The base product is good. I just wish the flavor was already in it. The flavor packs are inconvenient for traveling

By Eddy
Very good product, better nutrition than any other I've used.
By Jordan
Love my Gainful! I started working out in the mornings before work and found myself starving during my commute in. I was looking for something convenient without extra fillers. Really appreciate the transparency of its ingredients and why it’s in my blend. The fact that it actually tastes good is a huge bonus!
By Luna
Good well with just about everything.

I love the flavors they offer. Caffe mocha is my go to, but I like to switch it up every now and again so I get vanilla and strawberry flavor sticks as well. Plus it’s personalized to me

Ordering from Gainful is so easy and I love the subscription service! I had to tweak my delivery times a little bit, but after a couple of orders I figured out how often my protein powder needs to ship. I like the idea of changing up flavors every now and then. It’s adds a little more work prepping, but I don’t get tired of the flavors. I love the quality and taste of the Gainful powder. It’s mixes well with a blending bottle. Other powders are chalky and sometimes need an actual blender to dissolve.

I love this protein! I like that it is personalized to me and the flavor is good as well.
By Rashele
This is my only option. Every other protein powder out there has sugar.
