[Source] The Cyduct E-23 Booster was a interdermal injection system manufactured by Selesin Medicinal Electronics. It facilitated the application of chemical boosters or other medication inconspicuously. The chemical booster could be worn on the wrist or shoulder strap and used a system of micro-sonic vibration injectors to deliver the desired chemicals directly through the skin without pain or leaving a mark. The system could also be configured for continuous feed or time release application. A number of serums were available for use with the Cyduct E-23 Booster.
