LP14045-6   Testosterone
Testosterone is an androgenic steroid and is the primary male sex hormone. Approximately half of circulating testosterone is tightly bound to a protein called sex hormone binding globulin (SHBG) and is biologically inactive. Another fraction is weakly bound to other proteins, such as albumin, and the remainder is unbound, or "free". Weakly bound and free testosterone together represent bioavailable testosterone. Both total and free testosterone levels decrease with age. Low testosterone is associated with many other conditions, including osteoporosis, Alzheimer's disease, obesity, diabetes and ischemic heart disease.

LP14045-6   Testosterone
A potent androgenic steroid and major product secreted by the Leydig cells of the testis. Its production is stimulated by luteinizing hormone from the pituitary gland. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to dihydrotestosterone or estradiol.

LP32047-0   Epitestosterone
Epitestosterone is a natural steroid, an inactive epimer of the hormone testosterone. Epitestosterone is believed to form in a similar way to testosterone; a 1993 study found that around 50% of epitestosterone production in human males can be ascribed to the testis , although the exact pathway of its formation is still the subject of research. It has been shown to accumulate in mammary cyst fluid and in the prostate. Epitestosterone levels are typically highest in young males; however, by adulthood, most healthy males exhibit a testosterone to epitestosterone ratio (TE ratio) of about 1:1. Epistestosterone and testosterone:It has been shown that exogenous administration of testosterone does not affect levels of epitestosterone in the body. As a result, tests to determine the ratio of testosterone to epitestosterone in urine are used to find athletes who are doping.
