Optimum Nutrition Serious Mass Review

Optimum Nutrition Serious Mass is a weight gainer designed to help the user intake a serious amount of calories.  The product is designed to target people who have high metabolisms coupled with an active lifestyle and small appetite.  Each serving is packed with 1,250 calories containing 50 grams of protein and over 250 grams of carbohydrates.   Beyond the calories, Optimum Serious Mass has 25 minerals and vitamins with added protein, glutamine, and creatine into each serving.   The protein complex contains fast digesting whey protein and slower digesting casein and egg protein.  This weight gainer also contains no added sugar in the carbohydrate complex.

Compared to other weight gainers, this product is much  cheaper.  Many users report that the taste of this product is better than other weight gainers as well.  A couple of people have also reported being able to overcome strength and bodyweight plateaus.  A common trend in this product is that the users tend to gain weight while on the product.  One such report suggested that hte user went from 140.1lb to 147.8lbs in a matter of 19 days. Since the product contains a lot of carbs, glycogen reserves tend to recover more quickly and the user can get back in the gym quicker.  Furthermore, workouts tend to be more energized and enduring.


The product requires consumers to use 2 scoops per serving. As a consequence, there have been reports of having chunks in the shake.  Shaker bottles can help fix this problem, but small chunks can still be noticed.  Users also report being bloated after the product.  Some complain about the taste, but mixing with mix seems to make the product more appealing.  One can also add banana and peanut butter to the blend.  Another common issue with this product is problems and laxative issues.  This can probably be countered by increasing fiber intake.  Some also become tired, ironically, after consuming the product due to the amount of calories.  The produce also only comes with 6 servings per container which can be disappointing.

Is Optimum Nutrition Serious Mass Worth It?

This product may not be for everyone.  Those who could benefit the most are probably ectomorphs who have a fast metabolism.  For those who are looking to supplement their diet and put on the most quality weights, and also do not belong in the ectomorph category, I would suggest taking only one scoop instead of two.  Combined with milk, this shake will still be a good weight gainer and is going to be less likely to add unwanted weight.  Also those who are sensitive to carbs should probably find an alternative weight gainer to use.  I would also suggest making sure that the shake complements the daily macro-nutrient ratios and daily caloric intake that are aligned with the goals of the user.  I also would advice against using this product if the goal is to lose weight.  As a final note, remember that supplements should not replace real meals as no product will deliver the nutrient needs that mother nature can.

    It should not have a problem being approved as the ingredients are found naturally occurring in the foods we eat everyday.
