In September 2015 the Agenţia Naţională Anti-Doping (ANAD), the National Anti-Doping Agency of Romania, has reported an anti-doping rule violation against the Athlete Sergiu Giantau after his sample tested positive for the prohibited substance drostanolone.
After notification a provisional suspension was ordered. The Athlete requested for a hearing but he failed to attend the ANAD hearing nor did he file a statement in his defence.
On 20 October 2015 the ANAD Hearing Commission decides to impose a 4 year period of ineligibility on the Athlete starting on the date of the provisional suspension, i.e. on 29 September 2015.
