What is Clenbuterol?

Clenbuterol is a beta-2 agonist and is used in many countries as a broncodilator
for the treatment of asthma. Because of it's long half life, clenbuterol is not
FDA approved for medical use. It is a central nervous system stimulant and acts
like adrenaline. It shares many of the same side effects as other CNS stimulants
like ephedrine. Contrary to popular belief, Clenbuterol has a half life of 35
hours and not 48 hours.

Dosing and Cycling

Clenbuterol comes in 20mcg tablets, although it is also available in syrup, pump
and injectable form. It's also available as a powder in some areas. Doses are
very dependent on how well the user responds to the side effects, but somewhere
in the range of 4-8 tablets per day for men and 2-4 tablets a day for women is
most common. Clenbuterol loses its thermogenic effects after around 8 weeks when
body temperature drops back to normal. Its anabolic/anti-catabolic properties
fade away at around the 18 day mark. Taking the long half life into
consideration, the most effective way of cycling clen is 2 weeks on/ 2 weeks off
for no more than 12 weeks. Ephedrine or Yohimbine can be used in the off weeks.

Clenbuterol vs Ephedrine vs DNP

Ephedrine will raise metabolic levels by about 2-3 percent and 200mg of DNP
raises metabolic levels by about 30 percent. Clenbuterol raises metabolic levels
about 10 percent and it can raise body temperature several degrees.

DNP is by far the most effective fat burner but many people will never use it
because of the risks associated with it. It also offers no anti-catabolic
benefit. Although it does have anti-catabolic effect, ephedrine's short
half-life prevents it from being all that effective.

As far as side effects, Clenbuterol's are certainly milder than DNP's, and some
would even say milder than an ECA stack. There is no ECA-style crash on
Clenbuterol and many users find it easier on the prostate and sex drive. This
may in part be due to the fact that Clen is generally used for only 2 weeks at a
time.

Side effects

NAUSEA
NERVOUSNESS
DIZZINESS
DROWSINESS
DRY MOUTH
FACIAL FLUSHING
HEADACHE
HEARTBURN
INCREASED BLOOD PRESSURE
INCREASED SWEATING
INSOMNIA
LIGHTHEADEDNESS
MUSCLE CRAMPS
TREMORS
VOMITING
CHEST PAIN

The most significant side effects are muscle cramps, nervousness, headaches, and
increased blood pressure.

Muscle cramps can be avoided by drinking 1.5-2 gallons of water and consuming
bananas and oranges or supplementing with potassium tablets at 200-400mg a
day taken before bed on an empty stomach. Taurine at 3-5grams is a necessity in
minimizing cramps.

Headaches can easily be avoided with Tylenol Extra Strength taking at the first
signs of a headache.

Common Uses

Fat loss: The most popular use for Clen, it also increases muscle hardness,
vascularity, strength and size on a caloric deficit. For the most significant
fat loss, Clen can be stacked with T3. Diet: A high protein(1.5g per lb of
bodyweight), moderate carb(0.5g to 1g per lb of bodyweight), low fat diet(0.25g
per lb of bodyweight) seems to work best with Clen.

Alternative to Steroids: Clenbuterol has mild steroid-like properties and can be
used by non-AS using bodybuilder to increase LBM as well as strength and muscle
hardness. Diet: A moderate carb, high protein, moderate fat diet work well.

Stimulant/Performance Enhancement: It can be used as a stimulant, but an ECA
stack may be a better choice because of it's much shorter half-life. Diet: To
take full advantage of the stimulatory effects of Clen, carbohydrates must be
included in the diet. Ketogenic diets do not work well in this case.

Precautions: Is Clen for you?

The same precautions that apply to Ephedrine must be applied to Clen, although
some people find ECA stacks are harsher than Clen. It should not be stacked
with other CNS stimulants such as Ephedrine and Yohimbine. These combinations
are unnecessary and potentially dangerous. Caffeine can be used in moderation
before a workout for an extra quick. burst of energy.

A word on Ketotifen

Ketotifen is safe antihistamine used extensively some European countries to
treat asthma and allergies. It can up regulate beta-2-receptors that Clen down
regulates. Basically, it allows users to extend their use of Clen for 6-8 weeks
at a time. 2-3mg a day is ideal, 10mg as found in "superclen" can make users
extremely drowsy. It also increases the effectiveness of Clen so doses must be
adjusted accordingly. The downfall of this drug is its ability to induce
extreme hunger is some people, which is not a desirable state to be in when
dieting.

Cycling Clenbuterol

Most users that report bad side effects and discontinue use are those who use
high doses right at the start of the cycle. The worst side effects occur within
the first 3-4 days of use.

A first time user should not exceed 40mcg the first day. Increase by one tab
until the side effects are not tolerable

Example of a first cycle:

Day1: 20mcg
Day2: 40mcg
Day3: 60mcg
Day4: 80mcg
Day5: 80mcg(Note: Increase the dose only when the side effects are tolerable)
Day6-Day12: 100mcg
Day13: 80 mcg (Tapering is not necessary, but it helps some users get back to
normal gradually)
Day14: 60 mcgs
Day15: off
Day16: off
Day 17: ECA/ NYC stack

Example of a second cycle:

Day1: 60mcg
Day2: 80mcg
Day3: 80mcg
Day4: 100mcg
Day5: 100mcg
Day6-Day12: 120mcg
Day13: 100 mcg
Day14: 80 mcgs
Day15: off
Day16: off
Day 17: ECA/ NYC stack

What else do I need to know?

Taurine MUST be used with Clen at 3-5g daily. Clenbuterol depletes taurine
levels in the liver which stops the conversion of T4 to T3 in the liver.
Taurine allows the user to avoid the dreaded rebound effect and painful muscle
cramps. It's a must with Clen.


What is Taurine?

Taurine


Taurine, a sulfur containing amino acid derived from the amino acid cystine, is a component of the bile salts produced in the liver (it was first isolated from ox bile). It is important for proper digestion of fats and absorption of fat soluble vitamins. But only a fraction of available taurine is used to make bile salts,2 while an enormous amount floats freely inside cells.

Taurine is not incorporated into proteins but remains free in the tissues, especially muscle and nerve tissues. It has a number of therapeutic uses including acting as a membrane stabilizer and reducing arrhythmias of the heart. Taurine also enhances the contractile strength of heart muscle (called a positive inotropic effect)3, and thus can help treat heart failure which is a decreased ability of the heart to pump out all the blood that flows into it. When the heart is failing, the blood backs up and forces fluid out into the tissues (edema) by osmosis. This leads to either swelling of the legs or fluid in the lungs and shortness of breath, depending on which part of the heart is more involved.

In a 1984 animal study, taurine protected against heart failure, reducing mortality by 80 percent in the taurine treated group with no diminishment of cardiac function.4 In a later animal study in 1988, taurine was shown to lower blood pressure.5 My own clinical experience confirms some of these effects of taurine, and I commonly give it to patients with heart failure and high blood pressure.

Taurine is also beneficial for the eyes enhancing the rods and cones (the pigmented epithelial cells in the retina of the eye that serve as visual receptor cells). The greatest visual acuity occurs in the macular area of the retina near where the optic nerve enters from the back of the eye. With aging, the macula commonly degenerates as rods and cones die, often causing blindness. What causes the degeneration is not clear, but it is more common in diabetics and may be the result of free radical damage from ultraviolet light or oxygen exposure.6

A review of animal studies reveals that taurine appears to protect the eyes from macular degeneration.7 In one 1975 research report, a diet deficient in taurine was associated with retinal degeneration in cats.8 Thus, taurine can be part of a comprehensive approach to macular degeneration that also includes antioxidant nutrients, minerals, flavonoids, botanicals and chelation therapy (an intravenous therapy done in a doctor's office).

Because taurine is a neuroinhibitory amino acid, it may help treat seizure disorders. Some animal studies have suggested a role for taurine in controlling seizures, but the results are not consistent. In 1977, a cat with chronic epileptic seizures was successfully treated with taurine both orally and intravenously.9 Other studies have also suggested taurine's supportive role for seizures, but some clinical trials have shown limited benefits or have not confirmed this effect of taurine. I have used
taurine, in combination with magnesium and other nutrients, in my seizure patients with some success. It seems to enhance the effects of some of their seizure medications so they can take a lower dose.
