I have been using In-Sync for 60 days. I got a new horse whose body condition was less than ideal and I wanted to help her get that healthy "glow." My vet has seen her several times throughout the last 60 days and agrees her condition has improved greatly. Her coat looks healthy and she's packed on a ton of muscle in her shoulders and top line. I'm definitely sold on this product.

I have been using this product for a very short time and have already noticed a difference in my horses topline. My horse licks her bucket clean so that is a plus. So far I'm loving the results!

I started this supplement about a month ago. A friend was buying it and when her horse was put down she gave me what she had left. I put my 24 year old with cushings on it and have already noticed a huge difference in his body condition. His muscles atrophy quickly and he can't handle any type of work beyond a walk, so keeping him from "wasting away" has been a challenge. I've noticed that he has gained a bit of muscle on the top of his butt and his topline has filled in just a bit. I'll definitely be adding this to my arsenal of MVP supplements I feed all my horses.

I have seen a major change in all of my barrel horses since being on this supplement. Their topline looks so much better and their overall physique has improved! Hair coat is shiny and they feel better than ever when riding! My one mare went from middle of the 4D to top half of the 3D in the first week of feeding this supplement!

I started using this product several months ago (currently on my third round of purchasing the 4lb foil bag) and I have noticed significant results. My young gelding had problems keeping his hip from popping out during intensive exercises and this product has helped build his topline. I contribute my not needing to visit the Equine Chiropractor as much to In-Sync, which has saved me a few bills! I would certainly recommend this product if your having difficulty keeping lean muscles on your horse.

Really helped with performance of our 18 y/o in barrels, poles , and roping. Added muscle to his top line. He's running with and winning against younger barrel horses.

I started using this product on my 19yo barrel horse mainly to help increase her top line as well as overall body condition. Within just a couple weeks I've noticed improvements in both. I can already tell that she not only looks better but feels better! Her top line has almost completely built back up. I recently hauled her to a race and I got many compliments on how good she looked! This product is now a must have in my feeding regiment.
