I'm 5'7 and started at 149lbs and now I'm at 155/156lbsPros:-Saw about 8lbs of weight gain over almost a month which is good if you want a lean bulk, if you want to gain weight fast this is not the protein powder for you.-I'm a lot less sore from my workouts. I train as a power lifter and I've noticed significantly decreased DOMS.-minimal bloating and discomfort-The taste is really good. I prefer the vanilla though because it is easier to mix with other flavors.Cons:- Slow weight gain (again not meant to bulk you up fast but slow ,steady, and lean which in the long run is better so you have less fat to cut)-You should weigh your portions, the cup they provide will definitely not get you the serving size.

5.0 out of 5 stars Undersized Scooper - Great Gainer

E. · May 1, 2025

Great mass gainer, the best bang for your buck option out there. The wife loves it... but beware the scoop it comes with is not a full serving size (165g). Our average scoop (leveled) is about 120g and our heaping scoops (literally spilling out) were around 145g. So realistically you're sitting around 75%-88% of a serving person scoop which is roughly 80-175 calories less than expected and 7-15g less of protein.. might be marginal for some, but for my 110 lb wife, these margins are significant enough to skew her tracking data.Still a our preferred gainer, but will definitely need to adjust our input data or choose a new scooper. Jsyk.

Amazing! Tastes great and mixes super easy! Use milk instead of water for extra protein and calories and it tastes better too.

4.0 out of 5 stars Good stuff, not worth the price. (Just get Gold Standard Whey)

L.W. · May 31, 2025

Don’t get me wrong this stuff is great. Tastes great, good protein, good calories, etc… however if you’re on a bulk or just need the calories, you get more grams of protein per dollar with their Gold Standard Whey and then just blend in calorie dense foods, oats, etc into your protein shakes for the calories. You can tailor to your macros better that way anyways!

5.0 out of 5 stars ON Gainer Helped Turn My Life Around

N.c. · March 9, 2018

This product may have been almost a life saver for me. I have been using it for 10 years. I became seriously ill about a decade ago and was losing weight for unknown reasons. I am 5'10" and used to weigh in the mid 160s prior to my illness. Finally after dropping to the upper 120s my doctor recommended that I try drinking gainer shakes though he didn't mention this product in particular. I happened to mention my weight loss dilemma to my brother-in-law who pointed me to this product. So glad that he did. I started out drinking two servings per day and usually add a scoop of ice cream to it in the blender. It tastes fine to me with plain water but the ice cream makes the drink pleasingly colder. Anyhow, this put a stop to my nose diving weight and gradually pushed me into the low 130s which helped me feel some relief about my condition. About a year later I joined a gym and started working out with weights 3 times a week at least an hour each time, plus did some weight lifting at home in between. Slowly, slowly my weight raised into a more respectable mid 140s after about a year of weight lifting exercices plus this product 2X a day. Roughly 3 years later with my weight seemingly stuck in the 140s I decided to reduce it to one serving a day. I always monitor my weight and it remained basically the same. About a year ago I reduced use of this to a half serving, 6 days a week. I continue to work out at the gym and at home like usual. My upper body strength has increased especially my arms/biceps/triceps and pec muscles even at the reduced half serving of gainer plus my usual scoop of ice cream in the blender. I am happy to say my weight over the last 6 months has been lifted to almost the same level as I had prior to my illness. I am currently bumping up on the 160 lbs mark. So I have been using this for 10 years straight now plus going at my weight lifting for nearly that long a time. When I look in the mirror I grin at the results I have had over this LONG period of time. But I give a lot of credit to this gainer product and my doctors who initially encouraged me to use something like this many years back. I tend to drink mine now in the mid afternoon after my gym or home workouts and in between lunch and dinner. It does sometimes take away my appetite a bit if I drink it too close to dinner, especially back in the beginning when I was drinking two servings a day. Now at half a serving the appetite loss is much less of a problem. Will I ever stop using this altogether? Maybe, but not just yet. I do think there is a correlation between using this after a workout and building your muscle tissue so I may eternally use this at half strength based just on that. By the way, adding a scoop of ice cream to it in the blender not only makes it tastier and creamier but also adds some extra calories and calcium (I believe). The double chocolate is my favorite and adding some mint ice cream is wonderfully tasty. I think overall this product tastes great, even those times that I simply use plain water without anything more.

ES UNA PROTEÍNA QUE CONTIENE LOS SUPLEMENTOS ADECUADOS

5.0 out of 5 stars Optimum Nutrition Gainer vs. Critical Mass: My Take

J.B. · January 11, 2025

I’ve used Optimum Nutrition Gainer for a while, and it’s decent — it mixes well, tastes good, and delivers solid calories and protein for bulking. However, after trying Critical Mass, I have to say I’m switching sides.Critical Mass feels like a more complete package. The calorie-to-protein ratio is better, and it has more complex carbs that don’t leave me feeling heavy or bloated. Plus, the flavors are richer, and it’s not overly sweet like some other gainers, including ON.While ON Gainer is good for beginners, Critical Mass feels like the smarter choice for anyone looking for efficient gains without the crash or sugar overload. It’s just better suited to my needs and goals.

I use gold standard whey in the morning with creatine ...

It has helped me gain 15 lbs of muscle in 3 months while keeping the fat off. You need to eat clean and hit the weights hard with an occasional cardio session if you plan on using this product.

superb stuff well worth it

A.H. · March 14, 2015

Thus stuff in double chocolate flavour is delightful and easily the tastiest protein I've ever had. Highly recommend it if your trying to gain some quality mass but the tub won't last you long ya best bet is get the bigger tub or buy 2 of these 2kg ones. If you make this stuff with skimmed milk it'll top out at 800ish kcals add this to a decent balanced diet and you will get bigger :D

Amazing taste

Good mass builder with even better taste. Didn't get tired of it quickly.

great suppliment

T.C. · December 21, 2014

Great suppliment. Easy to digest and providing results.

Great quality but high cost per calorie

S. · September 23, 2015

Mixes very well (better than ON protein products) and has a very high protein to carb ratios plus tons of essential vitamins and minerals. Taste is quite good (Vanilla Custard) though nothing to rave about.Please note that the total calorie content per dosage is not the highest. It suits me fine, since at 640 calories it is just right to push a normal to slightly lower than maintenance diet into the bulking diet territory (so no complex re-computations needed) and has the right ratio of proteins, fats and carbs not to require re-computation of the rest of the diet. However, if you have very high caloric needs (if you are already a big guy and are struggling with diet targets of 3500+ calories or you are a true ectomorph), this may be an expensive proposition as you may need more than one scoop. At 14-17 scoops per package (depending on how high you heap your scoop) at almost 5K, this is very costly.If high protein content is not a requirment (or if you wish to further supplement with a protein powder) this is not the most cost effective way to gain mass. For pure quality and for medium size people with normal metabolism or slight ectomorphic characteristic, this is a great choice if price is not a consideration.
