Xendurance - Creatine JB (Josh Bridges)

Xendurance's Creatine JB

An athlete who desires to increase his or her lean body mass and peak strength understands supplementation with creatine is the effective way to reach performance goals. How? The creatine supplement works well to enhance anaerobic performance, controls acidity in muscles and helps mitigate the effects of lactic acid accumulation.

For athletes discovering Creatine JB, a product developed and tested by our own, Josh Bridges, they find this supplement from Xendurance to be a game changer in their improved athletic performance and quick recovery.

What Others Are Saying About Creatine JB

"Over the past few years, I've used numerous brands of creatine...But it wasn't until I bought Josh Bridge's creatine on a whim at the 2014 CrossFit Games, that I truly noticed a difference in my performance…

Xendurance and Josh Bridges have put out an excellent product that really works,and if you're looking for something to boost your training, Creatine JB is definitely worth trying."

"Creatine JB gives me endurance and recovery so I can hit my oly lifts more often and harder." Cameron, Olympia, WA

"Xendurance Creatine has been a game changer in my routine. The benefits are evident within the first couple weeks…with full recovery including being able to compete in back to back competitions. I attribute all to the Xendurance products and especially the Creatine." Astoecklin, Phoenix, AZ

"I believe I have found a winner when it comes to my personal supplementation with the product Creatine JB. This creatine was developed by Xendurance with the help of CrossFit; Josh Bridges (a three times CrossFit athlete and former Navy Seal).

I enjoyed this product. I usually can only work out at the end of the day after responsibilities have been taken care of such as school and work, so by the time I get to the box I am looking for something to help increase my stamina, strength output and energy for the RX that is looming ahead. Creatine JB delivered to this end, and the taste was excellent as well!" Spencer, Contributor of

Josh Bridge's Creatine-JB uses only Creapure™, 100% pure, creatine monohydrate, enhancing uptake and bioavailability, thereby allowing your muscles to quickly absorb and utilize creatine faster. Creatine can help support protein synthesis which helps muscle growth. Every scoop of Creatine-JB gives you 4 grams of 100% pure, clean creatine and 1000mg of lactate.

Xendurance has pledged a percentage of Creatine-JB sales to Josh Bridge's requested foundation. We are honored to help Josh contribute to The Brendan Looney Foundation.

When athletes train and compete, it can ultimately lead to a wide range of internal disruption, such as:

  • Increased body and muscle acid
  • Muscle inflammation
  • Muscle trauma
  • Micro muscle tears
All of these results can lead to muscle burn, muscle soreness, and a longer recovery time.

Xendurance is the solution to reducing muscle acid, micro muscle tears, and muscle burn. Most importantly, these claims are backed by science.

Open Label CK STUDY
[Watch the video]

An open-label test was recently conducted to track changes in CK levels along with muscle trauma and micro muscle tears in athletes.

A group of 31 athletes participated in this study.

They were required to perform FRAN twice over the course of a seven-day period. After completely the first workout, every athlete received a seven-day dosage of Extreme Endurance. They were instructed to keep their current diet and training schedule unchanged.

On Day 7, the participants returned to complete the second test. On both the pre- and post- testing days, blood samples were taken to quantify and record the participants' CK levels for muscle damage and trauma.

The results of the test were amazing.

Testing proved that using Extreme Endurance over a seven-day period decreased pre-workout CK levels by an average of 16.9% and decreased post-workout CK levels by an average by 63.55%! That is a game changer in the reduction of muscle damage and trauma.

In addition, 29 of the 31 athletes performed better in the second workout with an average increase in performance by 8.55%.

Regardless of your sport of method of training; the study proved that by using Extreme Endurance, you will dramatically decrease muscle damage and muscle trauma along with decreasing muscle soreness and muscle burn. These results can lead any athlete to quicker recovery times and an increase in performance levels.
