BSN TrueMass Reviews

Joe P

True mass was amazing for me. I gained 13 pounds on my first tub and actually looked forward to drinking my shake unlike several other gainers i've tried.

Ryan B

Put decent size on, as well as a gut but that was expected, 3 scoops was a bit hard to keep down but not the worst product.

Kyle R

I used this for gaining weight while working out, and have tried it once. Pros: -Excellent Flavors -Easy to mix Cons: -Didn't add as much weight as other gainers -Too expensive to other quality competitors Will I buy again? -Possibly, depending on price.




Mix 3 scoops with 16 oz of cold water or beverage of your choice. Vary the amount of liquid to achieve desired consistency. Drink 2-4 servings daily or as needed to satisfy your protein or mass gaining requirements. To increase your protein and calorie intake per serving and to achieve an amazing milk shake taste, use milk.
