Chocolate Lava Cake!!! Not a fan of this at all! Simply gross! I went off reviews on this buy. Saying it taste just like the picture. The heck is does!! No! Very bitter and somewhat sweet! After taste is not good! Way better isolates out there! I should have known better with how cheap it was! Do yourselves a favor and buy a quality whey protein isolate! Not this one! Gave it a 2 overall rating only because high protein per serving and It’s cheaply priced! Taste rating is -1 which is not on’s scale so letting you know!

Container came damaged resulting on the protein powder spill all over the box it was shipped. Been approximately 2 months and still haven’t got any word back.

Easy on the stomach. Chocolate lava cake is a bit on the sweeter side and does need a fair shake compared to the vanilla ice cream. Vanilla ice cream has an after taste to it, but mixing it as a smooth is excellent. Bought it for the great nutrition value.

Chocolate lava cake is good in water, almond milk or mixed into a sludge and eaten. Definitely more of a dark chocolate taste, slightly bitter. The Vanilla is good in almond milk, but if mixed up to be eaten it has a distinct chemical taste.

I did a review a while back on the Cookie Butter flavor which I was NOT a fan of the flavor but now I just finished a 5lb tub of the Choc Lave Cake and YES this flavor taste exactly like the pic on the front of the container. The flavor is a rich dark decadent chocolate so IF your a dark choc fan they I think your gonna be a fan of this flavor like I am. I love dark choc and when it comes to a straight whey Cellucor Molten Choc is one of the best tasting choc flavored whey's in my opinion. This XTEND Choc Lava Cake ranks right up there with it.. The powder mixed very smoothly with just a bit of foam but no floaters and the flavor hits with a deep dark flavor with just a slight bit of bitterness but it wasn't a overly sweet bitterness just the kind you get on the back end of the flavor so that's why it didn't get a 10/10 on flavor but a 9/10 is a very good rating for an isolate because usually isolates are weak in flavor but there is NO weakness in this flavor and again you have to be a dark choc lover to appreciate this flavor. People who have reviewed this protein and claim that it's spiked need to READ a little better because the label specifically shows 25gm of protein per serving from pure protein. The added bcaa's is not factored into the 25gm that's why they list it separately and it's equal to 7 gm of amino acids and the co. stated why they added the 7gm cause they are a bcaa co. so they wanted to add the same amount that their famous formula of XTEND contains. Spiked proteins DON'T list the amount of bcaa's added they just factor it in Nutrabolt shows you exactly what the bcaa's they are adding to the protein. This isolate mixes a bit thicker and creamier than other isolates which I LOVE and that's because they use NO soy lecithin and sunflower lecithin is used instead and a few other thickening agents. I personally LOVE this Choc Lava Cake and I will purchase it again in the future and I might also try the vanilla. I would HIGHLY suggest if anyone is interested in this flavor try and get a sample first to make sure it is too your liking before purchasing a 5lb container.

The taste is almost there, but there is a slight mechanical/artificial aftertaste to it. Not what I was looking for, but not bad. No problems with the mixing.

Worst tasting protein I have bought. I wish there's a negative rating.

This is one excellent tasting and easily mixing protein. 25g of whey isolate with an additional 7g bcaas make this an excellent recovery product, and natural flavors ensure there's no artificial colors. Artificial sweetener is still used however, but it's taste is absolutely amazing. Complete mixability in just a few shakes and it all goes down smoothly with no bitter or weird aftertastes. Very low in the sugar and carb dept, leaving only needed ingredients making up the majority of the scoop. The price is pretty reasonable as well for an isolate protein. Pick one up and try it.
