Actually works!
I am always looking for additional ways to support my UL event horse. I thought Flexsyn would be worth trying and I liked how it wouldn't involve any more needles (on top of injectables like Legend, Adequan, Zycosan, etc). I was honestly surprised at how noticable of a difference it made in just one dose (imo more so than any of the injectables I (still) use). I have been using it before events for a couple years now and have been happy with the results!
