Stoppani's Pre-Jym is the best preworkout I've ever tried

[KGPL]

Stacked with noxygen it is INSANE. The pumps are unbelievable. I wasn't even chasing a pump, but my tri's and delts inflated like no other.

1 scoop pre jym, 2 noxygen. Taste was great as well, like a cherry pie with ice cream. Odd description, but the best I could come up with.

I'd scratch the BA, add an extra 1g of Betaine to get the clinical dose, switch out CM for L-citrulline, and probably take out the NAC as well.

I thought CM was superior to plain L-citrulline. I've taken the plain L form before in high doses and didn't feel as though it did squat. But the malate form at 6-8 grams gave me head pressure.

CM is L-citrulline bound to a malate at either a 1:1 or 2:1. It was originally thought that CM was superior, but it has now shifted to straight L-citrulline.

I'm not arguing with you, but where is the shift occurring and which companies are switching back to the plain L-form?

Stoppani explains here why he suggests at least 6g of CM:

In the gym, my other lab, I’ve found that when working with doses found in most supplements, anywhere from 1-3 grams, L-citrulline provides more of a potent pump than citrulline malate. Citrulline malate, on the other hand, provides more of a strength and endurance boost during workouts than L-citrulline does. However, if you increase the dose of citrulline malate (with a ctrulline malate product that delivers citrulline at a 2:1 ratio of malate) to about 6 grams or more, it delivers significant improvements in muscle strength and endurance while increasing the muscle pump like you wouldn't believe. Let’s take a closer look at the research that further supports what I’ve seen in the gym.

Citrulline vs. Arginine

Aaaaand it's sold out everywhere now that I'm ready to order.

I know! I had to order All-In because I can't find any Pre-Jym.

I can understand why. This stuff's the cat's ass. I haven't seen a single person claim this stuff didn't deliver.

Athletix/PES for starters.

Citrulline vs. Arginine

His point regarding additional malic acid for the Krebs cycle for PCr production is pretty much moot because of the inclusion of CrHCl. That being said, I've never been a fan of any "pump" product from an ergogenic perspective. They're almost purely cosmetic with little to no sarcoplasmic or myofibrillar hypertrophy.
