This stuff is delicious and it REALLY works. What more could you ask for? (Posted on 1/31/12)

I haven't been able to use this very regularly yet on a workout schedule since I am currently busy with classes and such in college, however when mixed with milk, this shake tastes VERY good compared to other protein/gainer shakes that I've tried. It remains pretty thin and has not lead to bloating or cramps for me.

A solid product with good nutrients and great taste, but not a miracle gainer. (Posted on 1/31/12)

The scooper is twice as big as any other protein powder I have ever taken. It's not a big deal but I was surprised. It mixes well with water and ok with milk. The flavor is good, but it's slightly bland. I guess I didnt buy it to enjoy the flavor, I bought it to pack on mass. I have been taking it for about a week (twice a day) and I've gained about 5 pounds. Not a perfect product, but it's worth the money. (Posted on 1/31/12)

this stuff was amazing. the taste wasn't too spectacular, and the mixability even in a blender wasn't superb. even though, it got the job done. i gained 15 pounds and i'd say most of that, was muscle. i also made excellent gains in my strength while on this. my recovery was excellent on this product. the only reason why i give it a 4/5, was because of the mixability. believe me i will keep buying optimum nutrition products again though.

This stuff is pretty solid. Decent taste and pretty easy to mix with water without huge gross clumps (I use a shaker with a mixing metal ball thing inside). Overall, I'm a pretty "clean" eater meaning I don't like to have a lot of "additives" in what I eat. This product has a bunch of words I cannot pronounce so it's not the best thing is the world but it's a pretty clean protein mass gainer without all the creatine, etc. etc. If you are looking for a higher calorie protein shake to hopefully put on some lean mass, I would recommend it. Otherwise, just eat a heck of a lot more food. I don't have the time at the office to be eating all the time so this is a nice substitute between meals. (Posted on 1/31/12)

bought this to supplement my shakes really.. not trying to bulk up but thought i could use extra carbs/calories throughout the day. im still a med student so most mornings consists of a shake on the way to work - figure adding a scoop or two wouldn't hurt. as for the product itself, the container is a little larger than it needs to be since the powder didn't reach the top.

the taste is actually quite good considering what's in it - and that's the most positive thing i can say about it. (Posted on 1/31/12)

Very good taste. Effective & Good quality protein but it is quite expensive to buy. (Posted on 1/31/12)

I bought this for my lifting partner. The taste is good. This is Optimum Nutrition and I am going to leave it at that. I would only say one should use an empty protein container or two to hold it since the bag is not the best for that job. Also the scoop is a bit large I just used one from another Optimum Nutrition product. (Posted on 1/31/12)

I love this stuff. I've put on 13 lbs in 6 weeks (169 to 182) with no change in body fat percentage (18%). I use a scoop on rest days and 2 scoops on workout days. It is hard to eat 4,000 calories of just food each day and so this really gets the calories up, but not so much like gainers that have 1,000+ calories per serving.
Keep the gains coming! (Posted on 1/31/12)

I've probably tried ten different types of protein powder, and this is one of my favorites. The only negative is that it isn't "all natural." I mix it with 16 ounces of whole milk and add two ounces of olive oil for a calorie dense shake. Even with the oil and milk, it still mixes great without clumps. (Posted on 1/31/12)

Tastes good, and was cheap. only problem is scoop is huge compared to past gainers I've tried. Also I have been takin this fairly steady and not put on unwanted fat which is good. (Posted on 1/31/12)

Short and sweet:

Tried this stuff during a recent bulking cycle.

Doesn't make me feel bloated.

Ingredients are solid, it's not just stuffed with simple sugars.

Tastes great and fairly easy to mix compared to other brands.

It's a bit higher priced than some others but I think it's worth it. (Posted on 1/31/12)

I started using this product about a month ago. I have to see it really works. I gained about 6 pounds using this product and going to the gym 3 times a week. The chocolate taste is really good too. The only downside is I expirance mild stomach discoformt using this product, I'm usally sensitive to this kinds of products in general. (Posted on 1/31/12)

The gainer is pretty good, not to heavy like some other gainers I've had and didn't leave me feeling bloated at all. It also mixed fast in my shaker bottle with the milk I added to it. (Posted on 1/31/12)

This product is one of the best and proven, and you gain lean muscle. Digestion is almost perfect, no gas, no stomach-ache, without cramping. It contains much sugar as most of the winners of weight that only make you fat. Want a defined dense muscle? this is the product. For its price and size is the best buy so far. (Posted on 1/31/12)

Taste like pepto bismol in the form of powder! If youre gonna buy this product get it in a different flavor!! (Posted on 1/31/12)

This product is very much worth the money. I use it after my weight workouts and it has been very productive for my recovery. The only suggestion I would have to better this product is the quantity size that is needed for a whole scoop. The amount necessary for each scoop is quite large and so the product doesn't last very long. It becomes a little spendy, so if the price was lowered some then that would make up for the quantity used. (Posted on 1/31/12)

Pro complex gainer is good to go. Mixed well and tastes great. A+ (Posted on 1/31/12)

Seems to work great - I have effectively gained weight and muscle (with proper workout routine). Strange thing is now I tend to CRAVE this because it really is a great shake to have with you, especially if finding time to eat is a problem as in my case. (Posted on 1/31/12)

Tastes good, adds lean weight quick. Can't ask for much more. Only downside is the 5lb bag/container is only 14 servings so it can get a bit pricey if you use it every day (Posted on 1/31/12)

As an amateur/hobby bodybuilder, this single product has become a staple in my diet over the past 3 years. When I started getting serious about lifting again out of college, I had dropped to 145lbs from my previous high of 175lbs. My metabolism is fast, and I simply had trouble keeping up for a number of reasons: time, money, and the difficulty eating the calories I needed in solid foods. I then found this product, which has helped all three of those issues.

Pro Complex gainer is a very good gainer. I gained about 10 pounds in 2 months..mostly lean mass! But you need to work out regularly or else you would put on just weight. (Posted on 1/5/12)

This product is great if you're looking for a quality, easily-mixed, easily-digestable weight gainer. I've been lifting seriously for ten years and have used a number of products. This gainer is the best I have used thus far for a number of reasons:

1) It mixes easily in a shaker cup.
2) Protein is of much higher quality than those found in other gainers.
3) Good blend of essential vitamins and minerals.
4) Easy to digest!!
5) Allows room for food!!

After much research, several years ago I started using this muscle-gainer and have enjoyed it ever since. To me it is almost the perfect work-out / weight-lifting / energy / muscle-gaining drink. It has a great amount/ratio of carbs (85g ... only 5g in sugars), protein (60g .. several types), vitamins/minerals (usually only 20%-35% RDA ... some drinks put in 100% in many areas but I want to use a multi-vitamin), and taste (I have enjoyed my favorite banana, strawberry, and vanilla).
