TRS / Sex Hormone Test and Syringe for Trans People


TRS is the first sex hormones self-testing and intramuscular self-injecting device specifically designed for transgender people who require taking lifelong hormone replacement therapy. TRS enables users to test their sex hormones by urine regularly at home, analyzes the optimal injection cycle, and reminds users of each injection date through App and the indicator lights. Made of degradable materials, TRS is designed to be highly intuitive, comfortable and safe for self-injection, helping users stabilize their sex hormones at the correct levels, thereby minimizing the risk of physical illness.
