When you’re trying to put on size and muscle, you need more than just a good workout plan — you need serious calories, serious protein, and serious nutrition.
That’s why I decided to try Optimum Nutrition’s Serious Mass Protein Powder.
It’s packed with calories, protein, carbs, and nutrients, making it a strong choice for anyone struggling to gain weight.
After weeks of use, I’m ready to share my full experience — including the good, the bad, and everything in between.
My personal experience with Serious Mass
I’ve tried my fair share of weight gainers over the years, and many of them either tasted awful, made my stomach churn, or didn’t really help me hit my calorie goals.
Serious Mass was different right from the start.
I first bought it because I was losing weight faster than I wanted to during a busy season at work.
My job is physically demanding, and I just couldn’t eat enough solid food to make up the calories I was burning.
That’s when I realized a calorie-dense shake could be the answer.
The first time I made a shake, I followed the instructions for a full two-scoop serving.
That was… a lot.
Over 1,200 calories in a single drink felt like a big commitment, especially with the thickness of the mix.
I quickly learned to start with just one scoop until my body got used to it.
This was key in avoiding the overly full feeling some people complain about with mass gainers.
In terms of taste, I was pleasantly surprised.
I’ve had weight gain powders that were chalky and had to be chugged just to get them down.
Serious Mass mixed well in a blender, especially with milk, and adding frozen fruit or peanut butter took it to another level.
My go-to blend became chocolate Serious Mass, a banana, a scoop of peanut butter, and a handful of ice — it felt more like dessert than a supplement.
After about three weeks, I noticed I was holding on to more muscle and even putting on some extra size in my arms and chest.
I wasn’t just gaining fat — the protein content (50 grams per serving) combined with my workouts made sure of that.
I also liked that it has added vitamins and minerals, so it wasn’t just empty calories.
I could feel my energy levels improving, especially during long workdays.
However, I did notice that taking the full serving daily made my grocery bill jump — not because of the powder itself, but because I was adding in so many extras like milk, fruit, and peanut butter.
It’s worth it for the results, but it’s something to keep in mind if you’re budgeting.
Overall, my experience with Serious Mass has been mostly positive.
It’s effective, tastes great with a little customization, and helps you hit calorie goals without force-feeding yourself all day.
Maintenance tips for best results
Start small: If you’re new to mass gainers, begin with half a serving to see how your body reacts before moving up to the full dose.
- Blend, don’t shake: While it can be mixed in a shaker, a blender ensures smoother consistency and better taste, especially with add-ins.
- Use quality add-ins: Frozen berries, bananas, oats, and peanut butter not only enhance the flavor but also boost the nutritional value.
- Timing matters: Take Serious Mass after workouts to help replenish glycogen and kickstart muscle repair, or between meals to keep calorie intake high.
- Stay consistent: Like any supplement, results come from regular use alongside a proper workout plan and adequate rest.
- Stay hydrated: Higher protein and carb intake means you should also increase water consumption to support digestion and overall health.
- Monitor progress: Keep track of your weight, body measurements, and strength gains to see how well it’s working for you.
- Pair with real food: Don’t rely solely on shakes; continue eating balanced meals to ensure you’re getting a variety of nutrients.
- Store properly: Keep the container sealed in a cool, dry place to preserve freshness.
- Listen to your body: If you feel bloated or sluggish, adjust serving sizes and timing to suit your needs.
Pros and cons of Serious Mass Protein Powder
Pros:
- High-calorie content: Serious Mass packs more than 1,200 calories per 2-scoop serving, making it an easy way to hit calorie surplus goals for muscle gain or weight maintenance.
- Quality protein blend: With 50 grams of blended protein, it provides a mix of fast and slow-digesting proteins to support muscle repair and growth over several hours.

- Versatility: You can easily adjust the serving size or add calorie-dense foods to customize it to your needs.
- Trusted brand: Optimum Nutrition is a well-respected name in the supplement world with consistent quality.
Cons:
- Large serving size: Two scoops can feel like a lot to consume, especially for beginners, and it can be heavy on the stomach.
- Sugar content: The carbohydrate profile includes a significant amount of sugar, which may not suit everyone’s dietary preferences.
- Cost over time: While the tub itself is reasonably priced, adding extras like milk, fruit, or nut butters can increase costs.
- Not ideal for cutting: This is strictly a bulking product and isn’t suitable if your goal is fat loss.
- Potential digestive issues: For some people, the high-calorie, high-carb content may cause bloating or gas until the body adjusts.

Serious Mass Protein Powder Vs. other brands
- Serious Mass Protein Powder Vs. Muscle Milk Gainer
Muscle Milk Gainer offers fewer calories per serving, making it better suited for moderate bulking or maintenance phases.
Serious Mass, with its higher calorie and protein count, is more aggressive in helping hard gainers reach surplus goals.
In my experience, Muscle Milk’s taste is smoother right out of the shaker, but Serious Mass gives better long-term size gains due to the larger macronutrient load.
If you need to pack on weight quickly, Serious Mass pulls ahead.
- Serious Mass Protein Powder Vs. BSN True Mass
BSN True Mass has a richer, creamier flavor profile and slightly lower calories than Serious Mass.
It focuses more on balanced macros rather than pure calorie density.
I found that Serious Mass works faster for noticeable mass gain, while BSN True Mass feels lighter on the stomach and might be a better daily option for those sensitive to heavy shakes.
- Serious Mass Protein Powder Vs. Dymatize Super Mass Gainer
Dymatize Super Mass Gainer has a similar calorie and protein profile to Serious Mass but offers more flavor options.
The difference I noticed is in mixability — Serious Mass blends smoother, especially in milk.
Dymatize feels a bit grainier but still effective.
Price-wise, they’re close, but Serious Mass edges out in digestibility and versatility.
- Serious Mass Protein Powder Vs. Naked Mass
Naked Mass stands out for its clean ingredient list — no artificial flavors or sweeteners.
It’s ideal for those who want fewer additives, but the taste can be bland unless you customize it heavily.
Serious Mass offers more flavor and built-in nutrients, while Naked Mass gives you more control over what you add in.
For convenience and taste, I’d still lean toward Serious Mass.
- Serious Mass Protein Powder Vs. Rivalus Clean Gainer
Rivalus Clean Gainer is lower in calories but higher in quality carbs and fats from whole food sources.
It’s a cleaner choice for those avoiding excess sugars, but it won’t push weight gain as fast as Serious Mass.
I think Rivalus is better for lean bulking phases, whereas Serious Mass is more effective for anyone struggling to eat enough food to grow.

Frequently asked questions (FAQs)
There’s no single “best” medicine for neuropathy, as it depends on the underlying cause. Prescription options may include medications like pregabalin or duloxetine, while some people find relief from supplements or lifestyle changes.
Supplements like alpha-lipoic acid, B vitamins, and acetyl-L-carnitine have been studied for nerve health. While they may support repair, complete reversal of damage depends on the cause and severity.
Many treatments can help manage symptoms — from medications to supplements, physical therapy, and dietary changes. Effectiveness varies from person to person.
Some neuropathy gummies contain ingredients that may support nerve function, but their effectiveness depends on the formulation and dosage. They can be a convenient option, but results may not be as strong as higher-dose capsules or powders.
Final Thoughts
Serious Mass Protein Powder does what it promises — delivers high calories, big protein, and a nutrient boost to help you gain size.
It’s not perfect, and it’s not for everyone, but for hard gainers or anyone struggling to hit calorie goals, it’s a reliable tool in the muscle-building toolbox.
Just start slow, blend it well, and pair it with consistent training for the best results.
