Hi Isaac! So happy to hear that you're enjoying your protein blend and that you're reaching your goals! Thank you so much for the review!
Was looking for a protein powder to help with weight loss, my daughter recommended Gainful since she had been using it so I decided to try it and was really amazed at how good the taste was as well as how long it kept me full, and I am seeing results, will definitely keep using.

Very tasty, I love that is customized for my needs, the only thing I would like is a bigger pack, since I need to consume at least 3 servings a day.

Gainful has been more than helpful with mishaps in mix up with names and have been able to accommodate different shipping address due to military orders, very please with the product and ease of getting problems solved.
