That's what I would say. I buy Martins Premetherin at my local feed store (Raceland Ag) and it clearly reads on the label..... "For Use By Licensened Pest Control Proffesionals Only" so I'm guessing that must be the pro formula. What I'm trying to say is you can buy commerciall grade chemicals at your local feed store. When I had my dog I would even buy his vaccinations there it was less than $20.
