Clenbuterol used to be a bronchodilator in the treatment of bronchial asthma. Today this type of usage is forgotten, and you can only find it in bodybuilding/fitness. One of the reasons is that clenbuterol helps you lose fat and gain muscle mass. Results are noticeable after the first week of usage. This drug is popular in women due to weight loss and this one achieves it at rapid rate. It works in the way that it increases the body temperature resulting in the loss of fat. That works for belly, buttocks, legs and arms. The most popular form of taking it is by pill. It is much safer than other forms. Pills come in packages of 20 mg or 40 mg and are taken 5 minutes after training on a low carbohydrate diet. Even though it burns fat and makes improvements in muscle mass, don’t take it without being committed to training. When we talk about dosages, we have to separate for men and women. Men can use up to a 120-140 mg per day, but women should keep it less than 80-100 mg per day. Those doses are safe and any more than that might result into side effects. There are various cycles but the most popular cycle among the bodybuilders is 2 weeks on and 2 weeks off. The reason is that body gets used to it, generates tolerance and stops making any effects. Most people start with dosages such as 40 mg for men and 20 mg for women gradually increasing it. If you exceed 140 mg per day or take it more than 16 weeks per year, side effects might appear. Those side effects are cardiovascular issues, increased blood pressure, nervousness, sweating… So, follow cycles, dosages and take this drug responsibly.
