High quality calorie gainer / meal replacement
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. VALUE - At approximately $2.25 a serving (when using subscribe and save), this is one of the cheapest quality 650 calorie meals you can provide your body with. I found this to be much more cost effective than trying to put together my own meal. Thanks to Amazon's subscribe and save, the prices compete with the other bigger online supplement retailers and I don't have to worry about re-ordering. PERFORMANCE - I can drink an entire serving in 2-5 minutes without feeling bloated/sick (taste ranges from acceptable to good - banana cream and vanilla are must tries). I have one serving every morning, and one at some point after my workout and before bed. This accounts for 1300 of my 3500 daily calorie intake. For me, without the aid of liquid weight gainers - it would be impossible to achieve my calorie goals and gain lean mass. I especially would struggle in the morning -- I often don't have time to prepare a good meal, and have trouble eating too many solid foods first thing in the morning. Also - understand that while 60 grams of protein a serving may seem like too much, this is not 60 grams of pure whey protein that is metabolized very quickly. It is packed with 7 sources of protein (faster and slower metabolized proteins) so it takes several hours for your body to metabolize the protein. RESULTS - When used with a high quality, high calorie diet and proper lifting routine - this product can help you achieve your daily calorie requirements and consequently gains in lean mass. I have used this product to raise my weight from 145lbs to 187lbs while keeping body fat under 8%. Highly recommend this product over cheaper gainers with more sugars/poorer quality calories. FYI - If you have the time, I recommend following the blending instructions provided. However, if you are short on time - a shaker bottle is best. The blender mixes the product so well, that it will take you 2-3x longer to drink since the volume of product is increased just due to being "frothy" from the blender. While the blender taste cannot be beat (and less water can be used to get good mixing results), a high quality shaker bottle does work well for this stuff as well with 20-40 seconds of shaking and the correct amount of water. You sacrifice taste for a shake that takes less time to drink.

Great product
Excellent protein powder that’s helped me put on extra pounds to build muscle. I use it daily and really enjoy the taste. One container lasts a little over a month, making it a solid value. Recommended

SO GOODD!
Usually never do reviews but this weight gainer is pretty good. I'm 5'7 and started at 149lbs and now I'm at 155/156lbs Pros: -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.

Awesome Product
I have been using Optimum Nutrition Pro Gainer for a few months now, and I must say, it has exceeded my expectations as a muscle-building supplement. This review is based on my personal experience, and I believe it deserves a solid four-star rating. I’ve managed to with workouts to increase my weight from 195lbs to 220lbs. First and foremost, the taste of this protein powder is outstanding. I have tried various flavors, and each one has been delicious. Whether it's chocolate, vanilla, or strawberry, the Pro Gainer always delivers a satisfying and enjoyable experience. I appreciate that Optimum Nutrition pays attention to the taste, as it can often be a struggle to consume protein shakes consistently. With Pro Gainer, it is easier than the standard protein shake. The nutritional profile of Pro Gainer is impressive. Packed with high-quality proteins, complex carbohydrates, and healthy fats, it provides a balanced blend of macronutrients that are essential for muscle recovery and growth. I found that this supplement helped me meet my daily caloric and protein intake goals, making it easier to fuel my workouts and promote muscle gains. The added vitamins and minerals are also a bonus, contributing to overall health and well-being. Mixability is another area where Pro Gainer shines. Unlike some other protein powders I've tried in the past, this one dissolves easily and smoothly in both water and milk. No clumps, no gritty texture—just a creamy and consistent shake every time. This is especially important for me when I'm on the go and need a quick and hassle-free option. I’d rate its dissolvability as average to above average in a shaker, but have been using a turbo mixer for better results and consistency. The only reason I deducted one star is the price. Optimum Nutrition Pro Gainer is definitely on the pricier side compared to other mass gainers on the market. However, considering the quality of the ingredients and the results I've seen, I believe it's worth the investment. The cost might be a deterrent for some, but if you prioritize quality and effectiveness, Pro Gainer delivers on its promises. In summary, Optimum Nutrition Pro Gainer is an excellent choice for anyone looking to build lean muscle mass and support their fitness goals. With its fantastic taste, impressive nutritional profile, and superior mixability, it stands out among its competitors. While it might be a bit more expensive, the results make it worth every penny. I highly recommend giving it a try and experiencing the benefits first-hand.

I use gold standard whey in the morning with creatine and I only use pro gainer after I work out. 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.

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

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.
