METHITEST™ (methyltestosterone) tablets, USP are to be taken orally. Androgens are derivatives of cyclopentanoperhydrophenanthrena. Endogenous androgens are C-19 steroids with a side chain at C-17, and with two angular methyl groups. Testosterone is the primary endogenous androgen. In their active form, all drugs in the class have a 17-beta-hydroxy group. 17-alpha alkylation (methyltestosterone) increases the pharmacologic activity per unit weight compared to testosterone when given orally. Methyltestosterone is the 17α-methyl derivative of testosterone, the true testicular hormone. Chemically, methyltestosterone is 17b-hydroxy-17-methylandrost-4-en-3-one, with the empirical formula C 20 H 30 O 2 , a molecular weight of 302.5, and the following structural formula: C 20 H 30 O 2 M.W. 302.46 (CAS-58-18-4) 17 β-Hydroxy-17-methylandrost-4-en-3-one Methyltestosterone, USP is a white to creamy-white, odorless, slightly hydroscopic powder.
