TEST SUBJECTS BUILT 8.8 LBS. OF MUSCLE!
Amino 4XL™ SX-7® Black Onyx™ also contains a clinical dose of PEAK ATP®. This breakthrough ingredient increases anabolic signaling by activating the mTOR pathway. It also increases skeletal muscle calcium influx and release, which leads to better muscle contraction for improved performance. Finally, PEAK ATP® supports vasodilation and improves blood flow to deliver more oxygen and help you push through those last few reps!
Hard-training subjects who participated in a gold-standard, 12-week human clinical study at The University of Tampa using the exact same dosing protocol of PEAK ATP® as Amino 4XL SX-7 Black Onyx not only gained insane amounts of strength, they also made some serious muscle gains! Subjects gained 8.8 lbs. of lean muscle versus the placebo group, which only gained 4.6 lbs. in 12 weeks – that’s 90% more lean muscle! These were well-trained subjects who were recruited based on strict guidelines to ensure accurate results with hardcore weightlifters!
These subjects also increased their total strength (total strength on bench press, squat and deadlift) by an average of 121.9 lbs. during the 12 weeks versus an average of 49.4 lbs. for the placebo group.
This groundbreaking study was published in Nutrition & Metabolism and firmly put PEAK ATP® in the top tier of supplement ingredients!
