Clenbuterol is
a widely used bronchodilator in many parts of the world.
Clenbuterol is most often prepared in 20
mcg tablets, but it is also
available in syrup and injectable form. Clenbuterol belongs to a
broad group of drugs knows as sympathomimetics.
Clenbuterol
affect that sympathetic nervous system in a wide number of ways,
largely mediated by the distribution of adrenoceptors. There are
actually nine different types of these receptors in the body,
which are classified as either alpha or beta and further
subcategorized by type number. Depending on the specific
affinities of these agents for the various receptors, they can
potentially be used in the treatment of conditions such as
asthma, hypertension, cardiovascular shock, arrhythmias,
migraine headaches and anaphylactic shock. The text Goodman and
Gillman's The Pharmacological Basis of Therapeutics 9'" Edition
does a good job of describing the diverse nature in which these
drugs affect the body:
`Most of the
actions of catecholamines and sympathomimetic agents can be
classified into seven broad types: (1) peripheral excitatory
action on certain types of smooth muscles such as those in blood
vessels supplying the skin, kidney, and mucous membranes, and on
the gland cells, such as those of the salivary and sweat glands;
(2) a peripheral inhibitory action on certain other types of
smooth muscle, such as those in the wall of the gut, in the
bronchial tree, and in blood vessels supplying skeletal muscle;
(3) a cardiac excitatory action, responsible for in increase in
heart rate and force of contraction; (4) metabolic actions, such
as an increase in the rate of glycogenolysis in liver and muscle
and liberation of free fatty acids from adipose tissue; (5)
endocrine actions, such as modulation of the secretion of
insulin, rennin, and pituitary hormones; (6) CNS actions, such
as respiratory stimulation and, with some of the drugs, an
increase in wakefulness and psychomotor activity and a reduction
in appetite; and (7) presynaptic actions that result in either
inhibition or facilitation of the release of the
neurotransmitters such as such as norepinephrine and
acetylcholine."
The drug
clenbuterol is specifically a selective beta-2 sympathomimetic,
primarily affecting only one of the three subsets of
beta-receptors. Of particular interest is the fact that
Clenbuterol has little beta-1 stimulating activity. Since beta-1
receptors are closely tied to the cardiac effects of these
agents, this allows clenbuterol to reduce reversible airway
obstruction (and effect of beta-2 stimulation) with much less
cardiovascular side effects compared to nonselective beta
agonists. Clinical studies with Clenbuterol show it is extremely
effective as a bronchodilator, with a low level of user
complaints and high patient compliance. Clenbuterol also
exhibits an extremely long half-life in the body, which is
measured to be approximately 34 hours long. This makes steady
blood levels easy to achieve, requiring only a single or twice
daily dosing schedule at most. This of course makes it much
easier for the patient to use, and may tie in to its high
compliance rate. To spite that clenbuterol is available in a
wide number of other countries however; Clenbuterol has never
been approved for use in the United States. The fact that there
are a number of similar, effective asthma medications already
available in this country may have something to do with this, as
a prospective drug firm would likely not find it a profitable
enough product to warrant undergoing the expense of the FDA
approval process. Regardless, foreign clenbuterol preparations
are widely available on the U.S. black market.
In animal
studies clenbuterol is shown to exhibit anabolic activity so
it's, obviously an attractive trait to the athlete.
Clenbuterol
is additionally a known thermogenic62, with beta-2 agonists like
clenbuterol shown to directly stimulate fat cells and accelerate
the breakdown of triglycerides to form free fatty acids. Its
efficacy in this area makes clenbuterol a very attractive, and
today almost mandatory, pre-contest drug. Those interested in
clenbuterol are most often hoping it will impart a little of both
benefits, promoting the loss of body fat while imparting
strength and muscle mass increases. But as was well pointed out
by a review published in the August 1995 issue of Medicine and
Science in Sports and Exercise, the possible anabolic activities
in humans are very questionable, and based only on animal data
using much larger doses than would be required for
bronchodilationb . With such reports there has been a lot of
debate lately as to whether or not clenbuterol is really
anabolic at all. Some seem to swear by the fact that it builds
muscle regardless, firmly sticking by "clen" as a great
off-season or adjunct anabolic. To others such reports are
confirmation that athletes have wasted valuable time and money
on drugs, what do not work as they are intended to by the user.
This debate continues today, with many still using clenbuterol
as a potential anabolic. With this in mind athletes will tailor
their dosage and cycling of this product individually depending
on which of the two "possible" results are more desired, and how
much side effects are to be tolerated. The possible side effects
of clenbuterol include those of other CNS 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. One would typically start a
cycle by gradually increasing the dosage each day until a
desired range is established. This process will minimize the
unwanted side effects seen from Clenbuterol; which otherwise
might be dramatic if a large dose is administered from the
onset. Men generally end up in the range of 2-8 tablets
of Clenbuterol per day,
although some people do claim to tolerate even higher dosages.
Women get by on iess, generally 2-4 tablets
of Clenubterol daily. Very quickly,Clenbuterol will elevate the body temperature. The rise is not
usually dramatic, perhaps a half of a Cegree or so, sometimes a
little more. This elevation is due to your body burning excess
energy (largely from fat) and is usually not uncomfortable. Now
that it is working, the number of consecutive days clenbuterol
can be used is believed to be dependent on the goal of the
individual. To be clear, the athletic benefits of
clenbuterol will
only last for a limited time and then diminish, largely due to
beta-receptor down regulation. When using it for fat loss. the
primary effect of the drug, it seems to work well for
approximately 4-6 weeks. During this period. users will want to
constantly monitor their body temperature. We are assured
clenbuterol is working by the temperature elevation. Once the
temperature drops back to normal, clenbuterol is no longer
exhibiting a thermogenic effect. At this point increasing the
dosage would not be very effective, and a break for at least a
few weeks should be taken before it is used
clenbuterol again effectively.
If one is looking for strength gains, clenbuterol appears to be
effective for a much shorter period of time, around 3-4 weeks.
This may be due to an absence of real anabolic effect, with the
strength gain seen with clenbuterol possibly due only to the
stimulant properties of the drug (similar to the strength boost
seen by Ephedrine users). Again however, this is still debated.
Many
competitors also find the fat burning effect of clenbuterol can
be further enhanced by additional substances. When combined with
thyroid hormones, specifically the powerful Cytomel, the
thermogenic effect can become extremely dramatic. This can be to
a point that the athlete could shred exceptional amounts of
extra fat during contest preparations, without a dramatic
restriction in calories. Such a mix can be further used during a
steroid cycle, eliciting a much harder look from the anabolics.
These cutting agents can often greatly inhibit extra fat storage
during the cycle, even when using strong aromatizing androgens.
A clenbuterol /Cytomel mix is also common when using growth
hormone, further enhancing the thermogenic and anabolic effect
of this therapy. |
