GNC Pro Performance® AMP Amplified Stamina™
Dual release thermogenic powder proven to amplify calorie burning by 619%^ and boost stamina by 12%.^^ Concentrated formula features 1.5g BCAAs, 1g beta-alanine, resVida™ Resveratrol and two-hour extended release OT²™ arginine to maximize blood flow.
^In a double blind, randomized, placebo controlled cross-over study, 33 male and female subjects exercised on two occasions. On one occasion the subjects took the thermogenic blend in this formula 60 minutes before exercise and on the other occasion, they took a placebo. When the subjects took the thermogenic blend, they burned 6 times (619%) more calories pre-exercise, 5% more calories during exercise and over 3 times (373%) more calories post-exercise compared to when they took the placebo.
^^A study of 29 physically fit and healthy young adult male subjects averaging about 4 hours of exercise a week cycling to exhaustion at 80% VO2 shows that these individuals were able to increase performance measured by time to exhaustion by nearly 5 minutes (12%) longer than taking the herbal blend in this formula than when taking placebo.
