The best protein I’ve used!
This protein is so delicious! None of the flavors are artificial tasting with just the right intensity of flavor! It has helped me in my workout and diet routine. I look forward to using it for a long time!

I love this protein. I veered away from Whey for a long while because it made me feel awful. After learning more about the different whey types and finding out that some have less lactose than others I decided to pay a little more and try out Gainful. I use it almost everyday. It taste good, helps keep me full a long time and I do not feel like my gut is at war with itself. If you are like me, check this out. It’s good stuff.

I love Gainful! Everything from The ability to customize your blend, pick your monthly flavors, change shipping, and get personal attention from one of the registered dieticians. The customer service is always prompt at replying, and they are always wanting feedback to improve their company. Finding a company that truly cares about their customers is rare these days. Quality product, pricing, and transparency. You won't be disappointed.

Not only is the product great, but their customer service is really excellent. They’ve helped me multiple times and are just the best. It’s so common to reach out to customer service and not be understood— not here. To me, that’s reason enough alone to stick with them.

I placed my first order at Gainful and quickly realized my protein would be sent to the wrong place. I sent an email asking for them to change the address. Diego reached out within hours and corrected the problem. He even took the time to follow up after fixing the problem. Not only does Gainful have great customer service but their product is the best. Specially formulated protein just for me and it’s delicious. Regardless of what your fitness goals are, give Gainful a try.
