Of all the supplements commercially available to help with a fat-loss diet and training program, the combination of ephedrine and caffeine (EC) is probably the most potent. In a number of studies, EC
has been shown to increase metabolic rate, blunt appetite, increase fat-burning and spare muscle loss during a diet. EC acts as a stimulant and thus can be used as a workout booster. Chronic use of
EC is associated with a lessening of the stimulant effect, although the fat-burning abilities persist.
Taken at a dosage of 20 milligrams (mg) of ephedrine and 200 mg of caffeine (or their herbal equivalents of, respectively, mahuang and kola nut or guarana), this stack is considered a reliable thermogenic with minimal side effects (typically, jitters, insomnia and an increase in heart rate and blood pressure are recorded - similar to the use of any stimulant).
Although EC may seem like the perfect fat-burning stack, it can be improved with the addition of some useful products. Let's look at two and see how they work. L-Tyrosine The amino acid L-tyrosine is a precursor to the catecholamine hormones epinephrine and norepinephrine, which are involved in the working of the EC stack. By providing sufficient L-tyrosine (500-1,000 mg) with each dose of EC, you can ensure adequate substrate for epinephrine and norepinephrine release. Many people who have used an EC stack for a prolonged period and then add L-tyrosine also report a regeneration of the stimulant and appetite-suppressant effects. This makes the addition of L-tyrosine useful for those taking EC solely as a workout booster
Green Tea Green tea has been used for centuries in the Orient for weight loss, and we now know how it works. One of the compounds in green tea inhibits the enzyme catechol O-methyltransferase (COMT), which breaks down epinephrine and norepinephrine. This means that the effects of EC are prolonged, although not necessarily increased. Many people report a "crash" a few hours after taking a dose of EC; the addition of green tea extract may help to prevent this, as well as keeping the EC stack burning fat longer.
Simply adding L-tyrosine and green tea to your EC stack can make it work better and longer. Coupled with a proper fat-loss diet and training program, these combos can only result in faster and more efficient fat loss.
