Hi Andrew, Thanks for sharing your experience 😄
Most flavorful protein powder I've tried. It was easy on the stomach, and the scoop size isn't that large. It doesn't try to be a meal replacement, so it is generally fairly healthy. So far, I am enjoying this protein powder.

Hi Leelakrishna, Thank you for sharing your experience 😄
I have tried many different protein powders and they would give me the jitters, tasted powdery, made my stomach upset. I love gainful due to being able to customize it to my needs. The flavor packets are bonus because I get tired of having same thing over and over. So far I love it and I am on my second order

Hi Jasmine, So glad you're enjoying your personalized protein blend! Thanks for the review 🌟
I was struggling with weight loss for over a year. When I changed my diet, it was hit or miss with foods. Eventually I started shifting to supplements as a way to boost my performance. However, after going through multiple companies, I didn't know if I was doing more good than not or if the ingredients would work with my body. Gainful has made this possible without the mental stress. The pre workout and hydration packets are fantastic for post workout or as a booster throughout the day when I'm neglecting myself. And the protein powder with flavor packs are a definite feel good. The only thing I do now is use small supplements for other needs which has given me a lot of room in my bag. But above it all the RDNs are the unsung heroes. Answering my questions and putting me on the right track helps more than any diet method can!

Hi Tony, We're so happy to hear that Gainful is working out for you and that your Dietitian was able to help out! Thank you for sharing your experience 😄
I have to admit, I was pretty darn skeptical. I've tried plenty of protein drink mix products over the years and this kind of blew me away a little. It doesn't have a powdery mouth feel, it's not punch you in the face sweet or bland, it's well balanced. I was hopeful because the subscription is a little more expensive than I've paid in the past for the large containers of protein powder mixes, and I guess that old adage of "you get what you pay for" holds true here. I will say that the flavor booster I had today doesn't taste like peanut butter or chocolate, but rather vanilla. However, as far as vanilla goes, it's good! I'll be trying the mocha next time, looking forward to it.

Hi Sarah, Thanks for sharing your experience 🌟
Great! Just wish it was more customizable. I.e. bigger serving sizes/bags. Skipping months easily. Notification before it ships that it’s getting ready.
