Stamina-RX Research Study

Stamina-Rx utilizes xanthoparmelia scabrosa, a natural source of Pyrazolo pyrimidinone (a core component of leading prescription medications for impotence). This component of the Stamina-Rx formula serves to effectively inhibit PDE-5 activity...induces smooth muscle relaxation to allow for increased blood flow and maximum arterial dilation., allowing the body to sustain an erection!

Another main component is Cnidium Monnier, which allows erections to be sustained longer by increasing nitric oxide release and inhibiting PDE-5.

Cnidium monnieri is a plant which grows in China (and possibly in Oregon) whose seeds are used in classical traditional Chinese medicine for skin problems and as a natural sex booster. Cnidium is known in China as She Chuang Zi. You may find cnidium seeds in bulk at Chinese pharmacies and some health food stores.

Cnidium seed contains several compounds including coumarins, osthol, imperatorin, glucides and hepatoprotective sesquiterpenes.

Preliminary studies show some of the compounds in cnidium may have anti-histamine, anti-itch, anti-fungal, and anti-bacterial effects, along with having an influence on the pituitary-adrenocortex axis. Additional studies on rodents indicate that cnidium may improve bone strength (coumarins from fruits of cnidium inhibit formation and differentiation of multinucleated osteoclasts of rats). In rabbits, a compound found in cnidium called osthol or osthole was found to help relax the corpus cavernosa of the penis, which would potentially help with blood flow and erections. Cnidium may also have anti-cancer properties. As of September 2004, no human trials have been published on Medline regarding the clinical use of cnidium.

Cnidium is available in bulk powder, however cnidium is currently not easily found by itself. Cnidium is most often found in combination with other sex enhancing herbs in formulations. Cnidium is also available in different extract potencies, for instance a 4:1 extract.

Stamina-Rx utilizes a compound that stimulates the production of nitric oxide, leading to the production of cyclic GMP (cGMP). It is the cGMP which ultimately affects smooth muscle relaxation, allowing the penile arteries to expand and fill with blood.

PDE-5 is an enzyme that binds to and digests cGMP.

If cGMP is digested too quickly, its "relaxing" effect on penile smooth muscle tissues will be reversed, causing the erection to weaken (in many cases this will happen so rapidly, it will appear as if no erection was ever present). Simply stated, PDE-5 can be a REAL erection killer.

Stamina-Rx is a new and improved formula comparable to Enzyte with some added benefits. Both formulas have the same high quality ingredients, however, only Stamina-Rx has added ingredients for optimum performance.

Stamina-Rx also utilizes 4mg of Yohimbine Hydrochloride, which remains the ONLY FDA approved compound for diminished sex drive and libido. (Currently a prescription dosage of Yohimbine HCL is 5 mg.).

Also included in Stamina-Rx are four key components incorporated for their time-proven ability to enhance sexual performance.

Yohimbe is a tree that grows in Africa, and the natives there have used the crude bark and purified compound to enhance sexual desire and performance. Yohimbe has been used for centuries as an aphrodisiac. It haseven been smoked as a hallucinogen. Nowadays, Yohimbe bark extract is mostly used to treat impotence for men and women.

When ingested, Yohimbe is assimilated into the blood stream, and Yohimbe's energizin g effects come from its ability to increase blood flow to the genitals - and this applies to both men and women. Aside from its aphrodisiac effects, new research also show that Yohimbe has powerful antioxidant effects.

Yohimbine is a FDA approved drug to help erectile dysfunction. If you're confused about Yohimbe and Yohimbine, here's a quick explanation. Yohimbe is the name of a bark, and yohimbe bark contains about 6% alkaloids, and 10 to 15% of that is Yohimbine. Most research is done using Yohimbine and not Yohimbe bark.

In a double blind study involving 182 men with erectile dysfunction, 42mg of yohimbe was administered daily. Within one month, 34% of the participants reported full recovery of sexual function, and 24% reported partial response.

In another study involving 48 men experiencing impotence, 46% reported improvement in sexual functioning, and in a Stanford University study on Yohimbe, the subjects experienced 90% increase in sexual desire in less than one hour.

Finally, in an older, 1977 german study done on Yohimbe using 86 patients with erectile dysfunction, 30mg of yohimbe was administered each day for eight weeks. 71% of the participants responded positively with an overall improvement in sexual function and libido.

L-Arginine can improve immune system, reduce fat, increase wound healing, increase natural production of nitric oxide, leading to a more rigid erection. among many other benefits. What's most interesting is that L-Arginine appears to also help stimulate secretion of HGH.

Gamma Amino Butyric Acid - Increases dopamine levels, igniting a euphoric feeling and increasing sensations during orgasm.

Epimedium Sagitatum (Horny Goat Weed) is also called Ying Yang Huo in Chinese, and has been used to treat kidney, joint, liver, and back disorders, and it's also used as an aphrodisiac. Horny goat has testosterone like effects, stimulating sexual activity, desire, increases sperm production, and stimulates sensory nerves.

Horny Goat Weed has been used as an aphrodisiac for hundreds of years, and research has also proven its effects on improving sexual desire and performance. So how does Horny Goat Weed work? Research has shown that Horny Goat Weed can inhibit an enzyme called acetylcholinesterase (AChE). AChE rapidly stops neurotransmission at cholinergic synapses like those found in the brain and at neuromuscular junctions, which are needed for speedy responses in the neuromuscular system. By inhibiting AChE, Horny Goat Weed supports higher levels of the key cholinergic neurotransmitters
associated with sexual arousal.

There have been much research done on Horny Goat Weed, and its aphrodisiac effects have been well demonstrated in animals and humans.

In a study done by Steven Lamm, M.D, 38 men were administered 2 capsules (2 X 800mg) of herbal complex of epimedium grandiflorum, maca pure (lepidium meyenii), mucuna pruriens, and polypodium vulgare (in short, Horny Goat Weed) for 45 days: 25 were healthy men and 13 were men already taking Vi agra. Another 4 capsules of Horny Goat Weed were taken 1 to 2 hours prior to sexual activities.

The study found 13 of 20 healthy men responded positively to Horny Goat Weed, and 6 of the 13 men already on Viagra also had a positive effect from using Horny Goat Weed. In most cases, the men reported overall improvement in sexual satisfaction and increase in sexual desires.

Stamina-Rx uses a 20:1 extract (5 times stronger than the competition!) to ensure "MAXIMUM Stimulation!"
