Stability Acid Sensitive Applications 17β-(Trimethylsiloxy)testosterone is an anabolic steriod, and a derivative compound of Testosterone (T155000), Principal hormone of the testes, produced by the interstitial cells. Major circulating androgen; converted by 5α-reductase in androgen-dependent target tissues to 5α-dehydrotestosterone which is required for normal male sexual differentiation. Also converted by aromatization to Estradiol.Testerone is a controlled substance (anabolic steroid). Androgen. References McFarland, K., et al.: Science, 245, 494 (1989), Heckert, L., et al.: Mol.
