Gainer
The price is right. Taste is pleasant. Sort of thick with the recommended amount of water. 1 serving has me feeling completely full and I can eat a lot. I found I had to use a mixer for a smooth consistency, I wasn’t able to get it to mix well in the shaker bottle.

Effective Weight Gainer with a Few Reservations
Optimum Nutrition Serious Mass Weight Gainer has been an integral part of my journey to gain weight and build muscle. With its high protein and calorie content, it's undeniably effective in helping achieve those goals. While I'm quite satisfied with the results, there are a few aspects that give me pause. 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.

It does what it's intended to do.
Alright, when I read the other reviews for this product I invariably end up infuriated. This is a great product that provides 1500 calories at a relatively inexpensive price. This product will help you gain weight significantly faster than most other brands in the same price range. So everyone needs to stop complaining about the taste! Its not made to taste good its made to add some muscle to all you ectomorphs out there that can't gain weight to save their lives. That being said, I have tried every flavor and will provide a brief description of their tastes. Flavors: Chocolate: Second best of all the flavors that are available. It is appealing because its harder to get sick of chocolate then some of the other flavors they offer. Banana: By far the best flavor for this drink. Banana successfully tastes like a pretty good milkshake when mixed with milk but doesn't taste very good when mixed with water. Vanilla: An okay flavor, not as good as banana or chocolate but decent none the less. Strawberry: Avoid strawberry! It tastes horrible and for some unknown reason, it had a different and unappealing consistency compared to the other 3 flavors. So my recommendation is to alternate between banana and chocolate or to buy banana serious mass and add in some Optimum Nutrition protein powder which makes it taste even better. Again, I have gained 15 pounds using this stuff over the course of 2 months and my best friend has gained about 20 pounds in the same amount of time. It really does work if you take it every day. I generally take one heaping scoop in the morning with breakfast and one before I go to sleep.

Not the best, but it is the cheapest.
Cheapest for the amount given, so if you are trying to budget it's the way to go. I have tried 7 weight gain brands now and 9 flavors. It was a little hard to choke this one down, but possible for a half serving. I had to get the Vanilla and put in Strawberry syrup for the best taste I could gain and added calories. I would recommend Serious Mass if you buy a lot of weight gainers and are trying to budget as I am, and if you can stomach the taste (better than most others I tried). I have been spending too much to maintain an optimal weight (super high metabolic rate) so I needed to get the big bulk bag. With Orange Juice, the taste was cut a little and chocolate syrup was okay. Overall, I would recommend this of any if you can stomach it and need as much for the little cost as you can. I actually gained the most weight on BSN True Mass though, because I consumed it faster than anything else I tried due to having actually liked it. That was one I didn't mind drinking the shake at the end of a workout. I got the Cookies and cream vanilla one and put in Strawberry syrup for a couple hundred extra calories. I found I often skipped drinks with Serious Mass and other protein shakes due to lack of taste and desire to drink it. Sure weight gain for a lot is about "who cares on taste - bulk up now! Become hulk!". For me, it's about cost (I'm not rich here), and the desire to WANT to drink this not only at the end of a workout, but think of it as a treat before going to sleep as well. Hey, I'd rather reward myself than put myself down after I workout. Who wants a slap in the face after they worked hard and strained their body? I'd prefer the path of reward. So I'm like a puppy, I'm okay with that. In short, if you can spend a bit more, BSN True Mass... if not and can choke down an above par protein shake and need a lot of it, Serious Mass. Also, with Serious mass I noticed it had creatine listed as an ingredient on the bag. Drink plenty of Water in your workout - very important - to get best results. That water is soaked up like a sponge by the creatine. With any Creatine, if you are not drinking enough fluids, you are going to feel bad at the about a half an hour after that drink. Very important to get those fluids in you.
