Thyroxine is used to treat insulin resistance. Using it as a weight loss drug may be legal but ethical? Guess it all depends on your point of view.

Regular (non racehorses) horses that are overweight and show signs of cushings or laminitis are also often given thyroxine to help control their weight. I have a IR horse that gets special feed and has been prescribed thyroxine. Literally thousands of vets prescribe thyroxine as a weight control tool.
