Not only does the protein powder perfectly fit my nutritional needs, help me lose weight, and have plenty of flavor options, but the customer service is excellent and I feel like the company really cares about health. Highly recommend this product.

Gainful is very promising.
Now I will say, I don’t have many other products to compare Gainful to. In fact, Oats and Whey is really the only protein powder I tried. And it tore my stomach to pieces. Gainful, on the other hand, doesn’t do that. I’ve actually gotten comfortable enough to take a shake with me to work. I am a landscaper after all. So that means I don’t always have access to a bathroom. Anyways, in the few weeks I’ve been using Gainful, I truthfully have noticed results. I’ll take my shirt off after a nice, lengthy workout and flex. And I can spot out a more cut, refined, definite look to my physique. I’ve been lifting weights since I was 13. I turned 18 in March and this is the first year I stepped my game up and took a more consistent approach to working out. More so, adding variety to my workouts, like an athlete would. So, with that in mind I’m nothing crazy. But I’m getting there and I’m feeling confident in your guy’s products. I really like how customers are able to alter their own powder too. Specific to their goals. I took priority in healthy gains and muscular recovery. Pair this powder up with a nice stretch and foam roll session before you go to bed and you’ll wake up in the morning feeling like Superman. Once again, In terms of products I’ve tried, there are only a handful. I plan to venture in the future. But for now, I see no reason to. Because I’ve honestly, thus far, have only found greatness in Gainful.

Outstanding service and product
Gainful is my favorite protein brand and I will only be using them for all my fitness supplements! The customer service and dietician is always responsive and detailed to meet my concerns. I absolutely love that I can change the flavor every time I drink a shake because I never get bored with the blend!
