Product works well when you workout often. Customer service representative named Diego was so helpful and awesome for assisting me with my account. He replied to my queries right away and with excellent customer service! Thanks!

Worst Web site and Customer Service!
Customer Service is the Worst!! No matter what I click it try's to sign me up for another order!
Can not make changes as the web site takes me right back to ordering more product.
All I wanted to do was suspend my subscription but, now I want to cancel it as there is no support for customers.

Gainful was recommended to me by a… friend, Tennyson Tappan, personal trainer.
Gainful was recommended to me by a friend of mine who is a personal trainer, so I really trusted his judgement. To my surprise, Gainful offers so many options around dietary needs, which was perfect for my long list of cannot-haves, including dairy, gluten and soy. My powder has 3 ingredients in it. I compared this with JuicePlus+ and others at Whole Foods, and they have looooaaaads of ingredients and half the protein. I was really impressed with Gainful's formula- so few ingredients, so much protein. I typically have mine in the morning, mixed with 1 banana, some cinnamon, honey, and almond milk. Not a huge fan of stevia, so I avoid the flavor packets and find something naturally tasty for flavor. It's delish AND I have so much energy throughout the day. It's remarkable. Highly recommend this product for folks who prefer eating healthy, need energy to workout, and are mindful of what they put in their bodies.

gainz + losses
Protein has historically made me gain weight. Not kidding, like infuriating amounts of weight. I’ve tried corepowers, muscle milks, egg white, whey... I couldn’t lose a pound if I was drinking protein. I’d put on more muscle (which doesn’t happen easily for me) but the fat would go nowhere, and I’d gain a ton. Also? Not pleasant to drink. Tried gainful to see if it could help me. I’m finding it easier and faster to put on muscle and actually starting to see some real tone improvements. Mixes great with almond milk and some collagen and glutamine. Love the flavor change-up with the flavor sticks, makes it easy to get excited about drinking protein.

Body reclamation/revitalization !!
At age 62 my body was declining in overall strength so I vowed to get in long overdue shape through multiple avenues of exercise. While doing so, I was convinced by my 'Gainful' using daughter to begin using the product so that the exercise I was doing could build muscle and help me lose the fat... So now at age 63, I am happy to say I know its working... Thanks Gainful!
