The man in the picture looks very strong, with big and protruding muscles, almost worse than the "Wolverine" in the movie, right? But if I tell you for sure that he has taken steroid hormones, it is impossible to build such a large muscle group. Can you believe it?
This is a photo comparison before and after using synthetic steroid drugs:
What exactly is a steroid?
Simply put, steroid is a drug similar to the basic hormone "testosterone" in human body. Testosterone, also known as "testosterone", is an important hormone that makes male signs appear. Many women also actively exercise, but exercise can only make their muscles stronger and more elastic, and will not cause large-scale muscle swelling, just because of the lack of "testosterone." Therefore, girls should not use the excuse that they can practice one track-minded and look too like women to avoid exercise. As long as you don't take steroid injections with them, you can't practice one track mind.
So how do synthetic steroids make these bodybuilders have perfect muscles?
First of all, their molecular structure is similar to "testosterone", so they can combine with the "androgen receptor" structure in cells, and then they can change some behaviors of genes, produce more muscle proteins, form more and larger muscle cells, and make the body mistakenly think that it is going through another adolescence. In this way, the effect of your exercise will be greatly improved and the recovery time of muscle fatigue will be greatly shortened.
A study shows that men who use steroids 10 weeks can gain 2 to 5 kilograms of lean body mass-that is, muscle. The report also said that their strength increased by 5% to 20%. Compared with other parts, the muscle mass of the subjects' chest, shoulders and upper arms increased more. This is because muscle cells in those areas contain more androgen receptors, not because they skip leg training every week. It is also well understood that compared with other forms of weightlifting, steroid users' bench press performance has improved more obviously.
This drug is mostly used in the medical field to treat emaciated cancer patients or AIDS patients and help them recover the weight lost due to the disease. Synthetic steroids are also used to treat some hormone deficiencies.
However, the BBC social survey found that most synthetic steroids are abused in fitness and shaping. This is also the origin of a large number of gym muscles now.
These people usually have amazing muscles. Want to know Bruce Lee's muscle mass is so much, a long time ago, Hercules did not practice the muscle mass of muscular men.
So now many bodybuilders have developed huge tendons. Is it worth it? This is similar to a woman's plastic surgery. Everyone knows that it may do harm to the body, but the benefits are immediate, so there are still many people flocking to it.
What are the hazards of steroids?
Because the body will think that it has experienced another adolescence, the activation of androgen receptors in cells will increase the amount of oil secreted by sebaceous glands, which will lead to acne. Excessive use of synthetic steroids will also make you age faster. Will reduce the number of sperm, resulting in testicular atrophy. Changes in hormone levels may also lead to hair loss, and the risk of cardiovascular disease will increase for both men and women.
So acne and hair loss are the most obvious appearances, so it is not surprising that you have seen men with muscles, many of whom are bald. The guidance of exaggerated images in TV movies will not make you healthier, healthier and gentler.
