Testosterone undecanoate is a white to off-white yellow crystalline powder. Testosterone, an androgen, is formed by cleavage of the ester side chain of testosterone undecanoate. Testosterone undecanoate is chemically described as 17β-hydroxyandrost-4-en-3-one undecanoate. It has the empirical formula of C 30 H 48 O 3 and the molecular weight of 456.7. The structural formula for testosterone undecanoate is presented in Figure 1. Figure 1: Testosterone Undecanoate JATENZO capsules are available in three strengths of 158 mg, 198 mg, and 237 mg.
