William Thomas has had a lifelong interest in exercise and sports performance, particularly cycling. William earned his BS in Health Science, MS in Kinesiology, PhD in Health & Human Performance, and Nutritionist Certification (Stanford University). Past certifications include Certified Strength and Conditioning Specialist (NSCA) in 2009 and certified fitness trainer (NESTA, NFPT, and NASM) in 2006/2007. His research on caffeine and cycling performance has been published (Medicine, Science, Sports & Exercise journal) and presented at the Southwest and National Conference of the American College of Sports Medicine. In addition to scholarly work, William is an accomplished cyclist having won numerous California state titles (XC and TT).

William’s vision is to provide athletes with an affordable and viable alternative to using illegal drugs. All ingredients are WADA/USADA legal and manufactured in a Kosher facility in California. The protocols and dosages in our products are backed by peer-reviewed science, not hearsay, or marketing hype. We don’t believe in snake oil.

Although ESN continues to help individual professional athletes worldwide, we prefer not to tax you in order to pay for large marketing efforts in order to provide the best science-backed sports nutrition at an affordable price. We believe there are no competitors that offer products similar to ours at the same price. Some competitors do not follow our vision and charge nearly twice as much (per bottle/lb.) for a similar product (ESN Fuel Hydration vs. Skratch Exercise Hydration and Osmo Active Hydration).
