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 some 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 exercises for longer periods of time. When using clean, the body does burn protein and fat faster, so users should increase the level of these two macronutrients accordingly. Glycogen levels do remain constant.
Clenbuterol was originally designed as a bronchial aid, for people with asthma who have trouble breathing. It’s 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.
Clenbuterol was at the beginning designed for treatment of lung ailments, including asthma. Athletes soon discovered that taking it led to bigger muscles and lower body fat, simply put. Scientifically, Clen makes the use of oxygen in the bloodstream more efficient. In real life terms for bodybuilders, this translates to lessened muscle atrophy, greater body mass, and faster burning of stored body fat. Clen is a favorite among top amateur bodybuilders, and the majority of professional bodybuilders to employ it to some degree leading up to a show, typically stacked with ECA.
Risk & Reward
Clenbuterol is a very anabolic drug. Its positive effects are felt almost immediately, which means that the foundation for side effects begin almost immediately as well. Short term, the user may feel overheated, nauseous, shaky, and anxious. The longer term side effects of Clen use primarily include heart arrhythmia, heart failure, and heart damage. It makes the system move faster, and the heart is part of the system. Clenbuterol should never be taken year-round. Bodybuilders should only consider it for short-term use, to lose body fat immediately before a show.
If you’re new to bodybuilding or competing in a local NPC level show, you are probably not in a position to be ready for Clenbuterol. ECA is the compound you should be utilizing at this time. As your competition bodyweight approaches 220 (240+ off-season) and you’ve peaked for four or more shows, it might be time to add Clen to your pre-season regimen.
