I buy the chocolate lava cake and vanilla on a regular basis. Flavors taste great and natural.

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.

Pretty good protein isolate at a competitive price. I love the chocolate lava cake flavor. Cookie butter tastes like one of those butter cookies we all probably got at the store as a kid. It's that sort of butter cookie. I can't remember the exact kind or name brand, but one of those Nabisco or whatever kind. Vanilla tastes like legit vanilla. I'm not a vanilla lover, but I think this vanilla would please most of those that are. Also seems pretty similar to Kage Casein Vanilla in terms of flavor.

Good standard protein with the BCAA's that XTEND is known for. The main plus of the protein for me is the taste. A lot of other proteins I've tried from other big names have a strange aftertaste that almost makes me gag, but this protein doesn't have that. It's a good clean flavor and it also mixes a lot better than many other proteins I've had. 10/10 would recommend

For any caramel flavored protein powder I've ever tried this is honestly the best one yet. It has a unique flavor signature and it makes taking my post-workout protein shake way more enjoyable.

I’ve had many different proteins but I keep going back to this. Chocolate Lava Cake is amazing!! Vanilla Ice Cream is very good as well. It mixes really smooth and is at a good price. Highly recommend it!!

Incredible tasting protein, just a shame that it's spiked. Added BCAA's listed in the ingredients list is how companies spike the nitrogen content of their proteins - so they can claim '25 grams' but in reality you're only getting 15-16 grams per scoop; sometimes a little more, sometimes a little less. Disappointing.

First of all, this stuff is frickin delicious. I used to barely put any liquid in my protein shakes because they tasted so bad, and I didn't want to drink them for longer than necessary. This stuff is actually pretty enjoyable to drink. I have the chocolate lava cake flavor--it's a rich chocolate taste without feeling "heavy" like some powders, and is only made with natural flavors. It's actually pretty light and does not make you feel "weighed down," which has been my experience with some powders that are very creamy and heavy feeling. My only gripe is that it is VERY sweet. If that bothers you, you might wanna stay away. But it is smooth and easy to drink, and tastes good with milk or water. Confident it would also be great blended into a smoothie. It has 7G of BCAAs per serving, which is a plus. As for results--it has 25 mg of whey protein isolate per serving. I'm lactose intolerant and my understanding is that isolate has very, very low levels of lactose. Concentrate (which this is not) can sometimes have more. Regardless, this stuff does not upset my stomach. I'm no expert, and I can't tell you if this works "better" than other whey supplements--but it's packed with protein, tastes great, and is easy on my stomach. Will definitely be buying again.
