I'm only 63 but I've used dexamethasone as needed when I get lame and can't go because of my back for 20+ years. I've heard dex is hard on your liver but I get my blood checked twice a year because I take ibuprofen 800 on a regular basis. If it's good enough for an animal it's good enough for me. I don't recommend anyone giving themselves a shot of LA 300, but it works also.
