I can't figure out if the line contain proteins or not. The site, when using filters, says it is "Protein-free" when locating products. However, MANY here and elsewhere say it is NOT because it contains hops and peptides.

Whom do I believe?

As someone who is reading labels constantly, downloading info and going through pages of biology books I've saved from undergrad and grad, I have have to say that it's extremely frustrating to find products that fit ones' need.

Even more so when a site says one thing, but then links you to a selling site that says something different.
