Osatrine is a SARM, there's many supplements that get contaminated with them, Ostarine probably being one of the main ones.
The link the poster shared touched on it;
""The US Anti-Doping Agency’s (USADA) Supplement 411 resource lists over 200 supplements that contain SARMs; 98 that specifically contain Ostarine; and nine that specifically contain S-23. In 2017, USADA issued a warning about Ostarine in supplements that it updated in 2019. This specified that there are 72 products on USADA’s High Risk List that contain Ostarine, including 19 where it isn’t declared on the label.""
