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.

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.

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.

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!!:)

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.
