Clenbuterol - "A substituted phenylaminoethanol that has beta-2 adrenomimetic properties at very low doses. It is used as a bronchodilator in asthma." Medical Dictionary

Clenbuterol 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.

HOW DOES IT WORK
“Clenbuterol works the same way as ephedrine. However, unlike ephedrine, which is out of the body in a few hours, clenbuterol lasts for days. So you are on it 24 hours a day. No one chooses to be on ephedrine 24 hours per day, because it interferes with sleep, and so clenbuterol is more effective” says Bill Roberts (Bill Roberts holds a bachelor's degree in Microbiology and Cell Science, and a doctoral degree (Ph.D.) in Medicinal Chemistry)

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.

SIDE EFFECTS
The possible side effects of clenbuterol include those of other CNS(central nervous system) stimulants, and include such occurrences as shaky hands, insomnia, sweating, increased blood pressure and nausea. These side effects will generally subside after a week or so of use however, once the user becomes accustomed to the drug. Another thing people should be aware of is the inherent liver toxicity associated with clenbuterol use. When stacking with oral 17-alpha-alkylated steroids, accutane, anti-biotics or other hepatoxic elements, one should have his liver values checked by a licensed physician at regular points in time to avoid all problems. If you not a yellow discoloration of the skin cease use immediately and contact your doctor.

STACKING CLENBUTEROL WITH OTHER SUBSTANCES
Caution is advised when employing the use of Clenbuterol in conjunction with other adrenoceptor agonists as side effects are likely to be cumulative. It is for this reason that it is generally not recommended to use ephedrine/ephedra (or ma huang) or the ECA stack (ephedrine-caffeine-aspirin) whilst using clenbuterol. In view of the above side effects, it is obvious to assume that anyone with cardiac issues and/or hypertension should not use a stimulant such as Clenbuterol and caution must be observed by those already using similar compounds in the treatment of existing medical conditions. In addition, there is very little conclusive knowledge of the cardiac effects of supra-physiological dosages in humans.

USAGE
It is well known that Clenbuterol use results in rapid down-regulation of beta 2 receptors. This is due to the powerful stimulatory effect of the drug. It is therefore pointless to use clen for long periods without a break. Some believe that a two day on, two day off dosing schedule will allow adequate potential for receptor up-regulation. However, I doubt this to be the case due to the relatively long half life of clen, resulting in continued stimulation even throughout the 'off' days. A much better regime would be a two week on, two week off cycle. Maximum plasma levels are reached around 2-3 hours after oral administration, and terminal half life at 34 hours (Zimmer, 1976).

It is recommended to start by taking one 20mcg tablet on the first day and then increase the dosage on the subsequent days by one tablet until the needed dosage is reached. For fat loss, clenbuterol seems to stay effective for 3-6 weeks, then it's thermogenic properties seem to subside.

There are many theories on what is the best schedule: a two week on, two week off, or one week on, one week off. Steroids-Shop.Net suggests you to find out what works best for you through experiencing. During the two 'off' weeks, an ECA or Ephedrine stack can be used as required.

Before starting new cycle you must wait at least for two months.

You also must be very well hydrated.

WILL CLENBUTEROL HELP ME BURN FAT?
DIET AND CARDIO are MOST IMPORTANT in this process! If one sits all the day in front of TV eating all he wants, effectiveness of Clenbuterol will be GREATLY reduced!
So, training, diet, cardio and supplements should be “taken” together. Do not try to use short cuts because they do not work!

Chemically clen is not a steroid hormone but a beta-2-agonist. This means it is in the same family as ephedrine and produces similar but more pronounced effects. Although banned in Canada and the United States, it is used in many European countries as a bronchodilator in Asthma medications.

Clen owes much of its popularity to the animal food industry. Farmers discovered that clen was a potent way to pack lean muscle tissue on their livestock. As with steroids, once word started circulating around that clen had such effects, bodybuilders started placing orders with their local dealers.

Anabolic properties!

Bodybuilders compare clenbuterol to such steroids as Winstrol and Oxandrolone, The drug is mildly anabolic with great fat burning properties. Clen also has strong anti-catabolic effects. This means it reduces the rate at which protein is removed from muscle tissue and used as a fuel source. As bodybuilders have discovered a compound that is anti-catabolic will promote muscle growth nearly as effectively as an anabolic agent. It’s for this reason that numerous athletes use Clenbuterol after their steroid cycles in order to prolong their strength and muscle gains.

Fat burning too!

While clen is popular for muscle building, it’s the fat burning effects that really cemented its popularity as a precontest drug. Like ephedrine, Clen is a thermogenic drug that burns body fat by slightly elevating the body’s temperature. This makes existing fat stores more susceptible to fat burning during aerobic exercise. It should be added that increasing body temperature is believed to magnify the effects of steroids, since the rate of protein processing is increased.

How much?

Male bodybuilders usually take 5-7 tablets per day. As the most popular forms of clen come in 20mcg tablets, this works out to 100-140 mcg per day. Females usually take 80-100 mcg/day. As with steroids and other performance enhancing drugs, clenbuterol is usually taken in cycles of 8-10 weeks – primarily during the precontest season.

Side effects?

Since Clen is not a hormone like testosterone or steroids, it has no androgenic side effects typical of these compounds (one of the reasons why the drug is so popular with female bodybuilders and fitness competitors). But rest assured clen does carry with it a whole host of side effects. As a beta-2 agonist the drug produces most of its effects on the sympathetic nervous system. These include: insomnia, heart palpitations, hand tremor (involuntary trembling of fingers), moderate to severe headache, increased perspiration, muscle spasms, elevated blood pressure, and even nausea. While most of these side effects are temporary in nature and usually cease after 8-10 days of use, they could lead to more severe problems.

A safe alternative!

Given that clenbuterol is potentially dangerous and banned by most sports’ federations, bodybuilders would be wise to look for legal alternatives. Thanks to rapid advances in supplement research over the past decade, bodybuilders now have at their fingertips powerful steroid analogs that will promote rapid gains in lean muscle tissue while at the same time strip body fat from the body. These legal steroid analogs are both safe and legal and made with pharmaceutical grade ingredients. So play it safe, play it legal, and check them out!
