Bests & Worsts Reviews from Amazon

Having discovered Vital Proteins Collagen peptides, I was thrilled with the results. When I found Sports Research's product I was excited to find a comparable product at a much more affordable price. I was sadly very disappointed. Sports Research's product has messed with my digestive system in a horrible way. I've had horrible gas, diarrhea, constant stomach aches. I continued using the product because I experienced gas with the vital proteins, but it went away after a few days of my system accepting the peptides. Not with this. I gave up after 2 weeks. I'll be going back to the Vital Proteins product.
