I am naturally thin and require a gainer supplement to gain strength and mass quickly. I've tried many throughout the years and I prefer this gainer over any other I have tried. Does it have 1000+ calories? No. Do you need that many calories in your gainer supplement? Probably not. I don't. I get the rest of my calories from food. When I want to gain strength and size quickly, I drink one of these every night.

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!

This gainer is probably one of the better gainers on the market. Comprised of all REAL food and majority Stevia sweetened, tastes like a milkshake. Gives results, no bloating in my experience.

I Like the rich chocolate taste and it mixes easily with no clumping. Also, it has caused no digestive issues and I like the 30 grams of protein. I have put on approximately 5lbs and am almost at the goal I have set for myself. The only downside is the last container shipped had a square scoop with a spout instead of the original round scoop. Along with the short handle makes it almost impossible to remove the powder from the small opening in the container without spilling it all over the counter etc.
What garbage shipping time! Is this coming from China?? I ordered this November 10.. it's November 20 today and still hasn't arrived!! Last time ordering from this website! They took forever to even start the process. Absolutely pathetic!!!!!
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.
I looked at the reviews. It’s in the top five of the best weight gainers. And the taste is amazing: two scoops of protein , handful of spinach, frozen fruits, 1 dessertspoon of maple syrup, 2 tablespoons olive oil, sliced frozen fruits (of your choice) …a DASH of peanut butter. Blend that up, enjoy!
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 ... MoreOk first off I wanna say that I'm a 6'2 male and before I started taking this powder I was at about 165.

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.
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 ... MoreReview in one sentence: this isn't the worst protein/mass gainer I have tried, but it is far from the best.

This mass gainer is the real deal!! By far the best I've tried to date, and I've been through my fair share of proteins. I ordered the creamy vanilla flavour and it tasted just like a vanilla ice cream. Threw a serving into and shaker cup with water, gave it a few shakes, and it was perfectly mixed, and tasted unbelievable. And it's clear why they call it "Clean Gainer". The ingredients that this stuff is made from is unreal! Organic quinoa, blueberries, rolled oats, brown rice.. And the list goes on! It's basically like taking all the superfoods and blending it into one formula. The fact that this stuff is pretty cheap too, makes it that much better. RIVALUS is doing things right, and this will definitely will be my new mass gainer for when I'm looking to bulk up ... MoreThis mass gainer is the real deal!!
