It doesn’t matter if you’re an athlete, serious weight trainer or hard gainer, if you’re looking to pack on serious muscle, look no further than our Ultimate Muscle-Building Stack. Designed by Dr. Jim Stoppani this award-winning stackis specifically designed to support workout performance, help kickstart recovery, and increase protein feedings so you can build and maintain maximum muscle size*.

But that’s not all…

To help put your body in an ideal muscle building state the Ultimate Muscle-Building Stack also includes a downloadable digital copy Dr. Stoppani’s Muscle Building Nutrition eBook. This comprehensive guide takes the guesswork out of muscle building nutrition by giving you the precise ratio of proteins, carbs and fats you’ll need to eat at each meal, each day to keep your muscle building machinery primed for gaining lasting lean muscle size and strength*.

This stack provides:

• The ultimate muscle-building value: a 10% savings on the supplement bundle and free ebook ($9.99 value).
• A science backed, all-inclusive supplement regimen – no need to buy any stand-alone ingredients like BCAAs or creatine*.
• An easy-to-use nutrition guide that tells you exactly what to eat and when for lean muscle gains – no more confusing and restrictive diets that are impossible to stick to*.
• More muscle through an ideal blend of fast-, medium-, and slow-digesting proteins and amino acids shown to boost muscle protein synthesis (MPS)*.
• More intense, productive workouts with a true performance pre-workout*.
• The recovery-boosting ingredients you need after intense workouts to start the muscle repair and rebuilding process and optimize MPS*.
• The omega-3 fats you need, via a high-potency fish oil product, to support the muscle building process*.

JYM Ultimate Muscle-Building Stack Product Overviews


Our best-selling pre-workout, Pre JYM, will allow you to train harder and longer in the gym, which will ultimately lead to better gains. Pre JYM also contains ingredients that directly enhance muscle size*.

The 13 ingredients in Pre JYM collectively increase muscular strength and power (creatine, beta-alanine, betaine, beet root extract); enhance energy, focus, and alertness (caffeine, Alpha GPC, Huperzine A, l-tryosine, taurine); increase stamina (creatine, citrulline malate); and blunt feelings of fatigue (caffeine, BCAAs, beta-alanine)*.

As for direct muscle building, creatine and betaine both initiate growth through increase muscle protein synthesis. Then there’s leucine, the most anabolic of the three branched-chain amino acids (BCAAs), that’s been shown to drive MPS for great muscle gains*.


To maximize muscle growth, you need a lot of protein. As Dr. Stoppani recommends shooting for 1.5 grams of protein per pound of bodyweight per day; that’s 300 grams of protein daily for a 200-pound individual. Have you ever tried to get 300 grams of protein per day from whole food alone? I have,and it’s a bit excessive. That’s where Pro JYM comes in.

Pro JYM isn’t just about convenience, though. Its precise blend of whey, casein, and egg proteins provides the ideal mix of fast-, slow-, and medium-digesting proteins Research has shown that this type of blend enhances muscle protein synthesis (MPS) and muscle growth better than powders that contain only whey*.

Post JYM BCAA+ Recovery Matrix

Muscles don’t grow while you train – they grow at rest, after getting a full recovery from intense workouts. Enter Post JYM, an advanced recovery formula featuring BCAAs along with several other key muscle-building agents.*

Five ingredients in Pre JYM are also found in Post JYM: BCAAs, creatine, beta-alanine, betaine, and taurine. All of these have been shown to have beneficial effects when taken pre-workout and post-workout.*

The main ingredients exclusive to Post JYM are glutamine and l-carnitine l-tartrate. Research suggests that glutamine supports recovery between workouts, and it’s also critical for normal immune function – an important factor for those who train hard.* The other ingredient, l-carnitine l-tartrate, enhances recovery after exercise, due to its potential to support natural hormone uptake in muscle and therefore promote exercise recovery*.

Omega JYM

You may be surprised to find Omega JYM, our high-potency fish oil, as part of a muscle-building stack, but there’s good reason for its inclusion.

Fish oil is usually mentioned in the context of promoting heart health, joint health, and even fat loss (as in our JYM Ultimate Fat Loss Stack), but researchhas shown that taking 1,500 mg daily of the omega-3 fatty acid docosahexaenoic acid (DHA) increases MPS following a high-protein meal. This 1,500 mg amount is the exact dose of DHA you get in just 4 capsules of Omega JYM.
