I have been using Adequan on my gelding for ring bone for 12 years and he is perfectly wound. Also use it on horses that are in the late 20's to keep them comfortable. Excellent Product.

Owner MT Chrome Appaloosas


Adequan has worked in cases of upper ringbone and several of our older horses. I highly recommend it. By giving an injection nothing is waisted and your horse receives all of the benefits.

A must for performance horses!


I start all my performance horses on this when they begin work and keep them on it for their entire working life. I am able to reduce how soon horses require joint injections as well as the frequency with Adequan.

A must have for working and older horses


I've been using this for years on all my horses as stated in a previous review. I've experienced great results by giving a yearly loading dose (1 dose given every 4 days x7), then monthly year round. FarmVet offers nice coupon offers throughout the year on this product!
