In any other domain, I and most others would refuse to do business with anyone who insults our intelligence, treats us like crap, and rips us off. So I believe that as a matter of principle, if a supplement company produces just one product that is a scam, or lies in any of its advertising, we ought to protest that by boycotting all their products.
Meatheads of the world unite, and teach the evil supplement companies that we won't be jerked around and ripped off any more!
