Customer Reviews
Unreal protein, amazing results
I grabbed a variety pack of the 50g High-Protein Bars last week and wow, these are exactly what I needed! The chocolate flavor is fantastic and they really kept me full after my workouts. My muscles feel great after using these for just a few days. I'm definitely going to reorder. Everyone serious about gains should try these out!
Good for post-workout
I tried the peanut butter protein bars after seeing some buzz. They definitely pack a punch with the protein content, which is great for post-workout recovery. The taste was pretty good, not overly sweet. Shipping took about 6 days to get to my place, which was a bit longer than I hoped, but they arrived well-packaged. I appreciate the clear nutritional info. Overall, a solid product, but faster shipping would make it even better.
Solid value on variety pack
I was looking for some high protein options and GAINZ popped up. I snagged a variety pack of the 50g bars since it was a good way to try different flavors without committing to a whole box of one. The price was fair, especially for the amount of protein you get. I compared it to a few other brands, and GAINZ offered a good deal for the specs. Ended up saving a bit because of the bundle deal they had. Definitely felt like I got my money's worth and the bars are actually decent.
GAINZ Community Discussion
Share tips, ask questions & help fellow shoppers save more
What's the deal with returns if I don't like a flavor? Can I send them back?
Hey, wondering how long shipping usually takes for GAINZ bars? I'm in NYC and trying to time an order before a big training block.
Thinking of trying these out. Do they offer a first order discount or anything for new customers?
Are these bars available in any stores yet or just online?
does gainz offer free shipping? what's the minimum?
Thinking of pre-ordering some of the new flavors. Can you track pre-orders on their site?
How do these compare to Quest bars or MET-Rx? I usually grab those but 50g is tempting if it's worth the extra cash.
Can you stack coupon codes on GAINZ? Got a military discount but also want to use an influencer code if possible.
