The band Testosteron, also known as Te100steron, was founded in 2013 by brothers Andrey and Valeri Birbichadze. They were born in Alma-Ata, Kazakhstan, but later moved to Kaliningrad and then to Moscow. Having been passionate about music since childhood, the brothers decided to form a musical group, which led to the recording of their first track “Missing You”, which quickly gained popularity on the radio. In 2021, the band received a platinum record for their song “This Ain't No Woman,” which reached over 250 million streams and downloads. The band was also nominated for the RU.TV award in the Best Start category.
