About
At Stress Line, we believe the best-performing horses start with a healthy, pain-free body.
We’re a family-built brand, rooted in over 40 years of hands-on experience in equine performance, training, and care. Every formula we offer was developed by C.L. “Butch” Mayhugh, designed to solve real problems seen in the arena, on the trail, and in everyday training.
Our approach is simple:
- No shortcuts
- No unnecessary additives
- No guesswork
Just effective, natural solutions that help horses feel better, move better, and perform at their highest level.
From soreness and inflammation to stress and recovery, Stress Line products are made to support the entire horse — before, during, and after performance.
Whether you're competing at a high level or simply want your horse feeling its best, we’re here to give you a safe, proven edge.
Real results. Real horses. Real people behind it.
