Great product and customer service to match. Gainful has it all!!

I for one have bought multiple protein powders In the past from MP, to MMX, to muscle milk, and walmarts body fortress. Gainful blends nicely I can add my creatine to it for a nice after workout drink. I love the flavor sticks, not being stuck with a tub of one flavor is nice. I like drinking my gainful with protein almond and cashew milk.

Have had no problems just a great protein
By Douglas A.
I really enjoy using Gainful protein. I like that is customized to my workouts and the flavors are fantastic. I enjoy having a variety of flavors during the month - as opposed to other proteins which require you to choose chocolate or whatever for an entire month.

I love this brand, my only concern are the flavor sticks. I've been subscribed for about 6 months now and have enjoyed my whey protein isolate mix. I normally do two scoops a day with 8oz. of Soy Milk and it helps me reach my daily protein goals without having to eat a lot or worry too much about where I'll get my protein from. My only critique is that they have not offered the Strawberry Milkshake flavor sticks in months. These are my absolute favorite and all I would get if possible. However, Cookies & Cream are a good second choice that seem to always be available.
