I have been using Serious Mass for quite a while now and my weight has definitely improved. Great as a meal replacement, however I feel really bloated especially if I use two scoops.

I tend to use this after a gym session and on my days off I use one scoop with my meals.

A nice addition is peanut butter or a bit of honey.

Fantastic product!

I have always struggled to gain weight, even with the Pro Complex gainer. Although with Serious Mass I have gained 13 pounds of lean mass in 3 weeks of using this along side a not so strict diet and mixing only with water as well as training 6 days a week. I have about half of my second 5 pound bag left and i am hoping to gain and extra 6-8 pounds before the end of it.

I'd highly recommend this product to anyone wanting to gain weight. The chocolate flavor was delicious, however id avoid the strawberry flavor but that is just my personal opinion. ALWAYS ON!!

this is one of the best tasting mass gainer's i have used. Mixes easy also i always use a blender to get it smoother, i use 300ml of whole milk and 1 scoop and have 2-3 servings per day. It doesnt bloat me either like other one's i have tried. I will be usiong this for a long time the way its going. Plus you've got the bonus of the vitmains included.

Bought this in vanilla a number of times. Best tasting gainer on the market. Mixes really well with other food products such as peanut butter, nutella etc. needs a darn good shake for it to mix though. After using a range of other brands gainer, this is the only product i have bought again and again.

Serious mass is also good for people who want to gain weight without gaining fat or loose carbs. I am now on my 6th week of using Serious Mass. Of the 6 weeks, I did not take any in the 3rd & 4th week. Regardless of this, I gained 2 Kilos in weight. I don't mean to brag but these 2 Kilos are not fat, in fact my physique is better defined. I only used one scoop a day which is 167 gms. I used it to compliment my existing diet to add some extra calories. So the tub I bought in June has still got a few servings left as I write this review. Has issues with mixing though. I tried banana flavor which was good.

been using serious mass for a month now and have seen some good results in by weight gain, so overall, I'm pleased by the product. I have noticed that it didn't mix very well on some occasions, but I'm sure it could be sorted by diluting it more. But it's quality product for those who want to bulk up!
