The new Jack3d Advanced formula is much like the original except for the loss of DMAA and addition of Yohimbe and Norcoclaurine HCl. Yohimbe is a common herb used in many sports supplements as well as male vitality supplements. It’s desired effect is increased endurance through blood pressure modulation and testosterone encouragement. The other ingredient of interest, Norcoclaurine HCl is very new to the industry and little absolute knowledge is documented. This ingredient is believed to be another broncho-dilator as well as circulatory enhancer, reducing thrombosis.
