IWF reports that the sample of Ms. Yenny SINISTERRA (COL) has returned an Adverse Analytical Finding for Boldenone and metabolite (S1.1 Anabolic Androgenic Steroids).

As a consequence, the Athlete is provisionally suspended in view of a potential anti-doping rule violation.

In any case where it is determined that the Athlete did not commit an anti-doping rule violation, the relevant decision will also be published.

IWF will not make any further comments on the case until it is closed.
