The Ultimate Guide to Running a Clenbuterol Cycle

For more than four decades Clenbuterol has been known to the medical world as an effective medication for asthma. Indeed, Clenbuterol is a known  bronchodilator and β2-adrenoceptor agonist that was originally synthesized for the purpose of providing long-lasting medical treatment for patients suffering from one respiratory ailment or another, such as; recurrent airway obstruction (RAO) and inflammatory airway disease (IAD).

However, the bodybuilding community has over the years realized that Clenbuterol or Clen offers significant cutting benefits. Many bodybuilders have been known to run Clen cycles to burn body fat and maintain lean muscle mass gains within a short space of time during their respective training programs.

Clenbuterol is also known to be used by bodybuilders in their off-season or during recovery because of its potent anti-catabolic properties. There is no doubt that Clen is one androgenic-anabolic steroid (AAS) that is worth considering by any bodybuilder looking to run a cutting program.

In this ultimate guide to running a Clenbuterol cycle, we reveal the benefits of running a Clen cycle, the possible side effects users could be exposed to, and the recommended Clen cycle, stack and dosage plans for both men and women.



Benefits of Running a Clenbuterol Cycle

In addition to the ease of use and convenience offered by Clenbuterol during oral administration, this AAS is known to offer many more bodybuilding benefits, such as:

#1. Fat Reduction

Clenbuterol is known to increase core body temperature by as much as one degree by stimulating the central nervous system (CNS) and boosting adrenaline output.

The increase in core body temperature or thermogenesis will lead to the stimulation of sweat glands to produce more sweat to cool down the body temperature and achieve homeostasis. The switch between thermogenesis and homeostasis will lead to a greater use of calories and an increased basal metabolic rate. The effect of this is increased fat loss through the burning of a greater amount of calories even on your rest or recovery days.

#2. Improved Athletic Performance

By stimulating the CNS and boosting the release of adrenaline into the bloodstream, Clenbuterol will increase the availability of oxygenated blood flow throughout the body.

A boost in oxygen-rich blood in muscle tissues will help to reduce lactic acid accumulation which is primarily responsible for muscle fatigue.

Therefore, improved athletic performance is one Clenbuterol benefit that bodybuilders look forward to as it helps bodybuilders to train longer and harder than before to build and maintain lean muscle mass.

#3. Improved Recovery Time

One problem that many bodybuilders face during their training programs is a longer than needed recovery time.

Clenbuterol can greatly reduce the time needed to recover from muscular injuries by increasing the red blood cells in your bloodstream and the supply of oxygen and nutrients to damaged muscle tissue for quicker healing.

Clen will also stimulate protein synthesis in skeletal muscle tissues to promote quick muscle repair and growth.

#4. Energy Boost

As mentioned already, Clenbuterol will stimulate the central nervous system to increase the production and release of adrenaline in the body.

This boost in adrenaline will give Clen users the energy needed to successfully engage in their respective strength training programs. The good news about using Clenbuterol is that it does not suppress endogenous testosterone levels unlike other androgenic-anabolic steroids. Testosterone suppression is a widely known cause of fatigue and tiredness.



#5. Appetite Suppressor and Potent Diuretic

Clen is known to stimulate beta 2-adrenergic receptors and in effect increase a users level of satiety. This is particularly great when running a cutting program, as Clen will not only stimulate fat loss, but also stop you from engaging in indiscriminate or binge eating.

With Clenbuterol, you will not only burn body fat, but you will also flush out any extracellular water in your body mainly through increased sweating, as Clen is an active diuretic.

Clen does not promote water retention which means that you should expect a lean, hard, dry and vascular muscle tone when you run a Clenbuterol cycle.


Possible Clenbuterol Side Effects

Clenbuterol like any other orally administered AAS can expose users to some side effects. However, it must be mentioned that users may react in different ways when they run Clenbuterol cycles due to several factors including their gender, age, body mass index (BMI), cycle length and dosage plan.

Nevertheless, s9me known Clenbuterol side effects that you should be wary of are:

#1. Elevated Heart Rate

Clenbuterol will stimulate your central nervous system to boost adrenaline production and release. While this can lead to several bodybuilding benefits as explained earlier, it can also cause you to experience a heightened resting heart rate.

If you suffer from high blood pressure or hypertension, then it is advisable to avoid using Clenbuterol, especially without first consulting your personal physician.

#2. Depression and Anxiety

As Clenbuterol can stimulate your CNS and in effect put you in a fight or flight mode by boosting adrenaline output, the hormonal changes brought about  by your use of Clen can affect your mental health by causing depression and anxiety.

#3. Hyperactivity and Insomnia

With Clenbuterol increasing your adrenaline output, it puts you in a hyperactive state that may affect your sleep quality and cause Insomnia. There are bodybuilders that prefer taking their daily Clen dosage early in the day and before their training sessions, as they believe this will enable them to sleep well at night.

However, it must be said that Clenbuterol has a 35 hour half-life, which means that it will take about one and a half days before the active compound leaves your system and because of this, taking Clen in the early morning is no guarantee that you will experience a good night’s sleep at bedtime.

The dangers of Insomnia is that it could lead to higher cortisol (stress) hormone levels which in turn increases your blood pressure while also limiting fat loss.



Recommended Clenbuterol Cycle and Dosage Plan for Bodybuilding

If you have decided to run a Clenbuterol cycle for your bodybuilding cutting program, then you might want to consider this Clenbuterol cycle and dosage plan for both male and female bodybuilders.

Week 4 90mcg (day 22-24), 100mcg (day 25-27), 110mcg (day 28-30)

Clenbuterol and Winstrol Stack

Clenbuterol can be stacked with other oral AAS like Winstrol. A Clen and Winstrol stack is popular amongst bodybuilders looking to achieve lean muscle mass and fat loss gains as quickly as possible.

However, you are advised to use liver protection supplements like TUDCA, LIV-52 or Samarin, as Winstrol is known to be hepatotoxic in nature and can cause liver damage if care is not taken.

Clenbuterol is legal in many countries including the U.S and it is not one of those AAS listed under the Controlled Substances Act.

Nevertheless, Clenbuterol has not received FDA approval and it is one of the banned substances listed by WADA. So as an athlete or competitive bodybuilder, you could stand the risk of a suspension or ban if you are caught using Clenbuterol.

However, Clen is an effective fat burning compound that does not suppress endogenous testosterone levels and can be stacked with other anabolic steroids like Anavar and Winstrol for optimal bodybuilding and performance-enhancing gains.
