I love this product🥛
I love this product. Minimal ingredients, great flavor and I love that I can flavor the protein powder base with one of the flavor packets of with healthy ingredients I have at home. I add frozen cauliflower to make it creamy without the sugar and frozen fresh spinach for added nutrients.

Amazing products
Amazing products! The pre workout is super clean and doesn’t leave any weird after tastes. The hydration sticks are a great addition to the lunch and afternoon time to keep the energy up. And the protein shakes taste great! Gainful is and will continue to be a key resource to my overall health and fitness.

My feedback is based upon actually…
My feedback is based upon actually received the product and using it. My experience is my own but based upon decades of using supplements. My experience is limited to the protein powder they formulated for me. First the FLAVOR is watered down. I used the exact amount of water indicated for mixing and it results in a watered down flavor result. The taste also has a slight burnt aftertaste (best I can describe it). I will state the protein powder mixes easily and completely with no residue (in a simple shaker bottle). Finally I question the actual inclusion of all the ingredients stated. My formulation was supposed to have carbs, creatine, and other supps on it yet the scoop is smaller than other products I have used that were only protein powder. When additional ingredients are added, it stands to be reasoned that the scoop must become larger. My conclusion is gainful makes a weak flavored supp that fails to contain stated ingredients for a premium (high) price tag. There are better options out there who are honest about ingredients and you don't have to compromise flavor or taste.

My personalized formulated whey is simply amazing. Im starting to see great results in just a very short amount of time. I love taking my supplements after a long session of working out, and the feeling is just amazing. I'm once again on a healthy path and I just feel great. Another crazy thing is that I don't crave sweets not nearly as much as I did before receiving my supplements. This brand is amazing.
Ps.... if I can get a free bag of my personalized whey, that would be nice.

Amazing customer service
Loved the tailored protein and creatine. For personal reasons, I had to take a break. I contacted gainful and asked them to stop my next order. This was after it appeared to have already been processed and shipped. I received an email response within 5 minutes saying they were taking care of it and refunding me right away. I will be back in the future. Customer services is everything. THey are great!!

I love the ability to customize the size of the flavor boosts.
I love the ability to customize the flavors. I get sick of having to stick to a whole canister of one flavor so the flavors boosts are genius. The unflavored powder also allows me to sneak protein into a lot of other foods.
I tend to use 2 flavor boosts per shake but I also use about 1.5-2 scoops of protein. Maybe creating an XL flavor boost with double the powder could be an idea for those of us that go big with our shakes! Or little cannisters with their own scoop.

The customer service…
The customer service was very understanding that my original protein choice for my first order was not a good match. After being able to change my choice with a replacement protein, it was definitely a better match for my fitness/health needs. Thank you!

All marketing, poor product!
Pretty sure most of the reviews on here are paid for because Gainful is definitely NOT worth the money! All marketing, poor product. You feel as if your product is being personalized because they print your name on the bag when in reality they have a few different blends that they’ll match you with based on your survey.
Protein powder:
I paid $70 for a month worth of protein and it’s definitely not worth the price. Absolutely no flavor in their blends. In order to Get any sort of flavor you need to add 2-3 of their flavor packets…which cost extra ;). When you complain about the flavor, they just tell you to buy more flavor packets (dollar signs in their eyes).
Result wise, I feel like Gold Standard or any of the other mainstream protein powders are much better…cheaper, and ACTUALLY have flavor.
Don’t fall prey to the hundreds of positive reviews on there as I did, go elsewhere for cheaper, quality product.
