Why True-Mass?

True-Mass® is an ultra-premium lean mass gainer, designed to promote muscle growth. It features BSN®’s signature ultra-premium protein formula to feed an athlete’s muscles with essential protein building blocks. The unique carbohydrate blend provides the caloric support necessitated by extreme physical exertion, helping the body prepare for and support recovery from intense training. Healthy fats supply quick-burning fuel to satisfy the serious athlete’s energy demands. And all these high-quality ingredients come delivered with BSN®’s exclusive flavor technology, producing one of the most mouth-watering mass-gaining shakes on the market.*

True-Mass®’s balanced composition makes it a nutritious source of caloric support and useful as a healthy meal replacement as part of a balanced diet plan. Its ultra-premium blend of protein, carbohydrates and healthy fats promotes increases in lean muscle mass.* And with a taste that can’t be matched, when it comes to mass gainers, True-Mass® is in a class by itself.*

BSN True-Mass Ingredient Profile

BSN True-Mass® Proprietary Protein Matrix:

  1. Hydrolyzed Whey Protein ( 1/2 - 1 hour digestion rate)
  2. Ultra-Filtered Whey Protein Concentrate (2-3 hour digestion rate)
  3. Microfiltered Whey Protein Isolate (2-3 hour digestion rate)
  4. Egg Albumen (2-3 hour digestion rate)
  5. Milk Protein Concentrate (4-6 hour digestion rate)
  6. Calcium Caseinate (6-8 hour digestion rate)
  7. Micellar Alpha and Beta-Caseins and Caseinates (6-8 hour digestion rate)

Each of True-Mass®'s proteins offer an exclusive and complimentary profile of amino acids and absorption rates, guaranteeing that your muscles never run out of protein building blocks.*

Sustained-Release Multi-Functional Micellar Protein Matrix: Contains fast and slow digesting proteins, which supports/elevates circulating amino acid nitrogen levels for up to 7 hours. Suitable for A.M. or P.M. use.*

Glycogen Uptake Matrix: Original blend of carbohydrates that is appropriate for A.M. to P.M. use; helps with recovery and energy for exercise.*

Glutamine Alpha-Ketoglutarate (AKG) and Glutamine Peptides: Glutamine AKG and glutamine peptides serve as efficient and stable forms of glutamine for maintaining whole-body glutamine supplies.*

Bioactive Protein Utilization Enzymes (Aminogen® and Papain): Encourages optimum protein digestion and absorption, which improves uptake of amino acids by the muscle.*

Fiber Matrix: Fiber supports gastrointestinal health, enlarging the surface area that the body can absorb nutrients across, which increases nutrient uptake and utilization.*

MCTs (Medium Chain Triglycerides), and EFAs (Essential Fatty Acids): MCTs are a fast-burning energy source, much like a carbohydrate. They encourage the oxidation of fat over carbohydrate and assist in regulating appetite. EFAs (essential fatty acids) are not created by the body and must be consumed in order to prevent deficiency.*

Branched-Chain Amino Acids (BCAAs) and Essential and Non-Essential Amino Acids:Contains more than enough amounts of every amino acid required in the human diet.*

BSN's Exclusive Advanced Flavor Technology: A breakthrough in flavor technology that mimics some of the most mouthwatering shakes you have ever tasted.

I love the taste. I gained 3kg without having problem with my waist. At first I thought I can’t take it because I suffer stomach ache and diarrhea. After the 5th day I’m used to it. Lucky me. No more stomach ache or diarrhea. The multi phase protein releases make me easy for me to keep my body in positive nitrogen balance state. Low calories mass gainer. Good for those who into clean bulk.


Used this gainer about 3 weeks already (Chocolate flavour). This is the tastiest mass gainer i ever tried. Stack it with creatine and glutamine with great result and no bloating. The only downside is the high fat content. Would like to try cytogainer after this.


My very first bottle of protein powder and i must say the results are satisfying. This is a wonderful product for ectomorphs like me who wish to gain muscle and mass. I've gained approximately 2kg in mass and I could see a little more definition from my muscles. Basically, it's a good product with great taste but due to it's low amount of servings, it's quite costly for long term users of this product.


This is my first weight gainer.It has high quality protein.I've gained nearly 3kg for 1 tub,I don't know about other people but that's consider a great gain for me.After drinking a serving,my body feel warm and a little bit tiring,you have to drink more water from keeping your body dehydrating.I choose chocolate flavor and it really does taste like real chocolate shake.It is also quite easy to mix,just use a shaker bottle and shake for about 20 seconds(that's how I shake it),and drink it.No clump at all.
