Buy a test kit and find out what it is, talk to Sym and see what they have to say, if what you were sent does not match the listing of what you ordered take it to resolution and ask for a refund. If you have finalized then pursue that ooe with Sym. I would urge against passing it on until you know at least what the fuck it is because by the sounds of it no one has any idea at this point in time beyond speculating it could be all manner of things so I'd like to know what I was selling to people to ingest but that's just me.
