Banana Cream Pie
10/10

I bought this product to help me gain more muscle, as I have hit a plateau. After a year of working out consistently (4-5 days a week) I went from weighing 120 lbs. to being a 170 lbs. lean machine. Since I hit 170 lbs. I stopped gaining weight. I had been solely relying on food to help me gain muscle and weight. I was at the point I had to consume SO much food that it was too painful for my stomach to handle every day. I bought Pro Gainer so I can get the extra calories/protien/and nutrition I need without having to give myself a stomach ache from trying to overeat to give myself the same nutrients. This product has NO EFFECT on my stomach, no bloating, and i don't feel stuffed after drinking this stuff. I bought banana cream flavor it is decent alone but adding real bananas and strawberries along with milk and yogurt and blending it in a blender, makes it taste like a treat! If you just have a blender bottle it will mix just fine, the consistency is very thin and smooth. I prefer this consistency because its easy to drink it fast and since its thin it doesn't sit in your stomach. The price is a bit high but I belive you get you moneys worth in the end. 9/10

great product. easy to mix, nice to drink and solid profile i had the chocolate and vanilla over the years and keep enjoying it only complain is that ON should launch a natural line for the gainer as well (as they do for the whey).

This is by far the best mass gainer I have tried! It is super clean and tastes great! I recommend this product to anyone who wants to put on quality size.

Been using this for about 10 weeks now. Loved the double chocolate, fantastic results. This last time around I thought I would try Cookies and Cream, and I hate it. I find myself adding extra water to water down the flavour. I would not recommend it. The product itself definitely 10/10.

This gainer is totally amazing and one of my favorites so far. Great taste, easy to mix and very effective. If you want a clean bulk (obviously the diet is the most important) try this gainer, it worth it :)

I ordered this product because it met the needs of my macros and I was coming up short with my calories. Taste: 10/10 Taste fantastic, very similar to their standard whey. Mixability/Taste: 9/10 Surprisingly it mixes very well. I used a standard shaker cup with blender ball. The only liquid i ever used was water. Effectiveness: 10/10 This all depends on your diet, if you are counting calories and adding this into your diet puts you over your maintenance then you will gain clean weight. Very good ratio of carbs to protein. Formula 8/10 Great combination of different kinds of proteins, the only downside is the fact that the carbs are simple not complex. Overall: 9/10 This is a great product if you are attempting a clean bulk. If you dont mind the extra fat gain i'd suggest just using there serious mass version.

Strawberry Cream

I recently bought this mass gainer in hopes of gaining weight. The result off the mass gainer put on a couple lean pounds (with eating more in general and doing cardio) in a matter of a week. Although, I would not recommend Strawberry Cream because it tastes so bad with 16oz of milk (it's too thin - has no thickness like other mass gainers).

I bought this product because during a bulking up phase I couldn't reach my caloric intake goal because of the amount of food I had to eat. Using a weight gainer would help me achieve this, and ON has a really good reputation with their products. When it comes to flavor, this thing tastes really good, at least for my taste. I didn't really have any unwanted effects while taking it. and it helped me with my goals. One thing I have to mention, which is why I gave it a 9 and not a 10, is because the bag says 1 serving (a heaping scoop) should be 165 grams, but I actually weighted 165 grams, and that made easily 2 heaping scoops. So, what's really a serving size? 165 grams (2 heaping scoops) or 1 heaping scoop and 82.5 grams? That is my only issue with this product.

If you're patient and looking to gain weight, size, and lean muscle; this is a product for you. The key to this product is to be patient though. Don't expect to take one tub or one bag and gain 15lbs. You also need to have a clean diet during use. I weighed 176lbs when I began taking this product. I started by drinking one shake a day in the morning. Over the span of about 3 months, I gained about 6lbs. I eventually plateaued and started drinking two shakes, one in the morning and one before I worked out. I got up to about 193lbs over the span of about 8 months. I stopped using it and leaned out and was able to maintain a weight of anywhere between 185 to 188lbs after I stopped using this product. I recently had oral surgery and was unable to eat solid food for about 2 1/2 weeks. Over this time, I lost about 6lbs. I purchased this product again to help get extra calories to make up for what I had lost, and a boost to gain some weight back. I have an ectomorph body type with a very high metabolism, and almost have to gorge myself to maintain weight. If you're in a similar situation or looking to just gain a little size, I recommend being patient and giving this product a try. It worked great for me!

Great protein powder when you're looking for some extra clean calories or a quick meal replacement. 60 grams of protein per serving and a great taste to go along with it. It takes a little longer than a regular protein shake to mix in a shaker bottle but that is to be expected and it still mixes well with a few extra shakes. Definitely recommend it.

Great product and clean gains. Mixes easily with shaker and does't give me the ***** like other gainers. Gained 10 lbs in 1 bag. You can't go wrong with optimum nutrition.
