I love the ability to customize the size of the flavor boosts. I love the ability to customize the flavors. I get sick of having to stick to a whole canister of one flavor so the flavors boosts are genius. The unflavored powder also allows me to sneak protein into a lot of other foods. I tend to use 2 flavor boosts per shake but I also use about 1.5-2 scoops of protein. Maybe creating an XL flavor boost with double the powder could be an idea for those of us that go big with our shakes! Or little cannisters with their own scoop.

Love the products and people working there! I've never found other protein powder mixes particularly tasty, but everything I've tried at Gainful has been delicious and smooth. I enjoy the subtle flavor of the mixes alone as they are (usually with soy or coconut milk), but sometimes like to play with a flavor boost. I also have a sensitive gut and I'm very pleased this does not upset it. The folks at Gainful are also super friendly and helpful! Very, very happy with my experience.

Best proteins on the market! I hated all the protein powders I’ve tried until i found Gainful! First, the fact that the proteins are customized to fit your personal goals is amazing. Secondly, the taste is by far the best I’ve ever tried and I’m really picky. It’s awesome that you can add flavor boosters on the side and that the protein itself is unflavored so you can put it in anything you prepare. The flavor boosters taste really good compared to other flavored proteins on the market that are usually undrinkable in my opinion. Finally, the access to a nutritionist and the possibility to retake the quiz whenever you want is truly great. These proteins are just the best option in my opinion. Maybe a bit expensive, but 100% worth it. I’ll might consider trying other products like preworkouts in the future. Thank you Gainful!!:)

Great products, better service The products speak for themselves. I look for high quality ingredients in my supplements and gainful does a great job. No sucralose in the pre-workout and all organic ingredients in the protein. The shipping intervals are acceptable and im pleased when i receive my subscribed order. I do wish there was an expedited shipping option which i would gladly pay for, and the customer service is prompt.

Love it and the team Gainful is the first and only supplement I've ever tried because I started working out 5 days a week. I enjoy the protein powder after a workout! The team is also super great. Always responding fast and positively to any questions or concerns I may have. They also do live events where they talk about Gainful products which has been helpful. Thanks!
