Important points here. As a masters runner I am regularly competing against "pharmaceutically aided" athletes.
1. People who rail against "dopers" but could not train, let along race, without their cocktail of statin, antihypertensive, anti-inflammatories etc, and who regard themselves as healthy despite their reliance on prescription meds. Most masters competitors, especially in the US, seem to subscribe to the idea that taking prescription meds is a normal part of ageing.
"Nearly 70 percent of Americans are on at least one prescription drug, and more than half take two, Mayo Clinic and Olmsted Medical Center researchers say" (2013 stat).
All these meds are performance-enhancing, even if they are not categorised as such by WADA.
2. People who are on testosterone "replacement" and regard that as life-saving, or at the very least life-extending, and know they can get away with it because they are never going to be tested. And
3. People with TUEs for performance-enhancing drugs.
I should have the right to know who I'm competing against, so anyone who is awarded a TUE should be identified as such with as asterisk by their name on entry lists and in results. Keep confidentially - I don't need to know what the drug is or why they are allowed it, but I think it would be fair to know that they are competing with a TUE.
