Introducing the Marathon Endurance Stack, inspired by the training routine of Nutristat athlete Walter Lazo as he prepares for the 2026 Marine Corps Marathon. Walter combines high-mileage endurance work with serious strength training, making recovery, hydration, muscle maintenance, and consistent performance essential parts of his routine.
The Marathon Endurance Stack brings together the same four Nutristat products supporting Walter throughout his training: 27-serving PÜR NATIVE™, 60-serving Creatine, Crea Script™, and Amino Script™, with your choice of available flavors.
Whether you're building toward 26.2 miles, increasing weekly training volume, or simply pushing your endurance further, these four complementary formulas are designed to help fuel the work, protect hard-earned muscle, and keep you ready for the next session.

PÜR NATIVE™ provides premium, highly bioavailable Native Whey protein isolate to support muscle repair and recovery after demanding training. When the miles start adding up, getting quality protein back into the body becomes just as important as the work itself.
Creatine uses 100% Creapure®, patented and trademarked from Trostberg, Germany, for an exceptionally pure and transparent source of creatine monohydrate. Creatine helps support ATP production, muscular strength, power output, and recovery, making it valuable for endurance athletes who still need to maintain strength through a demanding training block.
Crea Script™ takes creatine performance further with an advanced formula designed to support creatine uptake, muscle hydration, nutrient delivery, and sustained performance. Its highly digestible rice-based carbohydrate system provides a smarter alternative to the cheaper carbohydrate fillers found in many performance formulas, especially when digestive comfort matters during high-volume training.
Amino Script™ delivers essential amino acids to support muscle tissue during long and demanding sessions, helping reduce muscle breakdown and promote recovery as training volume climbs.
Four products. Four different jobs. One goal: keeping your body ready for the next mile.
Train smarter. Recover better. Fuel every mile.
Bundle includes the 27-serving size of PÜR NATIVE™ and 60-serving size of Creatine. Crea Script™ and Amino Script™ flavors may be selected from available options.
