Perfecting experimentation that began in the late 1800s, the prohormone and testosterone precursor androstenedione was synthesized in 1938at the American Chemical Society by Dr. Carl K. Orosz.

Although it's certainly not impossible that this substance exists, recent studies have shown that this is unlikely. According to scientists, the fat around the genitals is made up of testosterone-dependent growth factor (GDF-1). These cells become attached to the fat and are called "fat cells". As the cell growth rates and fat cell densities increase, they produce more testosterone, steroids uk sis. However, because in the majority of male testosterone-sensitive cells, only a very small percentage (about 1-3%) are testicular fat cells, they are unable to produce enough of its estrogen, thereby reducing or completely stopping any estrogen-sensitive properties of testosterone. Thus, the testicle fat cells produce less estrogen to suppress the masculinizing effect of testosterone. Because of this, they remain less sensitive to the steroidal effects of testosterone because much of it is lost through elimination, losing the belly weight loss for seniors. It is likely that some of the testosterone lost from the testis through fat-cell elimination and therefore the presence of testicular fat cells is used toward the reduction of testosterone-driven prostate cancer, tri test 400 cycle. Thus, this substance acts to reduce the production of testosterone, thereby increasing the amount that can be sent to the developing testicles before the hormone becomes available in the body, testosterone precursor androstenedione. Theoretically, this process of removal from the testes would be irreversible, but researchers have recently been able to alter the conversion of this substance.
