What is Clenbuterol? Everything You Need To Know

However, female athletes are especially fond of this drug as it doesn’t have any androgenic properties – meaning thosewho use it do not develop deep voices, higher hairlines or acne. It keeps their estrogen levels firmly in place, so they can still retain looking very feminine. This is the best and most effective protocol in the long-term, as it involves slowly and gradually raising your dose. Increase the initial dose (40mcg in men and 20mcg in women) by 20mcg’s every fourteen (14) to seventeen (17) days.

• It keeps your body burning fat when it otherwise would try to preserve it.
• The alternatives I found use natural ingredients to produce the same fat-burning results as the original.
• Females will rarely take 120mcg of Clenbuterol, but some of the more hardcore and experienced women have been known to reach that dosage.
• When it comes to the regulation of pharmaceutical-grade Clenbuterol, you are certainly still taking a legal risk when you buy it without a genuine medical need and a prescription from a doctor.

Clenbuterol isn’t a steroid, but it has properties similar to anabolic steroids, such as promoting an increase in muscle mass. Due to these properties, clenbuterol has been used in livestock to increase the amount of lean muscle. With almost a decade of being in the fitness industry, I’ve worked with athletes and bodybuilders who asked about and who actually used clenbuterol to lose excess fat and increase lean muscle mass. Clenbuterol is a long-acting β-agonist used in oral and inhaled form for asthma treatment outside the U.S. and in veterinary medicine within the U.S. Toxicity with clenbuterol is increasingly seen in U.S. hospitals, primarily in younger individuals using the drug for competitive athletics or bodybuilding. We present a case of a young patient who presented after an intentional overdose and discuss the relevant literature.

When it comes to noticeable fat loss, the pace of your results will considerably depend on how hard and often you are working out and your diet. Clen is a tool to boost the results you’re getting – so the more dedicated you are to work out, the faster you will notice fat being lost, and for most people, this will be well within the first two-week cycle. Anabolic steroids and other types of fat loss and performance PEDs are often stacked with Clen. Clenbuterol has often been called an anabolic drug, but this is not thought to be the case because there is no evidence that higher doses can result in muscle gains in humans (even though it has been shown to do so in animals). Clenbuterol can preserve existing muscle while you’re on a calorie-restricted diet. By nutrient partitioning, Clen can prevent fat from being stored, encourage the use of fat for energy, and prevent the use of lean muscle.

With this approach, you’ll gradually increase the initial dosage by 20mcg every 2 weeks as needed. This cycle ensures that the body isn’t caught off guard, allowing it to continue guessing and not fully adapt to the compound; making it effective throughout the whole of your cycle. This is why it’s really important to take clenbuterol responsibly, to avoid any potentially life threatening side effects. Symptoms of an overdose may begin immediately and last for hours or even days.

Availability of Clenbuterol

Clinical research on Letrozole clenbuterol was abandoned due to unacceptably high risk in humans. Animals (horses, in particular) can tolerate the types of doses required for positive effects on muscle and fat — even adjusted for weight, similar doses of clenbuterol would kill a human being. In mice, clenbuterol caused changes in the activated genes for the beta-2 receptor, proteins involved in fat metabolism, and several muscle proteins. It may cause similar changes in humans too, which can have varying effects 13. If you’re an athlete or a bodybuilder, you may have heard of clenbuterol. This drug is widely used by bodybuilders as a weight-loss supplement, although it’s not FDA-approved for humans.

Three-time Tour de France winner Alberto Contador may be the most famous athlete to have used this excuse after testing positive for clenbuterol. (1) Thompson, Jessica, «Effects of clenbuterol on skeletal and cardiac muscle in horses» (2009). However, clenbuterol is purchased on the black market, where supplements are often tainted (10); thus, it is difficult to know if users are receiving 100% real, authentic clenbuterol.

Often considered more stimulant than a true steroid, Clenbuterol is notorious as a powerful fat burner that works by increasing thermogenesis and thus raising the metabolism. This helps burn off stored fat as the body is constantly at a heightened metabolic rate, even at rest. Clenbuterol was previously given to livestock to increase lean muscle mass and livestock production.
