Overall really enjoy the product. It gets most of the carbs I need to replace and at 50g of protein per serving, it helps fill your extra calorie needs. I don't like that it only comes with 8 servings for the price at 6 lbs. *

This mass gainer goes really well with a banana and some peanut butter. It makes a really smooth shake. The powder alone with some milk doesn't taste as good! I've noticed some weight gain while using this gainer! I plan on purchasing again. *

Being as busy as I am, this stuff is great for on the go, when I cant cook. Gotta keep the protein synthases going. Even Sunday is bulk cook day, sometimes I can't make it home or wherever. I am wondering why so much sugar though??? Taste isn't bad considering what your drinking. *

The taste is great!! And when i have a shake early in the morning with breakfast I typically have more energy towards the end of the day when I can work out. These really help with people may not take in enough calories to really make significant Gainzzz. *

I have a hard time bulking so purchased this to try and help me keep on the weight if I take this stuff everyday it seems to help I have gained about 5 pounds after using this for about a month. Chocolate peanut butter does not taste very good. *

I have ordered this product in Vanilla several times. Love it, taste is good and very easy to mix with my Shaker. i don't even need to use a blinder. I mix it with Water, I did have that Milk would mess up my stomach and have me racing to the bathroom. Since the switch to Water, No issues. not a big fan of eating, so have found these to be a great meal replacement with Lots of calories.
Hope this helps *

Great weight gainer. Gained five pounds in the first week. Two scoops is a little much for me to take at one time so I just did one scoop three times a day. Taste was pretty good as I mixed with strawberries or a banana in occasion. Great product for me. *

Good protein and calories to help fuel muscle. Scoop servings are big but i recomend just doing half of a serving if you're just starting out. Chocolate peanut butter is good. Chocolate chocolate is my favorite flavor. *

I grabbed this on sale, but I'd buy it full price if necessary. I absolutely love Serious Mass. I've been working out for over a year, and haven't really noticed any serious gains until I purchased this. I'm pretty busy with when I'm able to eat and add extra calories, and Serious Mass makes it pretty easy. I suggest purchasing a blender bottle because the powder can get kind of clumpy. Overall, fantastic product. *

I love this stuff, it tastes great. I take 3 times throughout the course of a day if I'm really trying to bulk up. Once with breakfast, once between lunch and dinner, and one more before bed. I usually can't sleep if I have protein in my stomach but this stuff gives me no problems at all. Works great too. Better for bulking season, but if you do some light cardio and abs, you can keep things under control. *

Great product used it many times it's good for post-workout recovery very filling the taste is good but there's just no way that you can put two scoops and 8 or 10 ounces of water it would be like cement so break it up into a couple of scoops of a day to fulfill your protein needs *

Great product! I take 1/2 a serving in the morning and the other 1/2 at night. The taste is amazing and will be using for a long time! Only reason it's not a 5 is because of how big the servings are but it's not that big a deal! Enjoy! *
