Love your product and your idea about customized protein and preworkout for what you’re trying to do with your body. I’d love to be an ambassador

Hi Greg, Thanks for sharing your experience!
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!!:)
