Great Taste and Ingredients
Tastes good, good ingredients, price is amazing. Good amount of calories per serving which is exactly what I need when the GLP-1s make me not hungry.

It Works
Getting these extra calories, protein & carbs is really helping. I don't eat breakfast at all & hardly any lunch so I'll drink 1 scoop mixed with 2% milk in place of those meals (2 scoops/1 serving per day). I'm on my 6th container having 1 serving per day & went from 179-181 lbs to 188-191 lbs (6'00") in less than a month and a half. The chocolate peanut butter is by far the best flavor, especially if you add a Tbsp of peanut butter to it. It's also definitely helping with building muscle combined with lifting. Surprisingly fast results, great taste, a little high on the sugar, but great product.

flavor decent
One thing i love about this protein powder is that its filled with calories, carbs, and protein. when bulking using this is a must now the flavors could be better, No 1 the vanilla taste to me like cheesecake now cheesecake is good but im not a huge fan of cream cheese, so i got peanut butter chocolate and its drinkable for the calories i can deal with it but there arent a crazy amount of flavor choices imo

Great taste
Great tasting product, and mixes well. This product has played a key role in the weight gain for our 15 yo son.

Good product
Great product. Does not make me feel bloated or sick. I got probiotics just in case but ended up not needing them. This is NOT a meal substitute. It’s best to use a blender, especially if you follow the serving size and suggested amounts of scoops. It’s thick and at first will feel like sludge. This particular flavor doesn’t really have a strong peanut butter flavor so I would add addition peanut butter. The taste is pretty good though. TIP: I drank this while eating a simple carb fruit like an apple or a pear
