WEB SITE FOR SAMPLES OF PROTEIN DRINKS
I don't know a free one, but I went to www.bariatriceating.com and ordered a sample pack. I found some sites later with lower prices for buying the full sizeds items, but that may be a good place to start. There are several websites that offer samples for about $2 each. I just typed protein samples or something like that into a search engine when I was looking for samples and I remember that some did come up that offered free samples in exchange for filling out info.
