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. It is effective in helping to burn bodyfat. Clenbuterol is also effective in increasing muscle mass and decreasing fat loss.
Clenbuterol generally come is 20 mcg tablets, although it is also available in syrup. 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. Clenbuterol is often stacked with Cytomel. 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.
Its anabolic properties subside much quicker, somewhere around 18 days.
Clenbuterol is attractive for its pronounced thermogenic effects as well as mild anabolic properties.
Clenbuterol is a prescribed Asthma medication which is catabolic to fat and anabolic to muscle. Clenbuterol's most valid application seems to be as a pre-contest, cutting drug. It is a Beta-2 adrenergic agonist. This means it acts just like adrenaline (epinephrine) at a certain type of receptor named Beta-2.
Effective Dose: Clenbuterol is used at 60-120 mcgs per day, divided throughout the day. 2 days on, 2 days off / 2 weeks on 3 weeks off.
Pharmaceutical Price: In Mexico, 20 tabs cost $5.
Average Street Price: One Dollar or more per tab.
Cycles Cycles usually last 6-12 weeks. After 2 weeks, the Beta-2 receptors down regulate and impairment of T4 to T3 conversion is impaired. Research shows that using it for two days on then two days off prevents attenuation. Apparently, clen has a half-life in the body of 48 hours making it pretty much irrelevant when you take it. This means that two days on, two days off, conserves the number of pills you use in a cycle rather than for receptor downgrade which occurs around two weeks. The three weeks off between cycles counterbalances the receptor downgrade; the two days on, two days off reduces the side effects since on the third day of two-on two-off the concentration is highest.
Stacking: Ephedrine is not advised with clenbuterol as the negative side effects would be exaggerated. If you use Cytomel (25mcg/day) and Zaditen (ketotifene) at 10mg/day, you could cut your Clenbuterol dosage down to less than 1/2 and get a better thermogenic effect. Cytomel fights the deiodinase impairment. The Zaditen up-regulates the beta-2 receptor. On a clen cycle, a potassium supplement helps maintain your electrolyte status and reduces problems with muscle cramping.
Side Effects: Nervousness, tremors of the hands, headaches, early onset asthma and insomnia. As long as the electrolyte status is maintained -- (esp. potassium) clen does not cause too many problems. Muscle cramps are the most common. If you have a job that requires lots of manual dexterity then clen can be more problematic. The tremor it gives in the hands can make steady fine movements virtually impossible. Fortunately, this effect often diminishes over a week or two of continued usage. Clen can have some serious side effects (like sudden death) at very high dosages. Clen works but it is hard on your system. Buy a good blood pressure monitor and use it several times a day. Base your dosage on your BP and resting pulse and your lack of side effects.
