Clenbuterol is the name of the drug that the zero-size diet pill uses to create rapid weight loss. It's made as a medicine to fight asthma in horses, but bodybuilders found that it caused them to lose fat by increasing muscle mass, so it caught the attention of the Hollywood crowd of celebrities who are always on the lookout for the next big thing in weight loss.
The zero-size diet pill increases body temperature by about half a degree and begins to increase metabolic rate soon after taking it. Excess fat calories are inevitably burned as Clenbuterol directly stimulates fat cells. Although the zero-size diet pill begins to work quickly, its effects lessen over the course of 4-6 weeks of constant use as the body gets used to it.
When it comes to agents for a bodybuilding show, I usually only think of two words: ECA and Clen. ECA is an easy and legal weight loss solution used by many beginners and intermediate bodybuilders when preparing for a show. Advanced bodybuilders (top-tier NPCs and professional athletes) often use RCTs in conjunction with Clenbuterol for an incredibly synergistic fat loss effect. Both are options, but Clenbuterol should only be used once the RCT is no longer sufficient to reach body fat levels.
Users of the zero-size diet pill have noticed a number of minor side effects, including insomnia, profuse sweating, poor concentration, and an increase in blood pressure. There are also more serious side effects; permanent deterioration of the liver, heart, and lungs has been observed with long-term use of the drug, significantly increasing the chances of heart attack and other cardiovascular problems.
Clen was originally designed for the treatment of lung diseases, including asthma. Athletes soon discovered that simply taking it to the bigger muscles and lower body fat. Scientifically, Clen uses oxygen in the bloodstream more efficiently. In life terms for bodybuilders, this translates to decreased muscle atrophy, increased body, and faster burning of stored body fat. Clen is a favorite top amateur bodybuilder and is used to some extent by most professional bodybuilders before a show, usually stacked with the ECA.
Risk and reward
Clenbuterol is a very anabolic medication. Its positive effects are felt immediately, which means that the basis of the side affects also starts almost immediately. In the short term, the user may feel overheated, nauseated, shaky, and anxious. The long-term side effects of clen use mainly include arrhythmia, heart failure, and heart damage. It makes the system move faster, and the heart is definitely part of the system. Clen should never be taken year-round. Bodybuilders should only consider cleanings 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 program, you're probably not in a position to be ready for Clenbuterol. ECA is definitely the compound you should be using right now. As your competition nears 220 body weights (over 240 off-season) and has peaked in four or more shows, it might be time to add Clen to your pre-season regimen.
