Jim Stoppani’s official Mass Jym is here with a 1:1 ratio of protein and carbs

mass jym

Jim Stoppani confirmed late last year that he would eventually be launching his own version of the mass protein Mass Jym. There was a Mass Jym released at the beginning of 2017, although as Stoppani said that was not his official version.

Formula

Jim Stoppani’s long-awaited own version of Mass Jym has now arrived, and it is quite similar to the previous one which Bodybuilding.com seems to no longer list. Stoppani has gone with an even 1:1 ratio of protein to carbohydrates for Mass Jym packing 30g of each per serving to help with lean muscle growth.

The protein in Mass Jym comes from all the same sources as the protein powder Pro Jym, featuring a blend of micellar casein, milk and whey isolate, and egg protein. As for the carbohydrates, they also come from a well thought out 3:1 ratio low to high GI blend, featuring pea starch, isomaltulose, and oat fiber.

The other macros in Mass Jym include 5g of fat from a 1:1:1 ratio of saturated, monounsaturated, and polyunsaturated fat, with a gram of CLA. Then lastly, you have the calorie count sitting at just 270, which you can of course increase by double serving, giving you 60g each of protein and carbs, 10g of fat, and a total of 540 calories.

Available now

The first official Mass Jym or as the bottle says the “only mass gainer formulated and used by Dr. Jim Stoppani”, is now available over at Bodybuilding.com. A full 5lb, 31 serving tub will cost you $63.97 with three flavors to choose from in Chocolate Mousse, Tahitian Vanilla Bean, and Apple Fritter.
