Clomid

Why is Clomid useful for endurance athletes? Am I to understand this is a substance not a the ‘banned list’ and isn’t available at the suppliment store? Is Tribex useful for an endurance athlete?

Clomid is useful to the endurance athlete both because it is typically effective with them in improving their usually-low testosterone levels, and also because it acts at muscle cells to make them more resistant to exercise-induced damage. Last I heard, it was not banned by the IOC, but it is a pharmaceutical drug and is not available at the supplement store, but only at your friendly black-market steroid dealer, or your less-friendly local pharmacist, who will demand a prescription.
