Mass XXX
by Steve

I started using Mass XXX around 3 weeks ago. I am 5'6 and have weighed 125 - 130lbs for the last 15yrs. I have not been able to put on weight. I have a very fast metabolism. I started working out 2 weeks ago and have put on 10lbs in 3 weeks! Unbelievable! I put 3 scoops in 350ml of water and take this twice a day. If I workout I make sure that I drink one right after the workout. Seems to be working great for me. My goal is 150-160lbs by the summer. At this rate I will have no problem hitting that target.
I highly recommend this product!

How to gain weight
by Tim

I've been using this for a few weeks now and it helps me increase my strength but i have not gained any weight. I would like to gain at least 15 pounds during summer so is there any way that is possible?


The New Amp Mass XXX
by Alex

to make Vanilla taste unbeatable I use whole milk (whether you use whole milk or not is up to you) and more importantly I like to add Golden Grahams cereal. Put it all in a blender for about 15 seconds and your Golden! haha


when
by kenneth

i started using mass xxx about a week ago and i have to say i started seeing results but the things that confuses me is when to take it. it just says take twice daily, but is it an hour before i work our or during workout or even an hour afterwards


weight gain
by francesca

i've been using this product for about a couple of days now. hard to see results so soon. i'm not looking for any extreme body building weight gain, but want to go back to what i was and also add a little bit of muscle while working out.
@ nate. not sure if you'll read this, but i use orange juice with the chocolate flavour i bought. im not sure if anyone here likes it with orange juice here. but i feel that it gives it an electric flavour with the chocolate.


Amazing product
by Luis

Don't have to break your back to gain muscle, it doubles your work out time!


Mass XXX
by The Bone collector

Have been using Mass XXX for a couple years, back when it was only 52g of protein, and the new formula with 66g is unbeatable.Starting at 176lbs Nov.'09 to 218lbs 02-2010 with 1 hr routine 7 days a week no off time, I have found the full 7days keeps endurance and stamina at an all time high with massive weight gains.Definately RECCOMEND for beginners or for any one trying to accomplish great gains


Mass XXX
by Dylan

I have researched this product for high school football, just started it today. It taste good and I hope to see great results!


gain weight and moving up
by mikey

I took 2200 gold with creadrive and massxxx and was around 140 lbs and got up to 172lbs and have lifted for 2 1/2 hrs every weekday night after work from 9:30 till around midnight. It took me about 4-5 months, but slowly but surely I can vouch I know that I was able to do the pullover machine with one arm at 200lbs, biceps machine at 120lbs with one arm, and pectoral machine press one arm at 200lbs, leg press machine at 410 lbs one leg and so forth.


great for hard-gainers
by Barry

I have been in amateur bodybuilding for several years now, and two years ago my 12 year old son joined me in strength training. He was in his first season of football for his middle school's team. Using Mass XXX helped him not only add the body weight he needed, but was a key element in his incredible strength gains as well. In ONE season, he went from weighing 87 pounds, to 123 pounds, and is now benching 186!
Of course, it takes discipline and determination, but all that would be pointless without the proper balance of protein, carbohydrates, and essential fats needed to add solid muscle. I recommend Mass XXX for anyone SERIOUS about adding lean muscle fast.

Helped a Lot
by Mass

I really love this product I take 3 scoops of it when am done working out I workout 4 times a week I want to go to highschool and play football I weigh 150 pounds and am planning to be 170 pound of solid rock muscle.


Awesome product!!!
by Chris H.

I'm 17 years old and I'm 5 foot 9, and I've been taking this for about a month with WheyBolic Extreme 60 and both of them are absolutely amazing, they both taste great, of course i got the chocolate kind, which you can get at your local GNC Live Well, and i stated out at 125 pounds and now I'm at an outstanding 135 - 140 pounds, I put on 10 - 15 pounds in a month! I take WheyBolic (One scoop with 12 ounces of milk) when I wake up in the morning and again right before i eat dinner and I take Mass XXX (One scoop with 16 ounces of Milk) right before I go to bed. Also I workout 5 times a week. I will take this product as long as I can, as long as it is sold at GNC Live Well and by the time I'm 18 - 20 I would like to weigh anywhere from 230 - 245 pounds of solid rock hard muscle so I can be a Heavyweight Professional Wrestler. And also on another note I would suggest taking both of these products twice a day which is what I am about to start doing. And on One more Note I also take naNO X9 Hardcore, Creakic Hardcore, and Alpha Amino Prototype 216 which you can also find at GNC Live Well.


foster
by kevin

I purchased mass xxx every time I go to the USA I would like to know if I can buy anywhere in the UK its the best thing since sliced bread.


I put on wieght!
by Skinny dude

I'm about 5'10" and was 150 when I started lifting with my roomate who was a huge fitness freak. I busted my ass, got fit, but couldn't make gains. Got a tub of this, used it, stuff tasted great and to my absolute surprise it actually WORKED. I easily put on about 6 lbs of muscle - which is huge for someone who CAN NOT GAIN WEIGHT

fully recommend this to any other featherweights frustrated with lack of gains.


Amazing!
by Michael Floyd

This stuff works great. I had a full ride to Notre Dame and they said if i didnt get my weight back up the would revoke my scholarship. I took about every legal produst out there and nothing happened. I was doing some research and found GNC Mass XXX i took it for about 2 months and i have gained around 25 lbs. And its all muscle. Plus this stuff tastes amazing, get the Chocolate flavor and mix it in a Blender ball shaker w/ 2% chocolate milk and you will gain at least 10 lbs per 6 pound tub!!!


Sales guy
by Forrest

I am really liking the mass XXX that I got; two containers down right now and I can still drink it. One note though; you've gotta use a blender for this stuff guys. Stir all you want, those chunks aren't going anywhere unless you shake the hell out of the mix in a bottle, or blend it. I recommend the latter. Don't just drink this stuff and sit on the couch. Work out, break down the muscle, and THEN take down three to five scoops contingent on how many sets you did. I'm only doing two sets because I am working out five days a week, but a supplement really helps. You still need to eat three meals a day, too.


Mass xxx
by New buyer

Well if you lift weights and then take it after your workout before you go to bed or when you wake up then you should gain muscle but if you just want to gain weight, take the mass xxx and don't work out.


mass xxx
by Colton

i am 5'9" and my weight right now is 180 even... will this Mass XXX help gain weight to my body and will it help me gain muscle size?


serious gains
by scott

I have a very fast metabolism and ive tried tons of different weight gainers and i think this is one of the best in my opinion.ive been taking mass xxx for the past 2 and a half months now and have already put on 9lbs of muscle.ive never had such gains of any gainer before.ill be sticking with this product for a little while for sure.


Serving size and taste
by New buyer: chocolate mass xxx

I think most of the protein tastes sick but chocolate is the way to go. Strawberry seemed to leave a few chunks even after well mixing. If you like yoohoo or hot chocolate then you should definetally go for chocolate. It tells you to put 4 scoops in 16 ounces but I do half that amount but in the same sitting meaning put 8 ounces of water or milk with 2 scoops, blend for 20 seconds then do that a second time to get the full effect and amount


Fast metabolism
by New buyer: chocolate mass xxx

I have a really fast metabolism and nothing has seemed to help me gain weight. I was taking wheybolic extreme 60 which is a good protein boost and now I have mass xxx which has helped me get those extra calories I been missing. I noticed after a day of 4 scoops that it makes you feel really hungry and energized


MASS XXX
by Luny

Well I am looking to try and gain weight and to get my body up there and am starting on this. Is this something good to start working out with or should I start with something with less calories?


a huge pump
by Alan

I remember my first time trying it, it gave so of energy, I was hyper, I ran super fast. my friends were surprised how fast I was.

mass xxx strawberry

Cookies and Cream
by Jonathan

I bought the cookies and cream flavor i havent read any reviews of anyone else buying it so i think its new...it tastes very good with milk...i didnt like the waste with water but its very good with milk i recomend the flavor


Mass xxx
by Jacob

Okay, I am a 16 year old sophmore and I started taking mass xxx about a month or to ago and I am taking it for football purposes BENZIE HUSKIES HELL YA!!!! but in those 1 or to months ive seriously gained about 35 pounds on my max bench I went from 225 to 265 fairly quickly so ya it is good stuff well worth 60$


When, and how much
by thesheetster

I've been taking it for about 4 months now and have found that taking 2 scoops 45 minutes before my workout and then the other 2 scoops about 30 minutes after my workout works well. then your body isnt trying to absorb it all at once. I like to use biking water bottles to make mine in. just add milk or water and shake the hell out of it, no chunks. You can make them earlier and take them with you too.


mass xxx
by you dawg its tha weight lifting king so watch out cause i bench 250 pnk ahaha

I heard this product was really good in its performance. I am still awaiting to see how it works with me. Update later.



Thanks I just bought the chocolate one
by New user

It's alright I'm not sure how much to use though...


mass xxx
by protien king

If you shake up half the amount first and then add the second half that has worked pretty well for me to get rid of chunks


get rid of the chunks
by urban

mix it in a regular blender for 20-30 seconds, with milk or water, or both+ the mix, goes down nice and smooth with no chunks. Vanillas best flavor in my opinion. blender 15 bucks at walmart. chunky and nasty when you attempt to mix it with a spoon.


before or after work our
by Matt

When u take Mass xxx should u take before or after u work out to get better resualts or does it matter??


Nasty, but helpful
by Modus

This stuff has a nauseating taste. While digesting it, I feel weird for an hour afterward. Other than that, though, it has everything my body needs. I take one scoop a day on top of whatever other protein supplement I'm taking.


get the chunks out
by tellemboutme

too many scoops....only 1 scoop per 16 ounces of water or 2% milk


mass xxx
by ty_04

I like this stuff a lot and its working but its really chunky when i mix it, ive been following the directions 4 scoops in 16 oz of water can anyone give me some tips on how to not make it so chunky?


Gnc for me
by Cm12

In just a few weeks I have seen great gains using mass xxx. A lot of you are saying that you take it after working out. I've been taking it just before bed and as I said, it works great. The chocolate flavor tastes awful though.


Good Stuff
by Viper

Very good stuff. Been taking this 6 months and the results are more and more noticeable.


stuff works
by Mike

great product. first day i used it i was into my 2nd week of working out and i went to the gym 45 min. after taking it and i move up atleast ten lbs. on everything i did. you can really feel the energy it provides. it is a bit pricey but you get what you pay for. i lucked out on a sale getting the 12lb bucket size for only $60


mass xxx to expensive
by warrant officer

This product is extremely expensive. It cost 51 dollars in the store I wish they could lower the price.

MASS XXX
by Jeremy

I was 5 11 and 144 pounds when i decided to start working out and using this product. in one month i put on 20 pounds. and now in the fourth month i have put on 30 pounds. i continue to use it because its giving me the results i am looking for.


works
by jonas

Hey, I've have just finished my first 6lb container of XXX and I have already gained weight. Lately I haven't been eating that much and have been keeping the weight on without loosing any. Before I was using some MHP but I have already gotten better gains from this stuff. I'm buying more tomorrow. Good stuff and tastes awesome with only water! It is also the best tasting protein powder I have tried.


A++
by Tiff

Pro Performance Mass XXX is definitely by far a great product. If you need help gaining muscle this is the product for you. I can't get enough calories during the day and this supplement really helps. I gained about 8-10 pounds in one month on a light work out schedule. It doesn't taste the greatest but its will worth it. The price isn't bad its $40.00 in most stores sometimes cheaper! This product is the best!


Speed up your weight gain
by ihscav99

This is a great product if you need some extra help with putting on the muscle. Like most people, I can't eat enough calories during the course of the day and a supplement like this really helps. I was able to gain 7 lbs in a month on a relatively light workout schedule. The only negative is that it does not taste the greatest.


Satisfied
by domZ

I have never exactly been the bulky type, and I wanted to start on my new image for the beach this year. This was a key product in helping sculpt the new me! One scoop every day before I work out and I feel and can see a significant difference!


Major poundage
by Brian

Not many people are in my predicament of needing to gain weight, but if you are, this powder is the healthiest way I know of packing on the calories without an excess of ingredients you don’t want, like unhealthy fat and carbs. This container lasts a long time and is a bargain for the price.


Happy Customer
by Stacy

Pro Performance® Mass XXX really helped my husband bulk up. It has loads of calories and is a pretty good buy compared to the other stuff out there. Great product overall.


Good product
by Dave

One of the guys that I workout with uses Mass XXX and it has worked extremely well for him. This is a cheap and easy way to get the extra calories that you might need. Plus, GNC always seems to have quality products. One word of caution, before you use this, keep in mind that this adds a significant amount of calories, so if you take this and aren't working out enough, you will just put on weight.

ways to make it taste better
by nate

I've been taking this product for a while and its a little gross to pound back. Does anyone mix it with other things to make it taste better?


Mass XXX
by Yuvaraaj

I have been using Optimum Nutrition Whey protein Gold standard for the past 2 months and i wanted to go for a protein with some muscle mass. I went to the GNC store near by and they suggested the Masss XXX.
Iam around 176 cms and 72 kgs approximately. I never wanted to gain more weight rather i wanted to reduce by fat content in the body and grow more muscles ( gain lean muscle mass). i am using Mass XXX for the past 4 days and iam feeling more sleepy after an hour i use it. First day i took 2 scoops in the morning and i couldnt work , i felt damn sleepy. From second day iam taking 2 1/2 scoops after workout in the evening. I can feel the heat coming from the inside of my body and iam sleeping for more than 8 hourse. I have never felt this behaviour with ON whey protein. is this Normal? Will this product help me in reducing fat and build more muscles?



good stuff
by jeff

I use the cookies and cream flavor. It tastes pretty good and I gained 3 pounds in one week. If your trying to gain mass, this is definitely for you.


For Ryan
by Matt

This is for Ryan, eat everything in sight and pound the Mass XXX three times a day, after you lift, and bed time. Lift hard and eat a lot, no matter if your not hungry, force the food down. Do this and you will hit your goal before football, with out a doubt.


Mass xxx
by Devonte Miller

This stuff works the best if blended. I was 160 lbs when wrestling season started, and went up to 171 lbs after 2 months all muscle. It also helps eating right and eating health suplements. Thanks GNC!

I'm 17 years old im 5.9 an i weight 146 pounds... what steps do I need to take when drinking mass XXX? I would appreciate any kind of advice. Thank you! hate4life_13@yahoo.com


Mass xxx
by Ryan

I've been taking mass xxx for about a week now and still didn't see any improvement. I am taking it because I want to play football but I only weigh about 120lbs as a freshman in high school. I need to gain weight fast and I work out everyday and I even participate at track. I put about 2 scoops of the powder and blend it with 2% milk everyday but I only take one cup. Please tell me what I am doing wrong I really need help gaining weight. I need to at least weigh about 135 or 150 lbs before football season starts and that will be here in about 2 months.
