Make Your Gains LEAN with Mass JYM
High-quality protein, carbohydrate, and fat blends make Mass JYM a premium-level mass gainer.
Ideal Carbs-to-Protein Ratio
High-Quality Carbs and Fat
Award-Winning Protein Blend
Protein was by far the easiest part of formulating Mass JYM. Why? Because I’d already done the legwork with Pro JYM! No need to reinvent in the wheel. Mass JYM has the exact same protein blend as Pro JYM: 50% micellar casein + milk protein, 40% whey, and 10% egg white protein. This particular blend will help maximize muscle protein synthesis (MPS) around the clock for greater gains.*
Mass JYM for the Win!
With protein, carbs, and fat all in optimal ratio and from quality sources, Mass JYM is the premier product for packing on size – lean size, that is!
