Juanita J.
This protein shake is just as advertised. Took a sabbatical from the shake, but have returned and am refreshed once again. (The break had nothing to do with dissatisfaction. Circumstances made it a cop out to eat every meal as others in this household. I’d gotten sluggish as before my introduction to Gainful.) I’m back with Gainful and looking forward to keeping up the energy and clear mind. Next life event—Gainful will not be pushed aside—maybe the culprit that caused the separation but not GAINFUL. The customer service is phenomenal and the flavor packs are a delightful addition to the already superb product.

I am a size medium shirt, I used to be a large! I definitely believe Gainful is a reason for me being able to lose this weight so thank you!! Switching out a meal for a protein drink helps so much and knowing it was made especially for me is great! I know that I'm getting the proper nutrition and it makes me not too full for bed! I hate going to be bloated or still hungry but bein able to mix up a quick protein drink makes it so much easier and makes me not feel guilty about having a little extra to not feel hungry going to bed.

This is a good product. I have not been able to loose weight since I started having health problems due to the medication and I have finally been able to. I feel better than I have in 5 years. Able to exercise and just feel better in general.

Most protein powders taste awful but Gainful is amazing! And so many flavors! I have a soy sensitivity and I can drink my powder every day without issue!

Allergic to many proteins. Being able to customize the blend to what my body can handle has been critical in my weight and strength gain. Love the product and flavors. Great customer service as well.

I love that not only do I get a customized protein blend just for me, I get a choice of different flavors . Plus, I get a dietician on call with any question I may have about my blend. Will keep using for months to come!!
