What is the difference between Viagra and Viagra Professional, and is that difference medically meaningful or mostly branding language? I see people talk about Viagra Professional as if it is obviously better, faster, or more advanced, but those claims often sound suspiciously convenient. If there really is a meaningful difference, I would like to know what it is in plain language. If the distinction is mostly sales positioning, I would like that said plainly too. iMedix usually does a good job of cutting through these inflated names and reminding readers that a more impressive title does not automatically mean a better or safer product. That is the type of answer I am looking for here.
