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.
Clenbuterol is really one of bodybuilding's most misunderstood performance enhancement drugs. It is true that it is effective in helping to burn bodyfat but it is often been stated that
clenbuterol is effective in causing anabolic gains and has in times even been compared to some of the weaker anabolic steroids. Books such as the World Anabolic Review, 1996, by P. Grunding and M. Bachmann state incorrectly that, "its effects, however, can by all means be compared to those of steroids. Similar to a combination of Winstrol Depot and Oxandrolone...." These statements are inaccurate and misleading to say the least. A lot of these claims as to the anabolic effects of
clenbuterol are derived from studying the effects of
clenbuterol on livestock.
Clenbuterol is effective in increasing muscle mass and decreasing fat loss in animals.
The problem with the variation in anabolic effects between humans and livestock is that livestock have an abundance of the type 3 beta receptors whereas humans have little if any of the type 3 beta receptors. These beta-3 receptors increases
insulin secretion and sensitivity, causing more glucose and amino acids to be transported into skeletal muscle thus causing the anabolic effects that we, humans, just aren't seeing. As Dan Duchaine stated in his Muscle Media article on
clenbuterol, "In those animal research studies showing an anabolic effect from
clenbuterol, it's my guess the anabolism happens specifically when the beta2 receptor stops working. At that point, the beta3 increases and causes the anabolic effect through
insulin mechanisms." Since humans, again, have either very little or no beta-3 receptors, there is no chance of this anabolic effect. Just another of the studies where everyone assumed that what works in animals must work in humans. This is just simply not the case with
clenbuterol.
Clenbuterol does work effectively as a
fat burner though. It does this by slight increases in the body temperature. With each degree that the temperature in your body is raised from the use of
clenbuterol, you will burn up approximately an extra 5% of maintenance calories. This makes it effective as a
fat burner. Your body will fight this by cutting down on the amount of active thyroid in the body as well as through beta-receptor down regulation, which explains why you only have a limited effective period to take
clenbuterol. While I am on the subject of beta-receptor down regulation, I would like to dispose of another myth. This involves the two on/two off cycling theory that I believe was originated by Bill Phillips in the Anabolic Reference Guide and has somehow made it's was into every other steroid book since then including the WAR and Physical Enhancement with an Edge. The two on-two off theory simply will not work because of one main reason: the half life of
clenbuterol. This 2-on/2-off idea was a THEORY ONLY, not by a doctor or scientist, and not based on specific knowledge of
clenbuterol, but derived by imitation from other drug's with shorter half lives.
Clenbuterol has been reported as having a half life of about 2 days, but that is not actually correct, since it has biphasic elimination, with the half-life of the rapid phase being about 10 hours, and the slower phase being several days. Supposedly, this is one of the reasons the FDA never approved
clenbuterol as an anti-asthmatic drug...the FDA frowns on drugs with long half-lives if drugs with more normal half-lives are available. So with a 2-on/2-off cycle you never have time to get enough of the
clenbuterol out of your system for this theory to be reasonable. In actuality, it probably hasn't even dropped to 50% of your peak concentration before you are taking the drug again. With this all taken into account, there is no reason to think that this cycling would significantly reduce the problem of receptor desensitization. A more reasonable approach would be either one week on, one week off, or alternately, two weeks on two weeks off. The two week cycle has the disadvantage of a "crash" period afterwards. This crash period can be helped with the use of ephedrine to lessen the lethargy that you will experience.
If you are interested in taking
clenbuterol for anything other than fat loss then you might as well stay away from this compound. There is a lot of talk as to how
clenbuterol compares to ephedrine as well. Most "experts" feel that
clen gives a better bang for the buck than the ECA stack. It should be noted that
clenbuterol’s results and effects are much shorter lived. They work through very similar mechanisms. Both products stimulate the beta-receptors but
clenbuterol seems to be a more refined version, called a second generation beta-agonist drug, than ephedrine.
Clenbuterol targets the proper receptors, being the beta-2 and 3 receptors than ephedrine more specifically which should in theory make
clenbuterol more effective of a
fat burner. Again, most of the so called "experts" say that
clenbuterol is more effective than ephedrine. I, personally, get worse results with
clen vs. the good old ECA stack.
Clenbuterol also didn't blunt my hunger either and I ate more while taking it as well. I also seem to get much better effects out of
cytomel as a
fat burner as well. Even better than the ECA stack or
clenbuterol. But, again, that is my personal opinion.
Effective Dose: 80-140 mcgs. / day in split doses throughout the day. Anything over 140 mcg a day is overkill since the beta receptors can only take so much of a product and then more is just wasteful.
Street Price: $.50 - 1.00 / tab. Fairly inexpensive in Mexico though. Spiropent is currently going for about $7.50/box, Novegam for $5.25/box, and Oxyflux for about $3.30/box.
Stacking Info: One week on, one week off might make sense, or alternately, two weeks on two weeks off makes sense but has the disadvantage of a "crash" period afterwards. You can take ephedrine after the
clen to help reduce this "crash" period or at least make it more bearable for you. The two on/two off theory is absolute bullshit and can't work; read above.
Clenbuterol:
Clenbuterol, medically used throughout many parts of the world as a broncodilator for the treatment of asthma, is a recent and popular addition to the realm of athletics.
Clenbuterol is a beta-2 agonist, with properties somewhat similar to adrenaline. It acts as a CNS stimulant and users quite commonly report side effects such as shaky hands, insomnia, sweating, increased blood pressure and nausea. These side effects generally subside quickly once the user becomes accustomed to the drug. Athletes find
clenbuterol attractive for it's pronounced thermogenic effects as well as mild anabolic properties. Dosage regimes will vary depending on the desired effect.
Clenbuterol generally come is 20mcg tablets, although it is also available in syrup and injectable form. 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. 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. It's anabolic properties subside much quicker, somewhere around 18 days. Currently, counterfeits of
clenbuterol do exist, but they are scarce and most are bottles with loose tablets.
Clenbuterol should only be trusted when purchased in foil and plastic strips, preferably with accompanying box and paperwork.
Clenbuterol:
This is a very interesting drug, which has recently become popular amongst bodybuilders.
Clenbuterol itself, is a third generation beta agonist.
Clenbuterol's use as a bodybuilding drug item from a number of medical reviews which have cited its outstanding potential to promote muscle gains as well as fat loss. It has been used in parts of England for several years by a limited number of elite athletes. More recently, due to the steroid crackdown, there have been an increasing number of American bodybuilders that are experimenting with this drug.
Clenbuterol is indeed the most intriguing ergogenic aid I have studied with the sole exception of anabolic steroids.
Many athletes who use
Clenbuterol claim that it promotes dramatic strength increases and a very noticeable reduction in body fat 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. Athletes have used between 60-120 mcgs taken in divided doses daily. Because it causes a great deal of receptor downgrade it should not be used continually. Research shows that using it for two days, then taking two days off prevents attenuation. Cycles range from 6-12 weeks in length. Side effects include nervousness, tremors of the hands, headaches, and insomnia. Usually these side effects are dose related. It comes in 20 mcg tablets.
Clenbuterol is being counterfeited under numerous manufacturer names in the United States.
Clenbuterol:
This drug is classified as a beta-2 adrenergic agonist.
Clenbuterol is a bronchiodilator. This drug is banned by the FDA although it is used outside the US by asthma patients. The reason although it is fairly anabolic, and it promotes the burning of fatty acids through brown fat burning.
Clenbuterol is a little scary because of some other side effects including the following: tremors, sweating, sleeplessness, rapid heartbeat, etc. These side effects vary in people. Some people aren’t affected at all. This drug comes in tablets of 20 mcg (micrograms not milligrams ). Dosages are normally between 20-120 mcg for bodybuilders that use this. It should be taken in a 2 days on /2days off fashion because this drug becomes ineffective for its anabolic properties after 18 successive days of use. The receptor sites seem to be non-responsive for anabolic purposes if taken continuously, but brown fat-burning will continue past the 18 day period. It shouldn’t be used this way for more than 12 weeks. After 12 weeks, the drug should be discontinued for a couple of months.
