I was skeptical but it helped our 20+ year old pony. It only took a couple of weeks and we could tell he was moving easier and with less pain. Be consistent, give it a little time and it should help. He's not galloping, but clearly moves better :)

I had an old quarter horse (late 20s/ early 30s) whose last few years were improved spectacularly by this product. He was retired and lived his life outside with a stall for nights. He started having issues getting up after he rolled and would walk very stiffly in the mornings (many discussions of putting him down prior to winter occurred). After a few weeks of using this product he was acting like young colt bolting out into the fields in the morning, bucking and playing with the others, dropping in the snow for a good roll and getting right back up to run again! He passed in his own time when his heart failed him, but this product helped give him his life back. I had a rescued Percheron with an old leg injury that caused her to walk very stiffly. I added this to her regiment (along with a ton of vet care) and she was actually running around within 2 weeks as well. It was amazing seeing her buck and play with the rest of the gang when she had been in so much pain only a few weeks beforehand. This is truly a miracle product (give it the 15 days, you will see what I mean).

I have two barrel horses. My main barrel horse is an Appendix at the age of 18; he has had many years under saddle: racing, dressage, eventing, and lastly barrel racing. I bought him when he turned 15 as a barrel horse and he hasn't ever responded to joint supplements quite like this one. He was a consistent 3D/4D horse over the years, but I took him to NBHA Youth Worlds last week and he ran in the 2D against some of the best horses in the world! This was just after having him on the supplement for 3 weeks. My other barrel horse is in her twenties and has been running like a 2 year old again! I will never use a different joint supplement again, this has become my go-to in such a short period of time.

I have three horses on RapidFlex, ages 10-24! The older horse had colic surgery and his return to work has been amazing with RapidFlex. The stall rest was hard but hand walking and keeping his joints lubricated were key. The taste is great too. We used RapidFlex to mask some of the medicine he had to take. He loves it!
