General description

This Certified Spiking Solution^® is suitable for GC/MS and LC/MS applications from clinical and diagnostic testing and endocrinology to sports testing.5α-Dihydrotestosterone (DHT) is a steroid hormone and metabolite of the natural androgen, testosterone, formed by the action of NADPH-dependent enzyme 5α-reductase. It has been implicated in a broad range of diseases from male pattern baldness to benign prostatic hyperplasia and prostate cancer. As an anabolic steroid, DHT has also been used as a performance-enhancing drug to promote muscle growth.
