History was achieved on September 7, 1998. Cardinal St. Louis's "best batters", Mark Mcguwire, defeated the home run of the season 62, exceeding the legend of Roger Maris for 37 years. Somehow, like most events in the masses' eyes, the controversy surrounding McQuay and his wonderful virtue is becoming a focus of attention. One week before McGwire broke record - breaking home run, he admitted that he was using the testosterone - enhancing supplement and the androstenedione frankly. Since then the dispute over this supplement was exciting.
Androstenedione is one of the leading supplements for fitness nutrition. Many serious bodybuilders also use androstenedione to help further increase the size and strength of slender muscles. Androstenedione helps the body build lean body mass by supplementing testosterone. This 'medicine' helps to achieve what many people are looking for, but pays a price. Androstenedione is also one of the most controversial supplements on the market. It has many side effects and is said to cause cancer. Many people do not realize that the real chemical composition behind this medicine will make it all work.
Androstenedione and DHEA supplementary effects on men Androstenedione is a widely used supplement for bodybuilders and athletes. Dehydroepiandrosterone or dehydroepiandrosterone is a well-known testosterone precursor and is also a special concern as an anti-aging supplement. Both supplements are criticized for their ineffectiveness or lack of evidence. Androstenedione is a natural precursor of testosterone. Adrenal glands and gonads produce androstenedione. In the liver, androstenedione is converted to testosterone and can be returned as necessary (1). The assimilation effect exhibited by testosterone is what the user expects. Androstenedione can also be converted to estrone, the major estrogen (2). This conversion is the cause of many possible adverse effects. The recommended dose of androstenedione is 25 mg to 100 mg per day. Most supplement companies claim that Androstenedione can promote testosterone
Androstenedione is prohormone. It is a small amount of biological substances produced by the adrenal cortex, ovaries and testes in the body. When entering the liver, it is converted to testosterone by the enzyme acting on androstenedione. Transformation produces only testosterone and only one enzyme reaction is required. The content of androstenedione depends on multiplex control of the enzyme. For example, if the luteinizing hormone is low, the production of testosterone is low. After that, it is absorbed by the blood. High testosterone levels are associated with increased lean muscle mass and decreased body fat. Testosterone is produced by collecting nitrogen, an important component of muscle fibers, to promote muscle growth. In a sense, androstenedione can be regarded as anabolic steroid hormone or muscle growth hormone. Synthetic anabolic steroid hormones have dangerous side effects and are illegal for non-medical uses
