Product Overview

JYM Post JYM Active. Active Ingredients Matrix. The Ultimate Post-Workout Formula! Recovery*. Growth*. Refuel*.

"JYM Supplement Science combines real science with real ingredients to deliver unreal results. Post JYM, my revolutionary post-workout recovery formula, delivers the exact ingredients you need after every workout to ensure those unreal results.* It's a powerful post-workout cocktail scientifically designed to help you boost repair, maximize recovery, and build more muscle.*

Many of the ingredients in Post JYM Active Ingredients Matrix mirror ingredients in my Pre JYM blend. These ingredients include BCAAs, creatine HCL, beta-alanine, betaine, and taurine. These five ingredients need to be consumed before and after every workout for maximal performance and muscle growth.* Thus, Pre and Post JYM are designed to work in concert. Take Pre JYM to train like an animal; use Post JYM to recover like a pro.*

Post JYM Active Ingredients Matrix also contains carnitine and glutamine, which are important to quickly ramp up post-workout repair.* In addition, you can also purchase Post JYM dextrose separately. This way Post JYM lets you control your carbs and customize your post-workout protocol. By keeping dextrose separate, Post JYM lets you control your carbs and customize your post-workout protocol.

Like every JYM product, Post JYM contains no proprietary blends, proper dosing on all ingredients, no "abbreviated" formulas, no concentrates, and no BS. All eight of the ingredients in Post JYM are critical for recovery.* There is no filler. Every single ingredient is included at the best dose to optimize repair and growth.* That's the power, and promise, of Post JYM.

Prepare to experience the combined power of real science, real ingredients, and unreal results."

Post JYM Active Ingredients Matrix Features
  • Full doses of 8 science-backed ingredients
  • 6 grams of BCAAs in a 3:1:1 ratio that enhances muscle growth*
  • 3 grams of glutamine for better recovery and growth*
  • 2 grams of creatine HCL for greater strength, endurance, and muscle growth*
  • 2 grams of CarnoSyn® beta-alanine to boost muscle power, strength, endurance,  and muscle growth*
  • 2 grams of Carnipure L-carnitine L-tartrate to aid recovery and put more testosterone  to work for you*
  • 1.5 grams of betaine for greater power and strength during workouts*
  • 5 milligrams of BioPerine® to enhance absorption of nutrients for even better results*

Under the Microscope

Let’s take a closer look at each of the eight ingredients and doses used to make Post JYM a revolutionary recovery formula.*

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.*
2 grams of Creatine HCL
  • There are hundreds of studies suggesting that creatine supplementation leads to significant gains in muscle strength and power, as well as muscle growth.*
  • Creatine HCL is made by attaching a hydrochloride (HCL) group to creatine.
  • Adding the hydrochloride group lowers the pH of creatine, making it more acidic. This drastically increases creatine's solubility in fluids, which increases its absorption and reduces stomach issues.*
  • Clinical research suggests that one of the best times to get a dose of creatine is after workouts. This is especially true when consuming creatine along with ingredients that spike insulin levels, such as leucine and dextrose, which are included in the Post JYM Active Ingredients Matrix and Post JYM Dextrose.*
2 grams of CarnoSyn® Beta-Alanine
  • Beta-alanine is an amino acid that gets taken up by muscle fibers and combines with the amino acid histidine to form carnosine.*
  • Research suggests that carnosine increases strength and power, improves endurance and recovery, and muscle growth.* This is especially true when taken together with creatine, as in Post JYM.
  • One of the best times to get a dose of beta-alanine is right after workouts when muscle fibers are primed to utilize nutrients.* Taking beta-alanine along with leucine and dextrose, as in Post JYM Active Ingredients Matrix and Post JYM dextrose, further enhances its uptake to keep your muscle carnosine levels maximized.*
2 grams of Carnipure L-Carnitine L-Tartrate
  • Studies suggest that L-carnitine L-tartrate supplementation enhances recovery after exercise with as little as 1 gram.* The better recovery is likely due to carnitine’s ability to boost nitric oxide (NO) production and therefore increase blood flow to recovering muscles, as well as its ability to induce an increase in muscle oxygen consumption.*
  • Another benefit of L-carnitine L-tartrate is that it increases the amount of androgen receptors in muscle cells.* These are the receptors that testosterone binds to inside muscle fibers to instigate muscle growth.* Since testosterone rises following a workout, having a higher concentration of androgen receptors in the muscle cells can help ensure that more of that testosterone is used to build muscle.*
  • Since carnitine requires insulin for entry into muscle cells, it’s best to supplement carnitine with ingredients that spike insulin levels, such as leucine and dextrose, which are both in Post JYM Active Ingredients Matrix and Post JYM dextrose.*
3 grams of Glutamine
  • Glutamine is one of the most abundant amino acids in the body and is important for muscle recovery and growth.*
1.5 grams of Betaine
  • Betaine, also known as trimethylglycine (TMG), is a modified version of the amino acid glycine.
  • Betaine supplementation has been suggested in clinical studies to improve muscle strength and power production, increase the number of reps done with a given weight, and improve endurance.*
  • University of Connecticut researchers reported that supplementing with 1.25 grams of betaine twice per day for two weeks increased bench press power by 20 percent and muscle force on the bench press by 25 percent.*
  • Betaine has also been shown to significantly increase protein synthesis following workouts as compared to a placebo. This can help lead to greater muscle growth in the long term.*
1,000 mg of Taurine
  • Taurine is a specialized amino acid that is important for endurance and muscle strength.*
  • Exercise depletes taurine levels, thereby impairing strength and endurance, so it’s critical to get a dose of taurine after every workout to replenish what was lost.*
5 mg of BioPerine®
  • BioPerine® is a patented extract of the fruit of black pepper, or long pepper, that contain standardized amounts of the active ingredient piperine.

  • 7 Mandarin Orange

Bought these products, both of the flavours. The Rainbow Sherbet is like having Skittles in your bottle of water. The Mandarin Orange is good but tastes like Crush Orange Sode minus the bubbly effect of a carbonated beverage.

Is the post jym active fruit punch/watermelon ORIGINAL coming back? please sell both new and original..all the new jym flavors are TERRIBLE

  • 10 Lemonade
  • 10 Watermelon

The newly released Watermelon flavor is just as good as I remember it being from the previous release. I highly recommend this flavor to anyone. I enjoy it with or without dextrose added, of course with dextrose added its sweeter but this product gets the job done. It's Dr. Stoppani what else do you need to say or know? Lemonade is another great flavor. Same comments as above and it gets the job done as advertised. Get you some!!!

The only thing I don't like about the new flavors is how they taste soooo good on the first sip, then awful on the rest

  • 1 Fruit Punch

Unlike some other post work out drinks I've had this is the only one that doesn't leave me feeling like I've been ran over by a stampede. So clearly it is helping with recovery. However, I'm a bit concerned as the BCAA that are in this, aren't hydrophobic as I would expect them to be. The fruit punch is an awful taste that I use 32oz of water with. Even with that much it tastes like a liquefied jolly rancher. I have to power through each time.

Really bummed out that the old flavors aren’t available. The new flavors just can’t compare. I LOVE the old Pre/post/pro JYM flavors, but really dislike the current lineup. JYM has been my go-to supplement line since it launched. Fantastic ingredients and proper doses. Bodybuilding...Jim....PLEASE bring back the old flavors!!! Listen to the people.....

Wonderful product, but the new flavors have lost their taste making me switch to a different line. I hope this changes in the near future as I feel this product gives me the best power.

Post Jym is the best. Mixes well, tastes awesome in all the flavors I've tried (Rainbow Sherbet, Watermelon, and Lemonade), and has been crucial in my recovery and muscle building process. I like to use it as a pre-workout as well when I don't need the caffeine buzz or I'm working out late at night as most of the ingredients are the same as Pre Jym.
