Traditional Chinese Medicine has the very important concept of "jing", which can be defined as "core energy" or "essential fluid". Jing is the source which powers us, but it is depleted by stress, bad diet and sexual excess. In the case of men, this means over-ejaculating, which can weaken you and lead to lethargy, sore joints, back pain and loss of drive. However, there is a powerful natural solution. Jing Builder replenishes male sexual energy and jing fluid. Formulated using both amino acids, and traditional Chinese and Tibetan herbs, it increases potency, amplifies libido, intensifies climax, and ensures a faster rebound. This supplement is made in an FDA certified lab in the US. Return to your youthful foundation! 60 capsules $30.00 (Order# 1045)
