Workout aids are available in so many shapes and sizes that it’s almost impossible to know where to start. I’ve taken a lot of supplements to both good and bad results, but there’s one thing you won’t find me advocating: taking a proven, tested, and approved medication without a prescription in order to lose weight or up your gym game.

But that’s exactly what millions of men do on a daily basis to enhance performance, lose weight, and feel better with clenbuterol. I’ve written before about clenbuterol as it’s an incredibly popular fat loss and workout aid beloved by athletes and amateurs worldwide.

However, as a substance not sold legally in the United States or approved by the FDA, I’d always been wary about using it. That is, until I heard about Clenbutrol: a clenbuterol imitation safe for use and sold in the U.S.

I know guys who have gotten great results with clenbuterol, but it’s not something that was really right for me. That said, Clenbutrol seemed like a compelling alternative, boasting the same benefits without the risks.

Here’s what I learned after four weeks of enjoying a substitute for one of the fitness world’s best-loved secrets.

What Is Clenbutrol?

Clenbutrol (, nicknamed Clen just like its prescription big brother, is a fat-burner for men that can help users bulk up and slim down. Clenbutrol is intended to mimic clenbuterol, a prescription bronchodilator and decongestant medication with thermogenic properties.

It was originally invented to address those with pulmonary problems, aiding the process of breathing by simultaneously reducing blood pressure while expanding blood vessels for an increase in oxygenated blood. However, this combination of effects is also desired in another population: fitness lovers and athletes.

In addition to these beneficial functions, clenbuterol also raises the body temperature by increasing cellular activity in the mitochondria, improving calorie burn in the gym and in everyday life. Clenbuterol is used around the world, primarily in Latin America and Europe, for its original purpose.

It is prescribed by physicians for those in need, and carefully regulated. Nevertheless, this is not the case in the United States.

Clenbuterol has never actually been tested or approved by the FDA and is not authorized for human use, likely because other medications are widely available that offer the same benefits. It is also banned by the World Anti-Doping Agency and the International Olympic Committee, making it a poor choice for athletes who may be subject to testing.

For those who want the same benefits as clenbuterol but don’t want to risk an overseas purchase or a potential doping scandal, Clenbutrol offers the same benefits in a natural variation without the serious associated risks.


Clenbutrol is comprised of several key ingredients, which include Garcinia cambogia, guarana extract, vitamin B3, and bitter orange extract.

Clenbutrol Ingredients

Garcinia Cambogia

A tropical fruit regularly found in workout supplements, Garcinia cambogia can limit appetite, stabilize blood sugar levels, increase energy, and reduce sugar cravings.

Guarana Extract

A naturally-derived stimulant, guarana extract is a popular substance in energy drinks. With a caffeine level twice that of coffee beans, guarana beans can keep users alert and awake.

Vitamin B3

One of the essential B vitamins, Vitamin B3, or niacin, can address high cholesterol and triglycerides and is also an effective tool against heart attack and the narrowing of the arteries.

Bitter Orange Extract

A common ingredient in weight loss supplements, bitter orange extract is a natural ingredient that contains synephrine, a substance similar in structure to ephedrine with potent fat burning abilities that is found in clenbuterol itself.

Benefits of Clenbutrol

As a workout aid, clenbutrol has many benefits for users to enjoy. These include:

  • Thermogenic abilities to improve metabolism and encourage fat burn
  • Better performance and strength in the gym
  • Heightened energy and endurance due to improved production of epinephrine and noradrenaline
  • Fat loss that doesn’t affect muscle mass
  • Faster, easier muscle-building
  • Ability to suppress appetite, reducing cravings and binge eating

Clenbutrol Dosage

Clenbuterol, when prescribed by a doctor, is often given in doses of 20 to 40 mcg per day. However, dosages are much easier to manage with Clenbutrol.

As a supplement, Clenbutrol users should take three pills a day, at least 45 minutes before a workout, for best results. Each bottle contains 30 doses, or 90 pills.

Cycling is suggested for some supplements, and Clenbutrol is one of them. Users of Clenbutrol should take doses for two months followed be one and a half weeks off to reset the body.

Do not take more than three pills per day, even after extended use.

Side Effects

Clenbutrol doesn’t come with any of the hazardous consequences that accompany clenbuterol, but may still have side effects, including:

  • Increased heart rate, potentially to unsafe levels
  • Jitters and anxiety lasting the duration of use, similar to drinking too many cups of coffee
  • Hypertension, also called high blood pressure
  • Muscle cramps that can potentially interfere with exercise and performance
  • Insomnia from increased energy

Clenbutrol is not toxic to the kidneys or liver. Even so, if you experience any discomfort while using Clenbutrol, be sure to cease use and see a doctor.

Where to Buy Clenbutrol

You can purchase Clenbutrol directly from While their products are all top-notch, they’re also kind of pricey – however, you can get a real bargain if you buy two bottles because they’ll throw in a third bottle for free.

They will also ship FREE to anywhere in the world, with discreet packaging and tracking information provided. Plus, if you’re not happy with any of the products, you can return the unused portions for a full refund.

Bottom Line – Does it Work

The fitness world knows about the effects of clenbuterol, so can an imitation really hold up? Based on my experience, Clenbutrol has a lot to offer, and is one of the best cutting supplements out there.

I took three Clenbutrol pills per day for 30 days – not enough time to cycle, but enough time to enjoy regular doses – and I was impressed right from the start. When combined with plenty of time on the weight bench, I was able to gain muscle, lose weight, stop binging, and see results that made my gym buddies jealous – enough so that a few of them even started taking it with me.

I have to admit to being a little skeptical – Clenbutrol isn’t the same as clenbuterol, after all – but my doubts were misplaced. After a month of use, I can definitively say that Clen helped me look better, feel better, and really helped me make progress in the gym.

And as other men who struggle from time-to-time already know, that’s not always an easy accomplishment!
