NEED INFO ON SYD PILL

[En_on_X]

I have just got my hands on a small white pill a little smaller than most. It has a score on one side and the word YES on the other.
Has anyone else had these or have tested them/i have no tester.

Have heard them touted as Optus "YES". Dont have any specific info or test results...but meant to come from good source.
