In the world of bodybuilding contest dieting, there are two big players. The first is Clenbuterol, an adrenergic agonist that stimulates the central nervous system to lose weight. The other, ECA, is a stack of ephedrine, aspirin, and caffeine, which work together to create a synergistic thermogenic effect in the body. Bodybuilding, fitness, and figure competitors to shed body fat and maintain high energy levels when preparing for a contest commonly use them both.
Clenbuterol, or ‘clen’ for short, does a number of things. First, it increases blood pressure. Oxygen transportation in the body increases as well. This means a person on less food can suddenly do MORE cardiovascular exercise for longer periods of time. When using clen, the body does burn protein and fat faster, so users should increase the level of these two macronutrients accordingly. Glycogen levels do remain constant. Clen was originally designed as a bronchial aid, for people with asthma who have trouble breathing. Its useful side effects were quickly discovered. Some users do report irregular heartbeats on this supplement, and it should never be consumed without a doctor’s approval. Clen is accessible via the Internet, but it is not for sale in the US. It is on the banned list for Olympia athletes, and while effective, is often difficult to obtain.
ECA is a daily stack of Aspirin, Caffeine, and Ephedrine. 25 mg ephedrine, 250 mg aspirin, and 300 mg caffeine, taken 1-2 times per day, it has been proven remarkably effective in weight loss by both bodybuilding/fitness athletes, but by everyday people looking to shed a few pounds. Ephedra and caffeine create a synergistic effect in the body, much like Clenbuterol, raising blood pressure to increase oxygen transport in the blood. Users of ECA often experience increased energy levels, fat loss, and increased irritability. In the bodybuilding/fitness world, dieting athletes have used for ECA over a decade, and its reputation is that of a very effective agent.
When all is said and done, ECA is the last man standing. Taking into account its proven track record, the fact that it is legal, and the fact that it is so readily available – not to mention arguably more effective – allows the ECA stack to edge out Clenbuterol as the cutting agent of choice for bodybuilders. Top-level professional bodybuilders often “stack” the two, using ECA and clen together. This is a risky practice, as two agents raising blood pressure at once can cause some serious heart issues. Stick with one, and make that ECA most of the time.
