Is Player Telling The Truth?

Hello. Gary Player caused a stir at the British Open by saying he knew one golfer in particular who was taking supplements. He estimated there were at least 10 players on the PGA Tour doing it, with unknown numbers elsewhere.
Many people thought it was bad for Player to say what he did, because he didn't name names. However, no one said he was out in left field.
Is it true? In an excellent article by Mark Spector of the National Post, he says we can't know for sure because people don't admit to taking drugs. So when a Chris Benoit dies, doctors don't have enough sample cases to determine what effects supplements have on the human body.
Golf is in a unique position to do what baseball should've done - come clean. Let everyone get out in the open what they've taken. Test everyone currently on the PGA Tour to get a baseline, especially with testosterone levels. Then let them play, and test regularly.
Would this effect golf negatively? Short term, yes;long term, no. Golf would be admired for doing the right thing, and being up front and honest. Since this is what golf is known for, it makes sense to do it.
