In my opinion, now that the video has been removed and by the person who posted it - "removed by user" it now says, it was a sad attempt by someone to undermine Antares.
No company, NO COMPANY, can market a product (or in this particular case) to put out a video on a product unless the product is approved by the FDA. The FDA cracks down on attempts like this and punishes a company that does attempt these sort of things. This attempt would only serve some sinister person who is shorting the stock or a sinister motive by Antares competition. And I don't think the competition would or could be so incredibly stupid to try such a thing and have it back fire and face SEC and FDA sanctions.
On the bright side, someone is really desperate, plus someone is really dumb.
