The effects of Androstenedione vs. DHEA supplementation in men. Androstenedione is a popular and widely used supplement among body builders and athletes. Dehydroepiandrosterone or DHEA is a wellknown precursor to testosterone, as well as a special interest as an anti aging supplement. Both supplements have been criticized for their ineffectiveness or lack of proof. Androstenedione has become extremely popular since, once home run, king Mark Mc Gwire admitted to using it during his extremely popular home run race in 1998. The NFL, the International Olymipic Committee and NHL have banned the use of it. Androstenedione is a natural precursor to testosterone. The adrenal glands and gonads produce Androstenedione. In the liver Androstenedione can be converted to testosterone and back depending on the need (1). The anabolic effects that testosterone displays are what is desired by users. Androstenedione can also be converted to estrone, a predominantely female hormone (2). This conversion is responsible for many of the possible negative side effects. The recommended dosage of androstenedione is 25mg to 100mg daily. Most supplement companies have made claims that androstenedione can boost testosterone. There have been no
Many of them are conducting their own studies and publishing different results than the previous tests. Many call DHEA the fountain of youth pill. Most of these benefits seem only to be noticeable in older men because eof their decreased DHEA levels. Androstenedione and DHEA supplementation have both shown to be ineffective in the enhancement of sports performance for men. There was also no significant changes in hormone levels between baseline or placebo (15). On the second day they performed resistance exercises. They don't have any quality control to meet nor do they have to guarantee any purity or amounts in the products. The evidence leads us to believe that androstenedione is a useless supplement. Also an 83% increase in estradiol was found in the supplemented group (3). It is made in the adrenal cortex (7). DHEA supplementation has been proven to be effective in aspects of human health other than bodybuilding. Many manufacturers of androstenedione do not accept these tests as real proof to the ineffectiveness of their product. Also no differences were noted in body composition. The test subjects had at least one year training experience and were told to continue their training routines. Subjects continued their regular exercise routines.
