Highly reccomend
This protein weight gainer has been a game changer for me. It mixes easily with water or milk and has a smooth texture—no clumps or gritty aftertaste. The flavor is actually really good, which makes it easy to stay consistent. I’ve been using it daily after workouts, and I’ve noticed steady weight and muscle gains without feeling bloated or heavy. It’s filling, keeps me energized, and fits perfectly into my routine. I also appreciate the solid protein and calorie content—it does exactly what it’s supposed to do. For the price and quality, this is an excellent weight gainer. Great taste, effective, and easy to use. I’ll definitely be repurchasing! 💪

It’s a good product and it works
If you’re a petite girl and really want to gain weight and see it come on within lease a month or two this is one of the best protein powder is milk replacement out there I believe in my opinion the flavor is really good. The strawberry and banana flavor. I feel like it’s really good and can’t be mixed with other things as well. I haven’t had another flavor. I’ve been saying true to the strawberry and banana, but if it’s not broken, I don’t fix it so it works perfect for me as well as me feeling pretty full with drinking it but not too full to wear I can’t have a breakfast on the side or maybe a lunch on the side but as time goes on your appetite will build so it will allow you to probably be able to eat, and drink around same time, if that’s what you’re aiming for. It’s super easy to use either milk or water. It totally depends on you.. it dissolves pretty good but I do suggest that you blend it for a nice period of time

Great! Worked for me
I've noticed a couple pounds of muscle packed on. I have a high metabolism and very active lifestyle so packing in calories and protein can become a challenge. This product flavor is pretty good! Not chalky like most protein. Great bang for the buck. Hasn't upset my stomach like most people complained about. Definitely getting another one once this is finished

Helps me keep my weight up while on a 14 day on off schedule
Great for keeping my weight up while at work for a 14 day hitch. It does make me bloated with milk or water.

Best tasting mass builder out there. This one works too so if you’re someone who struggles to put on weight give this a go

Bought this to put on weight because I have a high metabolism and it does make you feel full. It also helps to incinerate body fat while building muscle mass. I find it works way better than isolate and for its price I can't say anything is bad about it if you mix it right.
