About Jym

Jim Stoppani’s JYM Supplement Science launched in 2013.

With his PhD in exercise physiology and thousands of articles in respected industry publications, company founder, Stoppani, is a famous name in the fitness and supplement industries. 

His career includes an 11-year stint as Senior Science Editor at Weider Publications, during which he edited pieces for Muscle & Fitness, Muscle & Fitness Hers, and FLEX. Stoppani has also written or co-written several books on fitness. These include ‘the Encyclopedia of Muscle & Strength’, and ‘LL Cool J’s Platinum 360 Diet’ – a New York Times bestseller.  

The doctor has even been a personal trainer and nutrition consultant to celebrities like Dr Dre, LL Cool J, Dwayne “The Rock” Johnson, and Mario Lopez (a star of “Saved by the Bell”).

The company is built on Stoppani’s reputation. The founder uses his clear knowledge to reinforce the idea that “science and quality” go into every one of his products. The website sells what it calls a “ground-breaking line of sports nutrition and physique enhancing products”.

In 2015, JYM Supplement Science won the Bodybuilding.com awards for “Most Innovative Brand of the Year”, “Best Pre-workout of the Year” for Pre JYM, and “Best Multivitamin of the Year” for Vita JYM. It also won “Brand of the Year” in 2018.

Pre JYM is perhaps the best-known product in the range. This pre-workout supplement has been tested and certified by Informed-Sport, a global quality assurance program. This is a “full manufacturing audit” that involves testing for ingredients banned by the World Anti-Doping Agency (WADA). Pre JYM has also received thousands of positive online reviews.

Meanwhile, Pro JYM is a protein powder that also boasts many positive reviews on respected industry sites. Yet another popular product in this brand’s range is Post JYM Active Matrix. This is a post-workout designed to boost recovery and to build and repair muscle after exercise. 

Other JYM Supplement Science supplements include vitamins, omega-3, ZMA, protein shakers and even branded clothing.
