A method for the use of derivatives of hydroxypregnenolone (3-beta,17-alpha-dihydroxypregn-5-en-3-one) to enhance health and physical performance in humans and more particularly to the use of hydroxypregnenolone derivatives for restoring renal hormonal balance, decreasing body weight, reducing adipose tissue, increasing endurance, promoting skeletal muscle growth, boosting androgen levels, inhibiting aromatase, and increasing cognitive function.

conditions, were used together to determine the structure of the D-ring and the sidechain of 20-oxo and 20-hydroxy pregnane(ene)s without oxo groups on the A-, B-, and C-ring. All possible combinations of D-ring and sidechain configuration were considered. Most fragmentations could be interpreted as partial or complete D-ring cleavages with loss of the sidechain, aided by comparison with spectra of deuterated
