I can't believe that this practice could be justified. It is intentionally deceptive and on that count alone it is unethical. Listing the ingredients and their amounts followed by "No BS" misleads you into thinking they're giving you the whole story, when they're not.

Also, what if someone did assume that those were the only ingredients and didn't bother to look at the back label only to find out too late that they were allergic to one of them? In this kind of case you can't just blame the consumer for assuming what the company obviously wanted them to assume....
