular with bodybuilders before competitions or performances. It’s also a secondary effect because it curbs your appetite. You don’t get this effect for everyone, though.


Clenbuterol’s main function is to raise your body temperature to burn fat. A human body needs thermogenesis to stay alive. It has a direct effect on the metabolism. When it’s increased, the metabolic rate rises due to increased body temperature. This results in fat breaking down faster and more.

Taking Clenbuterol has been shown to help you lose weight. It raises your metabolism so that you burn off fat. One study put two overweight men on a strict diet for ten weeks. The group that got clenbuterol lost 11.4 kilograms of fat. And the control group lost 8.7 kilograms of fat.


Clenbuterol doesn’t have a big impact on this area. But even a slight increase is welcome to most people. Since Clenbuterol is primarily used to open the airways for breathing, it makes sense that even people who don’t have breathing issues can enjoy it. But, it’s important not to expect a noticeable change in this department. So, if you’re after hardcore performance enhancement, Clenbuterol does not fit the bill. But this potentially small benefit can be thought of as a bonus.


Clenbuterol is great for getting rid of stubborn fat on a lean body. And is thus popular with physique competitors and athletic models. And anyone who already works hard to get ripped and lean, and wants to go even further.

Or, Clenbuterol isn’t that useful or necessary for someone who’s obese. And it’s best to lose as much weight as possible before using it.


Weight Loss And Clenbuterol

It burns fat fast, which is why athletes and bodybuilders use it. It burns fat but also builds muscle. Athletes usually take between 60 and 120 milligrams a day. And they usually combine it with anabolic steroids.‌

If you take Clenbuterol, your body temperature can go up. Once your body temperature rises, your metabolism gets primed to burn more calories. As a result, you will lose weight and fat. Fat is stored in your body as energy, so you can use your existing calories.‌


Bodybuilders should take it in the morning for the best results. Clenbuterol is only a suitable steroid alternative during the hotter months.


You can use this Clenbuterol cycle example just about anywhere. This cycle is two weeks on, two weeks off. For two weeks, Clenbuterol is taken every day, then stopped for two weeks, then restarted. The dosage values are listed below.

  • The first two days: 20mcg
  • The third and fourth days: 40mcg
  • On days 5 and 6, take 60mcg
  • For days 7-8: 80mcg
  • On days 9 and 10, take 100mcg
  • The 11th and 12th: 120mcg
  • The 13th and 14th: 140mcg

At this point, when the dosage has reached its peak at 140mcg, the cycle is stopped. You get a two-week break and then start again. You don’t start at the low level, but rather at 140mcg, as you did during your last cycle. During the second cycle, this dosage is kept the whole time.


Clenbuterol is perfect for fat loss when used as a standalone supplement. But how about for bodybuilders as a part of a cutting cycle?

Using Anavar in this cutting cycle will compound the effects of Clenbuterol. The above cutting cycle is suitable only for experienced users. If you don’t know how to deal with the side effects of anabolic steroids you should consult with a physician first.


We’re talking about an advanced 8-week Clenbuterol cycle here:

  • Taking 100mg of testosterone a week (25mg every other day)
  • Take 200 mg a week (50 mg a day) of Tren Acetate
  • A Masteron dose of 400mg/week (100mg/every other day)
  • Take 90mcg of T3 a day
  • For weeks 1-2, 5-6, and 8+: 120mcg of Clenbuterol


A lot of athletes and lifters swear by clenbuterol. It’s like their secret weapon. It helps them perform better and get those gains.

But listen up; there’s a catch. This stuff can come with some risky side effects.

If you go all crazy and start popping big doses of clenbuterol to shed those pounds, you’re just asking for trouble. Those side effects can hit you hard, especially if you’ve never messed with clenbuterol before. First-time users are more susceptible to the side effects.

And here’s something you’ve got to know: Clenbuterol likes to stick around in your system for a while. So, those side effects? They might not show up right away.

They can hit you anywhere from one to eight days later.

Studies have shown that over 80% of people who went overboard with clenbuterol and had major side effects had to rush to the hospital.

If you’re using clenbuterol and start experiencing any of those gnarly side effects, don’t mess around. Stop using it right away and go see a doctor. Your health ain’t worth risking.

Some of the most common side effects include:

  • Anxiety
  • Agitation
  • Sweating
  • Increased heart rate (tachycardia)
  • Cardiac arrest
  • Feeling excessive hot or warm
  • Muscle cramps
  • Heart palpitations
  • Tremors
  • Insomnia
  • High blood sugar (hyperglycemia)
  • Lowered blood potassium (hypokalemia)


Clenbuterol is a powerful compound that can have significant effects on your body.

Most patients with clenbuterol toxicity can be managed with supportive therapy, including IV fluids, potassium supplementation, and benzodiazepines for agitation. However, in some cases, more aggressive treatment may be necessary.

Post-cycle therapy (PCT) is a treatment regimen that is used to restore natural testosterone levels after a cycle of anabolic steroids. Clenbuterol is not an anabolic steroid, so PCT is not necessary after a clenbuterol cycle.

If you are considering using clenbuterol, it is important to talk to your doctor about the risks and benefits. Clenbuterol can be a safe and effective way to improve your athletic performance, but it is important to use it responsibly.

Can you use Clen steroid to lose fat?

While clenbuterol has been shown to increase metabolism and promote fat loss, it is important to note that it is a powerful drug with potentially dangerous side effects.

Here are some of the ways that clenbuterol can promote fat loss and increase metabolism:

  • Increases thermogenesis: Thermogenesis is the process by which the body generates heat. Clenbuterol can increase thermogenesis by uncoupling the process of ATP synthesis from muscle contractions. This means that the body produces more heat without actually producing more energy.
  • Increases lipolysis: Lipolysis is the breakdown of fat into fatty acids. Clenbuterol can increase lipolysis by activating beta-2 adrenergic receptors on fat cells. These receptors signal the fat cells to release fatty acids into the bloodstream.
  • Increases energy expenditure: Clenbuterol can increase energy expenditure by increasing heart rate, respiratory rate, and muscle activity. This can help to burn more calories both at rest and during exercise.

It is not approved for weight loss by the FDA, and its use for this purpose is considered to be off-label. If you are considering using clenbuterol for fat loss, it is important to talk to your doctor about the risks and benefits.
