1. Taste: Some people said it doesn't taste good. In my experience, most people mix their weight gainers or protein shakes with water. Considering water is pretty much tasteless, you're pretty much drinking chocolate powdered water. Of course that doesn't sound tasty. Personally, I mix it with milk, which makes sense considering I want to consume as many calories as I can each day. Of course it doesn't taste like a chocolate milkshake, but taste isn't the highest priority. That being said, Serious Mass actually tastes good to me, and is something I can drink every day (or every other day) without getting sick of it.
2. Price: The BSN True Mass gives you 5.75 pounds for about 35 bucks, whereas I bought the 12 pound bag of Serious Mass for about 44 bucks. I also only use half the serving size each day, so the bag lasts me about a month, and it's still an extra 600 or so calories a day. So 44 bucks for a months supply is pretty good considering most other weight gainers cost at least 20 bucks more for the same size bag.
3. Thickness: Yes, it is a thick shake, but like someone else said, you're consuming a lot of calories in just one shake. It's supposed to be thick. Personally, when I make a shake, I'll put half the serving in the blender, mix it up with about 4 cups of milk (which makes over 1000 calories in just one shake), and drink it throughout the day. It sure beats drinking it all at once and feeling bloated for the next hour or so. I also found that it mixed very easily in a blender, and didn't clump at all.
4. Purpose: Serious Mass, like all other gainers, is a SUPPLEMENT. It's not a miracle shake that will increase your muscle mass just by having a shake or two every day. You need to find out how many calories you need to consume a day in order to gain muscle, and keep track of what you eat. Actual food will always be superior to weight gainers or protein shakes.
In conclusion, Serious Mass is a great product. My suggestion for people is to do what I do, and keep a blender full of Serious Mass and milk, and sip on the shake in between your meals. If you're wondering about whether to get this product, try and find someone who has it, and give it a whirl. Either that or find the cheapest bag you can find of this stuff so you can try it out.
First and foremost, the impact of Serious Mass on my weight gain has been noticeable. The combination of high protein and calorie levels has definitely contributed to my muscle growth and overall mass gain. It's reassuring to have a product that delivers on its promise and aids in achieving the desired results.
However, my enthusiasm is tempered by the ingredient list. While Serious Mass contains the necessary nutrients for muscle building, the sheer number of ingredients listed makes it difficult to discern exactly what I'm consuming. This lack of transparency raises some concerns about potential additives or fillers that may not align with my nutritional preferences.
Taste-wise, Serious Mass is quite palatable, especially considering its nutritional profile. The variety of flavors available allows for some diversity in my shakes, which is a definite plus. Mixing the powder can sometimes be a bit challenging, and clumps can form, but with a little patience and a good blender, this can be managed.
In terms of value, Serious Mass offers a substantial amount of product for its price, which is commendable given its effectiveness as a weight gainer. It's a cost-effective solution for individuals looking to bulk up without breaking the bank.
In conclusion, Optimum Nutrition Serious Mass Weight Gainer deserves a solid four stars from me. It has undeniably helped me achieve my weight gain goals by providing the necessary protein and calories for muscle growth. While I'm somewhat uncertain about the extensive list of ingredients, the overall benefits and results have outweighed my reservations. For those seeking a reliable weight gain supplement, Serious Mass is worth considering – just be prepared to overlook some ambiguity in its ingredient composition.

Como puntos positivos, el cazo de dosis de mayor tamaño facilita que no te quedes corto en las dosis diarias de macros. Se nota enseguida la subida de calorias y nutrientes, llegan rapido las mejorar a nivel de carga diaria de trabajo. Tiene buen sabor y suficiente densidad como para que sepa bien aunque lo mezcles con agua, cosa que otros "Mass Gain" terminan sabiendo aguados.
Como punto negativo, cuesta diluirse y en mezclador deja más grumos que otras marcas, pero tampoco me molesta en exceso.
