In most cases every drug under each category listed above can be obtained legally with a prescription, however most are illegal to use without a prescription and banned from use by most sporting associations. Depending on the organization in-which you compete the level of enforcement of the rule will vary but an interesting note, the majority of people who use performance enhancing drugs do not partake in any organized sporting competition but do so only to look better than they would otherwise. Unfortunately for these individuals, most of them do so by breaking the law but this legal factor does not seem to be slowing down the use by any means.
