NOT Recommended I bought this a while back in my attempts to gain weight. I found that this, and most mass gainers on the market are loaded with sugars and are not a good way to gain weight at all. Getting the bulks of my calories from clean food is the way to go. In times that I need something quick I make my own homemade shakes. Much cheaper and more effective. I'll be honest, GNC's products are all wayyy over priced too. I wouldn't purchase from them ever again now that I know better.

Recommended Overall Great product! great gains, quick muscle building, it did pack a little more fat than the usual proteins i have tried but a lot of cardio took care of that. I Have gone through about six tubs of this product, the chocolate and cookies and cream are the best, but i'm not a fan of vanilla and strawberry.

Maybe Recommended I've been on Mass XXX for about a 2 weeks now, and i have finished the tube unfortunately. Although i have seen some improvement in my strength but generally not in the physical appearance. I mean isn't that where we are all going for? My point being for this review is a protein supplement truly enough to gain muscle or is there other supplement required in order to gain muscle in an ideal time frame. By the way, it's make on killer protein shake with milk and bananas with the vanilla flavor...

2 weeks is not enough time for your body to build as much muscle as you think it would. I'd say to continue for about 8-12 weeks, that should be more than enough time to see results not just in the mirror but in your lifts as well.

Recommended By far my favorite post workout protein shake. I have tried all kinds of post workout shakes, and for some reason i always had headaches with them. I have probably gone through 20 jugs of this stuff. It is a little pricey, but if you have a gold card and get it at the beginning of the month you can get 12 pounds for about $70 which isnt that bad. I always do a half serving with whole milk though because anymore than that i feel sick. And always get chocolate, the other flavors are really chalky for some reason.

Recommended I went from 137 lbs to 144 and i am almost done with my first tub. The only thing i did not like about this was how long it lasted. When you get 6lbs of it i expected it to last at least two months. But i have just finished my 3rd week of it and i am almost out, i am expected to be out before a month. But i did like the results. My strength has gone up and i am finally gaining weight, quickly. Which is what i need.

sorry i didnt see you posted on mine when i just responded to yours lol, but i think this is a good weight gainer, i couldnt gain anything either. And i would even eat a lot of calories like you did, i think as long as you keep a good workout routine (mine was 6 times a week) and take the product consistently, then you will gain weight. Also eat good things for you, dont eat chips and candy and soda like crazy to try to gain weight lol, then you will just get all of the weight it the belly. Good luck with your weight gain, let me know your results.

ya you could do that but honestly i wouldnt, the weeks i would take 4 scoops a day i would gain 2-3 lbs in the week, so i would imagine some of that was fat, and if you took 8 scoops a day i could see a lot of fat, and also the serving size is 14 (1 serving= 4 scoops it says). which is awful, if you have 8 scoops a day it will last you a week lol

yes, you should at least gain 5-10 lbs if you stay with it, and stay with a workout routine. Honestly, i did not count the calories i was taking in, but i would eat a decent amount every two hours. I would imagine 3000-3500 would do the trick but i am not sure.

Recommended im on my second tub of mass xxx and it definately works. i took my first tub about 3 months ago, im 5'9 and i went from 138 lbs to 145. my bench went from 205 to 215 in 2 weeks. i just started taking a second tub of it again about 2 weeks ago and i went from 148 to 152 and my bench went from 225 to 235. i take this stuff differently then the label says to because it doesnt really make sense to take it how the label says anyways. i take 2 scoops of it rather than 4 because that gives you about 33 grams of protein plus i take it in 14 ounces of milk which puts it a little over 40 grams of protein in my shake and the body can only absorb 40 grams of protein anyways so its a waste to do anymore to me. me and my friend baught 2 tubs on a buy one get one half off sale and the price came out to be about 34 bucks each which is an awesome deal i think. great stuff!

you do of course realize that the body doesn't even take in 40 grams of protein at a time, manybe around 20, idk where u got 40 from. And i hope you realize that not all the protein you intake is absorbed into the muscle. alot of it is wasted. Thats y nitric oxide, and whey Protein Isolate, is the real way to go. id suggest MRI Pro-NOS, it worked great for me. (only order the chocolate one, the berry one takes like ass)

To superman69: Mass XXX is a protein blend, meaning that it's made up of various types of proteins with varying absorption rates. Due the varying absorption rates, Jaycon actually can absorb most of those 40 grams, since the protein will be absorbed over time and not all at once.

The body can absorb between 30 and 40, it depends on the person and types of protein. Plus, this supp is a gainer, im trying to get the most calories and protein i can without going overboard. I take a whey protein post workout so i dont use my gainer for that. I use my gainer as a gainer and it works for me the way i take.

Hey amar, this is a solid gainer, take 2 shakes a day, 2 scoops in 16 ounces of milk, one mid morning and one before bed. If you cant gain weight doing what i just said, you need to evaluate what you are eating during the day and your workouts. For workouts, make sure your hitting the big 3 (bench, deadlifts, and squats) and keep the reps under 8 for those lifts. I recommend pyramids and drop sets. You gotta push heavy weights if you want to grow and those workouts are the best for growth. I never deadlifted consistently until about 6 months ago and since then in addition to taking some supplements, Ive put on around 25-30lbs. Good luck bro.

Maybe Recommended I'va had vanilla taste uh, not bad bud not good. i did realize some gain in this nothing huge but i gained a few pounds in muscel mass. it is better then whey protein. it does not mix with milk easily though i had to put it into a shake. over all it works pretty well.
