Muscle Growth* - Strength* - Energy* - Endurance* - Recovery* - Refuel*

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.

MassJym Apple Fritter
Great product that is not just for mass gaining. The product has a great taste but is a little too thick for a shaker when mixed with milk and anything but water. Can fit any diet and good for a quick meal on the go.

MassJym - Excellent, But GNC service so out-dated.
Had to write a review for GNC's most archaic service that exists as of 2018 !!

NOTE : This is REVIEW of GNC's fulfillment service ( NOT for JYM Supplements, which are awesome no matter what you try !)

Had I purchased this at Amazon or the product would have been at my doorstep in 2 days !
Here ? We have to wait a full 10 days !!!
If this was 1996 - I would have been so elated just to be able to order online to not have to visit a store !! But sadly it is 2018 and waiting 10 days for ANY product is simply in-acceptable !

Bye bye GNC ! Hello
