pro-level athletes are neither common nor cheap
Under the let-the-better-potion-win system what makes you pro-level is that you work with a good lab which makes effective potions. The incentives for second and lower-tier athletes are to get to the bleeding edge and push -- that's the only way for them to get to top tier. I doubt there will be a lack of willing test subjects.
It's probably still better to just ban the doping from human sports and allow them in, say, pig races.
“It cannot be gotten for gold, neither shall silver be weighed for the price thereof. / It cannot be valued with the gold of Ophir, with the precious onyx, nor the sapphire. / The gold and the crystal cannot equal it: and the exchange of it shall not be for vessels of fine gold. / No mention shall be made of coral, or of pearls: for the price of wisdom is above rubies.”
