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.

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 stuff! Love that there is a Registered Dietician you can easily reach out to with any questions. The personalized protein is fantastic, and I enjoy being able to swap between flavors. I also don't have to worry about having a huge tub I have to go through before trying a new flavor, and I can opt to skip a month if I haven't been as diligent in my workouts for a while.

Sham Decent tasting, fine product. Absolutely not actually personalized. The "quiz" gathers extremely base information about you and your diet, along with a couple questions about your goals. But in the end, you get one of just a few pre-made blends of supplements. There's no semblance of biometric personalization or any other science to it. It really is "what protein can you ingest? Plant or animal?" Honestly, if you already know the answer to this, you don't need this service in the least. Zero percent worth the cost. Save yourself time and money and just go buy protein mix from your local grocery store.

Their shipping time is horrendous Their shipping time is horrendous. They claim 4-7 business days. I will be at 9 business days since ordering (12 days total). I have requested a refund or discount and they offer absolutely nothing. I’ll have to buy another protein in the meantime just because they send their items via snail mail.
