7 Reasons Hardgainers Are Adding Protein Power to Their Mass Gainer

You drink your shake and sit there bloated for hours. Your next meal gets pushed back. By the end of the day you ate less than you would have without the mass gainer. Protein Power fixes the bloat so you can eat more often and absorb more from every meal.

Your Mass Gainer Is 60-70% Maltodextrin. A Review of 70 Clinical Trials Found It Actively Disrupts Your Gut

A systematic review of 70 clinical trials found maltodextrin induced measurable gut disruption in 63.9% of them. That is the ingredient making up most of your mass gainer by weight. Protein Power's 6 enzymes break it down before it reaches your gut meaning less bloat, more meals, and more weight gained from the same shake.

68% of Adults Can't Fully Digest the Dairy in Your Mass Gainer. The Maltodextrin Hits on Top of That

A meta-analysis of 62,910 people found 68% of adults globally cannot fully digest lactose. Your mass gainer uses whey concentrate, which is loaded with it. Protein Power's Lactase breaks down the dairy while the other 5 enzymes handle the maltodextrin meaning your gut fights one less battle and the calories go to weight on the scale.

WHAT TRAINERS SAY
Ethan Silva

“Mass gainer is supposed to help you eat more. For most of the guys I train, it does the opposite. They drink the shake, bloat for three hours, and skip their next meal. Fix the digestion first and mass gainer actually does its job.”

The Bloat After Your Shake Pushes Your Next Meal Back by Hours. You End Up Eating Less Than if You Skipped the Gainer

A double-blind crossover trial found enzyme supplements reduced bloating from high-calorie meals. A separate placebo-controlled trial found a multi-enzyme blend, like Protein Power, cut bloat by 68% in 90 minutes. Meaning you eat again sooner, hit more meals per day, and gain weight faster.

Up to 40% of the Protein in Your Shake Passes Through Without Your Body Using It. That Is Real Money Wasted

Up to 40% of dietary protein never reaches your muscles. Every $60 tub of mass gainer you buy, your body wastes roughly $24 of it. Protein Power closes that gap meaning more of every shake reaches your muscles and shows up on the scale.

What Mass Gainer Users Say About Protein Power

Went through Serious Mass, Dymatize, and Mutant Mass. Same bloat every time. Started taking Protein Power before my shake about a month ago and the bloat is gone. I'm still using the same mass gainer and am up 6lbs.

I was two weeks away from giving up on mass gainers completely. The gas was embarrassing and I was not gaining weight anyway. A buddy told me to try Protein Power before my shake and within a week I could actually eat my next meal on schedule. Scale started moving for the first time in months.

My training partner kept telling me to try this. I thought it was another supplement gimmick. Two weeks in and I have zero bloat after my shake. I eat dinner an hour later with no issues. I gained weight faster in the last month than the previous three combined.

A Study of 21 Men Found Digestive Enzymes Put 3.5x More Protein From the Same Shake Into the Bloodstream

A study of 21 men found adding digestive enzymes to the same 50g whey shake increased amino acid delivery by 220-350%. Same shake, same dose, 3.5x more reaching your muscles. Meaning more of every mass gainer shake goes to muscle and weight on the scale.

How it works

Eat More During Meals

Food is broken down faster, so it doesn’t sit and build up as quickly. This reduces the feeling of getting full early and makes it easier to keep eating.

Eat More Frequently

With less leftover buildup after eating, meals move through more cleanly. This reduces the heavy, bloated feeling that delays your next meal.

Absorb More From Your Food

Breaking food down further allows more nutrients—especially protein—to be used instead of passing through. This increases how much you get from each meal and supports weight gain over time.

Benefits after 1 week

week 1+

You may notice: Protein breaks down easier. More calories are absorbed.

week 4+

You may notice: Bloating and the full feeling starts to fade. Your eating more, more frequently.

week 8+

You may notice: The scale starts going up and training shows more. Eating more finally equals gaining more.

The costs below reflect a typical month for a man eating 3,500+ calories a day to gain size. In a 2021 paper in Global Food Security, Moughan et al. found that under normal digestive conditions, up to 40% of dietary protein leaves the body unabsorbed. Effectively wasting calories and money.

I know how to bulk. I have been bodybuilding for years. Protein Power made it easier to stay in a surplus without that overly bloated feeling, so I could eat more frequently.

Every hardgainer I've worked with eats plenty — the problem is their body doesn't hold onto it. This is the first thing I've recommended that actually goes after that instead of just telling them to eat more.

Bulking sounds easy until you actually have to eat that much — I'd be bloated from my last meal before and stuffed while eating my next one Protein Power made eating 10x easier.

I was in Zero Høur’s independent study for three months. At first, I didn’t notice much—but after two weeks, eating got easier and the bloated feeling went away. By the end, I’d gained almost 17 pounds (174 to 191).

As a powerlifter, my protein needs are insane, 250g+ daily. The problem wasn't appetite, it was digestion. I'd feel too full halfway through meals to finish them. Protein Power helped me actually process what I'm eating. Less bloat during meals, better absorption. I'm finally able to eat without force feeding myself.

FAQS

why didn't other supplements work for me?

Most supplements add more calories and protein. They don't fix why your body isn't absorbing what you're already eating. That's the actual problem — and that's what Protein Power is made for.

How is this different from a mass gainer that already has enzymes?

The enzyme blends inside mass gainers are underdosed. Protein Power has 6 enzymes and 3 probiotics at doses that match what was used in clinical research. And it works with whatever you already take.

What are enzymes, why do i need them?

Enzymes are natural proteins that help your body break down food and absorb nutrients. Protein Power supplies targeted enzymes to improve protein absorption and utilization.

How long do results take?

week 1+

You may notice: Protein breaks down easier. More calories are absorbed.

week 4+

You may notice: Bloating and the full feeling starts to fade. Your eating more, more frequently.

week 8+

You may notice: The scale starts going up and training shows more. Eating more finally equals gaining more.

Is there a money back guarantee?

Yes. First subscription orders are covered by a 90-day money back guarantee.

Can I take Protein power with other supplements?

Yes — and it makes them work better. The digestive enzymes help your body absorb more from everything you're already taking.

will this cause stomach problems?

No. Protein Power uses natural digestive enzymes and probiotics that are already found in your body. It works with your digestion, not against it.
