Customer Reviews
Consistent quality, returning customer
This is my third time ordering from Gainful. I usually get the Personalized Protein Powder, but this time I added the Creatine Performance Boost. As always, the quality is consistent and the shipping is reliable; it took 5 days to reach Denver this time, which is typical. I keep coming back because their products always align with what I need based on my fitness goals, and I appreciate that. Never had any issues with the subscription either, it's easy to manage.
Fast shipping, good product
Ordered Personalized Hydration. Got the Tropical Punch. Arrived in 4 days. Tastes good. Works. No complaints.
Protein powder was great
I got the Personalized Protein Powder a few weeks back and it's been pretty good. I picked the Madagascar Vanilla Flavor Boost and it tastes nice with my morning smoothie. Shipping took about a week to get to me in Arizona, which is totally fine. Overall happy with it.
Good pre-workout, clear process
I ordered the Personalized Pre-Workout in Sour Blue Raspberry. The ordering process was smooth after I did the quiz. Delivery took 6 days to reach me in Seattle, and the package arrived in good condition. I appreciate that they provide a detailed breakdown of the ingredients based on my quiz results. The product itself mixes well and gives me a decent boost without feeling jittery. I've only used it a few times, but so far, it meets expectations. No need to contact support, everything was straightforward.
Decent value, could improve delivery speed
I tried the Personalized Protein Powder with the Cookies and Cream Flavor Boost. The flavor is actually pretty good and it mixes well. The personalization aspect is a nice touch, and I feel like I'm getting a product tailored to me, which is a good value for the price point. My main critique is that delivery took a bit longer than I expected, around 8 days to get to my place in California. Not a huge deal, but something to keep in mind if you're in a hurry. Otherwise, it's a solid product.
Love my new protein!
Oh my goodness, I just received my Personalized Protein Powder and it's amazing! I got the Rich Chocolate Flavor Boost and it tastes so good. It mixes really well too, no clumps at all. I was a bit worried since I chose the Plant Protein, but it's super smooth. I'm definitely going to keep this subscription going and tell all my workout buddies about it! Seriously, try it!

Share tips, ask questions & help fellow shoppers save more
Just took the quiz for the personalized protein, looks cool. How long does it actually take to get to you once you order? I live in like, rural Montana, so sometimes shipping is a pain.
Hey, thinking about trying Gainful protein. Does anyone know if they usually have any good sales around Black Friday or Cyber Monday? Don't wanna pay full price if I don't have to.
