1200 calorie mass gainer formula

TRUE-MASS® 1200 is the Ultimate Mass Gainer engineered for the true hard-gainer in need of serious caloric support. TRUE-MASS® 1200 features a 4:1 ratio of carbohydrates to protein, with 215 grams of a unique complex carbohydrate blend that includes ground whole oats and 50 grams of BSN®’s signature protein formula along . Plus, the formula includes 12 grams of naturally occurring BCAAs and 25 grams of EAAs per serving along with added dietary fiber and Medium Chain Triglycerides to round out the nutritional value of each shake. Used post-workout, between meals and/or before bed, TRUE-MASS® 1200 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® 1200 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 regular protein intake through-out the day and as a post workout recovery shake. While TRUE-MASS® 1200 is used for these applications as well, due to its high protein, carbohydrate and calorie count, this Ultimate Mass Gainer 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.

Definitely one of my favorites in flavor and mixing quality...but honestly...I can't say that I made any noticeable gains from BSN gainers. I've been off and on for a period of 2 years always hoping to see results, but mainly drink for the flavor. Might just be me.

This is the only Protein shake I am loving so far. I have been trying Super Mass gainer, PRO gainer I did not see any results but after trying True Mass I felt differences and I am about to reorder two more bags

Great taste and mixes well. I’ve been using protein shakes for over 20 years and I feel that BSN has the best quality. I wouldn’t think of changing brands and have even convinced a few gym friends to use this product.

Best mass gainer considering taste, value and effectiveness. To those whiners complaining of the texture being thick and grainy, what did u expect? Its a mass gainer not a protein shake. Tip for those using only blender bottle, pour the milk first, not the powder. P.S. I have tried UN real gains, ON serious mass and pro gainer, mutant mass and bpi bulk muscle. Real gains was a bit more effective than true mass but it tasted horrible but drinkable and its so expensive. Pro gainer (strawberry) tasted horrible as well so i threw the whole tub away. The rest just cant compared to true mass.

Great result. My weight never passed 73KG till the time I used this product. You definitely need to use a mixer to mix it with milk or whatever you want. Taste is great. It keeps you going till the next meal. I just loved it !

Charismatic!! I have not seen such a tasteful protein ever in my life. Long live BSN!! Excellent results!! I strongly recommend everyone to switch to this mass gainer. I also request BSN to create a larger bag of this product ( maybe a one of 7 or 8 Kg). When we order it internationally, we can't order so many bags due to restrictions. So if we have a larger quantity available, we are good for a longer tim to use it. Once again, the best of the best products I have ever seen! super taste, super results!!

Honestly, If flavor is your deal breaker, try mixing it with fresh fruit in a blender. Taste aside, no shake ever in the run of protein shakes were outstanding. I used this for a 6 month cycle before as my base weight is around 155 (6'0) and it worked extremely well. My body type is easily the hard gainer/ mesomorph and it began to recover much better. It allowed me to maintain training splits 3 or 4 days a week, plus cardio on top of work and school. I was nearly 175 by the end of my cycle, but I can't guarantee everyone elses body responds the same. It fits me and my training. Now serving the military, I will use it again to supplement strength training and recovery for our long distance runs and HIIT. It is not a miracle supplement and it doesn't simply produce muscle. But by far the most effective protein I have used. And I tried the BSN original True Mass, as well as ON, and Cellucor. But I can say that if your body hasn't been conditioned with a proper diet and continued protein, it won't do you any good.

This is a solid product, but I'm mostly indifferent to it. I tried the chocolate milkshake after finishing my bag of ON Serious Mass, and I preferred Serious Mass. The texture in this is a little too thick for me, even when used with a blender in milk or water, and the taste is a tad too sweet (but then mixing it with anything else like oats or peanut butter and it's like there's no taste at all, which is weird). I prefer it to the vanilla flavor I got two years ago, which started to taste gross after the first few servings, but still. I didn't notice much weight gain from this like I did with Serious Mass, and yes, I do know this is a supplement and not a replacement for my whole diet. I'm making my own weight gain shakes now since it's much cheaper for the same amount of calories and better ingredients, but if I do pick up another gainer, it'll probably be Serious Mass again unless Gold Standard Gainer is on sale. Good luck to those that do enjoy this product and get noticeable results from it.

I love this gainer! I chose this as I wanted a change from Mutant Mass which I had been using for around 6 months straight. The True Mass mixes excellent, tastes amazing in chocolate and helps me hit my macros. I have 2 half servings daily, one for breakfast and one post workout. I have gained around 3-4 pounds from my first bag.
