Regardless of your opinion on the effectiveness of the drug, it’s on the banned list for a reason. It’s obviously been analyzed and proven to provide enough material benefit to make it to the list. If you’re an athlete at the level where you know you will be tested, you should be thinking twice/verifying ANY substance that your doctor prescribes you. It’s not your doctors responsibility to know what you’re up to in your life and tell you that certain drugs/prescriptions could ban you from competition. And it’s obviously not your job to know every substance on the banned list off by heart and be able to recognize it when a doctor prescribes it. But if you are prescribed something, anything, then it’s your responsibility as an athlete make sure what you’re taking is legal from a competitive standpoint.
