The routine doping tests were performed in March.
In a news release, the Canadian Centre for Ethics in Sport (CCES) confirmed four of those athletes play football for Saint Mary's University in Halifax and three of them have been sanctioned for a period of four years.
CIS has imposed four-year sanctions against:- Kayin Marchand-Wright, SMU football player, tested positive for selective androgen receptor modulator (SARM-22).
- Melvin Abankwah, SMU football player, tested positive for methandienone.
- Jonathan Langa, SMU football player, tested positive for methandienone and stanozolol.
- Matthew Norzil, Université Laval, tested positive for SARM-22.
A fourth SMU athlete, Marvin-James Golding tested positive for SARM-22, anabolic agents similar to steroids, but his case remains open and he has the right to pursue a hearing.
According to its website, the CCES is an independent, national, not-for profit organization, which publicly announces every anti-doping rule violation.
