Doah Pharmaceutical's energy drink 'Eul Doctor' has unveiled a new advertisement campaign featuring TVXQ's Yunho, SHINee's Minho, and RIIZE's Eunseok and Wonbin as models. Announced on January 1, 2024, this campaign is characterized by a 'legendary lineup' created by mixing members from different SM Entertainment groups. Doah Pharmaceutical stated that it projected the 'optimal combination' concept of the modisumer product 'Eul Doctor' into the model composition to maximize brand identity. The new advertisement features powerful directing, with the background music being a remake of Deus' signature song 'We Are' adapted to appeal to younger generations. All four models participated directly in voice recording and showcased dynamic dance performances to sensually express the product's refreshing image. 'Eul Doctor' contains 1500mg of taurine and three types of vitamin B complex. Since its launch, it has surpassed 35 million units sold within one year, establishing itself as an emerging force in the energy drink market. Going forward, Doah Pharmaceutical plans to segment its target audience by age group, with differentiated communication strategies for teens ('Park Flavor'), adults in their 20s-30s ('Eul Doctor'), and Generation X ('Bacchus').
