Ultra-Premium Protein/Carbohydrate Matrix

TRUE-MASS® is an ultra-premium lean mass gainer, designed to support muscle growth and muscle recovery for athletes with above normal caloric needs.* The formula behind TRUE-MASS® features a 2-to-1 ratio of workout-fueling carbohydrates to muscle building protein, with 90 grams of carbs per serving and 50 grams of protein at 700 calories. Plus, we included 6 grams of dietary fiber per serving and Medium Chain Triglycerides to round out the nutritional value of each shake and complement BSN®’s legendary great taste. Used post-workout, between meals and/or before bed, TRUE-MASS® can fuel your recovery from heavy training while providing the nutrients your body needs to keep on building.

Gain with the Best of Them!

TRUE-MASS® features BSN®’s signature ultra-premium protein formula to feed an athlete’s muscles with the 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.


BSN®’s protein powders, such as Syntha-6® and Syntha-6® Isolate, are comprised primarily of protein and contain only small amounts of fats and carbohydrates, while staying under approximately 200 calories per serving. These protein powders are recommended to supplement protein intake through-out the day and as a post workout recovery shake. While TRUE-MASS® is a perfectly good option for these applications as well, its strength lies in its formula of a 2-to-1 ratio of carbohydrates to protein, which is geared towards athletes who require an above normal caloric intake or who have a hard time meeting their caloric intake in a given day.

BSN Supplementation

At BSN®, we have designed our products to complement one another. When used together, they can help enhance the overall benefits of your supplementation and workout regimen.

Great product, in the little time I have been taking this BSN item I can already see some mayor results. The taste of the Chocolate flavor its putty good and refreshing compared to other products that taste like medicine, not this item. Definitely recommend it!

I have tried a few mass gainers and this is by far the best. The flavor is fantastic and you can really tell the difference in the quality of the ingredients just from the taste. It mixes very well. Full serving (3 sccops) into a 28 oz blender bottle with blender ball and I have no chunks. Just a silky smooth 700 calorie meal. It is a little pricey compared to other products but if you are ok with paying more to enjoy it and make things that much easier to stay on track then I highly recommend True Mass.

I’ve been consuming this particular protein for some years now and have been since. No need for another, the results are spectacular. As far as taste, there is no competition. Vanilla mixes well with anything, I personally mix it with an orange Gatorade to create the “creamsicle” shake. Keep up the outstanding work BSN.

I used this gainer for nearly a month straight and gained close to 2 pounds. This is pretty good for me as I'm a hard gainer. The flavor was amazing and it mixed easily. Probably the easiest mixing and best tasting mass gainer I've had to date. Only con I have is that I wish this product had little less sugar and some cleaner ingredients. Other than that it's a good product.

By far the best gainer I have ever tried. Flavor and quality wise, I believe true mass is at the top of the gainer category. It has helped me so much with my bulking and has made gaining weight and consuming enough calories effortless. I have tried other gainers and believe me, true mass is on another level with its taste. Highly recommend for any lifter looking to bulk up

I recently started my journey into bodybuilding (I've been training for about 2 months) and although I've gained some strength, I haven't really put on any weight. I thought I'd give supplements a shot as I'm 6ft 1, weighing a mere 148 pounds (67kg), I originally ordered Mutant Mass (Vanillia Icecream) and I just couldn't stomach the taste so I decided to purchase BSN True-Mass, let me tell you, the chocolate milkshake flavour actually tastes better than an actual milkshake. If taste is a big factor for you when it comes to powders, I'd definitely recommend this, however, as far as weight gain is concerned, I've only just had it delivered so I cannot give my honest opinion on that. 10/10
