Huge bag great price.
Excellent flavor, chocolate brownie whatever. Delicious. Filling and It's too early to see results but I'll definitely re rate later if I blow up considering my metabolism. Great price for the weight and ingredients.

Great product
If you looking to gain, this is what you need. I don’t recommend taking this full blast to start off. Gradually work yourself up to see how your body adjust. If you don’t exercise 4-5 days a week this ain’t for you unless you looking to gain weight and not muscle mass.

Great for gaining weight
I love working out. I am naturally skinny, but have bulked up after years of training and eating right. This is the only protein powder that helped me see any real noteworthy results. You won't go crazy gaining weight but for me at least, it helped give me a nice push into breaking what I thought was a peak for natural weight gain (around 15 pounds more, after a year). Great for muscle building, but for those that may need to gain weight in general this could be used as well. They taste great. Least favorite is the Brownie one as it is WAAAAYYY too sweet. It feels like ur drinking brownie batter. The other flavors taste amazing when blended with milk, water, coffee, and fruits (whichever you prefer most). The drinks are also pretty filling. If you are on the beginning of your training journey, take it easy and eat light meals with it. Otherwise you may feel sick for a tiny bit.

So tasty and well worth the money!
This stuff tastes amazing. I bought the brownie batter flavor and that is exactly what it tastes like. Of course, it still has a little of the protein powder chalky taste, but only as an after taste, not while you are in the middle of taking a drink. Compared to other protein powders I’ve had, this one has had the least amount of chalky taste. The smell is just as amazing as the taste. It’s thick, but not too thick, just the right consistency. The only negative that I’d have to say is that it takes A LOT of shaking for it to properly mix. Maybe using a blender would work better, but I haven’t tried that yet. I just have a shaker bottle. It is a giant bag, I still have about half a bag and it’s been almost 3 months of doing at least 5 shakes a week. I think I got a great deal for what I paid. I wish it helped with weight gain faster, but I guess nothing is a magic pill.

Bad Batch...
I've been ordering the Fudge Brownie flavor for nearly a year and it always taste great, but this time it had a weird chemical taste to it. Soon as I begin to mix it i noticed the color seemed off. $82 bucks just to get a bad batch sucks. They are sending a replacement hopefully this one taste okay, if not I will no longer buy from here.
