The synergy between Jack3d and PowerFULL is unreal! Carbohydrates blunt Growth Hormone release, this is known but often over looked. This is where the USPlabs Jack3d/ USPlabs PowerFULL stack shines!
Jack3d is is carbohydrate free, therefore the true effects of pre-workout PowerFULL will be felt! The increase in natural Growth Hormone release will cause for serious strength gains that will lead to increased LBM. You will see increased vasodilation, in combination with the AAKG in Jack3d. BUT, the synergistic 'Mind-Muscle Connection' that you will feel when dosing these products together will shock you. You will literally be able to feel your muscles doing the work, easier and more effectively. Many users report this effect while using one product or the other but when they are combined, the effect is exponentially increased!
Not to mention USPlabs PowerFULL's other effects like Increased natural Growth Hormone production, Increased Testosterone production, Increased Dopamine and Serotonin levels, Increased Skin Tone, Increased Quality of Life feeling and Significantly Improved Recuperative Sleep, etc.
Again, you can use USPlabs PowerFULL with other pre-workout products for the this synergistic 'Mind-Muscle Connection' but the fillers (sugars/malto/dextrose, etc) may blunt the Increased natural Growth Hormone production which may cause less intense effects.
