Now I have not only taken a few years off, (haha) but have added lean muscle and its really noticeable. Key is get into the gym and be consistent. I will be buying another canister when this one runs out.

Nice big bucket of mass gainer. The taste is great and definitely one of the better tasting chocolates (the flavor I got) in comparison to competitors. Look on the label and it speaks for itself when it comes to the nutrition content in a serving. A large dose of carbohydrates with minimal fats and a good dose of protein. Seems like a pretty well rounded supplement/mass gainer. Id recommend this to someone who doesn’t get enough macros in from just eating and is looking to put on mass. I plan on supplementing this with an additional protein powder that is more pure protein to hit my protein goals. This supplement has the carbs covered. Optimum nutrition is a reputable tried and true brand. Give it a shot if you are looking to put on some mass.
Optimum Nutrition is a very reputable brand in the bodybuilding/sport nutrition space. I have used their products before and know that they are made with quality ingredients designed for building muscle. I prefer to mix this powder with milk, because I like the consistency & taste better than water, but if you are lactose intolerant or don't have milk available, water will do just fine. I used a blender bottle and it mixes well with just shaking. This product is great to drink after a workout to feed your muscles with quality protein to maximize your muscle gain after a workout. This powder can also be used in smoothies or cooking. It is high in calories compared to a normal whey protein, and is meant for building mass, as opposed to a low calorie protein for lean ... MoreOptimum Nutrition is a very reputable brand in the bodybuilding/sport nutrition space.

I've been using Optimum Nutrition Serious Mass (Chocolate) for about 2 months now, and I've been really happy with the results. I'm a hard gainer, and it's been tough for me to put on weight in the past. But with Serious Mass, I've been able to gain about 10 pounds in just a few weeks. I like that Serious Mass is high in calories and protein. Each serving has 1,250 calories and 50 grams of protein, which is great for helping me build muscle. I also like that it has a good mix of other nutrients, like vitamins, minerals, and carbohydrates. The taste of Serious Mass is also good. I've tried the chocolate flavor, and it's not too sweet or too chalky. It mixes easily with milk, and it's not too thick. Overall, I'm really happy with Optimum Nutrition Serious Mass.

This is a high-quality powder that'll help you gain mass in a pretty quick amount of time. I really like the vanilla flavor, it's sweet and not overpowering when I mix it in blender with water/milk. Please understand that this 3-pound container only has 4 servings in each, each serving is big and full of protein but it's definitely a lot and you can't substitute this with normal protein powder. This is specifically for people who are trying to bulk up for whatever reason (or perhaps for people who need it for health reasons, I'm not sure, point is this cannot work as a substitute for pure protein and you WILL gain weight if you take this). I used a blender and despite being a ton of power it mixed pretty well. Each serving includes 50 grams of protein along with ... MoreThis is a high-quality powder that'll help you gain mass in a pretty quick amount of time.

I do think that it's impractical to purchase only 3 pounds of this stuff though, it's unlikely that you'll only take 4 servings, they sell giant bulk bags but even their 6-pound tub would be a better choice in my opinion. Point is, this stuff works as intended, blends relatively easily and tastes great. I have no complaints.
Impressive container of mass gainer goodness! The taste is fantastic and it's hands down one of the best flavors I've tried when compared to competitors. Check out the label and you'll see the nutrition content in each serving speaks for itself. A generous portion of carbs with minimal fats and a solid dose of protein – it's a well-balanced supplement that covers the essentials. I'd definitely recommend this to individuals who struggle to meet their macros solely through food and are aiming to pack on some mass. While I'm planning to supplement this with a purer protein powder to hit my protein goals, this mass gainer has the carbohydrate aspect nicely sorted out. Optimum Nutrition is a reputable brand with a proven track record. Give it a try if you're on the hunt ... MoreImpressive container of mass gainer goodness!
