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!!:)

Hi Sabz, Thanks so much for you review and for the feedback! We're happy to hear you're enjoying your Gainful 😁️
Really love the product. Highest in protein while staying low in carbs and fat which is great. The flavor boosts are a nice way to try different flavors without having to commit to a full size of one flavor. I'll likely continue to use Gainful. The only thing I'm not a big fan of is the pricing - it's a little steep for the amount of product you receive. Otherwise, Gainful is definitely helpful as part of my nutrition plan.

Hi Trevor! Thanks for leaving a review and for the feedback!
I have been trying to cancel my recurring orders for two months and today they once again charged me for products I do not want/need. My login attempts keep coming back as not registered. I have tried texting and get no reply. I replied to their email and it came back as non-deliverable. I will not pay for another shipment and need this to account to be close and have no way to reach this company!
