Androsterone is a naturally occurring steroid hormone and a key metabolite of testosterone, serving as an important analytical reference standard in chemical, biochemical, and pharmaceutical research. It is utilized in laboratories for the identification, quantification, and study of androgen metabolism, particularly in endocrinology, hormone therapy investigations, and doping control in sports science. With a purity of 99.5%, it meets analytical specifications including appearance as a white to off-white solid, and conformance to structure via infrared spectrum and NMR. While explored for potential influences on libido, energy levels, hormonal balance, and vitality in anti-aging or wellness contexts, its therapeutic applications are limited, and inclusion in supplements requires caution and medical oversight.
