Product Information



High Protein Weight Gain Powder

The true strength of weight gainers
Serious Weight gain requires serious calories. However, those who need the extra calories most often have the toughest time consuming enough of them. For many aspiring to be bigger, a highly-active metabolism, weaker appetite and on-the-run lifestyle can make it a real challenge to consume enough calories through whole foods alone. With Serious Mass™, you've got nothing to lose and lots to gain. We've consolidated 1250 calories, 50 grams of protein, 253 grams of carbohydrates, 25 vitamins & minerals, glutamine and creatine into every serving. It's time to stop thinking small; get serious - Serious Mass™.

Life changing confidence
I used to be so skinny and people would always tell me. After using this about 2 months I put on 20 pounds and constantly worked out my upper body. Everyone in my family and friends has noticed and said I looked a lot bigger and healthy and muscular (my chest and shoulders got bigger. I can finally wear short sleeve shirts and I feel like a whole new person.

Weight Gain
I love this product. When I first tried it I made it to the instructions on the package with milk it was too thick for my taste. So the next day I tried dividing the measurements 12oz milk and one scoop serious mass it taste much better. So I started doing this everyday only drinking 1/2 in the morning and the other 1/2 at night along with my meals or before so I still have my full serving per day. In 2 weeks I had gained 6 lbs. I also add fresh frozen strawberries to my blender. But I did notice when I used my blender the drink was really frothy so I would let it sit in the fridge for about 30 mins so the froth could go down. But recently I've tried just shaking it up and there is way less froth than the blender. Hope this was helpful.

I have lost weight due to an illness and needed to gain weight. I started using Serious Mass and have already gained 4 lbs. in 2 weeks. I actually enjoy drinking it as a shake. It takes great and doesn't have that chalky texture or taste like so many others. I will continue using it even after I reach my weight gain goal.

Is it possible to bulk up using mass gainer while you’re 13 yr old?
BashdiBALDI on Jun 1, 2018
BEST ANSWER: If by mass gainer you mean some sort of protein like whey‚ then yes you can bulk up. However since you are only 13 your body is still growing and your metabolism is still very high. You'll have to make sure to have a good healthy diet which is high in protein along with the mass gainer to make sure it works to its fullest potential. Foods such as nuts‚ fruits‚ berries‚ eggs‚ wild salmon not farm raised‚ leafy greens and chicken will be a great start for a healthy diet.
