CLENBUTEROL
(Spiropent)
Is available in 10 - 20 mcg tablets or in the .016 mg/gram
Ventapulmin Vet variety. 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 it's 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
clenbuterols 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. 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.
