In this article, I will be reviewing the Rivalus Clean Gainer. We’ll be talking about its features, and I will also be sharing my experience with using this mass gainer.

I’ve used this supplement to see how it will help my gains. So this Rivalus Clean Gainer review is going to give you the scoop on its pros and cons, and if it worked for me. I specifically evaluated the following features:

  • Macronutrient profile
  • Protein and carb sources
  • Protein quality
  • Flavors, taste, and texture
  • Pricing

So, if you’re intrigued by this “clean gainer”, read until the end of this Rivalus Clean Gainer review. That way, you can determine if this mass-gaining supplement is the right choice for you.

Product Overview

Before we get into the details, let’s have a quick overview of the Rivalus Clean Gainer.

It provides 560 calories per two-scoop serving. A five-pound bag gives you a total of 16 shakes to add to your diet.

From one serving comes 30 grams of fast and slow-digesting protein, 90 grams of low-GI carbs, and 7 grams of essential fats.

The best part?

All macros are from “clean” sources. 

This means all ingredients are natural and high-quality instead of cheap, low-quality fillers. So, this mass gainer is as pure as it gets.

Some folks prefer to do a dirty bulk, which means gaining fat along with gaining muscle. This is the fastest way to gain weight overall, but it can be unhealthy. 

So instead of getting the body of a Greek god, you’ll end up looking like Jabba the Hutt.

This is why I prefer doing clean bulks. 

It’s gaining as much muscle as you can while keeping fat gain to a minimum or none at all. 

And, it is the recipe to looking good naked every time… Although, you have to be patient about seeing the results.

You need to consume more calories than you burn to pack on mass. 

And, with all the empty calories from processed foods and deep-fried everything, finding those extra calories isn’t hard.

However, what’s hard to find are quality and clean sources of calories. This is where I found the Rivalus Clean Gainer. 

While I wanted to get some serious size on, I wanted to be healthy and maintain the low-body fat physique I worked so hard for — and I did.

If you are:

  • Bulking but want to look good and feel healthy
  • Mindful of your food choices
  • Someone who understands that a supplement is an aid, not a magic pill
  • Patient about your progress

Then keep on reading till the end.

However, if you:

  • Prefer dirty bulking to gain weight fast
  • Plan to replace food with supplements
  • Are a true hard-gainer with very high calorie needs

Then perhaps you can go for more extreme mass gainers such as Mutant Mass Weight Gainer or Dymatize Super Mass Gainer which have more than double the calories.

Here’s My Thoughts and Opinions on the Rivalus Clean Gainer

Nutrition Profile

The Rivalus Clean Gainer nutrition facts feature an 8-source carb matrix that delivers 90 grams of fast and slow-digesting carbohydrates and proteins. 

Given this blend, it is great for use any time of the day. I usually take it after my workout, but sometimes I use it as a quick breakfast. 

When to take Rivalus Clean Gainer is totally up to you.

The maltodextrin and fructose serve as a quick energy source while the low GI quinoa, blueberry, ginger, monk fruit, brown rice, and oats provide you a steady stream of energy until your next meal or shake.

Its 30-gram protein content is made up purely of milk protein with the two most popular and most effective proteins out there: whey and casein. 

The fats are all from healthy sources, namely MCTs, flaxseed, avocado, and sunflower.

Rivalus Clean Gainer’s ingredients are great.

It has no fillers nor empty calories. That is why it only provides you 560 calories per serving. 

And, I say “only” because most mass gainers out there give you 800 up to 2000 calories.

Is this a good thing? 

Well, if you want to maintain a lean physique or do not want to add any more fat to your body, then yes, it is.

This mass gainer is on the low-end of “high-calorie” bodybuilding supplements; and, for a good reason. It is easier to incorporate into a strict diet.


Rivalus Clean Gainer calories are just enough to help you go over your baseline calories by 300-500, which is really all you need according to studies.  
You’ll gain fat instead of muscle if you go over. Remember: the goal is muscles, not love handles!
Since it is a “clean” gainer, it aids you in increasing your daily caloric intake just a bit to keep you from gaining fat. That is the best way to bulk up. 

Protein Content

It contains a full-spectrum protein blend. Meaning, it has a combination of slow and fast-absorbing proteins. 

It includes whey concentrate and whey isolate to replenish your body and repair your muscles quickly. 

For slow and steady absorption, it contains milk protein isolate and micellar casein.

The proteins I mentioned are premium quality complete proteins. 

Hence, all of the 30 grams in one serving will go towards muscle protein synthesis, aka making gains.

Rivalus Clean Gainer also has BCAAs: l-leucine which slows muscle breakdown, l-isoleucine to promote muscle recovery, and l-valine for positive nitrogen balance (which is key to muscle growth).

One thing I would have liked is for the Rivalus Clean Gainer to have more protein per serving. 

30 grams is already good, but I’d like to have more protein in a day. 

Again, how you use Rivalus Clean Gainer is up to you. You can get more protein from other sources such as meat. 


Overall, the protein content is awesome. As long as you treat it as a supplement, which it is, the 30 grams per serving is no biggy. It is always great to have a full-spectrum protein source so you do not have to buy separate products like one tub for whey and another for casein.


This mass gainer is available in six awesome flavors. 

These include: Chocolate Fudge, Cinnamon Toast Cereal, Chocolate Peanut Butter, Creamy Vanilla, S’mores, Cookies and Cream.

You’ll never tire of the Rivalus Clean Gainer with this wide range!

I did not expect them to taste great considering there are only 8 grams of sugar per serving. 

Yes, I’ve already tried all flavors. I guess you can say I really like them, huh? 

If you were to ask me, the chocolate flavor is my favorite!

Another thing I enjoyed about the Rivalus Clean Gainer is that the powder is instantaneous. 

This means it is easy to mix and your drink will be free from clumps and chalky texture.


The flavor of this mass gainer is one of the reasons why I opted and still use this brand.
Besides the variety, I also like how consistently gourmet it tastes. 
If you are used to adding other ingredients to your shakes to make them taste better, you wouldn’t have to do that with the Rivalus Clean Gainer. 


The Rivalus Mass Gainer gives you 16 servings for every 5-pound tub. At 40 bucks a tub, that puts you at about $2.5 per serving.

It isn’t dirt cheap. 

But given the quality of the ingredients, it’s not that pricey either. 

Micellar casein, in particular, costs way more than most sources of complete protein. And, its carbohydrates are free from fillers, which is unusual for mass gainers.

So, all-in-all, the product does give you great value for your money. 

It’s made with high-quality premium ingredients that won’t put you over your budget nor too much over your baseline caloric needs.


This is a fairly priced mass-building supplement given how clean the macronutrient sources are and their quality.
 The lower overall calories make it easy to incorporate into your diet. And this mass gainer is not hard to incorporate into your budget either!

Check Out My Results From Using the Rivalus Clean Gainer

To make constant progress, you have to continually grow. 

And we take that literally in bodybuilding. 

But, what we want is to grow muscle, not fat.

Using the Rivalus Clean Gainer helped me in achieving exactly that. 

I didn’t have to do a “bulk season” to gain as much mass, muscle or fat, and a “cut season” to shed the fat gained. 

I was always on a clean bulk without having to follow complicated methods.

So, I always looked chiseled and ready for a photoshoot 😉

And by photoshoot, I mean me, my phone, and a good light source. No more hesitating on removing my shirt at the beach, in the gym, or in the bedroom.

With this clean gainer, I was jacked, diced, and shredded year-round.

Let’s take a look at some reviews, positive and negative, about the Rivalus Clean Gainer:

“This product is incredible if you are a hard gainer like me. I started supplementing with this about three months ago when I weighed 145 after only running for months training for a marathon. Lost all my muscle during that period. Started drinking 2 scoops upon waking, a scoop about 45 minutes before the gym, and a final scoop immediately after a hard workout. I have put 18 pounds on in three months. Starting body fat was 7.2%, now at 8.8%. Not bad for shoveling 3-4k calories/day! Couldn’t have done it without this product.”

“(…) I enjoy this company doesn’t promote BS products that provide filler products or halfway fill up their products. My favorite flavors are Chocolate Fudge and Vanilla, which both are blended perfectly and made perfectly without a bunch of bullcrap going into your protein shakes.

Rivalus deserves a 5 out 5-star review simply by not promoting “fake”; products and making protein powder exactly as it should be”

“Second time I’ve ordered this protein. The first product I received was amazing. Taste was great, easy to mix, loved it. I think the flavor was chocolate cake? This time around, it is disgusting. Seriously, not even like just cheap protein disgusting, but like, I think there is seriously something wrong with it. It tastes (and smells) like burnt plastic and chemicals. And my stomach instantly rejects it. The flavor this time is labeled chocolate fudge. What happened?!”

*Rivalus recently underwent a major rebranding and is now named Rival Nutrition

Is Rivalus Clean Gainer Right for you?

Now that we’ve covered the positives and negatives of Rivalus Clean Gainer along with sharing my experience with it, let us shift the focus on YOU.

The same with every supplement, Rivalus Clean Gainer may or may not work for you. So, I’d like to specify who this mass gainer would be best for.

For clean bulkers that aim to build lean mass:

If you care about how your physique looks, then doing a clean bulk is the way to go. 

And, the Rivalus Clean Gainer would be a great choice. 

The lower calories make it easier to incorporate into your diet. Therefore, it is less disruptive to your pure muscle-building journey.

Not to mention, just slightly going over your caloric maintenance is the healthy way of gaining weight. 

This supplement delivers you the macronutrients you need and just the right amount of calories to nudge you over that number.

Most mass gainers with their super high calories require you to adjust your meals to accommodate their calories. 

With Rivalus Clean Gainer, you don’t need to modify your meal prep at all. You simply add a serving of this supplement in.

For patient fitness buffs that build their physique, not their ego:

Sure, having the scale jump 10 pounds higher in a matter of weeks is nice if your aim is to gain mass. 

But, did the increase come from muscle or fat?

Patience is a virtue, and this rings true in trying to gain lean mass. 

Adding muscle takes more time compared to adding fat. Though, it will be worth it in the long run.

Rivalus Clean Gainer calories and macros delivered will bring muscle gain. 

As I mentioned above, it has enough calories to put you in an optimal caloric surplus as long as you have a well-planned diet.

It’s better to gain 0.5 lb a week as long as it’s lean mass gain, rather than a 5 lb increase with all of it from fat. 

You would want to look like a Greek god or goddesses’ statue sculpted from clay, not a slab of sculpting clay.


If you need something with monstrous servings of calories, you can take a look at Mutant Mass Weight Gainer.

 It has 1100 calories per serving and delivers 56g of protein, 192g of carbs, and 12g of fat with 26g of EAAs and 12g of BCAAs. For the unfortunate hard-gainers, this might be a better choice.

Final Thoughts

This is a mass gainer that I would buy again and again. 

It gets the job done for me as a muscle-building supplement. Its ingredients are clean; and, it helps me go up in weight yet keep being lean.

It goes against the grain of most mass gainers, high-calorie and chock full of fillers. 

Rivalus Clean Gainer was made to supplement meals, not replace them. 

If you want to gain weight the right way and keep your health in check, then opt for the Rivalus Clean Gainer. 

While it could use a little more protein, you should be getting most of it from your meats, eggs, milk, and veggies anyway – natural and unprocessed.

Do you have the patience to build a lean and mean physique? If so, then the choice is now yours.
