| Estrone can be formed from estradiol, but its major precursor is androstenedione. |
| In one study, coral homogenates metabolized estradiol into estrone and testosterone into androstenedione and androstanedione. |
| Examples of ergogenic aids are creatine, androstenedione, anabolic steroids, major pain medication, barbiturates, and amphetamines. |
| Estrogen levels elevate due to the peripheral aromatization of androstenedione. |
| Athletes who take the sports supplement androstenedione, commonly known as andro, might want to pay attention to one new finding: the substance can make them fail urine tests for the banned anabolic steroid nandrolone. |
| Androgenic products, namely androstenedione, are testosterone precursors, and transform to this hormone in the body. |
