6 grams of Branched-Chain Amino Acids (BCAAs)

  • The BCAAs are three amino acids-leucine, isoleucine, and valine-that share a common structure.
  • Leucine is the most critical after workouts because it stimulates muscle protein synthesis (i.e., muscle growth) by activating the mTOR complex.*
  • It also increases insulin release, which drives more amino acids, creatine, and carnitine from Post JYM into your muscle cells.*
  • Having a 3:1:1 ratio of leucine to isoleucine to valine in a post-workout product, such as in Pre JYM, provides an extra bit of leucine for maximal muscle growth without compromising the critical role that isoleucine and valine play in this process.*

JYM Post JYM Carb
  • Research confirms that working out for as little as 30 minutes can deplete muscle glycogen levels by more than 40%. Intense workouts lasting 60-90 minutes would deplete muscle glycogen levels considerably more.
  • When carbs are consumed immediately postworkout, a supercompensation of muscle glycogen stores is possible. In fact, delaying carb consumption by just 2 hours has been suggested to reduce the rate of glycogen replenishment by 50%.
  • Another benefit of high-glcyemic carbs is the insulin spike that they deliver. A post-workout increase in insulin helps maximize the uptake of creatine and carnitine (included in Post JYM Active Ingredients Matrix) by the muscle cells.*
  • Dextrose is one of the fastest-digesting carbohydrates you can consume. It's essentially glucose (what blood sugar is) and therefore needs no digesting and is absorbed by the body almost immediately.*

JYM Pro JYM

The 24 grams of protein in each scoop of Pro JYM contain the following:

  • Whey Protein Isolate: 7.5g
  • Micellar Casein: 7g
  • Egg Albumin: 2.5g
  • Milk Protein Isolate: 7g (5.5g Casein, 1.5g Whey)

The rating is on price only. Doesn't make sense. This 4lb stack is 135$ and the 2lb stack is 100$. Difference of 35$. A 2lb bottle of pro is 32$. So buying the 2lb stack and a separate 2lb pro is 3$ cheaper than buying the 4lb stack that have the same pre, post, and carb servings. Am I missing something or should the price of the 4lb stack be adjusted?

I tried this stack and was impressed with the results. It was expensive but I will buy again. Listing out the ingredients made the price worth it. Pro JYM mixes very thick but tastes okay.

I highly recommend this #Jym stack! It has been since 2008 since I've been to the gym, BUT I didn't forget the importance of supplements. That is why, when I got back into working out, I needed the best on them market for workout supplements. SO, needless to say, I went with the #Jym stack! ONLY the BEST! Blessings, Ryan T.
