I had been a big fan of the JWH series, so I ordered 10 grams of the replacement 5FUR-144 after this years ban on synthetic cannabinoids. What I got COD was a light-resistant baggie of pure white powder, which looked the same as the JWH I used to get.

Summary
XLR-11 is a synthetic indole-derived cannabinoid, one of a class of tetramethylcyclopropyl ketone indoles. It emerged on the recreational drug market as a newer compound after earlier synthetic cannabinoids such as the naphthoylindoles were legally banned. Like related synthetic cannabinoids, it is used recreationally and continues to be abused despite its adverse consequences.
