LastLonger is an erection promoter by reducing the secretion of stress hormone Adrenaline (epinephrine) by the drenal medulla, blocking the adrenaline receptors (bioelectric cells) in the prostate, enhancing the acetylcholine (ACh) and norepinephrine (NE) seccretion from the parasympathetic and sympathetic neurons, respectively, through powering the liver (chemical factory) function, and elevating the testosterone level in the bloodstream.
It uses a power erection and the reduction of the sympathetic function by mitigating the adrenaline action on the prostate, to achieve ejaculation delay. It is also an aplha blocker that blocks the adrenaline receptors. Ginsengs can reduce the stress hormone production!
To avoid continuing LastLonger, you must change diet, including at least 8-oz seeds/nuts/soybeans every day, having more fresh vegetables and fruits, and reducing your beef intake no more than 1/4 lb and dairy product no more than 16-oz milk or 3-oz cheese.
Your prostate tissues bind too much DHT and testosterone that heat up your ejaculation controller!
Let plant hormones coat your prostate tissues and unbind DHT and testosterone from androgenic receptors there.
In one month, you will become a different person in ejaculation control.

You need testosterone to be burned into DHT for powering up your nervous system for erection, but you don't want testosterone and DHT to be binded in the prostate tissues, which induce pains and tension in your crotch area. Plant hormones will help you out down there. The excess DHT and testosterone in the prostate area promote the sympathetic action to increase adrenaline secretion for either premature ejaculation or erection withdrawal.

During Intercourse , you must also practice sexual ChiKong to switch the sympathetic function to parasympathetic finction, and to channel your excess sexual energy from your prostate back to your brain via your spinal cord and Governing Vessel (the Master Accupencture Energy Channel).
