Has anyone ever tried SmartHA Plus Gel?

The 3 and 4 day shows are tough on my mare’s joints, I do everything I can to keep her comfortable (bringing stall mats for the cement stalls, bedding really deep, standing wraps in the stall, poultice at night, cold hosing, liniment and lots of long walks to stretch throughout the day etc.) I’ve pretty much got the routine down that keeps her comfy and happy but am always looking to improve and was thinking about giving this a try – maybe a dose before the show, a dose during and a dose after? Has anyone ever tried the product? I’m not expecting a miracle but after reading some of the reviews I am curious about it and just wanted to see if anyone on here had any personal experience with it! Thanks in Advance!
