Welcome to bluelight. Unfortunately we can do nothing more than speculate, the only way to be sure of what you have is to send it off for testing. You may want to read over the BLUA as this type of thread is not permited.
Branded legal high's are notorious for being complete shit or utterly dangerous for the very reasons you made this thread. You can't know what you're getting without a GC/MS test. Even if you get it tested there is no way to ensure you're getting the same product from batch to batch. I'd highly recommend tossing it.
