Mutant Mass is a serious weight gainer supplement, designed for hard working athletes who demand power, absolute size and all out strength. Mutant Mass weight gainer is packed with everything you need to pack on mass. If anyone is looking to put on some serious mass, we would point them toward this product. It's that effective as a big bag muscle gainer!
Every 260g serving of Mutant Mass (with water) delivers 52 grams of muscle-building protein featuring Mutant Pro's Multi-Staged 10 Protein Matrix, and 1,060 calories to help increase your weight when combined with your normal diet. The unique protein matrix found in Mutant Mass supplies the body with 10 complete protein sources, which provides an immediate and long-lasting increase in protein synthesis! When you combine the powerful protein matrix with the other essential anabolic nutrients found in Mutant Mass, you have the ultimate formula for rapid gains in serious mass!
Your body needs a surplus of calories to grow! However, you must ensure that you're taking in quality calories and nutrients if you expect to pack on quality mass. Scientific research shows that the addition of 1000 to 2000 calories per day to your regular diet and training program can result in significant gains in lean mass and strength. But you can't just get those extra calories from any old source or else you'll end up gaining more fat mass than muscle mass. Mutant Mass is scientifically designed to stimulate rapid gains in lean mass and delivers the perfect combination of protein, carbs, lean fats and other anabolic nutrients needed for maximum muscle growth, strength and recovery. By using Mutant Mass you can rest assured you'll quickly make monstrous gains in quality mass!
Let's take a look at each matrix in the MUTANT MASS formula and see what it does:
You can use Mutant Mass anytime throughout the day, but of course the best time would be when your body craves an extra surge of muscle-building calories and nutrients. Simply shake or mix 4 scoops of Mutant Mass with 480-960 ml (16-32 fl oz) of water or milk. To ensure maximum growth and recovery, many drink one Mutant Mass shake first thing in the morning, and a second immediately after training.
Some people take their first Mutant Mass shake in the morning but take 2 or 3 scoops instead of 4 and have regular diet throughout the day. Or, 2 or 3 scoops of Mutant Mass 2 hours prior to training and 4 scoops after with meal. On non-training days they take it in the morning and often in the evening as well. There are a variety of different ways to take Mutant Mass weight gainer. Let us know how you prefer to take your Mutant Mass weight gainer, and if you have any opinions as to how you take it.

This is the most effective weight gainer and yet not that expensive. Gives you the biggest bang for the buck. No question about that. I bet this is the best seller in Canada as almost everyone i know takes this.

This is the most economical weight gainer in my opinion, especially when this site runs cashback promo. i don't experience gas issues like others claim, i give it a 9/10 because i have to use the blender to mix it. otherwise it would have been a 10 out of 10

I have no gas issues, thank goodness. If it gives you a lot of gas then take some digestive enzymes from Allmax. My brother takes them and he says it's been extremely helpful in gas prevention. Well, he farts even when he's not taking the Mutant Mass though MUAHAHAHAHAHAHHA! I would stay away from Strawberry, I recommend Triple Chocolate

this product makes you fart like crazy, like never before done LOL. I couldn't go to the office because of constant gas and fart. Tastes good and I gain weight, but I can't sacrifice my work days. Average 5 points.

Whenever I try a weight gainer supplement I look for 3 things:
1) RIGHT amount of good-quality calorie, 2) energy I get off of it, and 3) taste and mixability. Mutant Mass delivers on all three points.
1) this weight gainer is not for wusses, I mean I train A LOT. and this calorie-dense formula helps me to keep conquering each day. And Mutant Mass uses good protein sources so I seem to be gaining, not fat mass, but muscle mass. That's great.
2) Mutant Mass incorporates maltodextrin (a complex carb source) and this assists me with a constant supply of energy after my workouts
3) My favourite flavours are Cookies & Cream and Triple Chocolate. No blah-taste from this product in my opinion. The powder quickly dissolves in cold water, which is a huge point.
In the weight gainer category, Mutant Mass has my vote.
