I use this as a meal replacement so not the full dose. I use 1 scoop not 4. The taste is good for whey product, better with banana and berries. The overall cost is low compared to many others.

Meal Replacement

Great Deal

Great taste

I'm not a body builder, but I use this as a meal replacement when there's no time to eat. The other stuff that isn't marketed towards bodybuilders has absurd amounts of sugar

This tastes good if you mix it in advance, giving it some time to settle. It's not so pleasant if you mix it and drink it immediately.

Works with a shaker cup- no blender needed.

Meal replacement

My brother and I, buy and eat this all the time. He's gained 50 pounds of muscle and I've gained 20.

Awesome

This is a good Mass gainer if you want to gain weight, I've already gained 5 pounds and I've only used it for a week. It tastes good too

gained weight already

Fairly good for the most part.  One thing that I didn't see buying this... it does contain whey protein.  I've found I feel fairly bloated when having this.  There is a slight after taste but overall not bad.  i'm glad the packaging isn't one of those hard plastic containers.  It also arrived fairly promptly and right to my door (i've had issues with Walmart online before).  i'll likely get this again.

Overall... positive - but it does contain whey

PRO's. tastes good, dissolves into water well,  bag seals great because of the velcro the bag is big.

CON's  you absolutely BLAST through it. the 5lb bag might last a week used as directed. 
the scoop provided is MASSIVE and you need 4 scoops per serving. to hit the highest numbers on the packaging you need to use Milk of course. 

it's a good product but know going in you are going to rip though it and will need to purchase a lot more.  so it's maybe not the deal they proclaime it to be.

Good but not the best deal

[Employee of walmartcanada] Hard to dissolves in water and milk. According to me Chocolate flavor is just a name there's a little bit flavor of chocolate

Not bad but not very good

Didn't taste rite.
