This is the best tasting shake I have ever had. Hands down best, I am worried I will overeat this and get fat. It also mixes incredibly well, when you pour the water in it is half dissolved before you even shake it once. I wish this product was a multivitamin type like some other mass gainers, but its pros FAR outweigh that minor con.

Sucralose, Acesulfame Potassium... Never again until they remove those, this is not clean!

This is the best protein shake in the market. It’s not clumpy , it’s easier to blend with whole milk or almond milk. I’m loving the results, I definitely will order this again soon.

Best gainer I've used by far! No artificial sweetener taste, not too clumpy (I use whole milk) the scoops aren't huge and you don't need 4 scoops per shake. I do 2 scoops once or twice a day. I add creatine to mine and notice it mixes much better than without it. Weird. Recommend 100%

Bought this gainer for the good sources of macros it has. Throw it in a blender for a protein shake every day. Tastes decent with milk alone. Only downside to this weight gainer is that it contains unknown amounts acesulfame potassium and sucralose, chemicals that are 200x and 600x sweeter than sugar, respectively, as per the FDA. There are mixed professional opinions on these sweeteners (as there is with anything). Hard / impossible to find a gainer that checks every single box off your list though!

Great Gainer! Chocolate fudge has a rich flavor that is easy to mix and and a lighter texture than other gainers. It is low in fat and has essential vitamins, including iron, zinc, bcaa's, and a clean protein blend. Unlike others, I feel no bloating or other digestive issues and a good price for the amount purchased. I take Iso-100 prior to workouts and take two scoops of Rivalus gainer after workouts.

Good gainer for the price, almost dissolves in the water without even having to mix it. I don't feel awful after having a shake, just the normal Mass bloat. The S'Mores flavor just tastes like pure sugar though, doesn't taste like s'mores at all, though it does smell like them.

if you use this twice a day you will see results., but if you have bad diet you will quickly lose the weight that was gained. like all gainers it gives the ***** and the *****, but not as bad as some other. mix with water for meh taste mix with milk for bomber milkshake. the taste is by far the best out of all the gainers i tried and i tried quite a bit. chocolate fudge is by far the best flavor, but creamy vanilla is more versatile. you can blend some berries or peanut butter with it to change things up.

I love this product. Chocolate Fudge is the best by far. It completely dissolves in my shaker (rigorous shaking for 60+ seconds) and flavor profile is excellent. I've tried Cinnamon Toast and Cookies & Cream flavors and find them too sweet. Chocolate Peanut Butter and Cookie & Cream both had little undissolved particles that bothered me. Choco PB, I was hoping would taste closer to a PB cup but to no avail. I turned my sister on to this product for my nephews and they also love the Choco Fudge. That is the only flavor I buy now. Choco fudge. Yeah.

Great tasting. You need 4 massive scoops to get the calories they claim. 2 scoops barely fit in a regular shaker cup. If I use the same amount of powder with any other ordinary protein supplement, I end up with more calories than the Rivalus Gainer. Why not make 1 normal size scoop?

Ok first off I wanna say that I'm a 6'2 male and before I started taking this powder I was at about 165. My body is also the type that I seriously haven't gained 1lb in about 5 years. My metabolism is really high. I got to the gym almost every day and lift and I'm very muscular but always pretty skinny. Now I've taken this product before, I bought 4 5lb jugs and drank them and gained about 7lbs. The problem was, once I ran out and stopped taking them I went back to my regular diet and seriously lost every pound I gained. Decided to come back to this powder and really put in some work. I've bought 3, 12lb bags of the stuff I'm about done with the 3rd bag now and I haven't weighed myself for about 2 weeks now but last time I looked I gained 16lbs. Not at all saying that's all muscle but I don't care. Now it says 2 scoops is 1 serving at 520 calories i believe. I did 6 scoops a day every day to get where I got. If you don't do it every day or you only do 2 scoops a day, you will be wsting your money. The way i see it is if i can drink about 1800 calories and 90gs protein then that means i don't have to eat it. And drinking it is a lot easier. Only problem with doing that is no matter what flavor you get. They all taste disgusting and i have to force myself to drink them. Yeah its that bad. Now if you stop taking this once you hit your goal you need to start eating more. I don't really wanna do that so I'm gonna continue on this path and see where I go. My goal is 20lbs so ill he at 185. I hope this puts some stuff into perspective for some new people looking for a gainer.

Wow, best tasting weight gainer I’ve ever had, hands down!! It really does taste like a cinnamon cereal and there is no residual clumping like most weight gainers, it mixes perfectly and there is no chalkiness at all. Already bought 2 12lbs bags will probably get more.

Review in one sentence: this isn't the worst protein/mass gainer I have tried, but it is far from the best. First off, the flavour: I had high hopes for the chocolate peanut butter. When I received it, I opened the bag and it smelled nice, but when it came time for consumption, it was far from nice; it tasted expired or something. Whatever I was tasting, it was definitely NOT chocolate peanut butter... although, now, it's palatable (at best). It took about 20 servings before I got used to it. The only redeeming factors I have for this product is that it seems to be doing well in giving me clean(er) gains. It is also very mixable; I've mixed it with ice-cold water and it still blended completely. It's mostly clump-free (as it claimed on the bag) but there was still little grainy bits leftover.

I’m a contractor in Afghanistan where decent healthy food is hard to find. Hard a hard time adding muscle and weight. Starting taking the product in mid January weight was 180. Now in mid March I’ve added 15lbs of muscle and the taste is amazing. Just using water as a mixer. Without a doubt the best product I’ve ever used.
