Product Information




30g Protein - 34g Carbs - 300 Calories - 4.5g Fiber - <1g Lactose

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.

It is so delish! Tastes just like an apple fritter doughnut and is very filling. Mix to your liking if you like it runnier or thicker.

I have made lots of purchases at GNC over the years. Some that were on point and some that I wished I hadn't gone over 30days. This product is on point! I have been using it on/off for nearly 3 months. I used it daily for 30+ days as my lunchtime meal replacement and noticed a huge difference in muscle definition and the recovery is AMAZING! Using it now every 2-3 days and the difference is feeling sore after a really good workout. I highly recommend using this product daily to achieve your desired results. Let's not forget to mention the great flavor/taste...Tahitian Vanilla Bean is the best and Apple Fritter is close second but it is slightly sweet.

I hope my review of this product helps you decide to give this product a try.
