🧪 Formulation Notes

3 products in 1 pack GNC AMP Strength Vitapak Program delivers the power of three science-based formulas to help you achieve your daily nutritional goals as you build muscles and get stronger. Increase strength & fuel your muscles 189% more efficiently Because Creatine HCI 189 is clinically shown to be absorbed into your muscles 189% more efficiently than creatine monohydrate, you can increase strength & performance with 1/4 of the dose. When used in conjunction with regular resistance training

Move 9.5x more weight In a randomized, double-blind, clinical study of 57 healthy, young adult males, subjects who took GNC AMP Creatine HCI 189 containing only 1.25 grams of the PEG-Creatine System significantly improved leg press 1-RM performance by 54.3 pounds, while subjects receiving 5 grams of creatine monohydrate significantly improved performance by 52.3 pounds and the placebo group showed no significant improvement at 5.7 pounds at the end of the study.

Vitapak program for performance + muscle support Increases strength & fuels your muscles 189% more efficiently In a clinical study of 17 healthy young adults, muscle biopsy results revealed that GNC AMP Creatine HCI 189 resulted in 189% greater muscle creatine uptake relative to benchmark amounts of ordinary creatine monohydrate powder.
