New customer for life

Andrew April 9, 2026

I've had a problem with gaining weight my whole life (39yo) man and recently I had tried this product and went from 98lbs to 120lbs in 2 months I don't follow the recommended dose and only use 1/2 a scoop daily once sometimes 2 times a day but omg I had to order the bigger container as I have found this product to be very helpful. I do not experience any bloating or discomfort of any sort as I have with others I've tried. I am a home health aide and exercise regularly so I am also seeing definition in my muscles that I am now putting on. I am sharing this product with family and friends struggling with weight gain and watching as they too experience the positive impact this product has on the physical body.

GREAT PRODUCT HIGHLY RECOMMEND!!!

Hannah September 9, 2020

I ordered this two days prior to my weight gain journey and it came literally 8 oclock in the morning on sunday. It was sitting at the door step TWO DAYS after i ordered it. Omg if wouldve ordered it off of amazon, id probably still be waiting for it. Anyways, ive been using this for the past two weeks and its been working great for me :) i use 2 full scoops, 3 cups of milk, 2 bananas and a tad bit of chocolate syrup before my workout

Pretty good!

Nate December 29, 2023

I’m excited to see the results of using this product! It does taste good when BLENDED with something else. I used half a cup since this was so expensive and put in some of my chocolate nutrition powder with it along with some banana to compliment the taste.

Good

G August 29, 2024

On my 7th or 8th bottle probably, this is the real deal if you’re trying to put on weight. The milk chocolate is my go to, but all the ones I’ve tried were actually pretty good taste wise. it’s one of the few powders that Id say taste like what it says it is, like my favorite is milk chocolate, and it actually taste like a chocolate shake when I make it.

Best one on the market by far

Sarah March 3, 2026

Closest to chocolate milkshake you’ll get. Suggestion. Let it sit in the fridge after you mix it, let it sit about 10 minutes for it to settle cause it’s bubbly otherwise, plus it helps settle any clumps that might still be there. (I’ve used a shaker, ninja blender and a portable blender they all still leave small clumps so trust me on this) if you’re looking for extra calories for weight gain specifically, I suggest adding 2 scoops of vanilla bean ice cream plus a bottle of water and then the 2 scoops of the mass gainer. In 3 days I noticed getting plumper. I I think I have a low key eating disorder so take my advise when I tell you this stuff works to gain weight. When you can’t eat when you are stressed when you just can’t do anything, at least drink this cause it goes down easy, it’s not too thick, it’s perfect and again if you add the ice cream it’s like you’re drinking a thin chocolate shake. I had to buy the big bag cause this stuff works so well. I haven’t tried with yogurt but ice cream faaashow. Don’t waste time with the other crap other companies sell cause they don’t taste this good. I got one more expensive and it was chocolate flavored and tasted like trash and made me sick. I hate everything but somehow I loved this. So go with it. From one picky grossly skinny person to the next. Said with love cause we all gotta laugh about ourselves.

Huge help with weight gain

Fernando April 25, 2026

I got this product for my sister, she has trouble with gaining weight so she tried this product and she fell in love with it, she loves the chocolate flavor, and best of all she feels a lot better and healthier.

Sustained Energy Levels ​Unlike the "spike and crash" cycle of high-sugar foods, a balanced intake of complex carbohydrates, healthy fats, and proteins provides steady glucose levels. This means I managed to avoid the dreaded 3:00 PM slump and maintain mental clarity throughout the day.

Unsatisfied purchase

NiyokwizeraEuphrasie October 7, 2024

When I first opened the protein powder it was halfway gone. It was not filled to the top like previous ones I had bought. I would like my refund back and I will ship the protein back if needed. I will not pay for something that is halfway gone!

would be a 5 star...

anonymous July 20, 2026

so this has been a solid product for me for over a year... i started purchasing online because the 3ib in store go so quickly and got raised an extra $5... now online it goes from 89.99 to 114.99 and that was july 4th. an extra 25 dollars seems pretty drastic, ill be doing my research and looking for similar products from different sellers. 1 star for price jump
