GONAbreed^®: High-concentration GnRH for confident efficiency in every dose

GONAbreed^® (gonadorelin acetate) is a high-concentration GnRH product designed to treat cystic ovaries and support estrous synchronization in cattle. Paired with estroPLAN^®, it enables producers and veterinarians to effectively implement timed artificial insemination (TAI) across a wide range of cow and heifer protocols. With the highest GnRH concentration available in a 1 mL dose, GONAbreed® increases efficiency by minimizing vial changes—streamlining reproductive management at scale.

GONAbreed® is supported by our "Beyond the Bottle" approach—featuring the mySYNCH^™ Platform and mySYNCH^™ Services, including Repro Reviews and on-farm Compliance Training. This combination empowers producers and veterinarians to boost protocol compliance, gain actionable herd insights, and make confident, data-driven reproductive decisions.
