I have no idea what "xtreme" or "extreme" is, but it sounds sort of like a branded RC/bath salt/plant food type thing.
We don't do substance IDs here because it's just speculation (we don't even know what you're talking about - so how could we ID the substance?).
Taking a branded RC isn't a safe idea anyway, because putting something random that you don't know what the active chemical in it is into your body is a bad idea.
