No need to be sheepish, but you are correct. "Enzyte", "Longinexx" (love that name) and the like are complete scams and the amazing thing is that people actually pay for them. But don't take my word for it, let's check in with the Mayo Clinic. And think of it this way, if they did work, then all of us would have large penises. That WOULD be interesting because we would then actually learn if size matters, but we are as God made us.
