What ingrediant(s) is in Loco Motion bath salt?

I purchased 4-Methicathinone pure crystal mephadrone online and it wasn't the same as loco motion is. The pure seemed like the main ingredient for kush blitz, tranquility purple, charlie horse, and etc. Plain label loco motion seems to be a stronger plant food or bath salt than the pure 4-methicathinone was. Is the plain label loco motion the same thing just processed differently or would it be methylone rather than mephadrone?
