UN-LOCK® is an advanced muscle formula for muscle support in horses. "Tying up,” or exertional rhabdomyolysis, refers to muscle stiffness and pain after exercise. It can occur sporadically or chronically. The ingredients in UN-LOCK include Arginine, selenium and Vitamin C, which have been shown in clinical studies to prevent tying up during intense exercise or competitions.


When we were formulating UN-LOCK, we made sure to include only proven nutrients to improve performance, prevent cramping and tying up, maintain top speeds and improve recovery.* When this happens, horses obtain dramatic gains in endurance and performance.*

What Makes UN-Lock different?

You'll notice the difference the first time you use UN-LOCK as results are immediate. UN-LOCK contains more amino acids, electrolytes, and essential vitamins than any formula on the market!

What should I expect with UN-Lock?

You should expect a horse that travels, trains and competes to have a noticable improvement in performance and recovery with first use. Less than an hour after administration, you can expect to see a more alert and energetic horse with the ability to maintain top speed longer.*

Reviews from TOP Trainers and Owners

“When horses are tying up during training, they remember what they were doing when it happened and resist activities that made it happen. Using UN-LOCK on a regular basis prevents that problem in the future. I highly recommend this. — Webb Carroll, Webb Carroll Training Center

"We gave our horse a tube of UN-LOCK before and after a 10-hour drive to the track, and again a few hours before the race. He came from the back of the field to winning at the end by 10 meters. The product works"*

Rickie Alchin, Rickie Alchin Harness Racing

”UN-LOCK is my new favorite product for training and shipping our horses. Love it.”*

Trond Smedshammer, American Viking Stables (1,100 career wins; nearly $45M in purses)

“UN-LOCK produced significantly different results than a similar product I tried eight weeks ago: two of my horses finished the race strong and ran very well. One of them lost their last race. Now, after using UN-LOCK, she won by two lengths. I had an older horse that was flat and not finishing well. With UN-LOCK that horse not only finished well but moved up in class with the best speed rating she has ever had.”*

Ray Trisler, multiple stakes winning owner

“My filly had never tied up in her life; Saturday she did. On Sunday I gave her UN-LOCK and she trained beautifully, back to normal. I highly recommend UN-LOCK”*

Michael Aro, trainer of "Winning Image," multiple stakes winning mare

“If you want a stress-free horse for training or transport, try UN-LOCK”*
