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!!:)

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.

Not your AVERAGE protein powder I haven’t even RECIEVED my protein powder yet but I’m throughly impressed by the attention given to their customers. It’s a whole different experience than just buying any brand protein powder GAINFUL reached out to me to let me know they have dietician’s to assist me with questions over diet or exercise going forward this is on top of custom preparing your own protein powder. I really can’t wait to get my protein. Thank you again Gainful

2 stars because at the end of the day… 2 stars because at the end of the day it’s tasty protein powder, it’s the company I have issue with. I subscribed to this program without doing the math per serving. It’s about double the cost to a comparable powder like the Transparent Labs Whey. The email campaign is brutal, I don’t need 13 email in 9 days, I just want to take my protein and be left alone. It just ended up being too irritating to continue using so I moved on.
