Taking Clenbuterol: Uses, Side Effects, Risks and More

Despite this basic-looking cycle, excellent fat loss and enhancing muscular definition results can still be achieved. This cutting cycle makes use of the powerful fat loss steroid Anavar, which will compound significantly on the effects of Clenbuterol. The above cutting cycle is suitable only for those who understand and know how to address the side effects of anabolic steroid use. More experienced users will almost always be stacking Clenbuterol with other more powerful substances like anabolic steroids. The Clenbuterol portion of any cycle will rarely change much or at all whether you are a beginner or advanced user because how we cycle Clen is very different from how steroids are used.

Best Cycle Support – Liver, Kidney, Cholesterol Support

Alcohol will exacerbate all three of these side effects due to increased cortisol production, so it should be avoided. The Peking Union Medical College in Beijing, China, concluded that clenbuterol only had mild effects when given to rabbits (7). However, when higher doses were administered, their heart rates increased drastically, inducing severe hypotension. However, bodybuilders will often stack Cytomel with testosterone or another anabolic steroid due to its catabolic effects. A 2-week cycle will often start in the 20–40 mcg range, with the dose increasing every 1 or 2 days until a maximum dose is achieved (usually 100 mcg–140 mcg). Clenbuterol is a powerful stimulant, more so than any standard pre-workout; thus, energy levels will increase notably.

Anxiety is a common side effect of taking clenbuterol due to its tendency to shift a person into fight-or-flight mode. Excessive arousal of the central nervous system may cause a person to perceive everyday situations as threats, negatively affecting their mental health. Dr. Thomas O’Connor also has anecdotal evidence of clenbuterol contributing to heart rates of 180 beats per minute. Therefore, it is important to drink adequate levels of water when taking clenbuterol, as sodium is lost through sweat, which can lead to dehydration and muscle cramps. Thus, we have seen clenbuterol improve muscular endurance, enabling bodybuilders to perform more repetitions than usual in less time. The truth may lie somewhere in the middle, with clenbuterol having anabolic properties, although not to the degree of anabolic-androgenic steroids.

However, due to the hidden dangers of the drug, there can be serious risks for those who take it regularly. Clenbuterol can reduce the amount of naturally occurring potassium in the body. Consequently, those taking it as a drug will often also eat extra portions of bananas to replace the substance.

Clenbuterol vs. Cardarine

A study from the National Library of Medicine shows that those using Clenbuterol Cabergoline in USA may notice an increase in blood flow and muscle oxygenation, which speeds up the delivery of nutrients, aiding in muscle recovery and growth 5. However, its overuse can lead to it becoming a powerful performance enhancer and fat burner. According to the National Institute of Health (NIH), Clenbuterol, commonly used for bronchial asthma, can ease breathing by relaxing lung muscles and increasing airflow, which improves oxygen circulation 1. After five weeks of research, I’ve compiled my data in this article so both you and my clients can make an informed decision and be aware of all potential risks and benefits. Urine toxicology panel, serum salicylate level and serum ethanol level were all negative the night of admission.

• We previously showed that SKM-β-arrestins do not contribute to the beneficial metabolic effects caused by clenbuterol administration19.
• The serum potassium level was noted to be 2.2 mEq/L and magnesium 1.6 mEq/L.
• Thus it’s optimal to keep cycles short, otherwise you’ll be wasting your money.
• Treatment data were recorded for the last 3 days of clenbuterol treatment (see Supplementary Fig. 9a for a scheme of the experimental design).

Clenbuterol was banned for livestock in most countries since large amounts of the drug can enter the body when eating the contaminated meat. That appeared to be the case for Spanish cyclist, Alberto Contador, who failed a Tour de France drug test in 2010 18, 19, 17. Although diverse, all the effects are caused by activating beta-2 receptors found throughout the body 1. SelfHacked has the strictest sourcing guidelines in the health industry and we almost exclusively link to medically peer-reviewed studies, usually on PubMed.

Neither of these drugs will cause any water retention, meaning any weight you gain will be in the form of lean muscle tissue. Always keep in mind that clenbuterol should be cycled properly (not only to avoid bad side effects), but also for effectiveness. Although a user’s gains from a clenbuterol cycle will vary from person to person; the approaches mentioned in this article have been proven to be the most effective of cycles – helping bodybuilders burn fat and retain muscle mass. “There are serious health risks when taking clenbuterol including heart damage and death,” says Brown. One of drugs promising that is clenbuterol, better known as ‘clen’ among the gym community.
