Query: why buy a pill when you don't know what's in it?

I got here from a website I'd never seen before, which purported to "review" alternative medications. But the link to "BUY NOW" was in the middle of the "editorial review" - which happened to make this pill seem like a dream. This was my first suspicion (I've been a journalist for many years, and no self-respecting journalist would allow this merging of content with advertising).Then I arrive here and see that the ingredients are "proprietary," which means I cannot research them or - in fact - ever know anything about them. I went to the company website and asked - by email - for specific info on the ingredients of this supplement and have never received an answer.So, that would be my second suspicion of this supplement and this company.Best advice: Don't put something in your mouth for which you are not told the ingredients. EVER, EVER, EVER
