Additional Information

My Guarantee My Mass JYM formula is the first gainer to use a non-proprietary protein blend, a non-proprietary carbohydrate blend, and a non-proprietary fat blend. The 1:1 ratio of protein to carbs works to help optimize lean muscle mass gains while minimizing body fat gain. Whether you use it as a meal supplement when on the go, or as a muscle gainer, you can be confident that every ingredient in this bottle was selected by me, as I design every JYM product for both myself and the rest of JYM Army.
