Optimum Nutrition Serious Mass

Caloric monster 

Essentially a nutritional supplement to aid one's usual food intake, being one of the most intense weight gain formulas available packing a massive 1,250 calories per serving, which is more than most other weight gainers out there. If you are an ectomorph or generally just want to gain weight this is definitely something that can help you with that. One serving of Optimum Nutrition's Serious Mass has 50 grams of protein blend, 250 grams carbs, 5 grams of fat, 24 vitamins & minerals, creatine and glutamine! When you make a shake of this in milk you're getting a landslide of around 1,500 calories! To put that into perspective that could be equal to about 2. separate meals.

Protein types & sources

The protein formula is a mix of whey protein concentrate, calcium caseinate, sweet dairy whey and egg albumen. All this is to add muscle and also help muscle recovery for people who are doing regular workouts. Recovery is essential because if you aren't careful about that you could cause long-term damage to your body.

Ingestion design & carbs

The mix is designed for a relatively slow release so your body is breaking away bits for a longer period during the day while feeding on it. Serious Mass derives carbs from maltodextrin, some people do say they would have preferred a better source for this, and a small portion comes from sugar.

Flavours & general

Optimum Nutrition's Serious Mass is designed to cover a wide nutritional profile to aid gains and supplement the body to be able to use all that to improve health. Available in banana, chocolate, cookies & cream, vanilla, chocolate peanut butter and strawberry flavour so you can pick which one you find more palatable. Also, just to be careful it is better to try a bit before ingesting larger quantities in case of any allergic reaction or so.
