Manufacturer: NIHFI, Bulgaria Clenbuterol is known as a sympathomimetic. These hormones are taken to mimic adrenaline and noradrenaline in the human body. Clenbuterol is a selective beta-2 agonist that is used to stimulate the beta-receptors in fat and muscle tissue in the body. Clenbuterol exhibits most of its effects on the stimulation of both type 2 and 3 beta-receptors. It is effective in helping to burn bodyfat. Clenbuterol is also effective in increasing muscle mass and decreasing fat loss. Clenbuterol generally come is 20 mcg tablets, although it is also available in syrup. Users will usually tailor their dosage individually, depending on results and side effects, but somewhere in the range of 2-8 tablets per day is most common. Clenbuterol is often stacked with Cytomel. For fat loss, Clenbuterol seems to stay effective for 3-6 weeks, then it's thermogenic properties seem to subside. This is noticed when the body temperature drops back to normal. Its anabolic properties subside much quicker, somewhere around 18 days. Clenbuterol is attractive for its pronounced thermogenic effects as well as mild anabolic properties. A number of medical reviews have cited its outstanding potential to promote muscle gains as well as fat loss and weight loss. There have been an increasing number of American bodybuilders that are experimenting with this drug. Many athletes who use Clenbuterol claim that it promotes dramatic strength increases and a very noticeable reduction in body fat and weight loss. Some athletes claim that they enjoyed significant gains in muscle mass while using Clenbuterol. Clenbuterol's most valid application seems to be as a pre-contest, cutting drug. It is not banned by any athletic committee; thus, numerous professional bodybuilders have used it for the last month of contest preparation. Cycles range from 6-12 weeks in length. Side effects include nervousness, tremors of the hands, headaches, and insomnia. The reason although it is fairly anabolic, and it promotes the burning of fatty acids through brown fat burning. Dosages are normally between 20-120 mcg for bodybuilders that use this.This drug becomes ineffective for its anabolic properties after 18 successive days of use. Brown fat-burning and weight-loss, will continue past the 18 day period. After 12 weeks, the drug should be discontinued for a couple of months. Although there is quite a bit of medical literature showing clenbuterol's potential as a bodybuilding drug, most of these studies have been done on animals; very little human data on this issue is available. Therefore, in assessing its effects in humans, you have to rely primarily on empirical and anecdotal evidence. And until recently, there has been little of that available. However, with the recent wide scale use of clenbuterol by athletes, we can now gather quite a bit of evidence on what the real world effects of Clenbuterol are in weight trainers. To say that Clenbuterol use is rampant in bodybuilding right now would be an understatement. Thousands and thousands of athletes are using this drug. I personally know a number of pro football players, foreign Olympic athletes, and professional bodybuilders who are using clenbuterol. In addition, I have received feedback from at least 200 other athletes who have experimented with this novel compound. Generally, the feedback from clenbuterol users is that the drug produces dramatic body composition alterations. One Canadian strength coach compared the results he has seen in athletes using Clenbuterol to what one might experience while using a stack of Anavar and Halotestin. Within weeks of beginning Clenbuterol therapy, many athletes notice a significant strength increase and a dramatic reduction in body fat. The results that occur secondary to Clenbuterol administration seem to occur equally in men and women as well as young and old. The trick of using Clenbuterol successfully seems to be avoiding receptor downgrade which occurs rapidly with the use of this beta agonist. In fact, one clinical study showed downgrade at receptor as much as 50% experienced after using Clenbuterol for as little as 18 days consecutively. The same study showed that attenuation can be avoided if Clenbuterol is taken in a '2 day on' then '2 day off' pattern. Athletes using Clenbuterol in this manner have reported much greater results than those who use the product continualy which seems to support the theory that attenuation can be at least partially avoided by staggering the dosage. Athletes have also made a habit of cycling Clenbuterol in an effort to minimize side effects as well as prevent receptor downgrade. Average cycle length on Clenbuterol is 8-10 weeks with a 4-6 week off period.
