Heather Kyros purchased the stallion in 2021, with her daughter Kate taking over riding duties after the World Championships. Together, Kate and Chemistry made a remarkable CDI-U25 Big Tour debut in 2023, achieving 18 CDI class wins across Australia, North America, and Europe. Highlights included winning an FEI Nations Cup gold medal in Wellington, Florida in 2024, multiple CDI3* victories at the Brisbane CDI, and reaching No. 4 in the FEI dressage World Youth Ranking – U25.

Their final competition together was at Deauville, France, in 2023 before the stallion was sold in Europe. Kate expressed deep emotion over the farewell, reflecting on their incredible journey and the bond they shared, calling herself the luckiest to have had the experience with Chemistry.
