Arms	Assigned Interventions
1: Active Comparator Low dose testosterone	Drug: Comparator: low dose testosterone Subjects will receive two muscle biopsies, the first at baseline, and the second a week after a single intramuscular dose of 200 mg (0.8 mL) testosterone.
2: Active Comparator High dose testosterone	Drug: Comparator: high dose testosterone Subjects will receive two muscle biopsies, the first at baseline, and the second a week after a single intramuscular dose of 600 mg (2.4 mL) testosterone.
3: Placebo Comparator Placebo	Drug: Comparator: placebo Subjects will receive two muscle biopsies, the first at baseline, and the second a week after a single intramuscular dose of 0.8 mL placebo saline solution.
