Nature's Aphrodisiac, Backed by Science​

Whether you use sex for procreation or recreation, this herb makes everything better, from libido to erections to fertility.​

We’ve always known that Longjack (Tongkat Ali or Eurycoma Longifolia) raised testosterone levels. We knew it prevented testosterone from converting to estrogen, and we knew it freed up bound testosterone so that it was available to muscles. We also knew Longjack led to better erections, but we thought that was just a nice side effect of the testosterone-fueled boost in libido.

Now we know that Longjack increases erectile strength through an entirely separate mechanism that works independently of testosterone. When combined with its other attributes, that qualifies Longjack as an herb that could legitimately be called an aphrodisiac.

Elevated Testosterone and More​

Up until recently, we thought that Longjack’s sexual effects were solely related to two particular quassinoids. These two quassinoids – eurycomanone and 13-alpha- (21) dihydro eurycomanone – elevate levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which direct the testes to crank out more testosterone.

Longjack increases testosterone levels further through two additional biochemical mechanisms. It both blocks the conversion of testosterone to estradiol (thus ensuring higher levels of testosterone) and selectively controls the conversion of DHEA to testosterone.

That explains why we thought Longjack led to better erections. Little did we know that a separate mechanism was involved, one that’s far more reliable than just what might occur with elevated T levels.

Erectile Integrity​

An erection is a marvel of hydraulics. Initially, an excitatory thought or external stimulus sends chemical messages to the arteries in your penis. The arteries relax and allow a tremendous amount of blood to flow in. The veins then constrict, which pressurizes the penis and sends it skyward.

One of the chemical messages that instigates erections is nitric oxide. Another is a family of chemicals known as rho kinases (ROCKs). When you inhibit ROCK, you get bigger and stronger erections. Longjack inhibits ROCK-2, an action that might explain the herb’s use as an “aphrodisiac” and to treat sexual disorders. The strong erections attained through Longjack use might also be the result of synergism between elevated testosterone and ROCK-2 inhibition.

Despite all that happy news, there’s more to a healthy reproductive system than elevated serum levels of testosterone and firm erections. There’s also fertility. Longjack plays a big role in that, too.

Firing Blanks​

Almost 15% of US couples are infertile and about half the time the problem lies with the man. One meta-analysis revealed a general downward trend in sperm count and semen volume over the last 50 years. Numerous studies, however, found that Longjack increases human and animal semen volume, sperm count, and sperm motility:

• One study showed that daily doses of 300 mg. of Longjack led to higher scores in erectile function domain, sexual libido, seminal fluid analysis, sperm motility, and semen volume. (Ismail. et al)
• The sperm counts of rats at varying doses of Longjack increased by 78.9, 94.3, and 99.2 % over control. (Chan, et al)
• In men 40-65 years old, 12 weeks of Longjack supplementation led to significant improvements in scores for “sexual intercourse attempts,” erection hardness scale, sexual health inventory, and the aging male symptom scale. (Chan, et al)
• Longjack increased spermatogenesis and sperm counts of rats in 14 days, reversing the effects of estrogen. (Wahab, et al)
• 350 patients who were given 200 mg. of Longjack per day showed significant improvements in all semen parameters, allowing for 14.7% more “spontaneous” pregnancies. (Tambi and Imran)
• Male rats given Longjack increased testosterone concentrations by up to 30.2%, along with exhibiting increases in total sperm concentration, motility, and vitality. (Solomon, et al)

How To Use Longjack​

First, use the LJ-100 version. LJ100 Longjack was developed and patented by the Government of Malaysia and the Massachusetts Institute of Technology. In short, it’s the one that works.

Second, only use the kind formulated in a self-emulsifying delivery matrix designed to get all active fractions into the body. The microemulsion is a game-changer for complete absorption.
