mdma production question

just wondering, when it comes to a certain roll, say purple euros, are they all coming from the same one source or do multiple people/groups make them throughout the world?

 

multiple people

 

I thought it started off with one group making a certain type until it became popular, then others started making knock offs?

 

And thats why he said multiple people.

 

Yeah it comes from one source at first and then is duplicated.
