Review: Highly recommend for anyone looking to bulk up effectively! 💪 - This is my 5th time buying Optimum Nutrition Serious Mass, and it continues to deliver great results. It has really helped me maintain a steady calorie surplus and support my weight gain goals. The taste is consistent, it blends well (especially in a smoothie), and I like that it includes added vitamins like Vitamin C and Zinc. I’ve seen noticeable improvements in my weight and muscle size when using it consistently with workouts.
Review: It helps a lot - Optimum Nutrition Serious Mass is a great choice for anyone looking to gain weight, build muscle, or increase overall calorie intake. The Chocolate flavor mixes smoothly—especially if you use a blender—and has a rich, dessert-like taste without being overly sweet. Each serving delivers a very high amount of calories, protein, and carbs, which makes it ideal for people with fast metabolisms or those who struggle to eat enough throughout the day. It also includes added vitamins, minerals, and creatine for extra support. The bag is large and lasts a good amount of time depending on how much you use. The powder is heavy, so mixing by hand can be a bit difficult, but blending solves that problem easily. Overall, Serious Mass is effective for healthy weight gain and muscle-building goals. If you need a calorie boost and don’t mind a thick shake, it’s a solid and reliable product.

## Questions & Answers

**Q: How well does this work? I'm a teen with a high matabalizum and I'm looking to build mass and bulk up**
A: I’m nearly 50 years old, but seeing this question I had to comment.  Until I was around 32 or so, I couldn’t gain weight no matter how much I had to eat; or so it seemed.

I remember not caring whether it was fat or ideally muscle, I just didn’t want to be skinny anymore.

Then I hit a point in my life where the metabolism slowed and I couldn’t keep the weight off.  That lasted for nearly 15 years and for some reason my appetite suddenly plummeted and now I’m back looking at weight gainers simply to do nothing more than maintain a healthy weight.

Just try to keep in mind that human physiology typically prohibits putting on large amounts of muscle in a short period of time naturally.  That means that a large portion of quick gains will be fat.  Embrace your high metabolism and shoot for a reasonable goal.

That said, the more calories you intake in a day that exceeds what your body can burn, the quicker you will gain weight.  For the most part, it’s simple math.  Total Intake - Total Burned = Energy Stored Primarily as Fat.  There are about 3500 calories in one pound.  If you were to forge an extra 3500 calories a day, you could theoretically gain 7 pounds a week.  For someone like you, that probably means eating 8,000 calories a day.

Now as far as this product goes, it’s one of the highest calorie per serving gainers I have seen and it’s much quicker to pound a shake than to eat a steak!

Another thing to keep in mind is that supplements that are fortified with vitamins and minerals, have the potential to far exceed recommended safe values for human consumption.  I ran into this when I was your age.  I was drinking over a gallon of milk a day, milk is fortified with vitamin D and that build up led to some freaky painful headaches in me personally.

Too much calcium can also upset your bodies homeostasis and lead to surprising problems.

Being young, your body can handle a lot!  Just wanted you to be aware of the things I wish I knew when I was your age.

If I were young again I would focus on speed, agility and good clean ripped muscle!  Shredded muscle always looks bigger than fat muscle.

Cheers!

**Q: banana**
A: I’m adding my two cents.

Chocolate peanut butter is the truth. Banana was good at first, and then it wasn’t.

**Q: Does it work without work out ?because im so busy all day**
A: First off, I am so sorry that everyone that responded to this question this far hasn't answered your question. I'm seeing you ask if this helps you put on weight without working out. I've seen 3 or 4 people put "no excuses, no short cuts," "no motivation, no nothing" and other meat head answers. I apologize about them =)

Getting to your question. Yes, it does help you gain weight even if you're not working out. I understand you're busy...who's not? Working out and drinking this is without question the best way to gain weight. But, for the last 2 weeks I've been drinking a scoop in the morning, and a scoop at night before bed. And I've gained 3 pounds! Doesn't sound like a lot, but if I don't get 6 eggs every morning, I'll loose 2 pounds. If I don't eat 400 calories everyday, I'll loose 2 pounds. I have such a low fat to muscle ratio that if I type it in, people won't believe me, so ill save it for the haters on YouTube (jk) 😅 

But yeah, this stuff works. Might jist be a pounds a week, but if you're like me, that's great success. This does work without working out as long as you drink it consistently. Best of luck to you my friend.

**Q: will a high intensity sport like basketball plus weight training, 5 days a week  lessen the effectiveness of this product??**
A: The guy who says this causes cancer is lying or is just ignirant. Some other supplements may but even at that mant studies don't say which ones. Powder prorein supplements do not. As do many men, i don't use this product for muscle gain. I use max muscle for that. I use this for belly fat gaining.

### ⭐⭐⭐⭐⭐ Great Weight Gainer, Quality Product.
*by A***A on October 27, 2025*

I purchased this item for my father, as he was looking to gain weight. We've used this brand before, and he's liked the taste, as well as the overall feel of it, so we decided to give it a shot. This powder is easy to use and incorporate into a daily diet. It's also packed with vitamins and protein, which is a nice bonus. The quality is also excellent. It dissolved easily in a shake, and also digests well. The texture is a little rough, though balanced and not too chunky when thoroughly incorporated, and overall, it is great. At $50 for 6 pounds, it's a bit pricey, but quality doesn't come cheap. I would recommend this product.
