BSN is highly regarded when it comes to creating great-tasting protein shakes. I wanted to find out if their weight gain powders also featured a good balance of nutrients and mouth-watering flavors. In this review, I evaluate BSN True Mass based on these areas:

  • Nutritional value
  • Protein composition
  • Flavor  
  • Pricing

Once you are done reading the entire review, you will be in a better position to decide whether BSN True Mass is the perfect weight gain supplement to add to your bulking diet.

Before we start, I want to present just the basic facts about BSN True Mass.

BSN True Mass seems to cater to casual gainers who do not need gigantic amounts of calories in their mass gain shake. It utilizes a 2:1 carb-to-protein ratio to support weight gain, giving you a decent 700 calories in each serving.

700 calories may not sound like much, especially when compared to weight gain shakes that are formulated for hard gainers – some of which contain up to 2000 calories per serving. 700 calories are still roughly the same amount of calories you get by eating 2 double-patty hamburgers!

If you are aiming to gain lean weight and achieve a well-rounded physique, 700 calories can go a long way – especially if paired with the right diet and exercise.

Being skinny, I’ve spent hours poring over the internet, looking for a high protein weight gain shake. I just want to make sure that my muscles are nourished with generous amounts of amino acids to trigger muscle growth and repair.

BSN True Mass weight gainer excels in this area by bringing together 8 different protein sources – each one with a unique absorption rate. This keeps my muscles nourished with nutrition and amino acids for longer periods.

One serving of True Mass weight gainer is packed with 46 grams of protein from 8 sources – all of which supply your body with the 9 Essential Amino Acids and the 3 Branched Chain Amino Acids. For me, 46g of protein looks quite impressive on a weight gain shake.

Who is BSN True Mass Best for?

If you are:

  • Someone who wants high amounts of protein in their mass gainer
  • Someone who is tired of dull-tasting weight gain drinks
  • Someone who is on a budget

Then, continue reading.

However, if you are:

  • Someone who wants massive amounts of calories in their drink
  • Someone looking for creatine in their mass gainer
  • Someone who is lactose-intolerant

I don’t think BSN True Mass is the right weight gain supplement for you.

If you prefer higher amounts of calories in your shake, you might want to take a look at Dymatize Super Mass Gainer or Optimum Nutrition Serious Mass. Both these weight gain supplements contain more than 1000 calories in one serving.

This is What I Think About BSN True Mass…

Nutritional Profile

After glancing over its nutritional label, BSN True Mass looks well-built for supporting the caloric needs of casual gainers.

I’ve seen weight gain shakes that contain as much as 2000 calories per serving – those are typically suited for hard gainers who want to push lean weight gain to the max. True Mass, however, looks to be tailored for casual gainers who just want to build extra muscle mass without turning into a hulking monstrosity.

Each serving of True Mass weight gainer is loaded with a respectable 700 calories. If you want to boost this number, you are more than welcome to mix it with milk – instead of water – or throw in a few scoops of peanut butter, oatmeal, or ice cream.

True Mass boasts of a 2:1 ratio of carb-to-protein ratio for supporting weight gain.

You get 87g of carbohydrates, in the form of maltodextrin. Maltodextrin is rapidly digested and absorbed by the body, which means that it quickly gets to work in delivering nutrients to muscle cells and replenishing lost energy after your workout.

BSN True Mass also got my attention as it comes loaded with Medium Chain Triglycerides. These healthy fats are readily used by your body as a source of energy, so you don’t have to worry about them getting stored as unwanted fat.


My goal is to load my body with rich amounts of calories so that I can build mass in less time. With only 700 calories per serving, True Mass looks like a decent choice for casual gainers. But personally, I would rather have a weight gain shake that gives me more than just 700 calories in each drink.

Protein Content

I think True Mass weight gainer truly shines when it comes to its protein content. While it doesn’t really deliver the most protein per serving (46 grams per serving) when compared to other mass gain drinks, it packs in 8 different protein sources in its formula.

I checked the list of protein sources included in its Protein Matrix, and I saw these:

  • Whey protein concentrate
  • Milk protein isolate
  • Whey protein isolate
  • Hydrolyzed whey protein
  • Calcium caseinate
  • Micellar casein
  • Egg whites
  • Wheat glutamine peptides

With this protein blend, you get slow-, medium-, and fast-digesting protein sources all at the same time. This lets you enjoy the quick and sustained delivery of muscle-building aminos to your body for extended periods.

Given its well-balanced protein blend, True Mass weight gainer may be consumed virtually any time of the day. Whether you drink it in the morning, in-between meals, after exercising, or before sleeping at night, True Mass can keep your muscles nourished for long periods.


I drink a mass gainer to build lean muscle, so I try to choose those that have a high protein content. For me, BSN True Mass weight gainer cuts as it gives me 46 grams of protein in one drink. That’s even more than what you see on some protein powder supplements!


To be honest, I am quite hard to please when it comes to the taste of a weight gain shake. Having tried a few other mass gainers in the past, I’ve had my fair share of chalky-tasting drinks or simply unappealing shakes.

BSN True Mass prides itself in dishing out milkshake-tasting protein supplements – and that’s what I also experienced with this weight gainer.

When mixed with plain water, True Mass has a smooth and clean flavor that agrees well with my palate. But when you mix it with milk, I just got surprised with how rich and creamy it tasted- something that reminds me of my favorite milkshake back when I was still a child.

True Mass is offered in Chocolate Milkshake, Strawberry Milkshake, Cookies, and Cream, and Vanilla Ice Cream flavors – all of which sound just like gourmet dessert choices, right?


I love how True Mass mixes perfectly with milk – you get that milkshake taste and consistency that will keep your taste buds excited. This weight gain shake will definitely make it to my list of great-tasting mass gainers.


As of this writing, BSN True Mass is priced at $48.46 for its 5.82lb tub. According to its label, each tub is good for about 16 servings – giving us a final cost of approximately $2.90 per serving. That sounds good, especially for those who are looking to make the most out of their hard-earned money.

At $2.90 per serving, BSN True Mass may help you build muscle without you spending a fortune – that is, if you are happy getting only 700 calories per serving.


If you are not willing to spend huge amounts of money on a weight gainer shake, BSN True Mass can be a good choice. At $2.90 per serving, you get good amounts of protein and a gourmet-tasting drink at the same time.

Check Out My Results from Using BSN True Mass

To make this weight gain shake work for me, I decided to mix it with milk, and not just plain water. Doing so lets me hit 2 birds in 1 stone: I boost the calorie and protein content of my shake, plus I get to treat my taste buds to a rich and creamy drink.

After using this weight gain shake for a few weeks, I can say that I’ve noticed decent muscle gains and packed on a few extra pounds. Just make sure to take this weight gainer with a good training program and a wise choice of food.

Here are some Amazon reviews that I ran into while checking out BSN True Mass:

“I’ve been weightlifting for over 30 yrs and can honestly say this product is the best I’ve ever used. Not only does it taste good, mix easily, and doesn’t give me stomach issues, it has given me a noticeable boost in strength and size, even at 57yrs old.”

“My husband has struggled with gaining weight his entire life. We had a friend recommend this brand for us and will never go back. Most protein weight gainer shakes taste “gritty” or “chalky”, but this brand HE LOVES. We have so far purchased 3 bags, he goes through, on average, 1 bag per month and since has GAINED 20 LBS!!!

He especially likes the shakes blended with ice cream.”

“Love the flavor almost too much. I had to cut back to one shake a day, as I was packing in too many calories for my needs, but it was hard to do because I look forward to this gainer more than any other I’ve tried. Guess that should motivate me to burn more calories in the gym!

Consistency in a shaker bottle is smooth, and as long as you shake vigorously as soon as the water hits it, it’s clump-free. I usually add a few ice cubes, as I like my shakes cold.”

Is BSN True Mass the Right One for You?

After going through its pros and cons, taking a look at all its offerings, and giving you my personal experience after taking it, it’s YOUR turn to decide if BSN True Mass will meet your mass-building needs.

For Casual Gainers

700 calories look just about right if your goal is to build decent muscle mass – and not turn yourself into a freak of nature. Giving you 46g of protein, 87g of carbs, and 18g of fat per serving, BSN True Mass can be a good supplement for casual gainers.

For Protein Heads

If you are just like me, who loves checking the protein content of a mass gain shake, then BSN True Mass won’t disappoint. One serving gives you 46 grams of protein, which features 8 protein sources with slow, medium, and fast absorption rates.

You get to enjoy the muscle-building benefits of whey protein concentrate, whey protein isolate, hydrolyzed whey protein, milk protein isolate, calcium caseinate, micellar casein, egg whites, and wheat glutamine peptides in this mass gain supplement.

For Milkshake Aficionados

The last thing you want is a mass gain drink that makes you wince and gag with each sip. BSN True Mass is likely to impress your palate with its creamy taste and milkshake-like texture. Mix it with milk and throw in some fruits for an even more satisfying experience.


For skinny people or hard gainers who are looking to get more calories from their mass gainer, Optimum Nutrition Serious Mass is a good alternative to consider. Each serving gives you a robust 1250 calories, 50g of protein, and 254g of carbohydrates – perfect for those who are looking to experience serious weight gain.

Optimum Nutrition Serious Mass Weight Gainer

The Bottom Line

To end things, I would say that BSN True Mass is a good choice for those who just want basic mass-building nutrition. Sure, you don’t get the highest amounts of calories per serving, but this weight gain supplement is no pushover when it comes to its protein content.

It features 8 complete protein sources, so you know that your muscles are getting the nutrition they need for growth and development. Its carb content (87g per serving) is quite low when compared to leading weight gain shakes, so you may want to boost your carbohydrate intake to compensate.

With 700 calories per serving, I recommend mixing it with milk and adding some scoops of ice cream or peanut butter for a quick calorie boost.

Taste-wise, True Mass is something I won’t easily get tired of drinking. I had no difficulty chugging on this drink and actually felt excited about my next serving at all times.
