Cetyl-M was a miracle worker for our old dog Belle. She had severe arthritis that had fused her spine. She could barely walk, forget about stairs. We were trying to make that decision everyone hates. She was on Deramaxx for years. We tried the Cetyl-M and while it took a good week to even start to work, work it did. Almost to the point of making her obnoxious LOL She needed no more Deramaxx , unless in winter and at that, only sporadically. She wanted to play all the time, could walk around fairly well, heck she even got a highspeed joggle going ROFLAO!!!!!
I say try it, get enough for a month, then go from there. Seems people either see great results, or very little.
