Yeah, they're trying to scare you into buying their product. And the funny thing is, there is no such thing as a pill or chemical of any kind that has been shown to increase penis size. I just did a litle research and it seems the only possible methods for doing so are surgery (which generally have negative side effects far outweighing any gain) or continuous traction over very long periods of time.

To be honest, my member is on the smaller end of the averange range, but I don't let it bother me. I accept my body for what it is and anyone who can't accept me for who I am can fuck off. If a chick stops loving me because of my penis size, I don't want to be involved with her shallow ass anyways.
