As for the term anabolism, I believe that the general public who are not majoring in biology are still very strange before they come into contact with fitness. Relative to the concept of anabolism, the public should be exposed to the term "metabolism" at the earliest.

Metabolism refers to the process of material and energy exchange and self-renewal between organisms and their internal environment, including anabolism (assimilation) and catabolism (alienation). Synthetic metabolism refers to the changing process in which organisms convert nutrients obtained from the external environment into their own components and store energy. Our muscle growth occurs in the process of anabolism, and we often say that losing muscle is due to the catabolism of the body. The word anabolism is explained by biology: biosynthesis produces substances with larger molecules and more complex structures, which requires the consumption of free energy, which is usually directly provided by adenosine triphosphate (ATP).

Anabolic and catabolic are two aspects of the metabolic process, which are carried out simultaneously. ATP produced by catabolism can be used for anabolism, and the building blocks of anabolism often come from the intermediate products of catabolism. Contrary to catabolism, anabolism is the synthesis of various biological macromolecules from several structural units. In short, it is the process of our muscle synthesis. In the field of bodybuilding, anabolism usually refers to anabolic steroids.

Why should I emphasize the concept of anabolism here? After being exposed to anabolic drugs, most novice Xiao Bai has a wrong understanding of anabolic drugs and ignores the "synthetic substitutes" of the mechanism of action brought by these drugs.

Sweating in the gym every day destroys muscle fibers, and taking protein, carbohydrates, vitamins and various amino acid supplements every day to form good living habits, going to bed early and getting up early, not drinking, not eating indiscriminately and not missing food. What is the essence of all this? It is to create the best anabolic environment for muscle growth for our body. Adequate nutrient intake ensures that your muscles have enough raw materials for growth. The habit of going to bed early and getting up early, and all kinds of sweating training stimuli cause a series of coherent reactions of hormone secretion in your body, from the secretion of growth factors that destroy muscle fibers to insulin in the eating stage, growth hormones in the sleeping stage, and protein assimilation in the repair stage. From the time you enter the gym until you fall asleep every night, your body triggers a series of reactions through your external influence. Everything you do is to create an optimal anabolic environment for your body and let your body grow more muscles in the best condition. The muscle injury caused by sweat resistance training in the gym will release inflammatory molecules called cellular molecules to activate the immune system, repair the injury (the participation of endocrine hormones), and make our muscles bigger and stronger to meet the sports needs of the body.

The demand of muscle growth: external stimulation+nutritional support+endocrine hormone support, everything we do is to create a better anabolic environment for the body as much as possible.

Compared with other competitive sports, the drugs used by bodybuilders have considerable limitations, because the essential definition of bodybuilding makes him different from other antagonistic competitive sports. Essentially, it is an ornamental sport, so the stimulants used by bodybuilders can only focus on the essence of the sport: muscles, so all stimulants used are for muscle growth. Or the visual effect of physical state on the field is better. There are many white people commenting on bodybuilders' use of drugs on the Internet, but in fact, all competitive sports involve stimulants, and even some you can't think of ... such as chess, so I won't elaborate here. Weightlifters don't need to run faster, and track and field athletes don't need endless strength. Bodybuilding is an ornamental sport, and all stimulants used by bodybuilders will be displayed on the body. 50+ arms can always give ordinary people visual education, and the performance on the stage is so horrible that people have to think of stimulants and drugs behind them. Even though bodybuilding is closely related to anabolic drugs, all bodybuilders are the king of medicine. Of course, I'm talking about a real bodybuilder, not a fitness enthusiast who thinks he is a bodybuilder without appreciation, that is, to make everyone king, but bodybuilding is still not the hardest hit in the field of doping use.

? And there are still many things that have not been found out. Hehe, compared with other sports, the stimulants used in fitness are mostly steroids and peptide hormones. These elutriation products (all played badly by others in the last century) are accurate, which means that Ke Ben can't escape drug testing, while most other sports involve politics. Most of the drugs used are modified and customized by specialized laboratories and personnel. If you find out, you are a bear. If you don't find out, you are a hero. )

That's all the nonsense above, even slightly off topic. To sum up, the use of various anabolic drugs, such as anabolic steroids, growth hormones, insulin and other exogenous hormones, causes the crazy growth of muscles, not the drugs themselves, but the drugs completely break the anabolic environment of your body, which is a height that you will never reach in the natural environment. As mentioned above, the stimulants used in bodybuilding are very limited and can be roughly divided into several categories. Metabolic steroids, growth hormone, insulin and other exogenous sex hormones, as well as hormone receptor modulators such as SARMS such as MK-677, GW50 15 16 and SERMS such as tamoxifen, and hormone inhibitors such as GDF- 8. ACE03 1, which has a negative effect on muscle growth by inhibiting human body, is also a small amount of fillers (similar to female breast enhancement), such as the famous Sislong, and the temporary Esiclene (the swelling of the injection site after injection causes temporary dimensional growth, which will disappear after a period of time, and also belongs to steroid hormones, strictly speaking, it is not a filler). When we choose to pick up the syringe and inject a lot of exogenous hormones into the body, our anabolic environment will change greatly. The hormone in the syringe is the height that our own secretion can never reach (the normal human body can secrete testosterone in the range of 4-9 mg per day). For example, the protein you eat every day is the raw material for building a house, so the hormones in your body are the workers who build a house. The essence of using anabolic drugs is to increase the number of workers, so as to achieve the purpose of building houses.

At this time, people who may be curious have another question. According to my analogy just now, the use of anabolic drugs in building houses can increase the number of workers. Then, even without using exogenous hormones, can we reach the level of modern bodybuilders according to human hormones? It's just that time is slow. This is a big mistake. I just talked about anabolism, but our human body is actually undergoing anabolism and catabolism at the same time. You are losing muscle while growing muscle. You can also understand that anabolism and catabolism interact, so it is so difficult for us to gain weight in the natural state. While you are helping yourself to grow muscles, your body is also decomposing itself at the same time. Using anabolic steroids, growth hormones and other anabolic drugs will not only improve our anabolic effect, but also inhibit our own catabolic effect, thus causing the crazy growth of muscles.
